  1. Direct detection of saponins in crude extracts of soapnuts by FTIR. (United States)

    Almutairi, Meshari Saad; Ali, Muhammad


    Direct detection of saponins in soapnuts (Sapindus mukorossi) using Fourier transform infrared (FTIR) spectroscopy is investigated in this project. Potassium bromide powder was mixed with extracted powder of soapnuts and compressed to a thin pellet for examination process. The outcome of the FTIR spectra of saponin demonstrated characteristic triterpenoid saponin absorptions of OH, C = O, C-H, and C = C, while the glycoside linkages to the sapogenins were indicated by the absorptions of C-O. The significance of this study is that saponin absorption peaks are directly detectable in crude aqueous and 95% ethanol extracts of soapnuts powder using FTIR spectroscopy, thereby eliminating the need of further expensive and exhaustive purification steps. The extracts of soapnuts were screened for saponins along with controls by phytochemical tests, and advanced spectroscopic techniques such as ultra fast liquid chromatography and ultra performance liquid chromatography quadrupole-time of flight-mass spectrometry were also implemented to validate the saponins.

    Mukhopadhyay, Soumyadeep; Mukherjee, Sumona; Hashim, Mohd Ali; Sen Gupta, Bhaskar


    Colloidal gas aphron dispersions (CGAs) can be described as a system of microbubbles suspended homogenously in a liquid matrix. This work examines the performance of CGAs in comparison to surfactant solutions for washing low levels of arsenic from an iron rich soil. Sodium Dodecyl Sulfate (SDS) and saponin, a biodegradable surfactant, obtained from Sapindus mukorossi or soapnut fruit were used for generating CGAs and solutions for soil washing. Column washing experiments were performed in down-flow and up flow modes at a soil pH of 5 and 6 using varying concentration of SDS and soapnut solutions as well as CGAs. Soapnut CGAs removed more than 70% arsenic while SDS CGAs removed up to 55% arsenic from the soil columns in the soil pH range of 5-6. CGAs and solutions showed comparable performances in all the cases. CGAs were more economical since it contains 35% of air by volume, thereby requiring less surfactant. Micellar solubilization and low pH of soapnut facilitated arsenic desorption from soil column. FT-IR analysis of effluent suggested that soapnut solution did not interact chemically with arsenic thereby facilitating the recovery of soapnut solution by precipitating the arsenic. Damage to soil was minimal arsenic confirmed by metal dissolution from soil surface and SEM micrograph. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Anna E M F M Oliveira

    Full Text Available Pterodon emarginatus Vogel is a Brazilian species that belongs to the family Fabaceae, popularly known as sucupira. Its oil has several biological activities, including potent larvicidal property against Aedes aegypti. This insect is the vector of dengue, a tropical disease that has been considered a critical health problem in developing countries, such as Brazil. Most of dengue control methods involve larvicidal agents suspended or diluted in water and making active lipophilic natural products available is therefore considered a technological challenge. In this context, nanoemulsions appear as viable alternatives to solve this major problem. The present study describes the development of a novel nanoemulsion with larvicidal activity against A. aegypti along with the required Hydrophile Lipophile Balance determination of this oil. It was suggested that the mechanism of action might involve reversible inhibition of acetylcholinesterase and our results also suggest that the P. emarginatus nanoemulsion is not toxic for mammals. Thus, it contributes significantly to alternative integrative practices of dengue control, as well as to develop sucupira based nanoproducts for application in aqueous media.

    Full Text Available Blends of biodiesels produced from soapnut oil and high-oleic free fatty acids (FFAs, which are potential non-edible oil feedstocks, were investigated with respect to their fuel properties. The soapnut oil methyl esters (SNME had satisfactory fuel properties with the exception of its high cold filter plugging point. In contrast, the biodiesel from the FFAs had favorable fuel properties such as a low cold filter plugging point of −6 °C; however, it exhibits poor oxidation stability with an induction period (IP of 0.2 h. The complementary blend of the SNME and the FFA-based biodiesel at various weight ratios was studied to improve the fuel properties. As a result, the biodiesel blend at a weight ratio of 70:30 can successfully meet all the biodiesel specifications, except the marginal oxidation stability. Furthermore, the effectiveness of N,N’-di-sec-butyl-p-phenylenediamine at the concentration between 100 and 500 ppm on the improvement in the oxidation stability of the biodiesel blend was examined. The relationship between the IP values associated with the consumption of antioxidants in the biodiesel blends was described by first-order reaction rate kinetics. In addition, the natural logarithm of IP (ln IP at various concentrations of antioxidant presented a linear relation with the test temperature. The IP at ambient temperature can be predicted based on the extrapolation of the temperature dependence relation.

    Neodymium iron boron (NdFeB) permanent magnets have high energy product with suitable magnetic and physical properties for an array of applications including power generation and motors. However, synthetic routes of NdFeB permanent magnets involve critical procedures with high energy and needs scientific skills. Herein, we report on soapnut extract mediated synthesis of nanoscale cobalt substituted NdFeB (Co-NdFeB) permanent magnetic powders (Nd: 15%, Fe: 77.5%, B: 7.5% and Co with molar ratios: 0.5, 1, 1.5 and 2). A 10 ml of 10% soapnut extract was added to 90 ml of respective chemical composition and heated to 60 °C for 30 min and aged for 24 h. The dried powder was sintered at 500 °C for 1 h. The characterization of the prepared nanoscale Co-NdFeB magnetic powders was done using the techniques such as Dynamic Light Scattering (DLS for size and zeta potential measurements), X-ray diffraction (XRD) for structural determination, Scanning electron microscopy (SEM) with energy dispersion spectroscopy (EDS) for surface morphological and elemental analysis, Fourier transform infrared spectroscopy (FT-IR) for the identification of functional groups associated and hysteresis loop studies to quantify the magnetization. The results revealed that particles were in irregular and tubular shaped and highly stable (Zeta potential: -44.4 mV) with measured size <100 nm. XRD micrographs revealed a tetragonal crystal structure and FTIR showed predominant N-H and O-H stretching indicates the involvement of these functional groups in the reduction and stabilization process of Co-NdFeB magnetic powders. Hysteresis studies signify the effect of an increase in Co concentration.

    Mendes, V S; Sant'Anna, J B; Oliveira, S C C; Maldonade, Iriani Rodrigues; Machado, Eleuza Rodrigues


    Pterodon emarginatus is a tree of the Brazilian Savannah. The beans of this tree are used in folk medicine as anti-inflammatory preparations, especially for infections caused by Staphylococcus aureus . These bacteria can cause simple infections or serious illnesses such as pneumonia, meningitis, endocarditis, toxic shock syndrome, septicemia, and others. This study had the goal of verifying the effect of the essential oil (OE) from P. emarginatus on the inhibition of S. aureus in culture medium, i.e., " in vitro " tests. The vegetable material was cut and crushed with a press. The OE was obtained by extraction using hexane, alcohol, and water. The P. emarginatus extracts obtained were used to evaluate the antimicrobial effect on S. aureus (ATCC 25923) by tests of well diffusion, disc diffusion, and microdilution. The strain used in the assays was maintained in brain heart infusion broth and nutrient agar until testing. Afterward, the bacteria were spread on agar plates with Mueller-Hinton agar medium. In the wells and on the paper discs, the OE suspensions were placed in the following volumes: 10, 15, 20, 25, 30, 40, and 80 μL and subsequently they were incubated at 35°C ± 2°C. After 24 h, the number of colony-forming unit was determined. Pure OE and hydroalcoholic extract inhibited the growth of S. aureus , while aqueous extract had no effect on bacterial growth in all microbial methods used. Thus, the present study showed the potential of sucupira-based extracts against S. aureus growth, opening new perspectives for the evaluation of these bioactive compounds as phytopharmaceutical products. Plant extract act as antimicrobials to prevent and reduce bacterial contaminationBeans of Pterodon emarginatus has antibacterial propertiesExtraction with different solvents might implicate on the rate of bacterial deathThe effect of different microbiological methods (well diffusion, disc diffusion and microdilution) was evaluated on reducing CFUThe results showed by MBC

    Full Text Available Phytotherapies have offered alternative sources of therapy for migraine and gained much importance in prophylactic treatment. Sapindus trifoliatus is a medium-sized deciduous tree growing wild in south India that belongs to the family Sapindaceae. The pericarp is reported for various medicinal properties. A thick aqueous solution of the pericarp is used for the treatment of hemicrania, hysteria or epilepsy in folklore medicine. We have investigated the antihyperalgesic effects of the lyophilized aqueous extract of S. trifoliatus in animal models predictive of experimental migraine models using morphine withdrawal-induced hyperalgesia on the hot-plate test and on 0.3% acetic acid-induced abdominal constrictions in adult male Swiss albino mice. The extract significantly (N = 10, P < 0.05 increased the licking latency in the hot-plate test when administered ip at 10 mg/kg (6.70 ± 0.39 s in saline control vs 18.76 ± 0.96 s in S. trifoliatus-treated animals and significantly (N = 10, P < 0.001 reduced the abdominal constrictions when administered ip at 2 and 10 mg/kg (40.20 ± 1.36 in saline control vs 30.20 ± 1.33 and 23.00 ± 0.98 for 2 and 10 mg/kg, ip, respectively, in S. trifoliatus-treated animals. Furthermore, when administered ip at 20 and 100 mg/kg, the extract significantly (N = 10, P < 0.05 inhibited the apomorphine-induced climbing behavior in mice (climbing duration 15.75 ± 5.0 min for saline control vs 11.4 ± 1.28 and 3.9 ± 1.71 min for 20 and 100 mg/kg, respectively, in S. trifoliatus-treated animals. In receptor radioligand-binding studies, the extract exhibited affinity towards D2 receptors. The findings suggest that dopamine D2 antagonism could be the mechanism involved in the antihyperalgesic activity of the aqueous extract of S. trifoliatus.

    Jayapala Rao, G. V. S.; Prasad, T. N. V. K. V.; Shameer, Syed; Arun, T.; Purnachandra Rao, M.


    Biosynthesis of nanoscale materials has its own advantages over other physical and chemical methods. Using soapnut extract as reducing and stabilizing agent for the synthesis of inorganic nanoscale materials is novel and has not been exploited to its potential so far. Herein, we report for the first time on the effects of sulphur substitution on soapnut extract-mediated synthesis of nanoscale NdFeB (S-NdFeB) permanent magnetic powders (Nd 15%, Fe 77.5%, B 7.5% and S with molar ratios: 0.1, 0.2, 0.3, 0.4, and 0.5). To synthesize, a 10 ml of 10% soapnut extract was added to 90 ml of respective chemical composition and heated to 60 °C for 30 min and aged for 24 h. The dried powder was sintered at 500 °C for 1 h. The characterization of the as-prepared nanoscale S-NdFeB magnetic materials was done using the techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersion spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), dynamic light scattering (DLS for size and zeta potential measurements) and vibrating sample magnetometer (VSM)-hysteresis loop studies. The results revealed that particles were highly stable (with a negative zeta potential of 25.7 mV) with irregular and spherical shape (with measured hydrodynamic diameter 6.7 and 63.5 nm). The tetragonal structures of the formed powders were revealed by XRD micrographs. Hysteresis loop studies clearly indicate the effect of S concentration on the enhanced magnetization of the materials.

    Paolo Agnelli


    Full Text Available Myotis emarginatus (Chiroptera, Vespertilionidae utilizza frequentemente gli edifici come rifugio estivo, sia per il riposo diurno che per la riproduzione. Negli anni 1996-2003, nel corso di indagini faunistiche sul territorio toscano, questa specie è stata rilevata nel 26% dei casi su 76 edifici rurali risultati occupati da pipistrelli e rappresenta ben il 50% degli esemplari rilevati. Il numero di esemplari di M. emarginatus in tali rifugi varia da 1 a 150 animali. Un edificio però può rendersi facilmente indisponibile per modificazioni nell?utilizzo da parte dell?uomo: ma cosa succede agli animali che si trovano improvvisamente senza casa? E quanto si può accrescere annualmente una colonia quando non viene disturbata? Nel 1997 nella Riserva Naturale Provinciale di Ponte a Buriano e Penna (AR, rilevammo una colonia riproduttiva di Myotis emarginatus stimata in circa 60 esemplari. Il rifugio estivo utilizzato fino al 2002 è costituito da una casa disabitata. Confrontando le stime effettuate dal 1997 al 2001 possiamo valutare l?accrescimento numerico della colonia: a partire dai circa 60 animali si è raggiunta la consistenza di 75 esemplari nel 2001, ossia circa il 25% in 5 anni (5% annuo di media. I conteggi sono stati effettuati a vista da almeno 3 persone, da breve distanza e in buona luce, ma poiché in questa specie gli esemplari si appendono alle travi addossandosi uno sopra l?altro, è impossibile effettuare un vero conteggio. Nell?estate 2001 abbiamo condotto una ricerca più accurata sull?utilizzo del rifugio: dai rilievi di un rilevatore di passaggio all?infrarosso e soprattutto dalle riprese di una videocamera, risulta che il numero degli esemplari era stato fortemente sottostimato: gli esemplari erano, infatti, ben 150 (femmine, ossia il doppio di quanto stimato sia pure in condizioni favorevoli. A Giugno (2001 abbiamo registrato la nascita di 101 piccoli, il cui tasso di mortalità prima dell

    Sanchez Buitrago Jose Alejandro; Silva Herrera Luis Jairo


    A silvicultural study of Sapindus saponaria L. was carried out including sexual and asexual propagation tests, provenance test, phenological surveillance, and quantification of fruits production. The sexual propagation test was carried out using five source localities, being the best those seeds from Santa Cruz (Bolivia). The asexual propagation test had a negative result because the cuttings did not root, making it necessary to try different methods for asexual reproduction. The seedlings obtained from the sexual propagation test were used to establish a plantation in Otanche (Boyaca) in order to evaluate growth and mortality. After five months, the highest growth was found in those seeds from Santa Cruz (Bolivia). However, this result was not significant from a statistical point of view. The best results regarding mortality came from the seeds from Viota (Cundinamarca), while those from Palmira (Valle) showed the highest levels of mortality. Fruit production was measured and related to the DBH and the canopy wide. Flowering and fruiting periods as well as the harvest season of the fruits in Viota (Cundinamarca) were established. Some methods for fruit harvesting and planting of the species are proposed.

    Full Text Available The aim of this study was to evaluate the phytotoxic potential of aqueous extract of young leaves of Sapindus saponaria L. (soapberry on the diaspore germination and seedling growth Lactuca sativa L. (lettuce and Allium cepa L. (onion, as well as to determine, by bioassay-guided fractioning, whether the fractionated extracts of those leaves are phytotoxic to Triticum aestivum L. (wheat coleoptiles. The aqueous extract was prepared using 100 g of dried plant material dissolved in 1000 ml of distilled water, resulting in a concentration of 10.0%. Distilled water was added in order to obtain dilutions of 7.5%, 5.0%, and 2.5%. The extraction was carried out with young leaves (in powder form and organic solvents of various polarities. We fractioned the ethyl acetate extract using column chromatography. The phytotoxic potential of the aqueous extract of young leaves S. saponaria varied according to the receiving species and the concentration-dependent inhibitory effect. The ethyl acetate extract, specifically fraction 6 (57-70, had the greatest inhibitory effect on the elongation of wheat coleoptiles, indicating that the compounds responsible for the phytotoxic effect reside within this fraction.

    Full Text Available Candida albicans is an opportunistic human pathogen that is capable of causing superficial and systemic infections in immunocompromised patients. Extracts of Sapindus saponaria have been used as antimicrobial agents against various organisms. In the present study, we used a combination of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS to identify the changes in protein abundance of C. albicans after exposure to the minimal inhibitory concentration (MIC and sub-minimal inhibitory concentration (sub-MIC of the butanolic extract (BUTE of S. saponaria and also to fluconazole. A total of six different proteins with greater than 1.5 fold induction or repression relative to the untreated control cells were identified among the three treatments. In general, proteins/enzymes involved with the glycolysis (GPM1, ENO1, FBA1, amino acid metabolism (ILV5, PDC11 and protein synthesis (ASC1 pathways were detected. In conclusion, our findings reveal antifungal-induced changes in protein abundance of C. albicans. By using the previously identified components of the BUTE of S. saponaria(e.g., saponins and sesquiterpene oligoglycosides, it will be possible to compare the behavior of compounds with unknown mechanisms of action, and this knowledge will help to focus the subsequent biochemical work aimed at defining the effects of these compounds.

    Sapindus saponaria L. of Sapindaceae family is popularly known as soldier soap and is found in Central and South America. A study of such medicinal plants might reveal a more complex diversity of microorganisms as compared to non-medicinal plants, considering their metabolic potential and the chemical communication between their natural microbiota. Rhizosphere is a highly diverse microbial habitat with respect to both the diversity of species and the size of the community. Rhizosphere bacteriome associated with medicinal plant S. saponaria is still poorly known. The objective of this study was to assess the rhizosphere microbiome of the medicinal plant S. saponaria using pyrosequencing, a culture-independent approach that is increasingly being used to estimate the number of bacterial species present in different environments. In their rhizosphere microbiome, 26 phyla were identified from 5089 sequences of 16S rRNA gene, with a predominance of Actinobacteria (33.54%), Acidobacteria (22.62%), and Proteobacteria (24.72%). The rarefaction curve showed a linear increase, with 2660 operational taxonomic units at 3% distance sequence dissimilarity, indicating that the rhizosphere microbiome associated with S. saponaria was highly diverse with groups of bacteria important for soil management, which could be further exploited for agricultural and biotechnological purposes.

    Full Text Available ABSTRACT: In vitro bioassay using Sarcoptes scabiei as a test microorganism is a viable method of study for diverse drugs with acaricidal properties. A great amount of assays proves the diverse and efficient biological activity of extracts and compounds from Brazilian savanna plants. This study had as main object, test and compare the acaricidal activity of four Brazilian Cerrado bioproducts: Stryphnodendron adstringens Mart., Copaifera sp., Lafoensia pacari A. St Hil. and Pterodon emarginatus Vogel, 1837. To perform this test S. scabiei mites were collected from crusts removed on ears of highly infected sows. The mites were selected and separated in Petri dishes with three different concentrations (25, 50 and 75% of each bioproduct, to evaluate their potential acaricidal activity. The mortality of the mites was counted in each Petri dish every hour, during five hours. The statistical analyses demonstrated differences between the bioproducts tested. The oleoresin of Copaifera sp. and P. emarginatus presented the best results with 100% of mites mortality after treatment. The ethanolic extracts of S. adstringens and L. pacari demonstrated lower acaricidal activity when compared to the oleoresins, with little or no difference among the control groups tested. This bioassay demonstrated to be efficient, reliable, low cost and easy accomplishment. Oil resins from Copaifera sp. and P. emarginatus have in vitro acaricidal activity against adult females of S. scabiei var. suis.

    The essential oils (EOs) from the Brazilian species Croton zehntneri, Pterodon emarginatus and Schinopsis brasiliensis were examined for their chemical constituents, and antioxidant and antimicrobial activities. The composition of EOs was determined by using gas chromatography coupled with mass spectrometry analysis, while the antioxidant activity was evaluated through the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and oxygen radical absorbance capacity (ORAC) assays. Furthermore, the antimicrobial activity was investigated against Escherichia coli and Pseudomonas aeruginosa (both Gram-negative), Staphylococcus aureus (Gram-positive) and Candida parapsilosis (fungus). The main components of C. zehntneri, P. emarginatus and S. brasiliensis were identified as estragole, trans-anethole, β-caryophyllene and myrcene. Among the EOs, P. emarginatus showed the highest antioxidant activity, with an IC50 of 7.36 mg/mL and a Trolox equivalent antioxidant capacity of 3748 μmol/g determined by DPPH and ORAC assays, respectively. All EOs showed low activities against the bacterial strains tested, whereas the C. zehntneri oil and its main constituent estragole exhibited an appreciable antifungal activity against C. parapsilosis.

    Flechas, Henry; Arango, Camilo; Morales, Nelly B; Jimenez, Jhon


    This research included the chemical and phyto chemical studies and the industrial scaling in pilot plant of three products of Sapindus saponaria, commonly known as jaboncillo, Michu. This work is part of an interdisciplinary research project aimed at the exploitation and commercialization of its harvested products: oil, gum, and triterpenoidal sapogenins. These three products were obtained through physical and chemical processes both in laboratory (phase 1) and in the industrial scaling stage (phase 2). During the laboratory stage different methods of extraction and purification were studied and assessed, along with the corresponding methods of chemical analysis for the three origins (Palmira, Valle; Viota, Cundinamarca, and Santa Maria, Huila). Based on laboratory studies, extraction and purification processes were designed in a pilot plant supplied by the QUINACOL Ltda. company, whose business is the production, research and development of products for the phyto pharmaceutical industry. Developed products were characterized by methods of instrumental analysis of nuclear magnetic resonance (1H NMR and 13C), flame ionization detector gas chromatography (GC), infrared spectroscopy (IR) and specific chemical analysis techniques designed for these products. The mature fruit of Santa Maria presented increased performance of oil and rubber; as well as the green fruit of Viota, in a substance called Ss1, possibly hederagenina. Of the products obtained in the pilot phase, oil presented a high percentage of unsaturated fatty acids and rubber showed a high thickening capacity in aqueous solutions. Oil and rubber could be marketed from this species' fruit, because its composition and characteristics, as well as its performance, meets the main parameters of marketing, for which studies on industrial perfectibility are needed.

    Full Text Available The objective of this work was to evaluate the allelopathic potential of aqueous extracts of young and mature leaves from Sapindus saponaria on diaspore germination and seedling growth of barnyardgrass (Echinochloa crus-galli and morningglory (Ipomoea grandifolia. The aqueous extract was prepared in a proportion of 100 g of dried, ground leaves dissolved in 1000 mL of distilled water, resulting in a 10% extract concentrate. Dilutions of this concentrate were made with distilled water to 7.5, 5.0 and 2.5%. In seedling growth tests, we compared the effect of these extracts with the herbicide nicosulfuron. Both extracts of mature and young leaves caused delays and reductions in diaspore germination and seedling length of barnyardgrass and morningglory, with the most intense effects observed at a concentration of 10%. The effects of the young leaf extract were more similar to those observed with the herbicide, demonstrating that leaf maturation stage of S. saponaria affects its inhibitory effects on the growth of other plants and that this species is effective in controlling weeds.O objetivo deste trabalho foi avaliar o potencial alelopático do extrato aquoso de folhas jovens e maduras de Sapindus saponaria (sabão-de-soldado na germinação de diásporos e no crescimento de plântulas de capim-arroz (Echinochloa crus-galli e corda-de-viola (Ipomoea grandifolia.

    Full Text Available Methane produced in the rumen system causes the lost of ingested chemical energy, and the methane emitted contributes the greenhouse effect to the atmosphere environment. A study to evaluate the effectiveness of saponin from Sapindus rarak fruit as an inhibitor of ruminal methanogenesis was conducted. The method conducted in this study was a fermentation of a substrate by in vitro technique using rumen fluid (obtained from fistulated sheep as inoculum. Substrate (king grass was fermented in anaerobic incubator system at pH of medium 6.9 and temperature of 39°C for 48 hours. Inoculum was supplemented with an ingredient obtained by extraction of Sapindus rarak fruit with methanol (Aksapon SR and the ones without extraction (lerak powder, and further, these treatments were compared to other methanogenesis inhibitors (i.e. Fe3+, SO4 2– and poly unsaturated longchain fatty acids: PULCFA.The treatments were 1. Inoculum without treatment (K; 2. K + Aksapon SR (80 mg/100 ml; 3. K + lerak powder (160 mg/100 ml; 4. K + Fe3+ (0.8 mg/100 ml; 5. K + SO4 2- (96 mg/100 ml; 6. K + PULCFA (24 mg/100 ml. Measurements conducted were portion of methane, dry matter digestibility (DMD, NH3-N content, microbial population, and volatile fatty acids (VFA. The data measured were analyzed by using completely randomized design. The results of the experiment showed that Aksapon SR was the most effective inhibitor of methanogenesis compared to the others, that is when compared to control, Aksapon SR lowered methane production by 31% (P0.05 and SO4 2–(10% (P>0.05. All additive treatments did not affect the DMD value of the substrate fermented by control inoculum. Compared to control, all treatments lowered the protozoal population where the Aksapon SR gave the strongest effect (1.91 x 105 vs 9.94 x 105 cell/ml, and the decrease of protozoal number in Aksapon SR treatment was followed by the increase of bacterial (4.13 x 109 vs 2.56 x 109 colony/ml.

    Full Text Available Abstract Background The aim of the present work was to evaluate the effect of a hexane crude extract (HCE of Pterodon emarginatus on the oxidative and nitrosative stress induced in skeletal muscle, liver and brain of acutely exercised rats. Methods Adult male rats were subjected to acute exercise by standardized contractions of the tibialis anterior (TA muscle (100 Hz, 15 min and treated orally with the HCE (once or three times with a fixed dose of 498 mg/kg, before and after acute exercise. Serum creatine kinase activity was determined by a kinetic method and macrophage infiltration by histological analyses of TA muscle. Lipid peroxidation was measured as malondialdehyde (MDA levels. Nitric oxide production was evaluated by measuring nitrite formation, using Griess reagent, and nitrotyrosine was assessed by western blotting. Results Serum creatine kinase activities in the controls (111 U/L increased 1 h after acute exercise (443 U/L. Acute exercise also increased the infiltration of macrophages into TA muscle; lipid peroxidation levels in TA muscle (967%, liver (55.5% and brain (108.9%, as well as the nitrite levels by 90.5%, 30.7% and 60%, respectively. The pattern of nitrotyrosine formation was also affected by acute exercise. Treatment with HCE decreased macrophage infiltration, lipid peroxidation, nitrite production and nitrotyrosine levels to control values. Conclusion Acute exercise induced by functional electrical stimulation in rats resulted in increase in lipid peroxidation, nitrite and nitrotyrosine levels in brain, liver and skeletal muscle. The exercise protocol, that involved eccentric muscle contraction, also caused some muscle trauma, associated with over-exertion, leading to inflammation. The extract of P. emarginatus abolished most of these oxidative processes, thus confirming the high antioxidant activity of this oil which infusions are used in folk medicine against inflammatory processes.

    Full Text Available The problem with low meat production is caused by several factors, ie: management, feed and animal health. The development of integration system such as cattle-rice, cattle-corn and cattle-palm oil aims to utilize feed from local resources. However, sometimes local feedstuff causes a problem of imbalance nutrient. There are several strategies to overcome this problem and one of them is the use of feed additives from natural substance or plant resources such as lerak (Sapindus rarak De Candole. This research was aimed to utilize lerak fruit to improve performance and evaluate some blood profiles of Ongole crossbred cattle. The in vivo work was done using 12 Ongole crossbred cattle receiving 3 different feeds as treatment, i.e. 1 feed without lerak (high roughage diet as control, 2 feed contained 2,5% lerak, and 3 feed contained 5% lerak. Growth, daily gain, blood profiles (leucocytes, cholesterol, trigliceride and globulins were observed. The results showed no significant differences for nutrient intake, meaning that the ration has good palatability. Average daily gain of cattle fed with 2,5% lerak was 20% higher than those with control diet. White blood cells tended to decrease caused by lerak treatments, but the globulin profiles (alpha, beta and gamma were not significantly affected in all treatments. Blood cholesterol concentration decreased following the increase of lerak percentage. It is not recommended to use lerak in the cattle ration for more than two months because of the decreasing of leucocytes.

    Fu, Yong; Lei, Peng; Han, Yu-mei; Yan, Dan


    To study the technological parameters of the purification process of saponins with macroporous adsorption resin. The adsorptive characteristics and elutive parameters of the process were studied by taking the elutive and purified ratio of saponins as markers. Bacteriostasis activity of each parts eluted was evaluated by the mean of cup-plate method. 13.6 mL of the extraction of sapindus saponin (crude drugs 0.01 g/mL) was purified with a column of macroporous adsorption resin (phi15 mm x H90 mm, dry weight 2.5 g) and washed with 3BV of distilled water, then eluted with 3BV of 30% ethanol and 3BV of 70% ethanol, most of saponins were collected in the 70% ethanol. With macroporous adsorption resin adsorbing and purifying, the elutive ratio of saponins was 93.8% and the purity reached 250.1%. So this process of applying macroporous adsorption resin to adsorb and purify saponins is feasible, and supplies reference to the purification of other types of saponin.

    Seed priming with plant extracts and chemicals has been used as an important growth enhancement tool in crop plants. In this research, an attempt was made to understand the mechanism of various seed priming treatments on greenhouse-grown okra (Abelmoschus esculentus (L.) Moench.), sunflower (Helianthus annuus L.), peanut (Arachis hypogaea L.) and chickpea (Cicer arietinum L.) for the control of root infecting fungi like Rhizoctonia solani (Kn), Fusarium spp. and Macrophomina phaseolina (Tassi) Goid by plant parts extracts (stem, leaves and seeds) of Acacia nilotica (L.) Willd. ex Delile and Sapindus mukorossi (L) at different time intervals (5, 10, 20, 40 minutes). Results showed significant suppression of root rot fungi and significantly enhanced the growth parameters like shoot length, root length, shoot weight and root weight. Seed-priming with A. nilotica and S. mukorossi leaves extract for 10 minutes time interval was found to be effective for the control of root rot fungi and growth of all tested leguminous and non-leguminous plants.

  4. Non-Edible Plant Oils as New Sources for Biodiesel Production

    Directory of Open Access Journals (Sweden)

    M. Rafiqul Islam


    Full Text Available Due to the concern on the availability of recoverable fossil fuel reserves and the environmental problems caused by the use those fossil fuels, considerable attention has been given to biodiesel production as an alternative to petrodiesel. However, as the biodiesel is produced from vegetable oils and animal fats, there are concerns that biodiesel feedstock may compete with food supply in the long-term. Hence, the recent focus is to find oil bearing plants that produce non-edible oils as the feedstock for biodiesel production. In this paper, two plant species, soapnut (Sapindus mukorossi and jatropha (jatropha curcas, L. are discussed as newer sources of oil for biodiesel production. Experimental analysis showed that both oils have great potential to be used as feedstock for biodiesel production. Fatty acid methyl ester (FAME from cold pressed soapnut seed oil was envisaged as biodiesel source for the first time. Soapnut oil was found to have average of 9.1% free FA, 84.43% triglycerides, 4.88% sterol and 1.59% others. Jatropha oil contains approximately 14% free FA, approximately 5% higher than soapnut oil. Soapnut oil biodiesel contains approximately 85% unsaturated FA while jatropha oil biodiesel was found to have approximately 80% unsaturated FA. Oleic acid was found to be the dominant FA in both soapnut and jatropha biodiesel. Over 97% conversion to FAME was achieved for both soapnut and jatropha oil.

    Full Text Available Crocidolomia pavonana is an important pest of Brassicaceous vegetable crops. Botanical insecticides are potential alternatives for the control of C. pavonana pest. Insecticidal activity of Piper aduncum and Sapindus rarak fruit extracts as well as their mixtures was evaluated against C. pavonana larvae in the laboratory. Ethyl acetate P. aduncum (EtPa extract as well as methanolic S. rarak (MeSr and aqueous S. rarak (AqSr extracts were tested separately and in mixtures against second-instar larvae C. pavonana by a leaf-residue feeding method. At the LC95 level - 72 hours after treatment (HAT, EtPa extract was about 14.5 and 12.8 times, respectively, more toxic to C. pavonana larvae than MeSr and AqSr extracts. At the LC95 level, EtPa + MeSr extract mixture (1 : 10 w/w was about 1.64 times more toxic to the test larvae than EtPa + AqSr extract mixture (1 : 10 w/w. Based on combination index at 48, 72, and 96 HAT, EtPa + MeSr extract mixture at LC50 level as well as EtPa + AqSr extract mixture at LC50 and LC95 levels had additive joint action, whereas EtPa + MeSr extract mixture at LC95 was weakly synergistic. In addition to lethal effect, the treatment with all test materials delayed the development of C. pavonana larvae from second-instar to fourth instar. Thus, EtPa, MeSr, and AqSr extracts as well as the mixtures between EtPa and S. rarak extracts are potential alternatives for the control of C. pavonana pest.

  13. Enhanced removal of lead from contaminated soil by polyol-based deep eutectic solvents and saponin (United States)

    Mukhopadhyay, Soumyadeep; Mukherjee, Sumona; Hayyan, Adeeb; Hayyan, Maan; Hashim, Mohd Ali; Sen Gupta, Bhaskar


    Deep eutectic solvents (DESs) are a class of green solvents analogous to ionic liquids, but less costly and easier to prepare. The objective of this study is to remove lead (Pb) from a contaminated soil by using polyol based DESs mixed with a natural surfactant saponin for the first time. The DESs used in this study were prepared by mixing a quaternary ammonium salt choline chloride with polyols e.g. glycerol and ethylene glycol. A natural surfactant saponin obtained from soapnut fruit pericarp, was mixed with DESs to boost their efficiency. The DESs on their own did not perform satisfactory due to higher pH; however, they improved the performance of soapnut by up to 100%. Pb removal from contaminated soil using mixture of 40% DES-Gly and 1% saponin and mixture of 10% DES-Gly and 2% saponin were above 72% XRD and SEM studies did not detect any major corrosion in the soil texture. The environmental friendliness of both DESs and saponin and their affordable costs merit thorough investigation of their potential as soil washing agents.

    Dufkova, Lucie; Straková, Petra; Širmarová, Jana; Salát, Jiří; Moutelíková, Romana; Chrudimský, Tomáš; Bartonička, Tomáš; Nowotny, Norbert; Růžek, Daniel


    Astroviruses are a major cause of gastroenteritis in humans and animals. Recently, novel groups of astroviruses were identified in apparently healthy insectivorous bats. We report the detection of diverse novel astrovirus sequences in nine different European bat species: Eptesicus serotinus, Hypsugo savii, Myotis emarginatus, M. mystacinus, Nyctalus noctula, Pipistrellus nathusii or P. pygmaeus, P. pipistrellus, Vespertilio murinus, and Rhinolophus hipposideros. In six bat species, astrovirus sequences were detected for the first time. One astrovirus strain detected in R. hipposideros clustered phylogenetically with Chinese astrovirus strains originating from bats of the families Rhinolophidae and Hipposideridae. All other Czech astrovirus sequences from vesper bats formed, together with one Hungarian sequence, a separate monophyletic lineage within the bat astrovirus group. These findings provide new insights into the molecular epidemiology, ecology, and prevalence of astroviruses in European bat populations.

    Rachel R. P. Machado


    Full Text Available It is demonstrated that the efficiency of antibiotics can be tested using an interferometric method. Two antibiotics were used as models to show that an interferometric method to monitor the metabolic activity of slowly growing bacteria can be a safer method to judge antimicrobial properties of substances than conventional methods. The susceptibility of Mycobacterium bovis to hexane extract of Pterodon emarginatus and to the well-known antibiotic rifampicin was tested with the interferometric method and with the conventional microplate method. The microplate method revealed a potential activity of hexane extract against M. bovis. However, the interferometric method showed that the action of this substance is rather limited. Also in the case of rifampicin, the interferometric method was able to detect resistant bacteria.

    Lisiane Bajerski

    Full Text Available ABSTRACT Vegetable oils present important pharmacological properties, which gained ground in the pharmaceutical field. Its encapsulation in nanoemulsions is considered a promising strategy to facilitate the applicability of these natural compounds and to potentiate the actions. These formulations offer several advantages for topical and systemic delivery of cosmetic and pharmaceutical agents including controlled droplet size, protection of the vegetable oil to photo, thermal and volatilization instability and ability to dissolve and stabilize lipophilic drugs. For these reasons, the aim of this review is to report on some characteristics, preparation methods, applications and especially analyze recent research available in the literature concerning the use of vegetable oils with therapeutic characteristics as lipid core in nanoemulsions, specially from Brazilian flora, such as babassu (Orbignya oleifera, aroeira (Schinus molle L., andiroba (Carapa guaianiensis, casca-de-anta (Drimys brasiliensis Miers, sucupira (Pterodon emarginatus Vogel and carqueja doce (Stenachaenium megapotamicum oils.

    Full Text Available Se evaluó la capacidad de extractos orgánicos de 48 especies de plantas costarricenses para neutralizar la actividad hemorrágica del veneno de la serpiente Bothrops asper (terciopelo. Los extractos se evaluaron mediante un bioensayo basado en inyecciones intradérmicas de veneno en ratones, o de mezclas veneno-extracto, seguidas de la cuantificación macroscópica de la hemorragia. Se observó una inhibición total de la hemorragia con los extractos etanólico, de acetato de etilo y acuoso de Bursera simaruba, Clusia torresii, C. palmana, Croton draco, Persea americana, Phoebe brenesii, Pimenta dioica, Sapindus saponaria, Smilax cuculmeca y Virola koschnyi. El análisis químico de estos extractos permitió identificar catequinas, flavonas, antocianinas y taninos condensados, los cuales podrían jugar un papel en la inhibición del efecto hemorrágico debido a la capacidad de quelar el ion zinc requerido por las metaloproteinasas hemorrágicas para su acción.Organic extracts representing 48 species included in 30 families of Costa Rican tropical plants were evaluated for their ability to neutralize hemorrhagic activity induced by the venom of the snake Bothrops asper. A bioassay in mice was used, based on intradermal injection of either venom or venom-extract mixtures followed by the measurement of hemorrhagic areas. Total inhibition of hemorrhage was observed with the ethanolic, ethyl acetate and aquous extracts of Bursera simaruba, Clusia torresii, C. palmana, Croton draco, Persea americana, Phoebe brenesii, Pimenta dioica, Sapindus saponaria, Smilax cuculmeca and Virola koschnyi. Chemical analysis of these extracts identified catequines, flavones, anthocyanines and condensated tannins, which may be responsible for the inhibitory effect observed, probably owing to the chelation of the zinc required for the catalytic activity of venom’s hemorrhagic metalloproteinases.

    Full Text Available The Arene Candide Cave (Finale Ligure, Northern Italy is considered one of the most important prehistoric site in Italy. The archaeological excavations conducted by the “Istituto Italiano di Paleontologia Umana” of Rome revealed 3 different horizons: an upper horizon with Holocene human presence dated from the Neolithic to the Byzantine period, and two underlying Pleistocene horizons with Gravettian and Epigravettian lithic artefacts. The stratigraphical sequence of the upper Palaeolithic is divided in two groups of strata separated by a depositional gap: the “P” complex, divided in 13 layers, dated from 25,620 to 18,560 years BP, and the 5 “M” layers dated between 11,750 and 9,980 years BP (14C non-calibrated dating.In this paper the fossil bone remains of bats from “M” layers are described. Fifteen taxa, divided into 3 families and 6 genera have been identified: Rhinolophus ferrumequinum, R. mehelyi, R. euryale, R. hipposideros, Myotis myotis, M. blythii, M. capaccinii, M. emarginatus, M. mystacinus s.l., Myotis sp.

  6. White-nose syndrome fungus: a generalist pathogen of hibernating bats.

    Directory of Open Access Journals (Sweden)

    Jan Zukal

    Full Text Available Host traits and phylogeny can determine infection risk by driving pathogen transmission and its ability to infect new hosts. Predicting such risks is critical when designing disease mitigation strategies, and especially as regards wildlife, where intensive management is often advocated or prevented by economic and/or practical reasons. We investigated Pseudogymnoascus [Geomyces] destructans infection, the cause of white-nose syndrome (WNS, in relation to chiropteran ecology, behaviour and phylogenetics. While this fungus has caused devastating declines in North American bat populations, there have been no apparent population changes attributable to the disease in Europe. We screened 276 bats of 15 species from hibernacula in the Czech Republic over 2012 and 2013, and provided histopathological evidence for 11 European species positive for WNS. With the exception of Myotis myotis, the other ten species are all new reports for WNS in Europe. Of these, M. emarginatus, Eptesicus nilssonii, Rhinolophus hipposideros, Barbastella barbastellus and Plecotus auritus are new to the list of P. destructans-infected bat species. While the infected species are all statistically phylogenetically related, WNS affects bats from two suborders. These are ecologically diverse and adopt a wide range of hibernating strategies. Occurrence of WNS in distantly related bat species with diverse ecology suggests that the pathogen may be a generalist and that all bats hibernating within the distribution range of P. destructans may be at risk of infection.

    Host traits and phylogeny can determine infection risk by driving pathogen transmission and its ability to infect new hosts. Predicting such risks is critical when designing disease mitigation strategies, and especially as regards wildlife, where intensive management is often advocated or prevented by economic and/or practical reasons. We investigated Pseudogymnoascus [Geomyces] destructans infection, the cause of white-nose syndrome (WNS), in relation to chiropteran ecology, behaviour and phylogenetics. While this fungus has caused devastating declines in North American bat populations, there have been no apparent population changes attributable to the disease in Europe. We screened 276 bats of 15 species from hibernacula in the Czech Republic over 2012 and 2013, and provided histopathological evidence for 11 European species positive for WNS. With the exception of Myotis myotis, the other ten species are all new reports for WNS in Europe. Of these, M. emarginatus, Eptesicus nilssonii, Rhinolophus hipposideros, Barbastella barbastellus and Plecotus auritus are new to the list of P. destructans-infected bat species. While the infected species are all statistically phylogenetically related, WNS affects bats from two suborders. These are ecologically diverse and adopt a wide range of hibernating strategies. Occurrence of WNS in distantly related bat species with diverse ecology suggests that the pathogen may be a generalist and that all bats hibernating within the distribution range of P. destructans may be at risk of infection.

    Manuel Calvopiña


    Full Text Available A review of national and international publications on paragonimiasis in Ecuador, epidemiological records from the Ministry of Public Health and unpublished research data was conducted to summarise the current status of the parasite/disease. The purpose of the review is to educate physicians, policy-makers and health providers on the status of the disease and to stimulate scientific investigators to conduct further research. Paragonimiasis was first diagnosed in Ecuador 94 years ago and it is endemic to both tropical and subtropical regions in 19 of 24 provinces in the Pacific Coast and Amazon regions. Paragonimus mexicanus is the only known species in the country, with the mollusc Aroapyrgus colombiensis and the crabs Moreirocarcinus emarginatus, Hypolobocera chilensis and Hypolobocera aequatorialis being the primary and secondary intermediate hosts, respectively. Recent studies found P. mexicanus metacercariae in Trichodactylus faxoni crabs of the northern Amazon. Chronic pulmonary paragonimiasis is commonly misdiagnosed and treated as tuberculosis and although studies have demonstrated the efficacy of praziquantel and triclabendazole for the treatment of human infections, neither drug is available in Ecuador. Official data recorded from 1978-2007 indicate an annual incidence of 85.5 cases throughout the 19 provinces, with an estimated 17.2% of the population at risk of infection. There are no current data on the incidence/prevalence of infection, nor is there a national control programme.

    Azrina Azlan


    Full Text Available Fruit pods contain various beneficial compounds that have biological activities and can be used as a source of pharmaceutical and nutraceutical products. Although pods or pericarps are usually discarded when consuming the edible parts of fruits, they contain some compounds that exhibit biological activities after extraction. Most fruit pods included in this review contain polyphenolic components that can promote antioxidant effects on human health. Additionally, anti-inflammatory, antibacterial, antifungal and chemopreventive effects are associated with these fruit pod extracts. Besides polyphenolics, other compounds such as xanthones, carotenoids and saponins also exhibit health effects and can be potential sources of nutraceutical and pharmaceutical components. In this review, information on fruit pods or pericarp of Garcinia mangostana, Ceratonia siliqua, Moringa oleifera, Acacia nilotica, Sapindus rarak and Prosopis cineraria is presented and discussed with regard to their biological activity of the major compounds existing in them. The fruit pods of other ethno- botanical plants have also been reviewed. It can be concluded that although fruit pods are considered as being of no practical use and are often being thrown away, they nevertheless contain compounds that might be useful sources of nutraceutical and other pharmaceutical components.

  12. Application of saponin biosurfactant and its recovery in the MEUF process for removal of methyl violet from wastewater. (United States)

    Samal, Kulbhushan; Das, Chandan; Mohanty, Kaustubha


    The potential of saponin, a biosurfactant, in the micellar enhanced ultrafiltration (MEUF) process was tested systematically for removal of methyl violet from wastewater. For this, the aqueous extract of reetha (Sapindus mukorossi) pericarp which contains saponin was used as the biosurfactant. First, the micellar solubilization of methyl violet in saponin micelles was investigated in terms of molar solubilization power (SP) of saponin. It was observed that the adsorption of methyl violet on the agglomerates of saponin micelles was mainly responsible for the enhanced solubilization. The Gibbs free energy of solubilization (calculated as -29.63 kJ mol -1 ) suggested that process was feasible and spontaneous. The MEUF experiments were performed in batch as well as continuous mode using saponin biosurfactant, and the effect of operating parameters on permeate flux and solute retention were evaluated. The removal of methyl violet in MEUF process was >99% achieved with 10 kDa polyethersulfone (PES) membrane for feed dye concentration of 250 mg L -1 at studied conditions. Finally, the saponin in permeate was recovered using n-heptane and n-butanol by solvent extraction process. The solvent n-butanol showed better extraction efficiency as compared to n-heptane for saponin extraction. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Chen, Yu-Fen; Yang, Chao-Hsun; Chang, Ming-Shiang; Ciou, Yong-Ping; Huang, Yu-Chun


    The defatted seed meal of Camellia oleifera has been used as a natural detergent and its extract is commercially utilized as a foam-stabilizing and emulsifying agent. The goal of this study was to investigate the foam properties and detergent ability of the saponins from the defatted seed meal of C. oleifera. The crude saponin content in the defatted seed meal of C. oleifera was 8.34 and the total saponins content in the crude saponins extract was 39.5% (w/w). The foaming power of the 0.5 crude saponins extract solution from defatted seed meal of C. oleifera was 37.1 of 0.5 SLS solution and 51.3% to that of 0.5% Tween 80 solution. The R5 value of 86.0% represents good foam stability of the crude saponins extracted from the defatted seed meal of the plant. With the reduction of water surface tension from 72 mN/m to 50.0 mN/m, the 0.5% crude saponins extract solution has wetting ability. The sebum-removal experiment indicated that the crude saponins extract has moderate detergency. The detergent abilities of the saponins from C. oleifera and Sapindus mukorossi were also compared.

  14. The Effects of Climate Change on the Development of Tree Plantations for Biodiesel Production in China

    Directory of Open Access Journals (Sweden)

    Guanghui Dai


    Full Text Available Biodiesel produced from woody oil plants is a promising form of renewable energy but a combination of tree plantations’ long cultivation time and rapid climate change may put large-scale production at risk. If plantations are located in future-unsuitable places, plantations may fail or yield may be poor, then significant financial, labor, and land resources invested in planting programs will be wasted. Incorporating climate change information into the planning and management of forest-based biodiesel production therefore can increase its chances of success. However, species distribution models, the main tool used to predict the influence of future climate–species distribution modeling, often contain considerable uncertainties. In this study we evaluated how these uncertainties could affect the assessment of climate suitability of the long-term development plans for forest-based biodiesel in China by using Sapindus mukorossi Gaertn as an example. The results showed that only between 59% and 75% of the planned growing areas were projected suitable habitats for the species, depending on the set-up of simulation. Our results showed the necessity for explicitly addressing the uncertainty of species distribution modeling when using it to inform forest-based bioenergy planning. We also recommend the growing area specified in China’s national development plan be modified to lower the risk associated with climate change.

    Khaloud Al Badi


    Full Text Available The study aimed to formulate a pure herbal shampoo and to evaluate and compare its physicochemical properties with the marketed synthetic and herbal shampoos. The herbal shampoo was formulated by adding the extracts of Acacia concinna, Sapindus mukorossi, Phyllanthus emblica, Ziziphus spina-christi and Citrus aurantifolia in different proportions to a 10% aqueous gelatin solution. Small amount of methyl paraben was added as a preservative and pH was adjusted with citric acid. Several tests such as visual inspection, pH, wetting time, % of solid contents, foam volume and stability, surface tension, detergency, dirt dispersion etc, were performed to determine the physicochemical properties of both prepared and marketed shampoos. The formulated herbal shampoo was also evaluated for conditioning performance by administering a blind test to 20 student volunteers. The formulated herbal shampoo was clear and appealing. It showed good cleansing and detergency, low surface tension, small bubble size and good foam stability after 5 min. The prepared shampoo and commercial shampoos showed comparable results for % solid contents also. The score of the conditioning performance of the tress washed with herbal shampoo was found to be 3.0 out of 4, while the score of the marketed synthetic and herbal shampoo was 3.4 and 3.3 respectively. The results indicated the formulated shampoo is having excellent conditioning performance, at par with commercially available shampoo. However, further research and development is required to improve it's quality and safety.

    Delgado, Denia Caridad; Galindo, Juana; González, Rogelio; González, Niurca; Scull, Idania; Dihigo, Luís; Cairo, Juan; Aldama, Ana Irma; Moreira, Onidia


    The aim of this paper was to present the main results obtained in Cuba on the effects of feeding tropical trees and shrubs on rumen methanogenesis in animals fed with low quality fibrous diets. More than 20 tree and shrub foliages were screened for phytochemicals and analyzed for chemical constituents. From these samples, seven promising plants (Samanea saman, Albizia lebbeck, Tithonia diversifolia, Leucaena leucocephala, Trichantera gigantea, Sapindus saponaria, and Morus alba) were evaluated for methane reduction using an in vitro rumen fermentation system. Results indicated that the inclusion levels of 25% of Sapindo, Morus, or Trichantera foliages in the foliages/grass mixtures (grass being Pennisetum purpureum) reduced (P lebbeck, or T. diversifolia accession 23 foliages when mixed at the rate of 30% in Cynodon nlemfuensis grass produced lower methane compared to the grass alone. Inclusion levels of 15% and 25% of a ruminal activator supplement containing 29% of L. leucocehala foliage meal reduced methane by 37% and 42% when compared to the treatment without supplementation. In vivo experiment with sheep showed that inclusion of 27% of L. leucocephala in the diet increased the DM intake but did not show significant difference in methane production compared to control diet without this foliage. The results of these experiments suggest that the feeding of tropical tree and shrub foliages could be an attractive strategy for reduction of ruminal methanogenesis from animals fed with low-quality forage diets and for improving their productivity.

  17. Development of a New Type of Green Switch Air Entraining Agent for Wet-Mix Shotcrete and Its Engineering Application

    Guoming Liu


    Full Text Available Air entraining agent (AEA can bring a lot of microbubbles into fresh concrete for improving its fluidity; however, high fluidity has adverse effect on the shootability of wet-mix shotcrete. In order to solve the contradictory issue, the paper developed a new type of green switch air entraining agent (GSAE that can improve both the pumpability and shootability. The single-admixture and combination tests containing foaming ability and surface tension were performed with Deer agitator and automatic tension meter. The new AEA was developed with two constituents A and B. A was prepared with Sapindus mukorossi(S-1, dodecyl trimethyl ammonium chloride(1231, and polyacrylamide. B was prepared with lauryl sodium sulfate (K12 and silicone oil. The mass mix proportion was S-1 : 1231 : polyacrylamide : K12 : silicone oil = 1 : 0.33 : 0.2 : 0.33 : 0.47. The application method of GSAE proposed that A was premixed with fresh concrete and then B was added at nozzle. Experimental investigation showed that the optimal mixing amount of GSAE was 0.1%–0.2% relative to cement. All performance measured of wet-mix shotcrete with 0.12% GSAE met the first-grade product requirements of the China National Standard. Compared with the conventional type of AEA, the proposed GSAE is capable of effectively improving pumpability and shootability.

  18. Pseudogymnoascus destructans: evidence of virulent skin invasion for bats under natural conditions, Europe. (United States)

    Bandouchova, H; Bartonicka, T; Berkova, H; Brichta, J; Cerny, J; Kovacova, V; Kolarik, M; Köllner, B; Kulich, P; Martínková, N; Rehak, Z; Turner, G G; Zukal, J; Pikula, J


    While Pseudogymnoascus destructans has been responsible for mass bat mortalities from white-nose syndrome (WNS) in North America, its virulence in Europe has been questioned. To shed the light on the issue of host-pathogen interaction between European bats and P. destructans, we examined seventeen bats emerging from the fungus-positive underground hibernacula in the Czech Republic during early spring 2013. Dual wing-membrane biopsies were taken from Barbastella barbastellus (1), Myotis daubentonii (1), Myotis emarginatus (1), Myotis myotis (11), Myotis nattereri (1) and Plecotus auritus (2) for standard histopathology and transmission electron microscopy. Non-lethal collection of suspected WNS lesions was guided by trans-illumination of the wing membranes with ultraviolet light. All bats selected for the present study were PCR-positive for P. destructans and showed microscopic findings consistent with the histopathological criteria for WNS diagnosis. Ultramicroscopy revealed oedema of the connective tissue and derangement of the fibroblasts and elastic fibres associated with skin invasion by P. destructans. Extensive fungal infection induced a marked inflammatory infiltration by neutrophils at the interface between the damaged part of the wing membrane replaced by the fungus and membrane tissue not yet invaded by the pathogen. There was no sign of keratinolytic activity in the stratum corneum. Here, we show that lesions pathognomonic for WNS are common in European bats and may also include overwhelming full-thickness fungal growth through the wing membrane equal in severity to reports from North America. Inter-continental differences in the outcome of WNS in bats in terms of morbidity/mortality may therefore not be due to differences in the pathogen itself. © 2014 Blackwell Verlag GmbH.

  2. The Use of Plant Bioactive Compounds to Mitigate Enteric Methane in Ruminants and its Application in Indonesia

    Directory of Open Access Journals (Sweden)

    Elizabeth Wina


    Full Text Available Worldwide, increasing greenhouse gas (GHG emissions have become a major concern as they are now considered to be the cause of global warming. Several strategies have been planned and taken by different countries including Indonesia to mitigate this situation. Agriculture is considered to be one of major contributors to GHG, especially methane coming from ruminant digestive processes. More than 85% of the methane produced by ruminants comes from enteric fermentation. Several options have been proposed to lower this enteric methane production. This paper describes a review on diet manipulation using feed additives, especially plant bioactive compounds, to mitigate the GHG emission from ruminant livestock. Plant bioactive compounds have been found with various chemical structures. Some of them such as saponin, tannin, essential oils, organosulphur compounds, have been reported to have ability to reduce enteric methane production. Indonesia has many plant resources that have potential as methane reducing agents. Sapindus rarak fruit especially its methanol extract contain saponins which reduce the activity of methanogens in the rumen in vitro, hence reduce methane production (11%. Feeding S. rarak to sheep increased daily weight gain but not that of local cattle. Shrub legumes such as Calliandra calothyrsus and Leucaena leucocephala contain tannins which can reduce methanogenesis (3 – 21% methane reduction. Besides tannin, these shrub legumes are a good source of protein. Feeding shrub legumes can be beneficial as a protein source and a methane reducer. Other sources of methane reducing agents have been tested in other countries and some can be applied for Indonesian situation. The strategy to reduce methane by plant bioactive compounds should be developed to be simple and relatively cheap so it will benefit the local farmers. Extraction of these compounds may be expensive, therefore, costs should be considered carefully when proposing to use the

  3. Miocene fossil plants from Bukpyeong Formation of Bukpyeong Basin in Donghae City, Gangwon-do Province, Korea and their palaeoenvironmental implications (United States)

    Jeong, Eun Kyoung; Kim, Hyun Joo; Uemura, Kazuhiko; Kim, Kyungsik


    The Tertiary sedimentary basins are distributed along the eastern coast of Korean Peninsula. The northernmost Bukpyeong Basin is located in Donghae City, Gangwon-do Province, Korea. The Bukpyeong Basin consists of Bukpyeong Formation and Dogyeongri Conglomerate in ascending order. The geologic age of Bukpyeong Formation has been suggested as from Early Miocene to Pliocene, In particular, Lee & Jacobs (2010) suggested the age of the Bukpyeong Formation as late Early Miocene to early Middle Miocene based on the fossils of rodent teeth. Sedimentary environment has been thought as mainly fresh water lake and/or swamp partly influenced by marine water. Lately, new outcrops of Bukpyeong Formation were exposed during the road construction and abundant fossil plants were yielded from the newly exposed outcrops. As a result of palaeobotanical studies 47 genera of 23 families have been found. This fossil plant assemblage is composed of gymnosperms and dicotyledons. Gymnosperms were Pinaceae (e.g., Pinus, Tsuga), Sciadopityaceae (e.g., Sciadopitys) and Cupressaceae with well-preserved Metasequoia cones. Dicotyledons were deciduous trees such as Betulaceae (e.g., Alnus, Carpinus) and Sapindaceae (e.g., Acer, Aesculus, Sapindus), and evergreen trees such as evergreen Fagaceae (e.g., Castanopsis, Cyclobalanopsis, Pasania) and Lauraceae (e.g., Cinnamomum, Machilus). In addition, fresh water plants such as Hemitrapa (Lytraceae) and Ceratophyllum (Ceratophyllaceae) were also found. The fossil plant assemblage of the Bukpyeong Formation supported the freshwater environment implied by previous studies. It can be suggested that the palaeoflora of Bukpyeong Formation was oak-laurel forest with broad-leaved evergreen and deciduous trees accompanying commonly by conifers of Pinaceae and Cupressaceae under warm-temperate climate.

  5. Medicinal plants, traditional medicine, markets and management in far-west Nepal. (United States)

    Kunwar, Ripu M; Mahat, Laxmi; Acharya, Ram P; Bussmann, Rainer W


    Modern therapeutic medicine is historically based on indigenous therapies and ethnopharmacological uses, which have become recognized tools in the search for new sources of pharmaceuticals. Globalization of herbal medicine along with uncontrolled exploitative practices and lack of concerted conservation efforts, have pushed many of Nepal's medicinal plants to the verge of extinction. Sustainable utilization and management of medicinal plants, based on traditional knowledge, is therefore necessary. After establishing verbal informed consent with participating communities, five field surveys, roughly 20 days in duration, were carried out. In all, 176 schedules were surveyed, and 52 participants were consulted through focus group discussions and informal meetings. Altogether, 24 key informants were surveyed to verify and validate the data. A total of 252 individuals, representing non-timber forest product (NTFP) collectors, cultivators, traders, traditional healers (Baidhya), community members, etc. participated in study. Medicinal plants were free-listed and their vernacular names and folk uses were collected, recorded, and applied to assess agreement among respondents about traditional medicines, markets and management. Within the study area, medicinal herbs were the main ingredients of traditional therapies, and they were considered a main lifeline and frequently were the first choice. About 55% plants were ethnomedicinal, and about 37% of ethnomedicinal plants possessed the highest informant consensus value (0.86-1.00). Use of Cordyceps sinensis as an aphrodisiac, Berberis asiatica for eye problems, Bergenia ciliata for disintegration of calculi, Sapindus mukorossi for dandruff, and Zanthoxylum armatum for toothache were the most frequently mentioned. These species possess potential for pharmacology. Medicinal plants are inseparable from local livelihoods because they have long been collected, consumed, and managed through local customs and knowledge. Management

    A gas syringe method was used to evaluate the effect of secondary compounds from plant materials on in vitro fermentation products and microbial biomass. The experiment used Pennisetum purpureum, Morinda citrifolia fruit, Nothopanax scutellarium leaves, Sesbania sesban LS (low saponins type), Sesbania sesban HS (high saponins type) and Sapindus rarak fruit as substrates. The incubation was conducted with and without polyethylene glycol 6000 (PEG) addition for 24 hours. Gas production and short-chain fatty acids (SCFA) were analysed. Prokaryotic and eukaryotic concentrations were measured by quantifying 16S and 18S rRNA. The percentage increase in gas production due to PEG was very small (<5%) for all plant materials, which indicated that the biological effect of tannin in these plant materials is limited. TLC analysis revealed that all materials contained saponin, but only S. rarak, followed by S. sesban, contained a high diversity of saponins. S. sesban gave the highest (234 ml/g) while S. rarak gave the lowest gas production (115 ml/g). S. rarak gave the lowest SCFA production (3.57 mmole/g) and also the lowest ratio of acetate to propionate (1.76), indicating a change in pattern of SCFA production. Total elimination of eukaryotic concentration was evident from the absence of the 18S rRNA band when S. rarak and S. sesban were used as sole substrates. S. rarak also reduced the prokaryotic concentration. To use S. rarak as a defaunating agent without affecting prokaryotes, a crude saponin extract was prepared from S. rarak for further experiment. Different concentrations of crude saponins in a methanol extract of S. rarak fruit dissolved in rumen buffer were added to a substrate consisting of elephant grass and wheat bran (7:3 w/w). Microbial biomass yield was quantified by gravimetry and using rRNA as a marker. Addition of crude saponin extract from S. rarak to a high-roughage diet increased microbial biomass (MB) yield to 1.07 and 1.14 times MB yield of the

    Full Text Available Este trabalho foi realizado na mata ciliar do riacho do Navio, Floresta (8º35' 60"S; 38º34'05"W, PE e teve dois objetivos: (a estimar o valor de uso de espécies lenhosas consideradas úteis por moradores do local e (b relacionar o valor de uso das espécies aos seus parâmetros fitossociológicos, estimados a partir de dados de 16 parcelas de 20×30 m, estabelecidas em cinco fragmentos florestais mais bem conservados. Os maiores conhecedores das plantas e seus usos foram considerados informantes-chave e os demais entrevistados integraram a comunidade em geral. Foram identificadas oito categorias de uso: construção doméstica, construção rural, medicinal, alimentação, forragem, tecnologia, energético e outros usos não madeireiros. A vegetação do local foi caracterizada pela presença de Ziziphus joazeiro Mart., Crataeva tapia L., Lonchocarpus sericeus (Poir. DC., Tabebuia aurea (Silva Manso Benth. & Hook. F. ex S. Moore, Geoffroea spinosa Jacq., Schnopsis brasiliensis Engl., Sapindus saponaria L., Albizia inundata (Mart. Barneby & Grimes e Triplaris gardneriana Wedd. Os entrevistados atribuíram usos para 34 espécies entre as quais destacaram-se com maiores valores de uso a T. aurea, com 6,44 para os informantes-chave e 4,10 para a comunidade em geral; Anadenanthera colubrina (Vell. Benan. var. cebil (Griseb Altschul., 4,81 para os informantes-chave e 3,53 para a comunidade em geral e S. brasiliensis, 4,25 para os informantes-chave e 4,47 para a comunidade em geral. O maior número de espécies conhecidas é utilizado para forragem, embora o maior componente do valor de uso total tenha sido as construções rurais. Os parâmetros fitossociológicos estimados não apresentaram correlação com os valores de uso atribuídos às espécies. A importância das formações ciliares foi ressaltada não só para a conservação dos recursos hídricos e para o atendimento das necessidades da comunidade local, mas como garantia de perpetua
