    Seabuckthorn (Hippophae rhamnoides L.) has been used to treat high altitude diseases. The effects of five-week treatment with total flavonoids of seabuckthorn (35, 70, 140 mg/kg, ig) on cobalt chloride (5.5 mg/kg, ip)- and hypobaric chamber (simulating 5,000 m)-induced high-altitude polycythemia in rats were measured. Total flavonoids decreased red blood cell number, hemoglobin, hematocrit, mean corpuscular hemoglobin levels, span of red blood cell electrophoretic mobility, aggregation index of red blood cell, plasma viscosity, whole blood viscosity, and increased deformation index of red blood cell, erythropoietin level in serum. Total flavonoids increased pH, pO₂, Sp(O₂), pCO₂ levels in arterial blood, and increased Na⁺, HCO₃⁻, Cl⁻, but decreased K⁺ concentrations. Total flavonoids increased mean arterial pressure, left ventricular systolic pressure, end-diastolic pressure, maximal rate of rise and decrease, decreased heart rate and protected right ventricle morphology. Changes in hemodynamic, hematologic parameters, and erythropoietin content suggest that administration of total flavonoids from seabuckthorn may be useful in the prevention of high altitude polycythaemia in rats.

    Full Text Available This study aims to evaluate the effect of different afforestation models on soil microbial composition in the Loess Plateau in China. In particular, we determined soil physicochemical properties, enzyme activities, and microbial community structures in the top 0 cm to 10 cm soil underneath a pure Hippophae rhamnoides (SS stand and three mixed stands, namely, H. rhamnoides and Robinia pseucdoacacia (SC, H. rhamnoides and Pinus tabulaeformis (SY, and H. rhamnoides and Platycladus orientalis (SB. Results showed that total organic carbon (TOC, total nitrogen, and ammonium (NH4(+ contents were higher in SY and SB than in SS. The total microbial biomass, bacterial biomass, and Gram+ biomass of the three mixed stands were significantly higher than those of the pure stand. However, no significant difference was found in fungal biomass. Correlation analysis suggested that soil microbial communities are significantly and positively correlated with some chemical parameters of soil, such as TOC, total phosphorus, total potassium, available phosphorus, NH4(+ content, nitrate content (NH3(-, and the enzyme activities of urease, peroxidase, and phosphatase. Principal component analysis showed that the microbial community structures of SB and SS could clearly be discriminated from each other and from the others, whereas SY and SC were similar. In conclusion, tree species indirectly but significantly affect soil microbial communities and enzyme activities through soil physicochemical properties. In addition, mixing P. tabulaeformis or P. orientalis in H. rhamnoides plantations is a suitable afforestation model in the Loess Plateau, because of significant positive effects on soil nutrient conditions, microbial community, and enzyme activities over pure plantations.

    Development of an effective and non-toxic radiation countermeasure has been a global challenge, till date. On one hand single molecules have failed due to unacceptable toxicity and on the other hand herbal drugs, though non-toxic, are generally neglected because of issues such as incomplete understanding on mechanisms of actions, efficacy and quality control. In the conventional drug discovery process, a single active constituent is isolated, purified, and standardized, but herbal drugs have complex composition and multiple targeted actions. The assessment of efficacy and toxicity of herbal drugs is, therefore, not as straight forward as in case of single active compound. The completion of genome projects of human, mouse and many other simpler experimental models has opened multiple newer avenues for evaluating the metabolism, safety and efficacy of herbal drugs. The radioprotective properties of leaves of Hippophae rhamnoides L. (common name Seabuckthorn, family Eleagnaceae) were reported (Bala et al., 2009, J Herbs and Med Plants). Administration of SBL-1 (a coded herbal preparation from Seabuckthorn leaves), before whole body exposure to lethal dose of 60 Co-gamma-rays (10 Gy), rendered >90% survivors in mice population, while 100% mortality was observed in non-SBL-1 treated, 60 Co-gamma- irradiated (10 Gy) controls. Though, plant H. rhamnoides is popular for its medicinal and neutraceutical values and finds place is in many traditional medicinal systems world over, its prophylactic use as a radiation countermeasure is novel and needed thorough evaluation. To gain in depth understanding on metabolism and safety of SBL-1, the experimental animals were treated with radioprotective concentration of SBL-1. The genome evaluation was performed at different time intervals after the treatment. This talk highlights some of the prominent molecular pathways and genes affected by SBL-1 treatment in experimental animals. Our study suggested that application of genomics

    Berries of common sea-buckthorn (Hippophaë rhamnoides L.) are well-known and used for their bioactive components, and while there is a considerable amount of research on the leaves as well, their ellagitannins (ETs) have not been a prominent focus of research. We identified and quantified ten major hydrophilic polyphenols, all ETs, in H. rhamnoides leaves and compared their abundance between 58 plant individuals. Of these compounds, hippophaenin C was characterized as a new ellagitannin by various spectrometric methods. The total concentrations of ETs ranged from 42.5 mg g -1 dry weight (DW) to 109.1 mg g -1 DW between individual plants. Among the ETs, hippophaenin C, stachyurin, and casuarinin were on average the most abundant compounds. Sexes did not differ significantly, while cultivars showed variation in some ETs. These results suggest that H. rhamnoides leaves could be a potential and rich source of several ETs.

    Full Text Available Phosphorylation is a reversible switch that regulates the biological activities of the proteins. Although there are ample of reports on the plant phosphoproteome analysis, phosphorylation status of apoplastic proteins has not been investigated profoundly. Here a shotgun proteomics approach was used to identify the phosphoproteins from the apoplast of the Hippophae rhamnoides (Seabuckthorn. A total of 123 phosphoproteins were identified using an SYNAPT G2 quadrupole time-of-flight mass spectrometer (Q-ToF-MS. Functional annotation of the identified phosphoproteins using PANTHER, Gene ontology, and KEGG programs showed that the majority of proteins were associated with the transporter, nucleic acid binding and amino acid metabolic activities. Prediction of secretory nature of the identified proteins using SignalP and SecretomeP servers showed that 56 % of the proteins were secretory, while rest of the 44 % of the proteins were non-secretory. PhosPhAt 4.0 detected 534 putative phosphorylation sites in the 75 unique Arabidopsis annotated proteins, wherein 195 (36% were on the serine residue, 196 (37% were on the threonine residue and 143 (27% were detected on the tyrosine residue. Taken together, our results provide the first insight into the phosphorylation-mediated regulation of apoplastic proteins by cellular processes, which would be helpful in an in-depth understanding of the apoplastic signaling

    Hippophae rhamnoides (sea buckthorn) is a plant belonging to Elaeagnaceae family and is distributed worldwide. It has variety of uses from nutritional food to pharmacological application. The study was aimed to analyse the extract from Hippophae rhamnoides leaves for their possible protective effects against the whole body 60 Co-a-irradiation. The study was performed on six groups of male mice i.e. untreated group, H. rhamnoides extract group, irradiated (2Gy), irradiated (3Gy), H. rhamnoides and irradiated (2Gy) and H. rhamnoides and irradiated (3Gy). In each group micronucleus test was performed utilising bone marrow and peripheral blood. The mice were sacrificed 30 hrs after treatment and analysed for the presence of micronuclei. In the present study, there was no significant increase in the frequency of either micronucleated polychromatic erythrocytes (MNPCEs) or normochromatic erythrocytes (NCE) in H. rhamnoides extract treated group over the negative control group of animals, indicating its non-clastogenic and non-toxic activity in the erythropoietic system. H. rhamnoides extract showed good anti-clastogenic activity against the a-irradiation induced clastogenecity in both the tissues i.e. bone marrow and peripheral blood by reducing the frequency of micronuclei. Also the administration of H. rhamnoides extract along with irradiation was slightly able to increase the frequency of PCE in bone marrow as well as in peripheral blood in comparison to the irradiated group (2Gy and 3Gy) indicating its ability to reduce the toxicity caused by irradiation in the erythropoietic system. Thus the results indicate the non-clastogenic effect of H. rhamnoides leaf extract and significant protective activity against 60 Co-a-irradiation suggesting its pharmacological significance for development of radioprotector.

    Full Text Available Effects of the phenolic fraction from Hippophae rhamnoides fruits on the production of thiobarbituric acid reactive substances (TBARS, a marker of lipid peroxidation and the generation of superoxide anion (O2-∙ in human blood platelets (resting platelets and platelets stimulated by a strong physiological agonist, thrombin were studied in vitro. We also examined antioxidant properties of this fraction against human plasma lipid peroxidation and protein carbonylation induced by a strong biological oxidant, hydrogen peroxide (H2O2 or H2O2/Fe (a donor of hydroxyl radicals. The tested fraction of H. rhamnoides (0.5– 50 µg/mL; the incubation time: 15 and 60 min inhibited lipid peroxidation induced by H2O2 or H2O2/Fe. The H. rhamnoides phenolic fraction inhibited not only plasma lipid peroxidation, but also plasma protein carbonylation stimulated by H2O2 or H2O2/Fe. Moreover, the level of O2-∙ in platelets significantly decreased. In comparative experiments, the H. rhamnoides fraction was a more effective antioxidant than aronia extract or grape seed extract (at the highest tested concentration, 50 µg/mL. The obtained results suggest that H. rhamnoides fruits may be a new, promising source of natural compounds with antioxidant and antiplatelet activity beneficial not only for healthy people, but also for those with oxidative stress-associated diseases.

    Hippophae rhamnoides (Sea buckthorn), a traditionally known plant for nutritional and therapeutic values, is under active investigation for radioprotective properties. This study investigated effects of aqueous leaf extract from H. rhamnoides on (60)Co-γ-radiation induced changes in behavior, oxidative stress and serotonin levels in jejunum and plasma of rats. Conditioned taste aversion (CTA) was chosen as the assay to record behavioral changes and was assessed in terms of saccharine preference ratio (SPR). Whole body (60)Co-γ-irradiation (2 Gy) induced significant nonrecoverable CTA (25.6 ± 3.6% SPR, t(6) = 3.499, p loss in body weight (b.w.). One time treatment with leaf extract before irradiation, countered radiation induced CTA and loss in body weight. The 12 mg/kg b.w. concentration of leaf extract caused complete extinction of CTA [100.3 ± 6.4% SPR, t(6) = 5.879, p < .01] after day 3 and the effect was significantly higher than positive control, Ondansetrone (70.0 ± 8.9% SPR). Treatment with leaf extract before irradiation significantly countered radiation induced (1) decrease in antioxidant protection, (2) increase in levels of corticosterone (CS) in plasma, (3) increase in levels of serotonin in jejunum and plasma. Present investigation demonstrated that H. rhamnoides leaf extract prevented behavioral changes induced at clinical radiation doses. Hippophae leaves are nontoxic and are being consumed as tea and other beverages. CTA in rats is a considered parallel process to nausea and vomiting in human beings. These findings, put together, suggest that dietary supplements from Hippophae leaves could be developed for preventing behavioral changes in subjects exposed to radiation.

    Sea buckthorn (Hippophae rhamnoides) is increasingly used in food supplements due to its dietary and medicinal compounds with a beneficial role in human diet and health. As many other medicinal plants, sea buckthorn can be contaminated with microorganisms which exerts an important impact on the overall quality of the products. Irradiation is an effective method for food preservation because it is able to destroy pathogenic microorganisms keeping the organoleptic and nutritional characteristics of the foods. The objective of the present study was to investigate the application of electron beam irradiation in order to improve the microbiological safety of sea buckthorn. The experimental results indicated that the electron beam treatment might be a good method to remove undesirable microorganisms from sea buckthorn without significant changes in its active principles.

    Petroleum exploitation causes contamination of shrub lands close to oil wells. Soil petroleum contamination affects nutrient release during the litter decomposition of shrubs, which influences nutrient recycling and the maintenance of soil fertility. Hence, this contamination may reduce the long-term growth and stability of shrub communities and consequently, the effects of phytoremediation. Fresh foliar litter of Hippophae rhamnoides, a potential phytoremediating species, was collected for this study. The litter was placed in litterbags and then buried in different petroleum-polluted soil media (the petroleum concentrations were 15, 30, and 45 g kg(-1) dry soil, which were considered as slightly, moderately and seriously polluted soil, respectively) for a decomposition test. The impacts of petroleum contamination on the release of nutrients (including N, P, K, Cu, Zn, Fe, Mn, Ca and Mg) were assessed. The results showed that (1) after one year of decomposition, the release of all nutrients was accelerated in the slightly polluted soil. In the moderately polluted soil, P release was accelerated, while Cu, Zn and Mn release was inhibited. In the seriously polluted soil, Cu and Zn release was accelerated, while the release of the other nutrients was inhibited. (2) The effect of petroleum on nutrient release from litter differed in different periods during decomposition; this was mainly due to changes in soil microorganisms and enzymes under the stress of petroleum contamination. (3) To maintain the nutrient cycling and the soil fertility of shrub lands, H. rhamnoides is only suitable for phytoremediation of soils containing less than 30 g kg(-1) of petroleum.

    To investigate the effect of HRE (Hippophae rhamnoides extract) on oral mucositis induced in rats with MTX. Experimental animals were divided into groups as healthy (HG), HRE+MTX (HMTX), and control group, which received MTX (MTXC). HMTX group received 50 mg/kg HRE while MTXC and HG groups received equivolume distilled water with gavage once a day. After one hour of HRE and distilled water administration, HMTX and MTXC groups received a single dose of oral MTX 5 mg/ kg. This procedure was repeated for one month. The levels of MDA, IL-1β, and TNF-α were found to be significantly higher in the cheek, lower lip, and tongue tissue of the animals receiving MTX, compared with HG and HMTX groups; however, these parameters were lower in the cheek and low lip tissue, and a milder damage ocurred in these tissues, compared with the tongue tissue in MTXC group. No histopathologic damage was observed in the cheek, lower lip, and tongue tissues of the rats treated with HRE. This findings indicate that HRE as a natural product is an important advantage compared with synthetic drugs for prophylaxis of oral mucositis developed due to MTX.

    Technology for utilization of seabuckthorn berries for preparation of fruit leather/bar was optimized by modifying the foam mat drying technique. The conversion of seabuckthorn juice/pulp into foam was standardized by whipping the pulp after addition of CMC @ 0-3% at 5 °C and drying the resultant foam in dehydrator (55 ± 2 °C) to a moisture content of about 12-14%. The fruit bar prepared from sulphited juice/pulp wrapped in a butter paper followed by packing in polyethylene pouches (20 g) and stored at ambient temperature (14.6-26.1 °C) experienced least changes in quality attributes like ascorbic acid (1045.7 mg/100 g vs 997.5 mg/100 g) and carotenoids (80.4 mg/100 g vs 72.3 mg/100 g) as compared to the leather made from the unsulphited pulp. Storage studies indicate that fruit bars are mildly hygroscopic (0.46-0.65) and can be stored within the RH of 46-65% at room temperature.

    Full Text Available Vegetable oils are important elements of the human diet because they contain essential nutritional factors. Due to the manufacturing processes or inadequate conditions of storage, they may also contain lipid oxidation products that are toxic to the body. The purpose of this paper is to test the protective effect of carotenoid-rich extracts obtained from the fruits of Hippophae rhamnoides on crude sunflower, pumpkin and olive oils oxidative processes. In order to evaluate the effect of antioxidant carotenoids, three stages were followed: thermal induction of lipid peroxidation in the presence of AAPH (2,2'-Azobis(2-amidinopropane dihydrochloride; determination of the level of lipid peroxidation in oxidized oils in the presence and absence of antioxidants, by quantifying the concentration of conjugated dienes and malonyl dialdehyde (MDA; determination of the level of lipid peroxidation by evaluating the profile of the fatty acids and the ratio between the saturated and unsaturated fatty acids (UFA / SFA, using an GC-MS method. In the case of sunflower oil, it was observed that sea buckthorn fruit extract significantly decreased MDA concentration but does not significantly reduce the concentration of conjugated dienes. The protective effect of carotenoids is more evident in the case of oil from pumpkin seeds. In the olive oil, unlike the first two types of oils, the carotenoids extract inhibits both the MDA and the conjugated dienes formation to a lesser extent, statistically insignificant. Overall, the ratio UFA / SFA decreases in crude oxidized oils. In the oils in which carotenoids were added was observed an increase in the UFA / SFA ratio. Carotenoids fraction from sea buckthorn fruits, rich in xanthophylls’ esters, possess a good antioxidant effect, protecting vegetable oils against peroxidation processes induced in the presence of AAPH

    Sea buckthorn (Hippophaë rhamnoides ssp. rhamnoides) of varieties 'Terhi' and 'Tytti' and one of wild origin were cultivated in southern and northern Finland, harvested during 2007-2013. Proanthocyanidins (PAs) were analyzed with HILIC UPLC-ESI-MS. The southern and northern samples were separated in the partial least squares discriminant analysis model (four factors, R(2) 0.75, Q(2) 0.70). The total PAs were more abundant in berries from the north (610-970mg/100gDW) than in those from the south (340-450mg/100gDW) (p<0.05). In northern Finland, the length of the growth season as well as the temperature sum and radiation sum of the growth season until harvest were negatively correlated with the total PAs in all the samples but positively with PA oligomers in 'Tytti' and 'Terhi'. In southern Finland no respective correlations were seen. 'Terhi' and 'Tytti' had different trends in the content of total PA and oligomers in overripe stages. Copyright © 2016 Elsevier Ltd.

    A facile one-pot green synthesis of gold nanoparticles (AuNPs) with different geometries was achieved using an underutilized Himalayan bioresource Hippophae rhamnoides. Aqueous leaf (LE) and berry extracts (BE) showed rapid synthesis of monodispersed spherical LEAuNPs (27 ± 3.2 nm) and anisotropic BEAuNPs (55 ± 4.5 nm) within 2 and 15 min, respectively. The Fourier-transform infrared (FTIR) spectroscopy showed involvement of polyphenolics/flavonoids in AuNPs reduction. LE AuNPs (IC 50 49 µg) exhibited higher antioxidant potential than BE AuNPs (IC 50 57 µg). Both BE nanotriangles and LE nanospheres exhibited cytotoxicity against Jurkat cell lines. These nanocatalysts also exhibited effective (80-99%) reductive degradation of structurally different carcinogenic azo dyes. Kinetic studies revealed that BE nanotriangles exhibited higher catalytic efficiency (14-67%) than LE nanospheres suggesting shape-dependent regulation of biological activities. The gas chromatography-mass spectrometry (GC-MS) analysis confirmed conversion of toxic methyl orange dye to non-toxic intermediates. Probable degradation mechanism involving adsorption and catalytic reduction of azo bonds was proposed. The present synthesis protocol provided a facile and energy saving procedure for rapid synthesis of highly stable nanoparticles with significant antioxidant and anticancer potential. This is the first report of H. rhamnoides-mediated green synthesis of multipurpose AuNPs as antioxidant, anticancer and nanocatalytic agents for treatment of dye contaminated waste water and future therapeutic applications.

    Thermal dissipation probe (TDP) was used to continuously measure the sap flux density (F d ) of Pinus tabuliformis and Hippophae rhamnoides individuals in hilly Loess Plateau, from June to October 2015, and the environmental factors, i.e., photosynthetic active radiation (PAR), water vapor pressure deficit (VPD), and soil water content (SWC), were simultaneously monitored to clarify the difference of rainfall utilization between the two tree species in a mixed plantation. Using the methods of a Threshold-delay model, stepwise multiple regression analyses, and partial correlation analyses, this paper studied the process of F d in these two species in response to the rainfall pulses and then determined the effects of environmental factors on F d . The results showed that, with the increase of rainfall, the response percentages of F d in both P. tabuliformis and H. rhamnoides increased at first but then decreased; specifically, in the range of 0-1 mm rainfall, the F d of P. tabuliformis (-16.3%) and H. rhamnoides (-6.3%) clearly decreased; in the range of 1-5 mm rainfall, the F d of P. tabuliformis decreased (-0.4%), whereas that of H. rhamnoides significantly increased (9.0%). The lower rainfall thresholds (R L ) of F d for P. tabuliformis and H. rhamnoides were 6.4 and 1.9 mm, respectively, with a corresponding time-lag (τ) of 1.96 and 1.67 days. In the pre-rainfall period, the peak time of F d of P. tabuliformis converged upon 12:00-12:30 (70%), while the F d of H. rhamnoides peaked twice, between 10:30 and 12:00 (48%) and again between 16:00 and 16:30 (30%). In the post-rainfall period, the peak time of F d of P. tabuliformis converged upon 11:00-13:00 (40%), while that of H. rhamnoides peaked twice, between 12:00 and 13:00 (52%) and again between 16:30 and 17:00 (24%). Among the environmental factors, the rank order of factors associated with the F d of both P. tabuliformis and H. rhamnoides was PAR>VPD, before rainfall. However, the rank order of factors

    Sea buckthorn (Hippophae rhamnoides L.) is a pioneer plant used for land reclamation and an appropriate material for studying the interactions of symbiotic microorganisms because of its nitrogen-fixing root nodules and mycorrhiza. We used high-throughput sequencing to reveal the diversities and community structures of rhizospheric fungi and their link with nitrogen-fixing Frankia harbored in sea buckthorn collected along an altitude gradient from the Qinghai Tibet Plateau to interior areas. We found that the fungal diversities and compositions varied between different sites. Ascomycota, Basidiomycota, and Zygomycota were the dominant phyla. The distribution of sea buckthorn rhizospheric fungi was driven by both environmental factors and the geographic distance. Among all examined soil characteristics, altitude, AP, and pH were found to have significant (p < 0.05) effect on the rhizospheric fungal community. The rhizospheric fungal communities became more distinct as the distance increased. Moreover, co-inertia analysis identified significant co-structures between Frankia and AMF communities in the rhizosphere of sea buckthorn. We conclude that at the large scale, there are certain linkages between nitrogen-fixing bacteria and the AMF expressed in the distributional pattern. © 2017 WILEY-VCH Verlag GmbH & Co.

    This study was aimed at the chemical profiling of flavonoid glycosides in antioxidant (AO) fractions of sea buckthorn (Hippophae rhamnoides) seed. Seed fractions were evaluated for their DPPH, ABTS, superoxide and hydroxyl radical scavenging, ferric reduction, ferrous chelation and xanthine oxidase inhibitory capacities. HPLC-DAD-ESI-MS/MS analytical conditions for the profiling of seed flavonoids were optimized and the AO-rich fraction was analysed. Quercetin-3-O-rutinoside (5.9%), isorhamnetin-3-O-rutinoside (4.9%) and isorhamnetin-3-O-sophroside-7-O-rhamnoside (3.7%) were found as the major flavonoid glycosides in the fraction. Significant amounts of isorhamnetin-3-O-glucoside (2.8%), 3-O-sophroside-7-O-rhamnosides of quercetin (2.4%) and kaempherol (1.3%), and 3-O-glucoside-7-O-rhamnosides of quercetin (1.1%) and isorhamnetin (1.1%) along with their free forms: isorhamnetin (2.7%), quercetin (1.1%) and kaempherol (0.6%) were also found in the fraction. The identification of flavonoids as the major less polar AO phenolics in the seeds was rationalized by demonstrating the high AO activity of isorhamnetin, quercetin, kaempherol and quercetin-3-O-rutinoside.

    Full Text Available Dietary proanthocyanidins (PACs as health-protective agents have become an important area of human nutrition research because of their potent bioactivities. We investigated the retinoprotective effects of PACs from sea buckthorn (Hippophae rhamnoides L. seed against visible light-induced retinal degeneration in vivo. Pigmented rabbits were orally administered sea buckthorn seed PACs (50 and 100 mg/kg/day for 14 consecutive days of pre-illumination and seven consecutive days of post-illumination. Retinal function was quantified via electroretinography 7 days after light exposure. Retinal damage was evaluated by measuring the thickness of the full-thickness retina and outer nuclear layer 7 days after light exposure. Sea buckthorn seed PACs significantly attenuated the destruction of electroretinograms and maintained the retinal structure. Increased retinal photooxidative damage was expressed by the depletion of glutathione peroxidase and catalase activities, the decrease of total antioxidant capacity level and the increase of malondialdehyde level. Light exposure induced a significant increase of inflammatory cytokines (IL-1β, TNF-α and IL-6 and angiogenesis (VEGF levels in retina. Light exposure upregulated the expression of pro-apoptotic proteins Bax and caspase-3 and downregulated the expression of anti-apoptotic protein Bcl-2. However, sea buckthorn seed PACs ameliorated these changes induced by light exposure. Sea buckthorn seed PACs mediated the protective effect against light-induced retinal degeneration via antioxidant, anti-inflammatory and antiapoptotic mechanisms.

    The current work intends to promote the development of the methods for establishing the degree of sterilization with ionizing radiations of the herbs in order to use them for obtaining food supplements, but also to obtaining medicines and cosmetic products. Obtaining the raw material, Sea Buckthorn (Hippophae rhamnoides) leaves, at a high level of sterilization without influencing the quality of active principles, is a desideratum of the economic agents in the area. The employed colorimetric methods have practically no impact on the studied herbs and, in the same time, they provide complex information on the effect of the ionizing radiations. The colorimetric methods allow to develop some models to be used both in the indirect evaluation of the microbial charge, before and after the treatment with ionizing radiations and for establishing the optimal necessary dose. The trials were made on Sea Buckthorn (Hippophae rhamnoides) leaves powder supplied by S.C. HOFIGAL EXPORT-IMPORT S.A. from Bucharest. The validation of the obtained colorimetric model was made through some spectrometric setups from the UV-Vis area, on the contents in: polyphenol carboxylic acids, flavones derivates, redox enzymes of superoxide dismutase type, and in the antioxidant activity

    In the southeast of the Qinghai-Tibetan Plateau of China, sea buckthorn (Hippophae rhamnoides L.), which is a thorny nitrogen-fixing deciduously perennial shrub, has been widely used in forest restoration as the pioneer species. In our study, two contrasting populations from the low and high altitudinal regions were employed to investigate the effects of drought, ultraviolet-B (UV-B) and their combination on sea buckthorn. The experimental design included two watering regimes (well watered and drought stressed) and two levels of UV-B (with and without UV-B supplementation). Drought significantly decreased total biomass, total leaf area and specific leaf area (SLA), and increased root/shoot ratio, fine root/coarse root ratio and abscisic acid content (ABA) in both populations. However, the high altitudinal population was more responsive to drought than the low altitudinal population. On the other hand, elevated UV-B induced increase in anthocyanins in both populations, whereas he accumulation of UV-absorbing compounds occurred only in the low altitudinal population. The drought-induced enhancement of ABA in the high altitudinal population was significantly suppressed in the combination of drought and elevated UV-B. Moreover, significant drought x UV-B interaction was detected on total biomass in both populations, total leaf area and fine root/coarse root in the low altitudinal population, and SLA in the high altitudinal population. These results demonstrated that there were different adaptive responses between two contrasting populations, the high altitudinal population exhibited higher tolerance to drought and UV-B than the low altitudinal population.

    Sea buck thorn a magic plant from Northern areas of Pakistan has multiple uses against various ailments, soil enrichment and environmental purposes. The fruit berries are rich in vitamin C, vitamin A, vitamin E, essential oil, Phytosterol and minerals (Fe, Ca, P, Mn and K). The micro nutrient like vitamin C, oil, phosphorus, magnesium and calcium contents in fruit berries of cultivated sea buck thorn (Hippophae rhamnoides. L. spp. sinensis) harvested at three ripening times were determined using biochemical analysis techniques. Harvesting at different stages of fruit ripening was the primary factor determining maximum expression of these biochemical constituents. Biochemical contents were determined at three fruit developmental stages i.e., unripened stage, medium stage and at full-ripened stage. During this study a decline in vitamin C contents was observed along with the fruit ripening. The oil contents in both seed and pulp increased with fruit ripening. Similarly, the mineral contents like magnesium, calcium and phosphorus contents increases with the fruit ripening in sea buck thorn. The main idea was to identify the maximum expression of biochemical at different stages of fruit maturity. It is concluded that it is better to harvest fruit berries at medium stage of fruit ripening when maximum vitamin C is present. For maximum oil and mineral contents fruit must be harvested at ripening stage. The fruit mesocarp is the area where all genes related with micro nutrients are active at one time i.e., when fruit is maturing, hence the characterization of gene expression activities at this stage may help in the isolation of these genes for future commercial use.

    Full Text Available Background and objectives: Hippophae rhamnoides L. known as sea buckthorn is a deciduous medicinal shrub belonging to Elaeagnaceae family. In this study, the most important chemical constituents of sea buckthornwere evaluated in wild populations of central Alborz Mountains in Iran during the growth season of 2014 and 2015. Methods: Phytochemical analysis of fruit pulp and seed oil traits was performed using different methods of chromatography such as spectrophotometry, HPLC and GC. Results: Based on the results of combined analysis of variance, significant (p≤0.01 difference ranges between populations were found in respect to fruit dry weight (21.32 to 32.03%, total phenolic compounds (20.78 to 34.60 mg/g, extractable tannin (1.99 to 5.74 mg/g, glucose (38.14 to 110.70 mg/g, total carotenoids (0.80 to 1.17 mg/g, lycopene (0.13 to 0.20 mg/g, β-carotene (0.18 to 0.26 mg/g, total flavonoids (0.98 to 2.80 mg/g, total soluble solids (TSS (11.85 to 31.50%, vitamin C (1.47 to 8.96 mg/g, seed oil content (4.51 to 7.91%, and two major unsaturated fatty acids including linoleic acid (28.71 to 37.44% and linolenic acid (21.52 to 28.28%. Factor analysis based on principal component analysis (PCA revealed most important traits with the highest correlation factor such as vitamin C, carbohydrates, TSS, fruit dry weight (FDW, and tannin for the first component. Conclusion: content of vitamin C was the main variable in chemical constituents for effective detection of original wild populations of central Alborz Mountains. Accordingly, sea buckthorn populations were divided into four main clusters and groups with high diversity based on their chemical compositions.

    The purpose of this work was to improve the oral bioavailability of a poorly soluble functional food ingredient, the total flavones of Hippophaë rhamnoides L. (TFH). A self-microemulsion drug delivery system (SMEDDS) was developed to overcome the problems of poor absorption of TFH in vivo. The optimal SMEDDS significantly enhanced the solubility of TFH up to 530 times compared to that in water. The mean droplet size was 61.76 nm with uniform distribution. And the loaded system was stable at 25 °C for 3 mo with transparent appearance. The in vitro release of TFH from SMEDDS was faster and more complete than that from suspension. After oral administration of TFH-SMEDDS in rats, the relative bioavailability of TFH was dramatically improved for 3.09 times compared with the unencapsulated form. The investigation indicated the potential application of SMEDDS as a vehicle to improve the oral bioavailability of TFH. The lipid-based nanotechnology, namely self-microemulsion drug delivery system (SMEDDS) was used to improve the bioavailability and oral delivery of total flavones of Hippophaë rhamnoides L. (TFH). The relevant bioavailability of TFH could be remarkably 3-fold improved by the optimized SMEDDS. The SMEDDS produced via a simple one-step process for poorly soluble TFH to achieve a significant improvement in the bioavailability, may endorse the promising utilization of TFH in functional foods as well as pharmaceutical fields with an enhanced absorption in vivo. © 2017 Institute of Food Technologists®.

    Till date no approved radio-protective agent is available world over. WR-2721 had severe side effects and was behaviourally toxic even at sub-lethal doses of ionizing radiation. Seabuckthorn (Hippophae rhamnoides L.) is known for its nutraceutical and therapeutic values. Our studies demonstrated that treatment with leaves of H. rhamnoides rendered > 90% whole body radioprotection in 60 Co-g-irradiated (10 Gy) mice population in comparison to 100% death in non-Hippophae treated irradiated (10 Gy) mice population. Our studies also demonstrated that treatment with leaves of H. rhamnoides prevented conditioned taste aversion (CTA) in irradiated (2 Gy) Sprague-Dawley rats. The present study was planned to evaluate the effects of aqueous extract of Hippophae leaves on changes in levels of neurotransmitters ((acetylcholine esterase (AChE) and dopamine (DA)) in plasma and brain, haematological parameters in blood/plasma; and brain histology in Sprague-Dawley rats showing CTA after 60 Co-g-irradiation (2 Gy). The results showed that whole body 60 Co-g-irradiation (2 Gy) (i) increased the levels of Ach, Eepinephrine (E) and norepinephrine (NE); oxidative stress (MDA and NO), and (ii) decreased the levels of DA; WBC counts and RBC counts and antioxidants (GSH), in comparison to untreated control. Treatment with 12 mg/kg b.w. drug concentration, prior to irradiation significantly (p<0.05) (i) decreased the levels of AChE, E and NE, and MDA and NO levels in plasma and brain, and (ii) increased the WBC counts; RBC counts and levels of antioxidants (GSH), in comparison to radiation control group. Histological changes in brain were also recorded. The results demonstrated that Hippophae leaves extract had neuro-protective and reduced oxidative stress in brain of whole body irradiated mice and could be, thereby contributing to behavioural protection.

    Hippophae rhamnoides L. ssp. turkestanica (Elaeagnaceae) is a predominantly dioecious and wind-pollinated medicinal plant species. The mature fruits of the species possess antioxidative, anti-inflammatory, antimicrobial, anticancerous, and antistimulatory properties that are believed to improve the immune system. The identification of male and female plants in H. rhamnoides ssp. turkestanica is quite difficult until flowering which usually takes 3-4 years or more. A sex-linked marker can be helpful in establishing the orchards through identification of genders at an early stage of development. Therefore, we studied the genetic diversity of populations in Ladakh with the aim to identify a gender-specific marker using ISSR markers. Fifty-eight ISSR primers were used to characterize the genome of H. rhamnoides ssp. turkestanica, of which eight primers generated 12 sex-specific fragments specific to one or more populations. The ISSR primer (P-45) produced a fragment which faithfully segregates all the males from the female plants across all the three valleys surveyed. This male-specific locus was converted into a SCAR. Forward and reverse primers designed from this fragment amplified a 750-bp sequence in males only, thus specifying it as an informative male-specific sex-linked marker. This SCAR marker was further validated for its capability to differentiate gender on an additional collection of plants, representing three geographically isolated valleys (Nubra, Suru, and Indus) from Ladakh region of India. The results confirmed sex-linked specificity of the marker suggesting that this conserved sequence at the Y chromosome is well preserved through the populations in Ladakh region. At present, there are no reliable markers which can differentiate male from female plants across all the three valleys of Ladakh region at an early stage of plant development. It is therefore envisaged that the developed SCAR marker shall provide a reliable molecular tool for early

    Full Text Available To investigate the effects of temperature sum on vitamin C concentration (Vc, yield and maturity of sea buckthorn fruit (Hippophae rhamnoides L. and to predict the optimal harvest time, berries were collected from eight genotypes at an interval of about one week from August 16 to December 2. Maturity was visually observed, berry weight measured and Vc determined. Berries matured at 1165-1316 degree-days (d.d.. Vc reached maximum at about 1229 d.d., while fruit size and yield reached maximum at 1380 d.d.. Mathematical models of polynomial equations were highly significant for predicting the effects of temperature sum on Vc, maturity and fruit yield. Optimal harvest time for maximizing Vc, yield or economic income could be determined according to differential equations. Great variations in Vc, fruit maturity and fruit size suggested good opportunities for selection and breeding. Low rank correlations in vitamin C concentration during fruit maturity, however, call for special attention in selection and breeding.

    Four flavonol glycosides were isolated from an extract of sea buckthorn pomace (Hippophaë rhamnoides) by Sephadex LH-20 gel chromatography and semipreparative HPLC. Their structures were elucidated by hydrolysis studies, ESI-MS(n), UV, and (1)H and (13)C NMR spectroscopy. The occurrence of the major flavonol glycoside kaempferol 3-O-beta-sophoroside-7-O-alpha-rhamnoside in sea buckthorn is described here for the first time. A further 21 flavonol glycosides of Sephadex LH-20 fractions of sea buckthorn pomace were characterized by HPLC-DAD-ESI-MS. The characteristic MS-MS and MS(3) fragmentation pattern of flavonol glycosides previously identified in sea buckthorn juice and of flavonol glycosides identified by NMR spectroscopy gave valuable indications for their identification. The results demonstrate that loss of the sugar moiety from C-7 of the aglycon is more favored than fission of the glycosidic linkage at the C-3 position. Thus, most of the compounds identified were 7-rhamnosides of isorhamnetin, kaempferol, and quercetin, which exhibit different substitution patterns at the C-3 position, mainly glucosides, rutinosides, and sophorosides. In addition, numerous flavonol glycosides were detected lacking a sugar moiety at C-7. Finally, eight flavonol derivatives were identified that are acylated by hydroxybenzoic or hydoxycinnamic acids.

    Centrifugal Partition Chromatography (CPC), a liquid-liquid preparative chromatography using two immiscible solvent systems, benefits from numerous advantages for the separation or purification of synthetic or natural products. This study presents the on-line hyphenation of CPC-Evaporative Light Scattering Detector (CPC-ELSD) with High Performance Liquid Chromatography-UV (HPLC-UV) for the fractionation of flavonols from a solvent-free microwave extract of sea buckthorn (Hippophaë rhamnoides L., Elaeagnaceae) berries. An Arizona G system was used for the fractionation of flavonoids by CPC and a fused core Halo C18 column allowed the on-line analyses of collected fractions by HPLC. The on-line CPC/HPLC procedure allowed the simultaneous fractionation step at preparative scale combined with the HPLC analyses which provide direct fingerprint of collected fractions. Thus the crude extract was simplified and immediate information on the composition of fractions could be obtained. Furthermore, this methodology reduced the time of post-fractionation steps and facilitated identification of main molecules by Mass Spectrometry (MS). Rutin, isorhamnetin-3-O-rutinoside, isorhamnetin-3-O-glucoside, quercetin-3-O-glucoside, isorhamnetin-rhamnoside, quercetin and isorhamnetin were identified. CPC-ELSD/HPLC-UV could be considered as a high-throughput technique for the guided fractionation of bioactive natural products from complex crude extracts. Copyright © 2011 Elsevier B.V.

    Two contrasting sea buckthorn (Hippophae rhamnoides L.) populations from low and high altitude regions were employed to investigate the effects of prevailing and enhanced ultraviolet-B (UV-B) radiation on plant growth and physiological properties under a UVB-enhanced/exclusion system. The experimental design included three UV-B regimes, including excluded (-UVB), near-ambient (NA) and enhanced UV-B (+UVB) radiation. Compared with the control (-UVB), NA caused the formation of smaller but thicker plant leaves in both sea buckthorn populations, paralleled with significant increments of carotenoids and UV-absorbing compounds as well as improved water economy. NA also induced more biomass partition from shoot to root, but CO2 assimilation rate (A), photosynthetic area and biomass accumulation were unaffected. The low-altitude population seemed sensitive to +uvB, as indicated by the decreases in total biomass, A and ascorbic acid content (Asa, an antioxidant) compared with NA. However, little +UVB effect occurred on the high-altitude population, and we suggest that the higher tolerance of this population could be associated with its specific morphological and physiological characteristics, such as small but thick leaves and high-level of Asa content, as well as its greater physiological modification in response to NA, e.g., increases in protective compounds (carotenoids and UV-absorbing compounds) and improvement in water economy, in comparison to the low-altitude population, which form an effective adaptation strategy to enhanced UV-B stress

    Full Text Available A healthy human diet requires the daily consumption of fruits and vegetables rich in bioactive compounds. Sea buckthorn berries (Hippophae rhamnoides L. and apricot fruits (Prunus armeniaca L. are cultivated and appreciated in Romania both as fresh fruits and as derived products. Characterized by a complex chemical composition, sea buckthorn is rich in unsaturated lipids, carotenoids and tocopherols. Except for β-carotene content, less is known about other lipophilic compounds in apricot fruits. The aim of this paper was to separate and quantify the individual carotenoids, tocopherols and tocotrienols in sea buckthorn, apricot pulp and kernels and also to determine the antioxidant activity of the lipophilic extracts using the TEAC  method.  Chemical characterization of lipophilic extract was performed by HPLC with PDA and fluorescence detection. The total carotenoid content was 17.19±1.4 mg/100g F.W. in sea buckthorn; 3.51±0.25 mg/100g F.W. in apricot fruits and 0.58±0.04 mg/100 g F.W. in apricot kernels. The major carotenoids in sea buckthorn were β-carotene, zeaxanthin and β-cryptoxanthin esters. Apricots fruits are rich in β-carotene and its geometric isomers while in kernels we could properly identified only lycopene. The α-tocopherol concentration was higher in sea buckthorn (46 mg/kg than in apricot fruits (1.09 mg/kg while apricot kernel contain large amounts of γ-tocopherol (111 mg/kg. Sea buckthorn fruits showed the highest antioxidant capacity, correlated with a high content of both tocopherols and carotenoids.

    Full Text Available The occurrence of Phellinus hippophaëicola H. Jahn, a fungal pathogen of Hippophaë rhamnoides L., on the Pobrzeże Szczecińskie coastland, NW Poland, was surveyed during 2015–2016. Altogether 59 localities of Phellinus hippophaëicola were recorded, including the first Polish inland locatlities on cultivated plants of Hippophaë rhamnoides. The localities are from 18 ATPOL grid squares, including 43 localities on the Baltic Sea coast. Phellinus hippophaëicola occurred at 74% of all the localities of Hippophaë rhamnoides examined, and at ca 84% of the plant’s natural sites. These findings, and also the status of Hippophaë rhamnoides as a protected species occurring in protected habitats in Natura 2000 sites, mean that Phellinus hippophaëicola is not a rare and endangered species in Poland. In total, 69 localities located in 28 ATPOL grid squares, including the localities reported here, are currently known from Poland.

    Hippophae rhamnoides L., (common name Seabuckthorn; Family: Elaeagnaceae) is a plant growing naturally as well as cultivated in North-West Himalayas at 7000-15,000 feet. It is known for antioxidant and medicinal properties. Our earlier studies showed that administration of SBL-1 (30 mg/kg body weight), 30 minutes before 60 Co-γ-radiation (10 Gy, lethal dose) rendered > 90% survival in mice population. The present study was planned to investigate the effects of radioprotective dose (30 mg/kg body weight) dose of SBL-1 treatment in kidneys of irradiated and control animals. Strain 'A' male mice (weighing 28±2 g) were irradiated without or 30 minutes after administration of SBL-1. Animals were sacrificed at different days (1, 2, 3, 5, 7 and 15) after the treatment. Histopathology and biochemical assays were performed using standardized procedures. Gene expression study was performed by PCR of mRNA. The 60 Co γ-irradiated animals showed a significant reduction in total thiol (T-SH) content till day 5 (p< 0.05), activity of catalase, superoxide dismutase (SOD) (p<0.01) and glutathione-s-transferase (GST) (p<0.05) and significant increase in LPx, ALP and free iron content (p<0.05) on all study days. Histopathology showed Glomeruli shrinkage, nuclear degeneration, tubular dilations, widening of tubular lumen and collapsing of cellular architecture which increased from day 2 till day 7. Significant alterations in mRNA levels of some of the key genes involved in acute renal failure were observed. In animals treated with SBL-1 before irradiation the T-SH increased significantly at day 2, 3 and 5, activity of catalase, SOD and GST decreased significantly (p<0.05) only at day 2 and 3 respectively. Significant increase in (p<0.05) LPx was observed till day 3, ALP levels only at day 3 while free iron content till day 5. Only mild changes in the tissues histology were observed at day 2, 5 and 7. By day 10 no significant difference was observed in comparison to

    The sensory quality and chemical constituents of juices from seven sea buckthorn (Hippophaerhamnoides L.) varieties were studied in two consecutive seasons. The juices were generally described as sour and astringent, with low sweetness and fruity flavor. The differences in sensory quality as well as in chemical composition between samples and years were significant (p acid (malic and quinic acids) from 3.1 to 5.1 g/100 mL, vitamin C from 29 to 176 mg/100 mL, and pulp oil from 0.7 to 3.6%. The soluble solids were between 7.4 and 12.6, the pH between 2.7 and 2.9, and the titrable acidity between 2.0 and 3.7. The redness was highest on Avgustinka and Raisa, but there were no differences in yellowness. Total sugar and the sugar/acid ratio correlated positively with sweetness and negatively with sourness and astringency, whereas total acid and titrable acidity correlated positively with sourness and astringency and negatively with sweetness.

    Radiation-induced gastrointestinal syndrome, including nausea, diarrhea and dehydration, contributes to morbidity and mortality after medical or industrial radiation exposure. No safe and effective radiation countermeasure has been approved for clinical therapy. In this study, we aimed to investigate the potential protective effects of seabuckthorn pulp and seed oils against radiation-induced acute intestinal injury. C57/BL6 mice were orally administered seabuckthorn pulp oil, seed oil and control olive oil once per day for 7 days before exposure to total-body X-ray irradiation of 7.5 Gy. Terminal deoxynucleotidyl transferase dUTP nick end labeling, quantitative real-time polymerase chain reaction and western blotting were used for the measurement of apoptotic cells and proteins, inflammation factors and mitogen-activated protein (MAP) kinases. Seabuckthorn oil pretreatment increased the post-radiation survival rate and reduced the damage area of the small intestine villi. Both the pulp and seed oil treatment significantly decreased the apoptotic cell numbers and cleaved caspase 3 expression. Seabuckthorn oil downregulated the mRNA level of inflammatory factors, including tumor necrosis factor-α, interleukin (IL)-1β, IL-6 and IL-8. Both the pulp and seed oils elevated the level of phosphorylated extracellular-signal-regulated kinase and reduced the levels of phosphorylated c-Jun N-terminal kinase and p38. Palmitoleic acid (PLA) and alpha linolenic acid (ALA) are the predominant components of pulp oil and seed oil, respectively. Pretreatment with PLA and ALA increased the post-radiation survival time. In conclusion, seabuckthorn pulp and seed oils protect against mouse intestinal injury from high-dose radiation by reducing cell apoptosis and inflammation. ALA and PLA are promising natural radiation countermeasure candidates.

    Full Text Available Sea-buckthorn pomace is a very valuable product which contains not only important nutrients but also high-quality oils. The question addressed in the present study was to what extent the diet containing the sea-buckthorn pomace would affect the viscosity and colour of egg yolk measured in the CIELAB system. The feeding mixture for laying hens was supplemented with 20; 50 and 100 g∙kg-1 of sea-buckthorn pomace. As a result, colour indices of the egg yolk such as L*, a* and b* changed significantly (α = 0.01. The greatest relative enhancement was observed for indicator a* for the red colour. Visually, this corresponds to the more intense orange colour of the egg yolk. The addition of sea-buckthorn pomace to the diet for laying hens resulted in a larger increase in indicator ∆E* (CIE total colour difference compared to the control group. Colour indicator hab is the only indicator whose value oscillated around that determined for the control group. The addition of sea-buckthorn pomace to the diet resulted in an increase in colour indices a*, b* and C*ab. Indicator ∆E* also increased significantly with an increasing amount of sea-buckthorn pomace in a diet. Egg yolks were darker, had more intense red and yellow colours, and showed lower viscosity which are all features preferred by the consumer.

    Hippophae rhammnoides L. commonly known as seabuckthorn is a temperate shrub and native of Asia and Europe. It has high antioxidant potential and is known to the traditional Indian, Chinese and Tibetan medicinal system for treatment of multiple disorders viz., circulatory and digestive disorders, hepatic injuries, neoplasia etc. One time treatment with the standardized leaf extract from H. rhammnoides (SBL-1) before whole body irradiation with 60 Co (10 Gy), rendered more than 90% survival in non SBL-1 treated irradiated animals (J herbs, spices medi plants, 2009). Present study investigated the effects of SBL-1 treatment on chromosomal damage in human peripheral blood lymphocytes (PBL), with or without 60 Co-gamma-radiation. The lymphocytes were isolated from the blood drawn from different donors. The isolated lymphocytes were divided into several groups: Group 1-untreated control, Group 2-irradiated (2 Gy), Group 3, 4 and 5 were treated with different concentration of SBL-1, 30 min. after irradiation with 60 Co-gamma-rays (2 Gy). Group 6 was treated with the maximum concentration of SBL-1 used in the study. The metaphase spreading technique was used as per standard procedure to record chromosome breaks, dicentrics, acentrics and rings. The results were also recorded in terms of total aberrant metaphase and frequency of aberrant metaphase per 100 cells. In comparison to the untreated control, in the irradiated PBL culture, there was 8-fold increase in breaks, 211-folds in dicentrics, 75-folds in acentrics and 3-folds in rings (average data). SBL-1 alone at the highest concentration did not cause any significant change in number of breaks, dicentrics, acentrics and rings. The radiation induced aberrations decreased significantly by treatment with SBL-1 and the maximum decrease was observed when the cells were treated with 22μg/ml of SBL-1. These results demonstrated the anti-clastogenic activity of SBL-1 against gamma radiation induced damage. (author)

    Essential oils from the seed, pulp, and leaf of sea buckthorn were obtained with hydrodistillation, and their phytochemical composition was analyzed through gas chromatography-mass spectrometry. Furthermore, the antibacterial activity of the oils was tested on five food-borne bacteria by spectrometry and evaluated in terms of minimum inhibitory concentration. The results indicate that the composition of all essential oils is dominated by free fatty acids, esters, and alkanes. Minimum inhibitory concentration values on each bacterium were obtained for oils from different parts. The oils from different parts exhibited nearly equal inhibitory effect on Staphylococcus aureus. The pulp oil was found to be the most effective for the rest of bacteria tested except Escherichia coli, on which seed oil shows twice the inhibitory effect to that of leaf or pulp oil. Three natural inhibitory examples were found comparable with or even better than the positive control: pulp oil on Bacillus subtilis, and pulp oil and leaf oil on Bacillus coagulans.

    Sea buckthorn has gained importance as a versatile nutraceutical, due to its high nutritive value in terms of carotenoids content. β-Lactoglobulin (β-LG) is a natural carrier for various bioactive compounds. In this study, the effect of thermal treatment in the temperature range of 25 to 100 °C for 15 min on the complex formed by β-LG and carotenoids from sea buckthorn was reported, based on fluorescence spectroscopy, molecular docking and molecular dynamics simulation results. Also, the berries extracts were analyzed for their carotenoids content. The chromatographic profile of the sea buckthorn extracts revealed the presence of zeaxanthin and β-carotene, as major compounds. The Stern-Volmer constants and binding parameters between β-LG and β-carotene were estimated based on quenching experiments. When thermally treating the β-LG-carotenoids mixtures, an increase in intrinsic and extrinsic fluorescence intensity up to 90 °C was observed, together with blue-shifts in maximum emission in the lower temperature range and red-shifts at higher temperature. Based on fluorescence spectroscopy results, the unfolding of the protein molecules at high temperature was suggested. Detailed information obtained at atomic level revealed that events taking place in the complex heated at high temperature caused important changes in the β-carotene binding site, therefore leading to a more thermodynamically stable assembly. This study can be used to understand the changes occurring at molecular level that could help food operators to design new ingredients and functional foods, and to optimize the processing methods in order to obtain healthier food products.

    Full Text Available Recent studies have shown the benefits of tomatoes, seabuckthorn juices and pumpkin oil, rich in bioactives with antioxidant capacity, in the prevention of prostate diseases. To stabilize their antioxidant activity, microencapsulation represent a good technological alternative, improving the stability and bioavailability of bioactive molecules ( phenolic derivatives, carotenoids, phytosterols, vitamins.   The aim of the study was to prepare and characterize microspheres and microcapsules based on emulsions made of natural polymers like Natrium alginate mixed with tomato and/or seabuckthorn juices, with or without pumpkin oil.  The viscosity of emulsions, the morphology of microcapsules and microspheres were characterized comparatively and the bioactives were monitored by UV-Vis spectrometry.  In the lipophilic extract there were identified, before and after encapsulation, different classes of compounds, from lipids, to phenolic acid derivatives, flavonoids and carotenoids. Carotenoids were the major components having concentrations from 9.16 up to 19.71 mg/100 g sample. The viscosity of  each emulsion including juices, oil and natrium alginate 2%, before encapsulation, showed differences, dependent on the oil addition and speed of homogenization. The macroscopic and microscopic structure of microspheres and microcapsules were comparatively evaluated. Both microspheres and microcapsules had external diameters  ranging from 750 to 900 μm and the microcapsules’ oily core of 150-180 μm. The results obtained from emulsion’s viscosity will be correlated with the rigidity and optimal release rate of bioactive molecules from microcapsules and microspheres.  Further studies are directed towards these aspects.

    Full Text Available The seabuckthorn carpenterworm moth Eogystia hippophaecolus is a major threat to seabuckthorn plantations, causing considerable ecological and economic losses in China. Transcriptomic analysis of E. hippophaecolus previously identified 137 olfactory proteins, including three pheromone-binding proteins (PBPs. We investigated the function of E. hippophaecolus PBP1 by studying its mRNA and protein expression profiles and its binding ability with different compounds. The highest levels of expression were in the antennae, particularly in males, with much lower levels of expression in the legs and external genitals. Recombinant PBP1 showed strong binding to sex-pheromone components, suggesting that antennal EhipPBP1 is involved in binding sex-pheromone components during pheromone communication.

    The effects of vitamin E and Hippophea rhamnoides L. extract (HRe-1) on nicotine-induced oxidative stress in rat heart were investigated. There were eight rats per group and supplementation period was 3 weeks. The groups were: nicotine [0.5 mg kg(-1)day(-1), intraperitoneal (i.p.)]; nicotine plus vitamin E [75 mg kg(-1)day(-1), intragastric (i.g.)]; nicotine plus HRe-1 (250 mg kg(-1)day(-1), i.g.); and the control group (receiving only vehicles). Nicotine increased the malondialdehyde level, which was prevented by both vitamin E and HRe-1. Glutathione peroxidase (GPx) activity in nicotine plus vitamin E supplemented group was higher than the others. Glutathione S-transferase (GST) activity in nicotine plus HRe-1 supplemented group was increased compared with the control group. Catalase activity was higher in nicotine group compared with others. GPx activity in nicotine plus vitamin E supplemented group was elevated compared with the others. Total and non-enzymatic superoxide scavenger activities in nicotine plus vitamin E supplemented group were lower than nicotine plus HRe-1 supplemented group. Superoxide dismutase (SOD) activity was higher in nicotine plus HRe-1 supplemented group compared with others. Glutathione reductase activity and nitric oxide level were not affected. Increased SOD and GST activities might have taken part in the prevention of nicotine-induced oxidative stress in HRe-1 supplemented group in rat heart. Flavonols such as quercetin, and isorahmnetin, tocopherols such as alpha-tocopherol and beta-tocopherol and carotenoids such as alpha-carotene and beta-carotene, reported to be present in H. rhamnoides L. extracts may be responsible for the antioxidant effects of this plant extract. 2010 John Wiley & Sons, Ltd.

    Seabuckthorn carpenter moth, Eogystia hippophaecolus (Hua, Chou, Fang, & Chen, 1990), is the most important boring pest of sea buckthorn (Hippophae rhamnoides L.) in the northwest of China. It is responsible for the death of large areas of H. rhamnoides forest, seriously affecting the ecological environment and economic development in northwestern China. To clarify the potential distribution of E. hippophaecolus in China, the present study used the CLIMEX 4.0.0 model to project the potential distribution of the pest using historical climate data (1981-2010) and simulated future climate data (2011-2100) for China. Under historical climate condition, E. hippophaecolus would be found to be distributed mainly between 27° N - 51° N and 74° E - 134° E, with favorable and highly favorable habitats accounting for 35.2% of the total potential distribution. Under future climate conditions, E. hippophaecolus would be distributed mainly between 27° N - 53° N and 74° E - 134° E, with the possibility of moving in a northwest direction. Under these conditions, the proportion of the total area providing a favorable and highly favorable habitat may decrease to about 33%. These results will help to identify the impact of climate change on the potential distribution of E. hippophaecolus, thereby providing a theoretical basis for monitoring and early forecasting of pest outbreaks.

    2018-03-01

    Full Text Available Various parts of sea buckthorn [Elaeagnus rhamnoides (L. A. Nelson], particularly the berries, known also as seaberries, or Siberian pineapples, are characterized by a unique composition of bioactive compounds: phenolic compounds, vitamins (especially vitamin C, unsaturated fatty acids, and phytosterols such as beta-sitosterol. These berries, together with the juices, jams, and oils made from them, have a range of beneficial antioxidant, anti-inflammatory, and anticancer effects. This short review discusses whether sea buckthorn may represent a “golden mean” for the treatment of cancers: It has anti-proliferation properties and can induce apoptosis and stimulate the immune system, and sea buckthorn oil counteracts many side effects of chemotherapy by restoring kidney and liver function, increasing appetite, and keeping patients in general good health. Although the anticancer activity of sea buckthorn has been confirmed by many in vitro and animal in vivo studies, the treatment and prophylactic doses for humans are unknown. Therefore, greater attention should be paid to the development of well-controlled and high-quality clinical experiments in this area.

    As an important ethnic medicine, sea buckthorn was widely used to prevent and treat various diseases due to its nutritional and medicinal properties. According to the Chinese Pharmacopoeia, sea buckthorn was originated from H. rhamnoides, which includes five subspecies distributed in China. Confusion and misidentification usually occurred due to their similar morphology, especially in dried and powdered forms. Additionally, these five subspecies have vital differences in quality and physiological efficacy. This paper focused on the quick classification and identification method of sea buckthorn berry powders from five H. rhamnoides subspecies using multi-step IR spectroscopy coupled with multivariate data analysis. The holistic chemical compositions revealed by the FT-IR spectra demonstrated that flavonoids, fatty acids and sugars were the main chemical components. Further, the differences in FT-IR spectra regarding their peaks, positions and intensities were used to identify H. rhamnoides subspecies samples. The discrimination was achieved using principal component analysis (PCA) and partial least square-discriminant analysis (PLS-DA). The results showed that the combination of multi-step IR spectroscopy and chemometric analysis offered a simple, fast and reliable method for the classification and identification of the sea buckthorn berry powders from different H. rhamnoides subspecies.

    The PBAN (pheromone biosynthesis activating neuropeptide)/pyrokinin peptides comprise a major neuropeptide family characterized by a common FXPRL amide at the C-terminus. These peptides are actively involved in many essential endocrine functions. For the first time, we reported the cDNA cloning and sequence determination of the PBAN from the seabuckthorn carpenterworm, Holcocerus hippophaecolus, by using rapid amplification of cDNA ends. The full-length cDNA of Hh-DH-PBAN contained five peptides: diapause hormone (DH) homolog, α-neuropeptide (NP), β-NP, PBAN, and γ-NP. All of the peptides were amidated at their C-terminus and shared a conserved motif, FXPR (or K) L. Moreover, Hh-DH-PBAN had high homology to the other members of the PBAN peptide family: 56% with Manduca sexta, 66% with Bombyx mori, 77% with Helicoverpa zea, and 47% with Plutella xylostella. Phylogenetic analysis revealed that Hh-DH-PBAN was closely related to PBANs from Noctuidae, demonstrated by the relatively higher similarity compared with H. zea. In addition, real-time quantitative PCR (qRT-PCR) analysis showed that Hh-DH-PBAN mRNA expression peaked in the brain-subesophageal ganglion (Br-SOG) complex, and was also detected at high levels during larval and adult stages. The expression decreased significantly after pupation. These results provided information concerning molecular structure characteristics of Hh-DH-PBAN, whose expression profile suggested that the Hh-DH-PBAN gene might be correlated with larval development and sex pheromone biosynthesis in females of the H. hippophaecolus. 2013 Wiley Periodicals, Inc

The Himalayan mountains provides a significant geographical barrier to the Qinghai-Tibetan Plateau, dividing the Himalayan area into two regions with Nepal to the south and Tibet to the north. There is no information on how the Himalayan mountains influence gene flow and population differentiation of alpine plants. In this study, we analyzed eight nuclear microsatellite markers and cpDNA trnT-trnF regions to test the role of the Himalayan mountains as a barrier to gene flow between populations of H. tibetana. We also examined the fine-scale genetic structure within a population of H. tibetana on the north slope of Mount (Mt. Everest. For microsatellite analyses, a total of 241 individuals were sampled from seven populations in our study area (4 from Nepal, 3 from Tibet, including 121 individuals that were spatially mapped within a 100 m × 100 m plot. To test for seed flow, the cpDNA trnT-trnF regions of 100 individuals from 6 populations (4 from Nepal, 2 from Tibet were also sequenced. Significant genetic differentiation was detected between the two regions by both microsatellite and cpDNA data analyses. These two datasets agree about southern and northern population differentiation, indicating that the Himalayan mountains represent a barrier to H. tibetana limiting gene flow between these two areas. At a fine scale, spatial autocorrelation analysis suggests significant genetic structure within a distance of less than 45 m, which may be attributed mainly to vegetative reproduction and habitat fragmentation, as well as limited gene flow.

    Background: Ionizing radiation affect living tissue by causing majority of in vivo damage by free radical production. Earlier we reported that our preparation from Hippophae leaf offered survival benefit to >90% mice population which was whole body irradiated ( 60 Co-a-rays, 10 Gy). Objective: This study was planned to examine the protective effects of our drug (from Hippophae leaf) on ( 60 Co-a-ray induced oxidative damage and histopathological changes in jejunum. Methods: Around 2 months old adult male Strain 'A' mice were irradiated (10 Gy). Drug was administered intraperitoneally (-30 mm.). Histological parameters were studied after staining the sections with hematoxylin and eosin. Malondialdehyde formation (index of lipid peroxidation), alkaline phosphatase activity, and total thiol content were determined by biochemical techniques. The data was obtained at different time interval upto 30 days. Results: Biochemical studies showed that in comparison to the untreated controls, in the irradiated (10 Gy) mice, there was significant increase in the alkaline phosphatase activity and level of malondialdehyde whereas decrease in total thiol content within 2 days. Histological studies showed that whole body irradiation (10 Gy), damaged the jejunam crypt cells and decreased the villi height within 2 days. Intra-peritoneal administration of drug, 30 mm prior to irradiation, protected the crypt cells and villi height, countered the radiation induced increase in alkaline phosphatase activity and lipid peroxidation and values were comparable to the level of control in 30 days. Conclusions: These biochemical and histopathological studies suggested that our drug can offer effective radioprotection against the oxidative damage to jejunum in vivo. (author)

    Hippophae rhamnoides subsp. sinensis Rousi, Hippophae gyantsensis (Rousi) Y. S. Lian, Hippophae neurocarpa S. W. Liu & T. N. He and Hippophae tibetana Schlechtendal are typically used under one name "Shaji", to treat cardiovascular diseases and lung disorders in Tibetan medicine (TM). A complete set of infrared (IR) macro-fingerprints of these four Hippophae species should be characterized and compared simply, accurately, and in detail for identification. In the present study, tri-step IR spectroscopy, which included Fourier transform IR (FT-IR) spectroscopy, second derivative IR (SD-IR) spectroscopy and two-dimensional correlation IR (2D-IR) spectroscopy, was employed to discriminate the four Hippophae species and their corresponding extracts using different solvents. The relevant spectra exhibited the holistic chemical compositions and variations. Flavonoids, fatty acids and sugars were found to be the main chemical components. Characteristic peak positions, intensities and shapes derived from FT-IR, SD-IR and 2D-IR spectra provided valuable information for sample discrimination. Principal component analysis (PCA) of spectral differences was performed to illustrate the objective identification. Results showed that the species and their extracts can be clearly distinguished. Thus, a quick, precise and effective tri-step IR spectroscopy combined with PCA can be applied to identify and discriminate medicinal materials and their extracts in TM research.

    Hippophae rhamnoides has diverse therapeutic applications in Indian, Chinese and Tibetan medicine. Our earlier studies have shown that pretreatment with Hippophae leaf extract rendered >90% survival in mice population. The objective of this study was to investigate the role of our herbal preparation from Hippophae leaf against radiation induced kidney damage. The study was conducted with Strain 'A' male mice weighing approximately 28 ±2 g. The mice were administered Hippophae leaf extract, 30 minutes prior to 60 cobalt-gamma irradiation. The weight of kidneys and histological changes in kidney tissues at the light microscopic level were examined at 2, 5, 7, 10 and 15 days after treatment. The results showed that no significant change was observed in kidney weight after 60 cobalt-gamma irradiation. The glomerular damage in the form of glomerular sclerosis and percentage of damaged glomeruli; tubular damage in form of tubular dilations; apoptosis, and interstitial hemorrhages in renal cortex was also observed after radiation treatment. The pretreatment with Hippophae leaf extract countered most of the histological alterations induced by radiation. In comparison to radiation alone group, there was a significant decrease (p 60 cobalt gamma radiation induced damage. (author)

    Root xylem anatomical structure and hydraulic traits of three typical shrubs, i.e., Salix psammophila, Caragana korshinskii and Hippophae rhamnoides, within two soil layers (0-20 cm and 30-50 cm) were compared. The results showed that S. psammophila had a higher leaf water potential than C. korshinskii and H. rhamnoides, the average maximum and minimum lumen diameter (d(max) and d(min), respectively), the average lumen area of vessels (Alum) and the ratio of lumen area of all vessels to xylem area (Aves/Axyl) in S. psammophila roots were also significantly higher than those in C. korshinskii and H. rhamnoides, and the root vessel density (VD) in S. psammophila was the same as that in H. rhamnoides but significantly higher than that in C. korshinskii. Root hydraulic conductivity in S. psammophila was 5 times of C. korshinskii and 2.8 times of H. hamnoides. The vulnerability index in S. psammophila roots was similar to that in C. korshinskii but higher than that in H. hamnoides. S. psammophila belonged to a water-spending species, whereas both C. korshinskii and H. rhamnoides were water-saving species, and C. korshinskii was more drought-resistant than H. rhamnoides. There was no difference of d(max), d(min) and Alum between roots in two soil layers, but roots within in the 30-50 cm soil layer had larger VD and Aves/Axyl. The root specific hydraulic conductivity within the 30-50 cm soil layer was significantly higher than within the surface soil layer, whereas the vulnerability index within the 30-50 cm soil layer was smaller, indicating roots in deep soil layers had higher hydraulic transport efficiency and lower hydraulic vulnerability.

    Staphylococcus epidermidis is one of the most frequent causes of biofilm-associated infections on indwelling medical devices. With the emergence of methicillin-resistant S. epidermidis (MRSE), there is an urgent need to discover novel active agents against a range of Gram-positive pathogens. We screened the clinical isolates of S. epidermidis for susceptibility/resistance against commonly prescribed antibiotics. Furthermore, we tested some natural agents alone and in combination with antibiotics to find possible synergistic antimicrobial effects. S. epidermidis clinical isolates were screened for susceptibility/resistance against vancomycin, erythromycin, tetracycline, chloramphenicol, ampicillin, ofloxacin, cephalexin, and gentamicin using the Kirby-Bauer disk diffusion method. The antimicrobial potential of Camellia sinensis, Juglans regia, and Hippophae rhamnoides alone and in combination with antibiotics were examined using the disk diffusion method, where the antimicrobial potential activity was measured in terms of formation of zones of inhibition. Most S. epidermidis isolates were found to be resistant to one or more antibiotics. Gentamycin and ofloxacin were found to be the most effective antibiotics against S. epidermidis isolates. Extracts of Hippophae rhamnoides, Juglans regia, and Camellia sinensis were found to be equally effective against S. epidermidis isolates. In combination with antibiotics, these extracts exhibited appreciable synergistic activity; the highest synergistic activity was observed with erythromycin and cephalexin. In the case of cephalexin, a reversion in resistance was observed. The plant extracts used in the study exhibited additive and synergistic antibacterial activity against S. epidermidis, hence providing an effective alternative to deal with the problem of multidrug resistance.

    Plant water use patterns reflect the complex interactions between different functional types and environmental conditions in water-limited ecosystems. However, the mechanisms underlying the water use patterns of plants in the alpine desert of the Qinghai–Tibet Plateau remain poorly understood. This study investigated seasonal variations in the water sources of herbs (Carex moorcroftii, Astragalus adsurgens) and shrubs (Artemisia oxycephala, Hippophae rhamnoides) using stable oxygen-18 isotope methods. The results indicated that the native herbs (C. moorcroftii, A. adsurgens) and one of the shrubs (A. oxycephala) mainly relied on water from the shallow layer (0–30 cm) throughout the growing season, while the introduced shrub (H. rhamnoides) showed plasticity in switching between water from shallow and deep soil layers depending on soil water availability. All studied plants primarily depended on water from shallow soil layers early in the season. The differences of water use patterns between the introduced and native plants are closely linked with the range of active root zones when competing for water. Our findings will facilitate the mechanistic understanding of plant–soil–water relations in alpine desert ecosystems and provide information for screening introduced species for sand fixation. - Highlights: • Stable oxygen-18 in soil water experienced great evaporation enrichment. • H. rhamnoides experiences a flexible plasticity to switch between shallow and deep soil water. • Native plants mostly relied on shallow and middle soil water. • Water-use patterns by introduced-native plants are controlled by root characteristics.

    A successful radioprotector is the one, which essentially renders protection from the multi-organ dis-function syndrome (MODS) caused by the total body exposure to ionizing radiation. Our rationale is that and instead of a single molecule, a group of molecules/compounds working synergistically can combat the MODS more effectively. Plant extracts offer natural combinations of a plethora of compounds, which act through different mechanisms and are, therefore, the ideal choice. Plants of Himalayan regions have survived under extreme climatic conditions through millions of years and are expected to harbor a battery of anti-stress adaptive molecules offering survival benefits. Our group is actively engaged in developing composite herbal radioprotective preparations from Himalayan Plants. This group is working to develop radiation countermeasures by tapping the essential complex phytochemicals from the plants inhabiting extreme climatic zones of Himalayas. In our laboratory, systematic studies were undertaken to investigate some of these plants located at high altitude regions of Himalayas viz. Hippophae rhamnoides, Rhodiola imbricata and Podophylium hexandruin. The most effective preparation from each of these plants individually, could provide more than 80% survival benefit to the irradiated (10 Gy) mice population against zero per cent survival in non-drug treated irradiated (10 Gy) mice population. It was observed that whole extracts of plant provided much better protection than the partial extracts/fractions. It was also observed that some of the partial extracts/fractions although, provided much higher survival benefits, yet were found to be unsuitable for drug development due to much higher mutagenic and/or recombinogenic effects in comparison to the whole extracts, One of the preparations from leaves of Hippophae rhamnoides (drug) showed more than 90% survival benefits in the irradiated mice population. Only one time intra-peritoneal administration of the drug

    Sea buckthorn ( Hippophae rhamnoides ) -derived products have traditionally been used as food and medicinal ingredients in Eastern countries. The purpose of this study was to investigate the effect of oral intake of sea buckthorn oil products on tear secretion using a murine dry eye model. Orally administered sea buckthorn pulp oil (not seed oil) restored aqueous tear secretion to its normal value under a dry eye condition. Palmitoleate (C16:1), a fatty acid present in sea buckthorn pulp oil, preserved tear secretion and suppressed inflammatory cytokines in the lacrimal gland to the same extent as that by pulp oil. These results suggest that an oral intake of sea buckthorn pulp oil has a potency to preserve tear secretion capacity in the dry eye state and palmitoleate, its main constituent fatty acid, is an active component of the oil. This effect may enable a potent diet-based treatment for the prevention of dry eye.

    The impacts of petroleum contamination on the litter decomposition of shrub-grass land would directly influence nutrient cycling, and the stability and function of ecosystem. Ten common shrub and grass species from Yujiaping oil deposits were studied. Litters from these species were placed into litterbags and buried in petroleum-contaminated soil with 3 levels of contamination (slight, moderate and serious pollution with petroleum concentrations of 15, 30 and 45 g/kg, respectively). A decomposition experiment was then conducted in the lab to investigate the impacts of petroleum contamination on litter decomposition rates. Slight pollution did not inhibit the decomposition of any litters and significantly promoted the litter decomposition of Hippophae rhamnoides, Caragana korshinskii, Amorpha fruticosa, Ziziphus jujuba var. spinosa, Periploca sepium, Medicago sativa and Bothriochloa ischaemum. Moderate pollution significantly inhibited litter decomposition of M. sativa, Coronilla varia, Artemisia vestita and Trrifolium repens and significantly promoted the litter decomposition of C. korshinskii, Z. jujuba var. spinosa and P. sepium. Serious pollution significantly inhibited the litter decomposition of H. rhamnoides, A. fruticosa, B. ischaemum and A. vestita and significantly promoted the litter decomposition of Z. jujuba var. spinosa, P. sepium and M. sativa. In addition, the impacts of petroleum contamination did not exhibit a uniform increase or decrease as petroleum concentration increased. Inhibitory effects of petroleum on litter decomposition may hinder the substance cycling and result in the degradation of plant communities in contaminated areas. Copyright © 2015.

    This study aimed to identify drought-mediated differences in amino nitrogen (N) composition and content of xylem and phloem in trees having different symbiotic N(2)-fixing bacteria. Under controlled water availability, 1-year-old seedlings of Robinia pseudoacacia (nodules with Rhizobium), Hippophae rhamnoides (symbiosis with Frankia) and Buddleja alternifolia (no such root symbiosis) were exposed to control, medium drought and severe drought, corresponding soil water content of 70-75%, 45-50% and 30-35% of field capacity, respectively. Composition and content of amino compounds in xylem sap and phloem exudates were analysed as a measure of N nutrition. Drought strongly reduced biomass accumulation in all species, but amino N content in xylem and phloem remained unaffected only in R. pseudoacacia. In H. rhamnoides and B. alternifolia, amino N in phloem remained constant, but increased in xylem of both species in response to drought. There were differences in composition of amino compounds in xylem and phloem of the three species in response to drought. Proline concentrations in long-distance transport pathways of all three species were very low, below the limit of detection in phloem of H. rhamnoides and in phloem and xylem of B. alternifolia. Apparently, drought-mediated changes in N composition were much more connected with species-specific changes in C:N ratios. Irrespective of soil water content, the two species with root symbioses did not show similar features for the different types of symbiosis, neither in N composition nor in N content. There was no immediate correlation between symbiotic N fixation and drought-mediated changes in amino N in the transport pathways. © 2012 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Full Text Available Random amplified polymorphic DNA (RAPD markers were used to characterize a part of a sea buckthorn gene bank collected for plant breeding purposes. Molecular markers were generated in 55 cultivars and accessions, representing five subspecies of Hippophae rhamnoides L. and intraspecific hybrids between different subspecies. Sixty-three markers were used to generate a Dice's similarity coefficient matrix of pairwise comparisons between individual RAPD profiles. Cluster (UPGMA and principal co-ordinate analyses, based on this matrix, revealed clustering of plants into groups which generally correspond to their taxonomic classification or geographic origin. The analysis of molecular variance (AMOVA was found useful for estimating components of genetic variation between and within taxonomic and geographic groups of accessions and cultivars. Whereas both alternatives for grouping the material (taxonomic or geographic origin resulted in significant between-group variation, the major part of molecular variance (approximately 75% was still attributed to variation within groups. We conclude that the RAPD analysis is useful for clarification of taxonomic and geographic origin of accessions and cultivars of sea buckthorn.

    Spectro colorimetric and GC-MS methods were developed for the quantitative and quality analyze of the fatty acid methyl esters (FAME) and of some natural compounds extracted from the Sea Buckthorn (Hippophae rhamnoides) leaves sterilized by treating them with accelerated electron beams, generated by a linear accelerator. The spectro colorimetric models describe and easy controls the color as it relies on the psycho physics of the color perception and on the simple colorimetric models. Hunter Lab, CIELAB, CIELCH simple colorimetric models are used in developing complex colorimetric models and for the calculation of simple colorimetric models expressed as the total color difference between a sample and a witness, ΔΕ * , ΔΕ C MC, ΔΕ * D IN99, ΔΕ * C IE2000. They provide qualitative data on the deterioration of the active compounds by irradiation. If they are validated by GC-MS methods, they can also provide quantitative data on the radioinduced changes caused to the Sea Buckthorn leaves. The developed GC-MS methods allow the validation of the spectro colorimetric methods for the quantitative and qualitative evaluation of the radioinduced changes in the Sea Buckthorn leaves, reducing both the analyze times and the analyze cost, respectively the random errors of the procedures for extraction and derivation applied to samples preparation

    Flavonoids are important active ingredients in many traditional Chinese medicines. In this paper, capillary electrophoresis with amperometric detection was employed to separate and detect eight flavonoids, rutin, quercetrin, quercetin, kaempferol, kaempferide, catechin, apigenin, and luteolin, in a home-made capillary electrophoresis device. Under the separation voltage of 2000 V, the eight flavonoids could be completely separated within 33 min in 18 mM borax running buffer at pH 10.2. Good linear relationships were obtained for all analytes and the detection limits for flavonoids ranged from 0.46 to 0.85 μM. Then, the method was applied to separate and determine the flavonoids in three traditional Chinese medicines, hippophae rhamnoides, hypericum perforatum, and cacumen platycladi. Finally, rutin, kaempferol, quercetin, and quercetrin were discovered in these medicines and the concentrations ranged from 0.28 to 9.94 mg/g. The recoveries of flavonoids ranged from 84.7 to 113%, which showed the high reliability of this method. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The exposure to ultraviolet radiations (UVR is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS, leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed.

    Development of radioprotective drug is international challenge and till date no radioprotective agent has been approved for human use. Leaf extract of Hippophae rhamnoides, code name SBL-1, was demonstrated to have significant radioprotective properties. Antioxidant properties have contributed significantly to radiation protection potential of many herbs. In this study we have developed simple, sensitive, reliable, rapid and validated HPTLC protocol, for quantification of a major antioxidant 3, 4, 5,-Trihydroxybenzoic acid (Gallic acid ethyl ester) in SBL-1 and also studied the effect of treatment of mice with SBL-1 before total body irradiation (10 Gy, lethal dose) on renal anti-oxidant enzymes. Separation was carried out on silica gel 60F 254 pre-coated TLC aluminum plates, while allowing linear ascending development in twin trough glass chamber, saturated with suitably designed mobile phase. Densitometric detection of Gallic acid was at 280 nm. The protocol produced a discrete band where retention factor was 0.58; correlation coefficient for linear relationship between concentrations and peak areas was 0.9999; detection limits was 25 ng; limits of quantification was 50 ng and percentage recovery was 98.76. Administration of SBL-1 to mice before total body irradiation with lethal dose of low LET 60 Co-gamma rays (10 Gy), resulted in significant countering of the radiation induced disturbances in the levels of Glutathione S-Transferase (GST), Catalase and Superoxide dismutase (SOD) in kidney. This study elucidated an important mechanism of protection to kidney in total body lethally irradiated mice. (author)

    The group of hydrophilic vitamins play an important role in human health, and their lack or excess produces specific diseases. Therefore, the analysis of these compounds is indispensable for monitoring their content in pharmaceuticals and food in order to prevent some human diseases. TLC was successfully applied in the analysis of hydrophilic vitamins, but the most difficult problem in the simultaneous analysis of all these compounds is to find an optimum stationary phase-mobile phase system due to different chemical characteristics of analytes. Unfortunately structural analogues are difficult to separate in one chromatographic run, and this is the case in hydrophilic vitamins investigations. TLC gives the possibility to perform two-dimensional separations by using stationary phase gradient achieving the highest resolution by combining two systems with different selectivity. The goal of this work was to develop a method of analysis enabling separation of hydrophilic vitamins using TLC with adsorbent gradient. The developed method was used for identifying the water-soluble vitamins in alcoholic extracts of Hippophae rhamnoides and of Ribes nigrum. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available Extensive vegetation restoration projects have been widely implemented on the Loess Plateau, China, since 1998. In addition, increasing attention has been paid to the influence of revegetation on soil water. However, the response of the soil water content (SWC to vegetation construction and management has not been adequately studied. In this study, three types of typical artificial vegetation on level bench land were selected, including Pinus tabulaeformis Carr., Prunus sibirica L., and Hippophae rhamnoides Linn., with the natural grassland used as a control group in Wuqi County. The 0–160 cm SWC was monitored biweekly from August 2010 to June 2013 using a portable time domain reflectometry system. The serial autocorrelation test, Mann–Kendall trend test, and prewhitening Mann–Kendall test were employed to systematically analyze the trends in soil water dynamics. The results show that the SWC of the three selected artificial forests/shrub had a significant accumulation process in the 0–160 cm profile during the monitoring period, whereas such an increasing tendency was not observed for natural grassland. Furthermore, the greatest responses were observed in the Pinus tabulaeformis Carr. plantation.

    Infection by Helicobacter pylori has been ascertained to be an important etiologic impetus leading usually to chronic active gastritis and gastric ulcer with growing incidences worldwide. Utilizing as the test pathogen a standard and five clinic strains of Helicobacter pylori, the antibacterial action was assessed in vitro with ethanol extracts of 30 Chinese herbal medicines which have been frequently prescribed since ancient times for treating gastritis-like disorders. Among the 30 tested materials, the ethanol extracts of Abrus cantoniensis (Fabaceae), Saussurea lappa (Asteraceae) and Eugenia caryophyllata (Myrtaceae) were strongly inhibitory to all test strains (MICs: approximately 40 microg/ml), and Hippophae rhamnoides (Elaeagnaceae), Fritillaria thunbergii (Liliaceae), Magnolia officinalis and Schisandra chinensis (Magnoliaceae), Corydalis yanhusuo (Papaveraceae), Citrus reticulata (Rutaceae), Bupleurum chinense and Ligusticum chuanxiong (Apiaceae) substantially active with MICs close to 60.0 microg/ml. As to antibacterial actions of the aqueous extracts of the same drugs, those derived from Cassia obtusifolia (Fabaceae), Fritillaria thunbergii and Eugenia caryophyllata were remarkably inhibitory against all the six Helicobacter pylori strains (MICs: approximately 60 microg/ml). The work compared almost quantitatively the magnitude of the anti-Helicobacter pylori actions of the 30 most prescribed gastritis-treating Chinese herbal drugs, and located as well some source plants where potent anti-Helicobacter pylori phytochemicals could be characterized.

    Grape marc distillates are traditional alcoholic beverages, produced mostly in the Mediterranean countries. The present study proposes the enrichment of a Greek traditional grape marc distillate (tsikoudia) with selected herbs to enhance its natural antioxidants and functional properties. Total phenolic content, the antiradical and antioxidant activities, as well as the phenolic and sugar profiles using NMR and FT-IR spectroscopy were evaluated. The enrichment of distillates with Syzygium aromaticum L., Jasminum officinale L. and Eucalyptus globulus Labill. exhibited the highest total phenolic content as well as the highest antioxidant and antiradical activities, whereas the lowest values were observed with Hippophae rhamnoides L. and Lycium Barbarum Mill. The implementation of NMR and FT-IR spectroscopies attested to the presence of phenolic compounds and of specific carbohydrates in herbal distillates, postulating their migration from selected herbal species to tsikoudia and probably contributing to their organoleptic characteristics. The target of this approach leads to new added-value distillates with enhanced characteristics. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Plots of fresh pulverized fuel ash (PFA, an industrial waste) were inoculated with soils from existing PFA sites and fertilizers in a factorial design, then left unmanaged for 12 years during which time the floral development and soil chemistry were monitored annually. For the first 3 years, the site supported a sparse mix of chenopods (including the scarce Chenopodium glaucum) and halophytes. As salinity declined, ruderals, legumes, and grasses plus the fire-site moss Funaria hygrometrica colonized, followed by Festuca arundinacea grassland (NVC community MG12) and Hippophae rhamnoides scrub. Dactylorhiza incarnata (orchidacea) appeared after 7 years, but only in plots that had received soil from existing orchid colonies. Four years later, a larger second generation of Dactylorhiza appeared, but only in the central zone of the site where vegetation was thinnest. By year 12, the site was dominated by coarse grasses and scrub, with early successional species persisting only in the sparsely vegetated center, where nitrate levels were lowest. This edge effect is interpreted as centripetal encroachment, a process of potentially wider concern for the conservation of low-fertility habitat patches. Overall, seed bank inoculation seems to have introduced few but desirable species (D. incarnata, Pyrola rotundifolia, some halophytes, and annuals), whereas initial application of organic fertilizer had long-lasting ({ge} 10 years) effects on cover and soil composition.

    Full Text Available Observations carried out in May-September 2015 in two sites of Southern Romania reveal a rich spectrum of host plants for Metcalfa pruinosa, which consists of 204 species in 56 families. The species it is noticed on weeds and cultivated plants. The remarkable polyphagia of this species, the lack of natural enemies, and the climatic conditions of 2015 - warm and dry summer, had lead to an invasion of M. pruinosa, in the researched areas; the highest numerical abundances are noticed in shady habitats. Furthermore, on herbs, such as Levisticum officinale, Artemisia dracunculus, Ocimum basilicum, Mentha spp., usually avoided by pests, were observed colonies of the species. It is recorded high numerical abundance on fruit trees and shrubs: Hippophaë rhamnoides, Juglans regia, Prunus cerasus, Vitis vinifera, Rubus idaeus. The harmful effect occurs on apple trees Romus 1 variety as a result of the association with another pest of American origin, Eriosoma lanigerum, situation that favors the attack of the Erwinia amylovora bacteria, causing the collapse of the tree. It is found that altitudes higher than 200 m do not represent a limitative factor in the spreading of species, one of the investigated sites being located at 304 m altitude.

    Full Text Available Sea buckthorn (Hippophae rhamnoides L., Elaeagnaceae. is a thorny shrub that has small, yellow to dark orange, soft, juicy berries. Due to hydrophilic and lipophilic ingredients, berries have been used as food and medicine. Sea buckthorn (SB oil derived from berries is a source of valuable ingredients for cosmeceuticals. The unique combination of SB oil ingredients, in qualitative and quantitative aspects, provides multiple benefits of SB oil for internal and external use. Externally, SB oil can be applied in both healthy and damaged skin (burns or skin damage of different etiology, as it has good wound healing properties. Due to the well-balanced content of fatty acids, carotenoids, and vitamins, SB oil may be incorporated in cosmeceuticals for dry, flaky, burned, irritated, or rapidly ageing skin. There have been more than 100 ingredients identified in SB oil, some of which are rare in the plant kingdom (e.g., the ratio of palmitoleic to γ-linolenic acid. This review discusses facts related to the origin and properties of SB oil that make it suitable for cosmeceutical formulation.

    Single dose of SBL-1 administered at the rate 30 mg/kg body weight (b.w.) 30 min prior to whole body 60 Co-gamma-irradiation at lethal dose (10 Gy), rendered >90% survival in comparison to zero survival in the non-SBL-1 treated 60 Co-gamma-irradiated (10 Gy) mice population (J Herbs Spices Med Plants, 2009; 15(2): 203-215). Present study investigated the effect of SBL-1 on jejunal microbiota in lethally irradiated mice. Study was performed with inbred Swiss albino Strain 'A' male mice (age 9 weeks) weighing 28±2 g. The animals were maintained under controlled environment at 26±2℃; 12 h light/dark cycle and offered standard animal food (Golden feed, Delhi) as well as tap water ad libitum. Metagenomic DNA was extracted, purified and quantified from jejunum of the mice. Universal primers (27f and 1492r) were used to amplify the 16S rRNA DNA from the metagenomic DNA. Amplicons were sequenced, vector contamination and chimeras were removed. The sequences (GenBank Accession No: KF681283 to KF681351) were taxonomically classified by using Sequence Match program, Ribosomal Database Project as well as by nucleotide-BLAST (E-value: 10, database: 16S rRNA gene sequences, Bacteria and Archea). Phylogenetic Tree was prepared using MEGA 5.2 package, using maximum likelihood algorithm after sequence alignment by MUSCLE. Thermus aquaticus was used as out-group to construct rooted tree. Branch stability was assessed by bootstrap analysis. Untreated animals and the animals treated with SBL-1 had 100% Lactobacillus; 60 Co gamma-irradiated animals had 55% Cohaesibacter (Alphaproteobacteria); 27% Mycoplasma (Tenericutes) and only 18% Lactobacillus; animals treated with SBL-1 prior to irradiation had 89% Lactobacillus and 11% Clostridium. This study demonstrated that treatment with SBL-1 at radioprotective doses before total body irradiation with lethal dose (10 Gy) countered the jejunal dysbiosis. (author)

    Full Text Available Chinese sea buckthorn (Hippophae rhamnoides subsp. sinensis has considerable economic potential and plays an important role in reclamation and soil and water conservation. For scientific cultivation of this species across China, we identified the key climatic factors and explored climatically suitable habitat in order to maximize survival of Chinese sea buckthorn using MaxEnt and GIS tools, based on 98 occurrence records from herbarium and publications and 13 climatic factors from Bioclim, Holdridge life zone and Kria' index variables. Our simulation showed that the MaxEnt model performance was significantly better than random, with an average test AUC value of 0.93 with 10-fold cross validation. A jackknife test and the regularized gain change, which were applied to the training algorithm, showed that precipitation of the driest month (PDM, annual precipitation (AP, coldness index (CI and annual range of temperature (ART were the most influential climatic factors in limiting the distribution of Chinese sea buckthorn, which explained 70.1% of the variation. The predicted map showed that the core of climatically suitable habitat was distributed from the southwest to northwest of Gansu, Ningxia, Shaanxi and Shanxi provinces, where the most influential climate variables were PDM of 1.0-7.0 mm, AP of 344.0-1089.0 mm, CI of -47.7-0.0°C, and ART of 26.1-45.0°C. We conclude that the distribution patterns of Chinese sea buckthorn are related to the northwest winter monsoon, the southwest summer monsoon and the southeast summer monsoon systems in China.

    The rapid technological advancement has increased human exposure to ionizing radiations enormously. Ionizing radiations produces deleterious effects in the living organisms. Widespread use of radiation in diagnosis therapy, industry, energy sector and inadvertent exposure during air and space travel, nuclear accidents and nuclear terror attacks requires safeguard against human exposures. Lead shielding and other physical measures can be used in such situations but with difficulty to manage; thus pharmacological intervention could be the most prudent strategy to protect humans against the harmful effect of ionizing radiations. These pharmacological agents are radioprotectives; The development of radioprotective agents has been the subject of intense research in view of their potential for use within a radiation environment. However, no ideal, safe synthetic radio protectors are available to date, so the search for alternative sources including plants has been ongoing. In Ayurveda, the traditional Indian system of medicine, several plants have been used to treat free radical-mediated ailments and, therefore, it is logical to expect that such plants may also render some protection against radiation damage. This all is due to antioxidant enzymes, nitroxides, and melatonin, antiemetic, anti-inflammatory. haemopoitic and immunostimulant compounds. Some of the plants which are found to be radioprotective are Centella asiatica, Ginkgo biloba, Hippophae rhamnoides, Ocimum sanctum, Podophyllurn hexandrum, Tinospora cordifolia, Emblica officinalis, Phyllanthus amarus, etc. So there is an urgent need to identify and characterize the many of the plants in relation to the radioprotection. Besides these medicinal plants there are also some fruits and vegetables which are having good response against harmful radiations such as Kiwifruit Actinidia deliciosa (Actinidaceae), Cape Gooseberry Physalis peruviana (Solanaceae). They protect against the radiation-induced damage by

    Singh, Pawan Kumar; Rawat, Pooja

    Dengue is endemic in more than 100 countries and it is estimated that annually above 390 million infections occur globally. During the period between 1996-2015, a massive increase of more than 500 per cent has been recorded in number of dengue cases reported in India. Till date, there are no specific globally accepted treatments for dengue fever in any system of medicine. Dengue does not cause very high mortality if properly handled and is currently being managed by clinicians through various adjuvant and alternative therapeutic options. Various plant based preparations have been used in different parts of India for combating dengue and are simultaneously also being scientifically validated by researchers. However, number of such scientific validation studies on phytomedicines are very less in India. Out of twenty-two plants reported against dengue, only four have been studied scientifically. Azadirachta indica, Carica papaya, Hippophae rhamnoides and Cissampelos pareira extracts were found effective and demonstrated improvement in clinical symptoms and direct inhibitory effect on dengue virus. C. papaya clinical trial showed increase in platelet count and faster recovery. These plants may be explored further as probable candidates for drug discovery against dengue. There is a need to search more such herbal formulations, which are being practiced at local level, document properly and validate them scientifically to confirm efficacy, mechanistic action and safety, before use. The herbal formulations being used by communities are the low hanging fruits which may provide alternative or adjuvant therapy if proper validation, value addition and product development steps are followed. This paper aims to review the recent status of dengue cases, deaths and evolving curative herbal solutions adapted and reported from India to combat the disease.

    Olas, Beata

    2017-09-01

    Diet and nutrition have an important influence on the prophylaxis and progression of cardiovascular disease; one example is the inhibition of blood platelet functions by specific components of fruits and vegetables. Garlic, onion, ginger, dark chocolate and polyunsaturated fatty acids all reduce blood platelet aggregation. A number of fruits contain a range of cardioprotective antioxidants and vitamins, together with a large number of non-nutrient phytochemicals such as phenolic compounds, which may possess both antioxidant properties and anti-platelet activity. Fresh berries and berry extracts possess high concentrations of phenolic compounds, i.e. phenolic acid, stilbenoids, flavonoids and lignans. The aim of this review article is to provide an overview of current knowledge of the anti-platelet activity of berries, which form an integral part of the human diet. It describes the effects of phenolic compounds present in a number of berries, i.e. black chokeberries - aronia berries (Aronia melanocarpa), blueberries (Vaccinium myrtillus), cranberries (Vaccinium sect. Oxycoccus), sea buckthorn berries (Hippophae rhamnoides) and grapes (Vitis), as well as various commercial products from berries (i.e. juices), on platelets and underlying mechanisms. Studies show that the effects of berries on platelet activity are dependent on not only the concentrations of the phenolic compounds in the berries or the class of phenolic compounds, but also the types of berry and the form (fresh berry, juice or medicinal product). Different results indicate that berries may play a role in the prevention of cardiovascular disorders, but the development of well-controlled clinical studies with berries is encouraged.

    An overwhelming body of research has now firmly established that the dietary intake of berry fruits has a positive and profound impact on human health, performance, and disease. Berry fruits, which are commercially cultivated and commonly consumed in fresh and processed forms in North America, include blackberry ( Rubus spp.), black raspberry ( Rubus occidentalis), blueberry ( Vaccinium corymbosum), cranberry (i.e., the American cranberry, Vaccinium macrocarpon, distinct from the European cranberry, V. oxycoccus), red raspberry ( Rubus idaeus) and strawberry ( Fragaria x ananassa). Other berry fruits, which are lesser known but consumed in the traditional diets of North American tribal communities, include chokecherry ( Prunus virginiana), highbush cranberry ( Viburnum trilobum), serviceberry ( Amelanchier alnifolia), and silver buffaloberry ( Shepherdia argentea). In addition, berry fruits such as arctic bramble ( Rubus articus), bilberries ( Vaccinuim myrtillus; also known as bog whortleberries), black currant ( Ribes nigrum), boysenberries ( Rubus spp.), cloudberries ( Rubus chamaemorus), crowberries ( Empetrum nigrum, E. hermaphroditum), elderberries ( Sambucus spp.), gooseberry ( Ribes uva-crispa), lingonberries ( Vaccinium vitis-idaea), loganberry ( Rubus loganobaccus), marionberries ( Rubus spp.), Rowan berries ( Sorbus spp.), and sea buckthorn ( Hippophae rhamnoides), are also popularly consumed in other parts of the world. Recently, there has also been a surge in the consumption of exotic "berry-type" fruits such as the pomegranate ( Punica granatum), goji berries ( Lycium barbarum; also known as wolfberry), mangosteen ( Garcinia mangostana), the Brazilian açaí berry ( Euterpe oleraceae), and the Chilean maqui berry ( Aristotelia chilensis). Given the wide consumption of berry fruits and their potential impact on human health and disease, conferences and symposia that target the latest scientific research (and, of equal importance, the dissemination of

    In this study, the leaf litters of Populus simonii and other 11 tree species were put into soil separately or in mixture after grinding, and incubated in laboratory to analyze the effects of their decomposition on soil properties and the interactions between the litters decomposition. The decomposition of each kind of the leaf litters in soil increased the soil urease, dehydrogenase, and phosphatase activities and the soil organic matter and available N contents markedly, but had greater differences in the effects on the soil available P content and CEC. The decomposition of the leaf litters of Caragana microphylla and of Amorpha fruticosa showed obvious effects in improving soil properties. The decomposition of the mixed leaf litters of P. simonii and Pinus tabulaeformis, Platycladus orientalis, Robinia pseudoacacia, or Ulmus pumila showed interactive promotion effects on the abundance of soil microbes, and that of the mixed leaf litters of P. simonii and P. orientalis or C. microphylla showed interactive promotion effects on the soil organic matter, available P, and available K contents and soil CEC but interactive inhibition effects on the activities of most of the soil enzymes tested. The decomposition of the mixed leaf litters of P. simonii and Larix principis-rupprechtii showed interactive promotion effects on the activities of most of the soil enzymes and soil nutrient contents, while that of the mixed leaf litters of P. simonii and P. sylvestris var. mongolica showed interactive inhibition effects. Overall, the decomposition of the mixed leaf litters of P. simo- nii and U. pumila, P. tabulaeformis, L. principis-rupprechtii, or R. pseudoacacia could improve soil quality, but the mixed leaf litters of P. simonii and P. orientalis, C. microphylla, P. sylvestris var. mongolica, Hippophae rhamnoides, or A. fruticosa showed an interactive inhibition effect during their decomposition.

    Full Text Available . High performance liquid chromatography (HPLC with UV detection is nowadays the reference method to identify and quantify the biomarkers of quality and authenticity of plants and food supplements. Seven medicinal plants were collected from wild flora: Taraxacum officinalis (1, Cynara scolimus (2, Silybum marianum (3, Hypericum perforatum (4,  Chelidonium majus (5, Lycopodium clavatum (6 and  Hippophae rhamnoides (7  leaves and fruits.  Two products (A and B were obtained by mixing individual plant powders. Therefore product A was obtained by mixing dandelion, artichoke and milk thistle, 1:1:1 while product B by mixing St John’s wort, Celandine and Wolf’s claw, 1:1:1. The methanolic extracts of individual plants as well as three different extracts of products A and B (using acidulated water, neutral water and acidulated methanol were analyzed using HPLC-UV for their phenolics’ fingerprint and composition. The qualitative (untargeted analysis and quantitative (targeted analysis results were further compared using Principal Component Analysis (PCA in order to identify their specific biomarkers. Thus, quantitative evaluation of individual phenolics in case of individual plants and products A and B extracts, showed specific and significant differences of composition. Both products A and B contained elagic acid as major compound. For product A, good biomarkers were trans-cinnamic, chlorogenic, caffeic and p-coumaric acids, as well silymarin and silibine originating from milk thistle. For product B, good biomarkers were quercetin and kaempherol, gallic and protocatecuic acids, this product being rich in flavonoids. In conclusion, HPLC-UV coupled with PCA analysis proved to be a rapid and useful way to identify the main biomarkers of plants’ authentication, as well of final products’ quality and safety.

    Sea buckthorn (Hippophae rhamnoides L.) and St. John's wort (Hypericum perforatum L.) are used as an emmenagog and for the treatment of other gynecological disorders including uterus inflammation and endometriosis. The aim of the present study is to investigate the potential of a mixture of sea buckthorn and St. John's wort oils (HrHp oil) in the treatment of endometriosis. The activity was assessed in surgically induced endometriosis in rats. A 15-mm piece of endometrium was sutured into the abdominal wall. Twenty-eight days later, a second laparotomy was performed to calculate the endometrial foci areas and to score intra-abdominal adhesions. The rats were treated with either vehicle, HrHp oil formulation, or the reference (buserelin acetate). At the end of the experiment all rats were sacrificed and endometriotic foci areas and intra-abdominal adhesions were re-evaluated. The tissue sections were analyzed histopathologically. Peritoneal fluids of the experimental animals were collected in order to detect the levels of tumor necrosis factor-α, vascular endothelial growth factor, and interleukin-6, which might be involved in the etiology of endometriosis. In the HrHp oil-treated group, the volumes of endometriotic implants were found to be significantly decreased (from 50.8 mm 3 to 18.6 mm 3 , pnecrosis factor-α decreased from 7.02±1.33 pg/mL to 4.78±1.02 pg/mL (pvascular endothelial growth factor from 17.39±8.52 pg/mL to 9.67±5.04 pg/mL (ptreatment. HrHp oil may be a promising alternative for the treatment of endometriosis. Copyright © 2016. Published by Elsevier B.V.

    The rapid technological advancement has increased human exposure to ionizing radiations enormously. Ionizing radiations produces deleterious effects in the living organisms. Widespread use of radiation in diagnosis therapy, industry, energy sector and inadvertent exposure during air and space travel, nuclear accidents and nuclear terror attacks requires safeguard against human exposures. Lead shielding and other physical measures can be used in such situations but with difficulty to manage; thus pharmacological intervention could be the most prudent strategy to protect humans against the harmful effect of ionizing radiations. These pharmacological agents are radioprotectives; The development of radioprotective agents has been the subject of intense research in view of their potential for use within a radiation environment. However, no ideal, safe synthetic radio protectors are available to date, so the search for alternative sources including plants has been ongoing. In Ayurveda, the traditional Indian system of medicine, several plants have been used to treat free radical-mediated ailments and, therefore, it is logical to expect that such plants may also render some protection against radiation damage. This all is due to antioxidant enzymes, nitroxides, and melatonin, antiemetic, anti-inflammatory. haemopoitic and immunostimulant compounds. Some of the plants which are found to be radioprotective are Centella asiatica, Ginkgo biloba, Hippophae rhamnoides, Ocimum sanctum, Podophyllurn hexandrum, Tinospora cordifolia, Emblica officinalis, Phyllanthus amarus, etc. So there is an urgent need to identify and characterize the many of the plants in relation to the radioprotection. Besides these medicinal plants there are also some fruits and vegetables which are having good response against harmful radiations such as Kiwifruit Actinidia deliciosa (Actinidaceae), Cape Gooseberry Physalis peruviana (Solanaceae). They protect against the radiation-induced damage by

    . This is because the diffusion of a characteristic pioneer vegetation (mainly represented by Hippophae cf. rhamnoides) helped to confer to the local environment a high ecological stability, buffering vegetation changes. Finally, during the Last Glacial, mixed broad-leaved deciduous and Pinus forests widely occupied the Arno coastal plain, demonstrating that this area acted as an important tree refuge. Local ecological conditions favourable to tree survival were determined mainly by (i) high precipitation, as a function of orographic uplift of air charged with moisture from the nearby Tyrrhenian Sea, (ii) mild temperatures, which were also influenced by proximity to the sea, and (iii) high topographic variability, providing a series of suitable microenvironments.

    Soil erosion control (SEC), carbon sequestration (CAS), and soil moisture (SMO) strongly interact in the semi-arid Loess Plateau. Since SMO has supportive effects on SEC and CAS, it can be considered as ecosystem service (ES), and there is an immediate need to coordinate the relationships among these ecosystem services (ESs) to promote the sustainability of vegetation recovery. In this study, we quantified the ESs, ES trade-offs, and the environmental factors in 151 sample plots in the Ansai watershed, and we used a redundancy analysis (RDA) to clarify the effects of environmental factors on these ESs and their trade-offs. The results were as follows: (1) the general trend in the SEC of vegetation types was Robinia pseudoacacia (CH)>native grass (NG)>small arbor (ST)>Hippophae rhamnoides (SJ)>artificial grass (AG)>Caragana korshinskii (NT)>apple orchard (GY)>crop (CP); the CAS trend was CH>SJ>NT>AG>CP>ST>GY>NG; and the SMO trend was CP>NG>GY>AG>SJ>ST>CH>NT. (2) For SEC-SMO trade-offs, the influence of vegetation type, altitude, silt and sand composition was dominant. The arrangement of NG, AG, and SJ could decrease the extent of the trade-offs. (3) For CAS-SMO trade-offs, vegetation coverage and types were the dominant factors, but the effects were not complex. The extent of these trade-offs was lowest for NT, and that for SJ was the second lowest. (4) Considering the relationships among the three ESs, SJ was the most appropriate afforestation plant. Combing the vegetation types, slope position, slope gradient, and soil properties could regulate these ES relationships. The dominant factors influencing ES trade-offs varied among the different soil layers, so we must consider the corresponding influencing factors to regulate ESs. Moreover, manual management measures were also important for coordinating the ES relationships. Our research provides a better understanding of the mechanisms influencing the relationships among ESs.

    Full Text Available We estimated the nutritive value, vitamin content, amino acid composition, fatty acid content, and mineral profile of a phytococktail comprising sea buckthorn (Hippophae rhamnoides, apricot (Prunus armeniaca, and roseroot (Rhodiola imbricata from trans-Himalaya. The free vitamin forms in the phytococktail were determined by rapid resolution liquid chromatography/tandem mass spectrometry (RRLC-MS/MS. Vitamin E and B-complex vitamins were detected as the principle vitamins. Reversed-phase high performance liquid chromatography (RP-HPLC with pre-column derivatization was used for identification and quantification of amino acids. Eight essential and eleven non-essential amino acids were quantified, and the content ranged between 76.33 and 9485.67 µg/g. Among the essential amino acids, L-methionine, L-phenylalanine, L-lysine, L-leucine, and L-histidine were found to be the dominant contributors. We also quantified the fatty acids in the phytococktail by using gas chromatography coupled with a flame ionization detector (GC-FID with fatty acid methyl esters (FAMEs derivatization. The analysis revealed the presence of 4 major fatty acids contributing to the total lipid content. Palmitic acid was found to be the rich source of saturated fatty acid (SFA and constituted ∼31% of the total lipid content. Among the unsaturated fatty acids (UFAs, palmitoleic acid (43.47%, oleic acid (20.89%, and linoleic acid (4.31% were prominent. The mineral profiling was carried out by inductively coupled plasma optical emission spectrometer (ICP-OES, and it was found to contain a number of important dietary mineral elements. The harsh climatic conditions, difficult terrain, and logistic constraints at high altitude regions of Indian trans-Himalayan cold desert lead to the scarcity of fresh fruits and vegetables. Therefore, the source of multiple vitamins, essential amino acids, fatty acids, and dietary minerals from the phytococktail would provide great health benefit

    Limited health facilities and malnutrition are major problems in the Karakorum Range of Northern Pakistan, often resulting in various human disorders. Since centuries, however, local communities in these areas have developed traditional methods for treating various ailments and local foods capes that can be significant for devising public health and nutritional policies. This study was intended to document the ethnobotanical knowledge of the local peoples in the Tormik Valley, especially in the medical and food domains. Field trips were undertaken in 14 different villages of the study area from 2010 to 2012. Ethnobotanical data were gathered using semi-structured interviews and group conversation with 69 informants. Details about local uses of plant species were recorded along with demographic characteristics of the visited communities. Relative frequency citation index (RFCi) and preference ranking index (PRi) tools were applied to determine the cultural significance of the reported species. Sixty-three plant species, with a predominance of Asteraceae and Fabaceae family members, as well as their detailed folk uses were documented. Forty-three percent of the species were used to treat various diseases, 21 % were consumed as wild fruits and vegetables and 53 % of the species had multipurpose applications. Thymus linearis Benth, Hippophae rhamnoides ssp. turkestanica L. and Convolvulus arvensis L. were found to be the most utilized medicinal plant species, i.e. those with significant RFCi values (0.54, 0.51 and 0.48, respectively). Betula utilis D. Don was the most versatile taxon (seven different ways of utilization); being this species a common and easily accessible subalpine tree and then under anthropogenic pressure, the implementation of concrete strategies aimed at its in-situ and ex-situ conservation is strongly recommended. The valleys in the Karakorum Mountains in the Northern Pakistan host significant Traditional Knowledge on local food and medicinal

    Severe water erosion in the key loess hilly area is affected by the coupling role of rainfall and earth surface features. In this study, rainfall simulation techniques at the micro-plot scale (1.2 m x 1.2 m; 2 m x 1.2 m) was used as the basic measures, the relations between rainfall depth, intensity and runoff-erosion under different plant morphology features as well as micro-landscape positions were quantified and analyzed. Several key findings were captured. Firstly, rainfall depth and intensity both affected water erosion significantly, while the role of the rainfall intensity was more important than that of the depth. Secondly, a strong negative correlation was found between the antecedent soil moisture content and the generation timing of surface runoff, while water erosion had a positive relation with the antecedent soil moisture. Thirdly, different plant morphology and micro-landscape positions of shrub plant (seabuckthorn) played different roles leading to different rates of surface runoff and soil erosion. Dominated by a rainfall intensity ranging from 50 to 60 mm x h(-1), runoff coefficient in those micro-plots covered by seabuckthorn was about 5%-8%, and changed into 25%, 45% and 63% in grassland-plots, bared plots covered by biological-crust and bared plots without any coverage, respectively. Fourthly, the specific landscape position of seabuckthorn in the plots was also found to play a key role in affecting water erosion processes, and seabuckthorn at the lower landscape position, rather than the upper and middle position, played a better buffering role in reducing runoff and soil loss.

    Choosing the soils under different vegetation recovery of Heidaigou dump as the research objects, we mainly analyzed their basic physical and chemical properties and enzyme activities with the method of Analysis of Variance as well as their relations using Pearson correlation analysis and path analysis hoping to uncover the driving factors of the differences between soil enzyme activities under different vegetation restoration, and provide scientific suggestions for the plant selection as well as make a better evaluation to the reclamation effect. The results showed that: (1) Although the artificial vegetation restoration improved the basic physical and chemical properties of the soils while increasing their enzyme activities to a certain extent, the soil conditions still did not reach the level of the natural grassland; (2) Contents of soil organic carbon (SOC) and soil total nitrogen (TN) of the seabuckthorns were the nearest to those of the grassland, which reached 54. 22% and 70. 00% of those of the grassland. In addition, the soil bulk density of the seabuckthorns stand was 17. 09% lower than the maximum value of the amorpha fruitcosa land. The SOC and TN contents as well as the bulk density showed that seabuckthorns had advantages as the species for land reclamation of this dump; Compared with the seabuckthorn, the pure poplar forest had lower contents of SOC and TN respectively by 35.64% and 32.14% and displayed a 16.79% higher value of soil bulk density; (3) The activities of alkaline phosphotase under different types of vegetation rehabilitation had little variation. But soil urease activities was more sensitive to reflect the effects of vegetation restoration on soil properties; (4) Elevation of the SOC and TN turned out to be the main cause for soil fertility restoration and increased biological activities of the dump.

Determination of mineral composition was carried out by flame atomic absorption photometry, vitamin C and pectinaceous substances -by titirimetric methods, phenolic substances and vitamin P - by colorimetric methods. Vitamin C content was minimal in fresh fruits of cornel (6.9±0.3 mg%), amounted to 21.7-32.0 mg% in the fruits of blackberries and medlar and reached 180.1±7.2 mg% in the fruit of sea-buckthorn. Vitamin P concentration ranged from 34.9 (sea-buckthorn) to 180.0 mg% (cornel). Berries of a cornel contained also the greatest number of titrable acids (33.2±1.3 g/dm3), phenolic compounds (243.0±4.8 mg%) and pectinaceous substances (2.91±0.08%). The most significant content of potassium (521±15.6 mg%), calcium (133.2±5.2 mg%), magnesium (62.4±2.5 mg%) and iron (2.81±0.05 mg%) was revealed in medlar fruits. Consumption of 100 g of the studied fruits provides daily requirements of a human body, depending on a species of wild plants: in calcium -for 2-13.3%, potassium - for 7.0-20.8%, magnesium - for 8.1-15.6%, iron - for 5.9-19.2% and in vitamin C - from 5.8-24.6 to 145.7% in the case of sea buckthorn. The applied processing method of conservation - fast freezing (t=-30 °С) of fruits and their long storage (t=-18 °С) is the effective way ensuring high safety of nutrients in them. In the studied berries after 9-months cold storage the safety of vitamin C varied ranging from 55.7 (blackberry) to 76.1% (cornel), and vitamin P - from 81.9 (sea-buckthorn) to 92.8% (cornel). Stability of titrable acids, except for medlar fruits, varied from 84.2% (blackberry) to 94.0% (sea-buckthorn). The safety of phenolic and pectinaceous compounds by the end of 9 months

    Re-vegetation is mainly applied into regeneration in opencast mine to improve the soil quality. It is very important to choose feasible vegetation types for soil restoration. In this study, three typical forest restoration types were studied at Antaibao mine, namely, Medicago sativa, mixed forests Pinus taebelaefolius-Robinia pseudoacacia-Caragana korshinskii and Elaeagnus angustifolia-Robinia pseudoacacia-Caragana korshinskii-Hipophae rhamnoides, to determine the nutrient contents and enzyme activities in different soil layers. The results showed that re-vegetation markedly increased soil nutrient contents and the enzyme activities during the restoration process. The nutrient content of soil in the P. taebelaefolius-R. pseudoacacia-C. korshinskii mixed forest field was significantly higher than those in other plots. It was found that the soil of the P. taebelaefolius-R. pseudoacacia-C. korshinskii mixed forest had the highest integrated fertility index values. In conclusion, the restoration effects of the P. zaebelaefolius-R. pseudoacacia-C. Korshinskii mixed forest was better than that of E. angustifolia-R. pseudoacacia-C. korshinskii-H. rhamnoides, while M. sativa grassland had the least effect.

    Taking the Zhifanggou watershed in Ansai, Shaanxi Province of Northwest China as a study unit, an investigation on the arthropods in 8 forest stands was conducted from 2006 to 2008, with the species-area and species-abundance relationships of the arthropods in these stands analyzed by various mathematical models. In these forest stands, the species-area relationship of the arthropods accorded with the formula S= CAm With the increase of investigation area, the species number approached to a constant, and the corresponding smallest investigation area was in the order of natural bush > natural forest > Populus davidiana+Robinia pseudoacacia forest > Hippaphae rhamnoides +Caragana mocrophylla forest> Periploca sepium forest > Hippaphae rhamnoides forest > Robinia pseudoacacia forest > Caragana mocrophylla forest, indicating that the more complex the stands, the larger the minimum area needed to be investigated. Based on sampling investigation, the species-abundance models of the arthropods in various stands were established. Lognormal distribution model (LN) was most suitable to fit the arthropod community in natural recovery stands, suggesting that in the arthropod community, there were more species with medial individual amount and fewer abundant species and rare species, and no obvious dominant species. LogCauchy distribution model (LC) was most suitable to fit the arthropod community in mixed and pure stands. As compared with natural recovery stand, mixed and pure stands had more abundant and rare species, and more dominant species.

    Full Text Available Sea buckthorn (Hippophae rhamnoides–derived products have traditionally been used as food and medicinal ingredients in Eastern countries. The purpose of this study was to investigate the effect of oral intake of sea buckthorn oil products on tear secretion using a murine dry eye model. Orally administered sea buckthorn pulp oil (not seed oil restored aqueous tear secretion to its normal value under a dry eye condition. Palmitoleate (C16:1, a fatty acid present in sea buckthorn pulp oil, preserved tear secretion and suppressed inflammatory cytokines in the lacrimal gland to the same extent as that by pulp oil. These results suggest that an oral intake of sea buckthorn pulp oil has a potency to preserve tear secretion capacity in the dry eye state and palmitoleate, its main constituent fatty acid, is an active component of the oil. This effect may enable a potent diet-based treatment for the prevention of dry eye.

    Vitamin C or ascorbic acid, a very useful constituent of redox mechanism is used in medicine and also added in manufactured food for anti-oxidation. A UV-spectrophotometric method was used for the determination of Vitamin C in 4 different medicinal plants. High amount of Vitamin C 160 mg/100 g was found in Citrulus colcocynthis, followed by Hippophae rhamonides oil 136.1 mg/100g. A relatively low concentration of Vitamin C was recorded in Glycyrhiza glabra 56.2 mg/100g and Withinia somnifera 51.50 mg/100 g. The presence of high concentration of Vitamin C in selected medicinal plants might be responsible for their therapeutic effects and uses in the traditional system of medicine. (author)

    Natural oils are commonly used in topical pharmaceutical formulations as emulsifiers, stabilizers or solubility enhancers. They are presented as safe and inert components, mainly used for formulation purposes. It is confirmed that natural oils can affect the skin penetration of various substances. Fatty acids are mainly responsible for this effect. Current understanding lacks reliable scientific data on penetration of natural oils into the skin and their skin penetration enhancement potential. In the current study, fatty acid content analysis was used to determine the principal fatty acids in soybean, olive, avocado, sea-buckthorn pulp, raspberry seed and coconut oils. Time of flight secondary ion mass spectrometry bioimaging was used to determine the distribution of these fatty acids in human skin ex vivo after application of the oils. Skin penetration enhancement ratios were determined for a perspective antioxidant compound dihydroquercetin. The results demonstrated skin penetration of fatty acids from all oils tested. Only soybean and olive oils significantly increased the skin distribution of dihydroquercetin and can be used as skin penetration enhancers. However, no correlation can be determined between the fatty acids' composition and skin penetration enhancement using currently available methodological approaches. This indicates that potential chemical penetration enhancement should be evaluated during formulation of topically applied products containing natural oils.

In the course of parodontitis, we determined the intensity of inflammatory-destructive changes (Pi) in the course of periodontitis, the degree of fang denudation, the depth of gum and parodontal recesses, degree of the teeth becoming loose; we conducted the microbiological study of the oral cavity microflora and drew up an antibiotic graph. We included laser therapy in the comprehensive treatment course of generalized parodontitis. We divided the patients into two groups. The patients of the first group were treated in two stages. We used peridex, composed of chlorhexidine for antiseptic treatment of oral cavity. We used a combined solution of sage, eucalyptus, camomile and calendula to irrigate the oral cavity. At the second stage we used ointment applications with the composition of 3% indometacin, heparin, vitamins, sea-buckthorn oil and antibiotics. In the course of comprehensive treatment of the patients of the II group we included laser therapy. Our interest in the laser beam, as in the means of parodontitis treatment was stimulated by a number of properties of the laser beam and namely, its anti-inflammatory, desensitizing and antibacterial action promotes intensifying the reparation processes and does not entail any complications. The mentioned method has produced the best therapeutic results and has resulted in the reduced treatment period.

    Full Text Available Rock dumps of coalmines have high potential for forest regeneration and environmental capacity, which are dependent on the technology of reclamation and the properties of technogenic soils and grounds. Traditional forestry methods for obtaining the main criteria of biological indicators of woody vegetation were used in the study as follows: ground seed germination, seedling planting technology, composition and increment of tree stands, root structure, care harvesting of undergrowth, biotopic classification. Natural overgrowing of dumps is dependent on the availability of seeds and conditions for their germination and subsequent growth. Most of the zonal tree and shrub species are able to colonize and grow on the coalmine dumps. Mineralization of the dumps surfaces without rich soil stratum, porosity of the upper horizon of lithostratum, and low nutrient content (nitrogen give benefits in the growth and subsequent formation of birch, pine and sea-buckthorn stands. Afforestation is the cheapest and most effective method of biological reclamation. The analysis of artificial reforestation shows the probability of targeted plantation cultivation of various tree species. The use of a wide range of tree and shrub species make it possible to create biologically diverse intrazonal technogenic ecosystems with high recreational and economic productivity. Wildfires spreading out in spring season on herbaceous rags limit the overgrowth of the dumps by forest vegetation. Two-year cyclical increment decline of trees due to provocative spring warming takes place. The zoogenic factor, especially zoo chores distribution of berry plants, has essential value for forest forming process. By the results of forest formation analysis at rock dumps, alveolate-hilly technology of mine reclamation was developed, which allows to significantly improve dumps’ afforestation capacity, their biological posttechnogenic diversity and productivity.

    Full Text Available Antioxidant activity was measured by ferric reducing ability of plasma (FRAP assay in seven types of infusions prepared from commercial dried berry fruit products: Rosa canina, Vaccinium vitis-idaea, Hiphophae rhamnoides, Hibiscus sabdariffa and three fruit mixtures. Total polyphenols (TP, total anthocyanins and the polyphenolic compounds were determined by HPLC equipped with diode array detector. To estimate the amount of elements released from fruits into the water extracts, levels of Fe, Mn, Zn and Cu in dried samples and in infusions were determined by flame atomic absorption spectrometry. The correlation between polyphenols content and the antioxidant activities and the microelements in the infusions and the antioxidant activities were estimated using the Pearson’s correlation test. The results showed a high, positive and significant correlation (r = 0.9465 between the FRAP values and TP content, meaning that the concentration of phenolic compounds may be a good indicator of the reducing capacity in the infusions. Correlations varied (positive, negative and weak between antioxidant and mineral extractability of berry infusions. Among the polyphenolic compounds, gallic acid contributed particularly to the antioxidant capacity of the studied samples (r = 0.563. The correlation of antioxidants, total polyphenols with mineral extractability showed the influence of antioxidant compound on mineral bioavailability.

    New studies indicate the presence of early Holocene ice-free areas far north in Scandinavia. Post-glacial fire and vegetation were investigated based on sedimentary charcoal and pollen from two small lakes in northern Sweden. Accumulation of organic sediment started around 10,900 and 9200 cal yr BP, showing that both lake valleys were ice-free extremely early given their northerly location. Fire events started after 9600 cal yr BP and became less common around the '8.2-ka event'. Woody vegetation provided fuel that contributed to fires. The first vegetation in our pollen record consisted of Hippophae, Dryas, grasses and sedges. Subsequently broadleaved trees (Betula, Salix) increased in abundance and later Pinus, Alnus, ferns and Lycopodium characterized the vegetation. Pollen from Larix, Picea and Malus were also found. The change in vegetation composition was synchronous with the decrease in lake-water pH in the region, indicating ecosystem-scale processes; this occurred during a period of net global and regional warming. The changes in fire frequency and vegetation appear independent of regional trends in precipitation. The reconstructed fire history and vegetation support the scenario of early ice-free areas far north in Scandinavia during early Holocene warming, creating favorable conditions for woody plants and wildfires.

    Industrialization of bio-energy relies on the supply of resources on a large scale. The theoretical biomass resources could reach 2.61-3.51 billion tce (tons of coal equivalent)/a in China, while the available feedstock is about 440-640 million tce/a, however, among this only 1.5-2.5% has been transferred into energy at present. Marginal land utilization has great prospects of supplying bio-energy resources in China, with co-benefits, such as carbon sequestration, water/soil conservation, and wind erosion protection. There is a large area of marginal land in China, especially in northern China, including about 263 million ha of desertification land, 173 million ha of sand-land, and 17 million ha of salinizatin land. The plant species suitable to be grown in marginal lands, including some species in Salix, Hippophae, Tamarix, Caragana, and Prunus is also abundant Biomass feedstock in marginal lands would be 100 million tce/a in 2020, and 200 million tce/a in 2050. As a result, a win-win situation of eco-society and bio-energy development could be realized, with an expected 4-5% reduction of total CO{sub 2} emission in China in 2020-2050. Although much progress has been made in the field of bio-energy research in China, yet significant efforts should be taken in the future to fulfill large-scale industrialization of bio-energy.

    Ionizing radiation induces DNA damage and are harmful to mankind. They act through free radical generation, which target the double bonds of all cellular macromolecules. The radiation damage may be classified as probabilistic or deterministic, depending on the dose of radiation exposure. Since radiation affects multiple organs so those drugs which protect many organs, would be more beneficial. In this process herbal extracts, which are cocktail of several phyto-chemicals, would be more promising. Initially sulphur containing bio-molecules were identified as radio-protector, but now many secondary metabolites from plant kingdom, have been reported to be radio-protective. They have different mechanism of action, but most of them either prevent the FR induced DNA damage or accelerate the DNA repair process. Aminofostine, WR-2721, 159243, 2926 are some of the examples. However they have limited use because of associated cytotoxicity. Eicosanoids, topoisornerase inhibitors (e.g. camptothecin, topotecan), and the hypoxia-activated anthraquinone AQ4N have shown radioprotecting potential. Several plant products, derived from Tulsi, Vinca alkaloids, taxans, turmeric, Rubia cordifolia, Semecarpus anacardium and several plants rich in polyphenols and flavones have shown hemotherapeutic potential. Similarly, Hippophae, rhodiola imbricata, Podophyllum hexandrum, Ocimum sancturn, Plumbago zeylanica etc have shown radioprotection. Rubia cordifolia has shown both chemotherapeutic and radioprotective property in rats and A-431 cells. Similarly Semecarpus anacardium extract has shown cell cycle arrest in DU-145 cells. (author)

    This paper took four kinds of common soil and water conservation plants of the study area, Caragana microphylla, Salix psammophila, Artemisia sphaerocephala and Hippophae rhamnides at ages of 4 as the research object. Thirteen indicators, i.e., single shrub to reduce wind velocity ration, shelterbelt reducing wind velocity ration, community reducing wind velocity ration, taproot tensile strength, representative root constitutive properties, representative root elasticity modulus, lateral root branch tensile strength, accumulative surface area, root-soil interface sheer strength, interface friction coefficient, accumulative root length, root-soil composite cohesive, root-soil composite equivalent friction angle, reflecting the characteristics of windbreak and roots, were chose to evaluate the differences of foliage-root coupling soil-reinforcement and anti-erosion among four kinds of plants by analytic hierarchy process (AHP) under the condition of spring gale and summer rainstorm, respectively. The results showed the anti-erosion index of foliage-root coupling was in the sequence of S. psammophila (0.841) > C. microphylla (0.454) > A. sphaerocephala (-0.466) > H. rhamnides (-0.829) in spring gale, and C. microphylla (0.841) > S. psammophila (0. 474) > A. sphaerocephala (-0.470) > H. rhamnides (-0.844) in summer rainstorm. S. psammophila could be regarded as one of the most important windbreak and anti-erosion species, while C. microphylla could be the most valuable soil and water conservation plant for the study area.

    An appreciation of comparative microbial survival is most easily done while evaluating their adaptive strategies during stress. In the present experiment, antioxidative and whole cell proteome variations based on spectrophotometric analysis and SDS-PAGE and 2-dimensional gel electrophoresis have been analysed among salt-tolerant and salt-sensitive Frankia strains. This is the first report of proteomic basis underlying salt tolerance in these newly isolated Frankia strains from Hippophae salicifolia D. Don. Salt-tolerant strain HsIi10 shows higher increment in the contents of superoxide dismutase, catalase and ascorbate peroxidase as compared to salt-sensitive strain HsIi8. Differential 2-DGE profile has revealed differential profiles for salt-tolerant and salt-sensitive strains. Proteomic confirmation of salt tolerance in the strains with inbuilt efficiency of thriving in nitrogen-deficient locales is a definite advantage for these microbes. This would be equally beneficial for improvement of soil nitrogen status. Efficient protein regulation in HsIi10 suggests further exploration for its potential use as biofertilizer in saline soils.

    Full Text Available Abstract Traditional plant use in Nepal has been documented for millennia. The importance of plants as medicine has not diminished in any way in recent times, and traditional medicines are still the most important health care source for the vast majority of the population. This paper examines the ethnobotany and traditional use of plants extracted from the vulnerable alpine zone in the Dolpa, Humla, Jumla and Mustang districts of Nepal. The results of this ethnobotanical study indicate that a very large number of plant species is used as traditional medicines. There were 107, 59, 44 and 166 species of ethnomedicinal importance in surveyed areas of Dolpa, Humla, Jumla and Mustang district respectively. Of these, 84 common species, used at least in two districts, were selected to enumerate their ethnomedicinal properties. The 84 species belonged to 75 genera and 39 families. The commonest species in this pharmacopoeia were: Allium wallichii, Cordyceps sinensis, Dactylorhiza hatagirea, and Rheum australe. A total of 21 species were most common in three districts and 59 in two districts. The genera Aconitum, Allium, Arisaema, Berberis, Corydalis, Gentiana, Hippophae, Juniperus and Rhododendron each possessed two species with ethnomedicinal use. Labiatae was the most medicinally important family with five species used, followed by Araceae, Compositae, Liliaceae, Polygonaceae, Ranunculaceae, Scrophulariaceae and Umbelliferae, each contributing four species.

    Taking four plant species, Caragana korshinskii, Salix psammophila, Hippophae rhamnides and Artemisia sphaerocephala, which were 3-4 years old and in vigorous growth period, as test materials, the anti-fracture forces of lateral-root branches and adjacent upper straight roots were measured with the self-made fixture and the instrument of TY 8000. The lateral-root branches were vital and the diameters were 1-4 mm. The results showed that the anti-fracture force and anti-fracture strength of lateral-root branches were lesser than those of the adjacent upper straight roots even though the average diameter of lateral-root branches was greater. The ratios of anti-fracture strength of lateral-root branches to the adjacent upper straight roots were 71.5% for C. korshinskii, 62.9% for S. psammophila, 45.4% for H. rhamnides and 35.4% for A. sphaerocephala. For the four plants, the anti-fracture force positively correlated with the diameter in a power function, while the anti-fracture strength negatively correlated with diameter in a power function. The anti-fracture strengths of lateral-root branches and adjacent upper straight roots for the four species followed the sequence of C. korshinskii (33.66 and 47.06 MPa) > S. psammophila (17.31 and 27.54 MPa) > H. rhamnides (3.97 and 8.75 MPa) > A. sphaerphala (2.18 and 6.15 MPa).

    result of burn of fire brigade servants and etc. from fat oils, extractions and carotineoids of basil, tarragon and melissa will be continued. As there are much unsaturated double related compounds in the content of basil, melissa and tarragon crops like carotenoids, flavanoids and antosians it is possible to produce medicaments and cremes with protector properties against radioactive irradiations. Because of antioxidant property substances possession in the content of these crops' extractions their application ways in meat and fish canning production of industrial significance will be investigated in future. It is possible to product toothpastes (anticaries diseases) from the oil and extractions obtained of them together with Sea-Buckthorn oil. Constant hybrid basil melissa lines are available to use in food industry as green vegetable.

    The purpose was to study the effect of enriched bakery products in the diet of rats on indicators of prooxidant-antioxidant system of blood serum. Experiment was carried out on male Wistar rats with initial weight 140-180 g. After a quarantine during the preparatory period rats for 14 days were accustomed to the partial (50%) replacement of the standard diet by bakery products with standard compound­ing. Then, 7 groups of rats were formed: the 1st group of rats (control group, n=10) continued to receive bakery products of a standard composition; groups with the 2nd on 7th (experimental, n=8 in everyone) received enriched bakery products: the 2nd group - with blueberry powder; the 3rd group - with mountain ash powder; the 4th group - with sea-buckthorn powder; the 5th group - with flour of a pine nut; the 6th group - with rice bran oil; the 7th group - with pumpkin oil. The intensity of free radical oxidation and antioxidant activity (by chemiluminescence method), activity of superoxide dismutase and level of secondary oxidation products reacted with thiobarbituric acid (by spectrophotometry) were monitored in rat blood serum. It has been shown that the use of bakery products with different compounding in the animal diet had different effects on indicators of prooxidant-antioxidant system of blood serum. Bakery products containing sea buckthorn pomace powder, flour of pine nut and rice bran oil reduced intensity of free radical oxidation in rat blood serum by 36.0, 24.6 and 18.8%, respectively. It is suggested that bakery products containing flour of pine nut products brake a free radical oxidation in rat blood serum in case of simultaneous content of natural antioxidants and melanoidins. The anthocyanins of powder from blueberry berries can render antioxidant effect and slow down formation of by-products of oxidation. No statistically significant change on indicators of prooxidant-antioxidant system of blood serum of rats treated with bakery products with rowan

    Full Text Available Introduction.Cervical erosionsoccur in 12-15%gynaecological diseases. Erosion is a damage of epithelialmucous membrane or skin. Therapy of patients with cervical erosionsis based on selection of pathogeneticsubstantiative method of treatment. Bathes and irrigations with 20% protargol, alum, carbolic acid, potassium permanganate are used. But some authors admit the destructive influence of these procedures. Using of tampons with 10% sintomycine emulsion, cod liver oil, sea-buckthorn oil,kalanchoe sap, propolis, vagotil, cigerol, galantamine also doesn’t give desirable result. Recently polymeric pellicleswith antibacterial substances are widely used. The most perspective in this route are aminoglycoside antibiotics. That is why we chose gentamicine sulfate (broad-spectrum aminoglycoside antibiotic. The aim of study is the development of the optimal composition of vaginal pellicleswith gentamicine sulfate for gynaecological practice, scientifically substantiation of excipients: polymeric base and plasticizer. Results and discussion.Polymeric bases and plasticizers influence on gentamicine sulfate releasing from polimericpellicleshas been studied. Research on choice of optimal composition has been carried out by two-factor experiment plan. The next bases and plasticizers have been used: methylcellulose, sodium carboxymethylcellulose, soluble biopolymer, gelatin; glycerine, propylenglycol, polyethylene glycol, twin 80. Gentamicine sulfate content was 80 mg in one pellicle. Gentamicine sulfate releasing from polimericpellicleshas been investigated by the Kruvchinsky method, concentration of active substance has been detected after 45 min. As a result it has been established that base makes essential influence on the gentamicine sulfate releasing (Fexp.52,88>Ftabl. 3,9. The best plasticizer is glycerin and the most optimal base is gelatin. So the optimal composition for vaginal films has been chosen: Gentamicine sulfate0,08 g Glycerin0,7 g Gelatin0
