    Full Text Available O fungo Ceratobasidium spp. é o agente causal da doença mal-do-fio ou queima-do-fio em várias plantas frutíferas, em cafeeiro e em chá. Esta doença ocorre com maior freqüência em zonas de alta precipitação e temperaturas elevadas, típicas de regiões de florestas tropicais como a Amazônica e a Mata Atlântica. Em São Paulo, o primeiro relato do mal-do-fio em caquizeiro ocorreu na região de Mogi das Cruzes. O objetivo deste estudo foi testar a patogenicidade cruzada de isolados de Ceratobasidium spp. de caquizeiro e chá para ambas as culturas e também para o cafeeiro e citros. Avaliou-se, também, a reação de oito cultivares de caquizeiro, sob condições controladas, a isolados de Ceratobasidium spp. obtidos da mesma cultura. Constatou-se que os isolados de caquizeiro e de chá, embora filogeneticamente distintos, foram patogênicos para ambas as culturas, além de afetarem cafeeiro e citros. Não foram verificados indícios de reação de resistência aos isolados de Ceratobasidium spp. para as oito cultivares de caquizeiro testadas.The fungus Ceratobasidium spp. causes the white-thread blight disease, which affects several fruit trees, coffee and tea crops. This disease frequently occurs in zones of high precipitation and temperatures, typical of the tropical forest regions such as the Amazon and the Atlantic Forests. In São Paulo State, Brazil, this disease was reported by the first time affecting kaki plants in Mogi das Cruzes county. The objective of this study was to test the cross-pathogenicity of Ceratobasidium spp. isolates from kaki and tea to both host plants and also to coffee and citrus. This study also aimed to determine the reaction of local kaki varieties to Ceratobasidium spp. isolates from kaki under controlled conditions. Although phylogenetically distinct, kaki- and tea-infecting isolates were cross-pathogenic to both hosts, besides infecting coffee and citrus. There was no indication of resistance reaction

    Persimmon (Diospyros kaki Thunb.) is a temperate fruit tree species diffused in all continents. The traditional propagation method adopted by the nursery industry is based on budding/grafting scion cultivars on seedlings from D. kaki, Diospyros lotus, and Diospyros virginiana, the most important species used as rootstock, reproduced by seeds since they are not easy to root. Furthermore, most of nonastringent cultivars of persimmon are not compatible with D. lotus, a rootstock largely utilized because of its hardiness and frost resistance. The main in vitro tissue culture techniques, developed for persimmon, deal with direct regeneration (from dormant buds and root tips), and indirect regeneration through callus from dormant buds, apexes, and leaves. The bottlenecks of micropropagation are (1) the recalcitrance of many cultivars to in vitro establishment, (2) the low multiplication ratio of D. kaki compared to other fruit tree species, (3) the very low rooting ability of ex novo microcuttings both from direct and indirect regeneration, (4) the high sensitivity to transplant from in vitro to in vivo conditions. The development of reliable in vitro regeneration procedures is likely to play a key role for production of both clonal rootstocks and self-rooted cultivars. The general protocol for micropropagation of persimmon reported here is based on the establishment of winter dormant buds in vitro, shoot development, multiplication and elongation, and shoot rooting, using cytokinins (BA or zeatin) in a MS media along with an auxinic pretreatment for rooting induction.

    Full Text Available A cultura do caquizeiro vem crescendo em importância no Brasil e, com o aumento do cultivo, tem havido também incremento dos problemas relacionados a doenças e pragas. A pulverização de agrotóxicos é o método mais utilizado na prevenção e no controle desses problemas e a principal forma de aplicação é a pulverização hidráulica com auxílio de fluxo de ar. O objetivo deste trabalho foi avaliar o efeito da variação da taxa de aplicação e do repasse na parte interna das plantas em pulverização com pistola manual, na cobertura de calda das folhas. A pulverização foi realizada em plantas de caquizeiro com 17 anos, utilizando-se equipamento composto de trator e pulverizador turboatomizador. A aplicação foi realizada com duas velocidades de avanço do equipamento, o que promoveu diferentes taxas de aplicação. Para a realização do repasse, utilizou-se pistola manual acoplada ao mesmo equipamento. Para a avaliação da cobertura, utilizou-se calda preparada com corante fluorescente dissolvido em água. Foram coletadas folhas nas posições externa e interna das plantas. Posteriormente, em sala escura e com iluminação ultravioleta para destacar a área atingida pelo corante fluorescente, as superfícies abaxial e adaxial de cada folha foram fotografadas com câmera digital. Cada imagem gerada foi submetida à análise pelo software SIARCS 3.0, resultando em porcentagem de cobertura.

    The bile acid-binding ability of a highly polymerized tannin (kaki-tannin) extracted from dried-young fruits of persimmon (Diospyros kaki) was examined. The kaki-tannin was composed mainly of epicatechin, epigallocatechin, epicatechin-3-O-gallate and epigallocatechin-3-O-gallate. Bile acid-binding ability of kaki-tannin was examined against cholic acid, glycocholic acid, taurocholic acid and deoxycholic acid in vitro, and its effect on fecal bile acid excretion in mice was also examined. Although the bile acid-binding ability of kaki-tannin was weaker than that of cholestyramine, kaki-tannin adsorbed all the bile acids tested and significantly promoted fecal bile acid excretion in mice when supplied at 1% (w/w) in the diet.

    Extraction of carotenoids from biological matrices and quantifications remains a difficult task. Accelerated solvent extraction was used as an efficient extraction process for carotenoids extraction from three fruits cultivated in Tunisia: kaki (Diospyros kaki L.), peach (Prunus persica L.) and apricot (Prunus armeniaca L.). Based on a design of experiment (DoE) approach, and using a binary solvent consisting of methanol and tetrahydrofuran, we could identify the best extraction conditions as being 40°C, 20:80 (v:v) methanol/tetrahydrofuran and 5 min of extraction time. Surprisingly and likely due to the high extraction pressure used (103 bars), these conditions appeared to be the best ones both for extracting xanthophylls such as lutein, zeaxanthin or β-cryptoxanthin and carotenes such as β-carotene, which present quite different polarities. Twelve surface responses were generated for lutein, zeaxanthin, β-cryptoxanthin and β-carotene in kaki, peach and apricot. Further LC-MS analysis allowed comparisons in carotenoids profiles between the fruits. PMID:25872435

    Dried fruits of persimmon (Diospyros kaki Thunb.) are a traditional food in Japan and contain large quantities of tannins. In this study, we investigated the in vitro and in vivo antioxidant potentials of non-extractable fractions from dried persimmons. Hydrolysed non-extractable fractions showed the highest antioxidant activities in vitro. In subsequent experiments, the plasma oxygen radical absorbance capacity (ORAC) values in rats supplemented with a 5% non-extractable fraction were approximately 1.5times higher than those in control rats after 1week in vivo. Furthermore, using an in vitro model of the gastrointestinal tract, the ORAC values of the non-extractable fraction were significantly increased with colonic fermentation in the large bowel stage. These data indicate that non-extractable fractions may possess significant antioxidant potential in vitro and in vivo. PMID:26920271

    Diospyros kaki is cultivated in different agro-ecological zones of Pakistan, especially in Malakand division. The current study was designed to investigate the hide potential of the vulnerable species of the plant. Aqueous extracts of Diospyros kaki leaves were screened for larvicidal, insecticidal cytotoxic and antioxidant activities. The extract exhibited moderate to outstanding larvicidal activity (100 to 28%) at 100, 80, 70, 50, 40, 30, 20 and 10% concentrations respectively after 24 hours, showing 42% LC₅₀. Permitrin displayed 100% lethality at 0.3%. The extract demonstrated outstanding cytotoxic action against brain shrimps nauplii (Artemia salina), showing 10 ppm LC50 which is closed to the LC50 (9.8μg/ml) of standard drug Etoposide. Similarly profound insecticidal potential (100%) was recorded after 15 min against Cimex lectularius. In DPPH scavenging activity the extract demonstrated moderate 30.22%, while Quercetin, Gallic acid and Acetic acid showed 98, 96 and 97% activity respectively at 100 ppm. Thus on the basis of our finding it could be concluded that the decoction of the leaves of D. kaki is a good natural alternative for the control of insects and neoplasia. PMID:26142513

    Supercritical carbon dioxide with ethanol as co-solvent was used to extract carotenoids from persimmon fruits (Diospyros kaki L.). Based on a response surface methodology (RSM), a predicting model describing the effects of CO2 temperature, pressure, flow rate, ethanol percentage and extraction time was set up for each of the four carotenoids of interest. The best extraction yields in our experimental domain were found at 300 bars, 60°C, 25% (w/w) ethanol, 3mL/min flow rate and 30min for xanthophylls (all-trans-lutein, all-trans-zeaxanthin and all-trans-β-cryptoxanthin). The yields were 15.46±0.56, 16.81±1.74 and 33.23±2.91μg/g of persimmon powder for all-trans-lutein, all-trans-zeaxanthin and all-trans-β-cryptoxanthin, respectively. As a non-oxygenated carotenoid, all-trans-β-carotene was better extracted using 100 bars, 40°C, 25% (w/w) ethanol, 1mL/min flow rate and 30min extraction time, with an extraction yield of 11.19±0.47μg/g of persimmon powder.

    Full Text Available Salinity continues to be a major factor in reduced crop productivity and profit in many arid and semiarid regions. Seedlings of Diospyros kaki Thunb. and D. virginiana L. are commonly used as rootstock in persimmon cultivation. In this study we have evaluated the effects of different salinity levels on photosynthetic capacity and plant development of D. kaki and D. virginiana. Salinity was provided by adding 50 mM, 75 mM and 100 mM NaCl to nutrient solution. In order to determine the effects of different salinity levels on plant growth, leaf number, plant height, shoot and root dry mass were recorded. Besides leaf Na, Cl, K and Ca concentrations were determined. Also leaf chlorophyll concentration, chlorophyll fluorescence (Fv’/Fm’ and leaf gas exchange parameters including leaf net photosynthetic rate (PN, stomatal conductance (gS, leaf transpiration rate (E, and CO2 substomatal concentration (Ci were investigated. Significant decrease of leaf number, shoot length and plant dry mass by increasing salinity levels was observed in both rootstocks. D. virginiana was less affected in terms of plant growth under salinity stress. Leaf chlorophyll concentration reduction was higher in the leaves of D. kaki in comparison to D. virginiana in 100 mM NaCl treatment. By increasing salinity levels PN, gS and E markedly decreased in both rootstocks and D. kaki was more affected from salinity in terms of leaf gas exchange parameters. In addition there was no significant difference but slight decreases were recorded in leaf chlorophyll fluorescences of both rootstocks.

    Full Text Available The feasibility of using the bio-photonic imaging technique to assess symptoms of circular leaf spot (CLS disease in Diospyros kaki (persimmon leaf samples was investigated. Leaf samples were selected from persimmon plantations and were categorized into three groups: healthy leaf samples, infected leaf samples, and healthy-looking leaf samples from infected trees. Visually non-identifiable reduction of the palisade parenchyma cell layer thickness is the main initial symptom, which occurs at the initial stage of the disease. Therefore, we established a non-destructive bio-photonic inspection method using a 1310 nm swept source optical coherence tomography (SS-OCT system. These results confirm that this method is able to identify morphological differences between healthy leaves from infected trees and leaves from healthy and infected trees. In addition, this method has the potential to generate significant cost savings and good control of CLS disease in persimmon fields.

    Full Text Available Ischemic cerebrovascular disease is one of the most common causes of death in the world. Recent interests have been focused on natural antioxidants and anti-inflammatory agents as potentially useful neuroprotective agents. Diospyros kaki (persimmon has been shown to exert anti-inflammatory, antioxidant, and antineoplastic effects. However, its effects on ischemic damage have not been evaluated. Here, we used an in vitro model of cerebral ischemia and studied the effects of hydroalcoholic extract of peel (PeHE and fruit pulp (PuHE of persimmon on cell viability and markers of oxidative damage mainly intracellular reactive oxygen species (ROS induced by glucose-oxygen-serum deprivation (GOSD in PC12 cells. GOSD for 6 h produced significant cell death which was accompanied by increased levels of ROS. Pretreatment with different concentrations of PeHE and PuHE (0–500 μg/mL for 2 and 24 h markedly restored these changes only at high concentrations. However, no significant differences were seen in the protection against ischemic insult between different extracts and the time of exposure. The experimental results suggest that persimmon protects the PC12 cells from GOSD-induced injury via antioxidant mechanisms. Our findings might raise the possibility of potential therapeutic application of persimmon for managing cerebral ischemic and other neurodegenerative disorders.

    The hypolipidemic effects and bile acid-binding properties of young persimmon (Diospyros kaki) fruit were examined. In an animal experiment, male C57BL/6.Cr mice (n = 5) were fed an AIN-76-modified high fat diet supplemented with 2% or 5% (w/w) dried young persimmon fruit (YP) for 10 weeks. The intake of YP significantly enhanced fecal bile acid excretion and lowered the concentration of hepatic lipids and plasma cholesterol. Analysis of gene expression in liver tissue showed that 2% or 5% YP up-regulated the expression of the sterol regulatory element-binding protein-2 gene. In the 5% group, there were increased expressions of the genes for cholesterol 7alpha-hydroxylase and the low-density lipoprotein receptor. Next, the bile acid-binding ability of YP was analysed in vitro using cholic acid (CA). In 100-2000 microM CA solutions, 1% (w/v) YP adsorbed approximately 60% of CA, while dried mature persimmon fruit adsorbed approximately 20% of CA. The positive control, cholestyramine, adsorbed approximately 80% of CA in the 100-2000 microM CA solutions. A crude tannin extract from YP, which contained 54.7% condensed tannins, adsorbed approximately 78% of CA in the 2000 microM CA solutions. These results suggest that the ability of YP to bind bile acid contributes to its hypolipidemic effect in mice. PMID:19585467

    Pancreatic lipase is the enzyme responsible for digestion and absorption of triglycerides, being its inhibition one of the widest studied methods used to determine the potential activity of natural products to inhibit dietary fat absorption. Decrease of energy intake from dietary fat through inhibition of this enzyme may be an excellent strategy to prevent and treat obesity. The inhibitory activity on pancreatic lipase enzyme of Diospyros kaki fruit and Citrus unshiu peel mixture extract (PCM) was evaluated in vitro and its antiobesity effects were studied based on the serum lipid parameters analysis from high-fat diet- (HFD-) fed mice in vivo. PCM was orally administered at a dose of 50 and 200 mg/kg body weight for 6 weeks. In addition, the activity of pancreatic lipase was assessed using orlistat (positive control). PCM exhibited inhibitory effect on lipase activity with IC50 value of 507.01 μg/mL. Moreover, serum triacylglycerol, total cholesterol levels, and visceral fat weight were significantly reduced compared to HFD control mice in PCM 200 mg/kg-treated mice (p absorption via inhibition of pancreatic lipase.

    Irradiation effects on color and functional properties of persimmon (Diospyros kaki L. folium) leaf extract and licorice (Glycyrrhiza Uralensis Fischer) root extract were studied. Persimmon leaf and licorice root extracts were irradiated using {sup 60}Co gamma irradiator at 0 and 20 kGy absorbed dose and stored at 4 deg. C or -20 deg. C for 2 weeks. Tyrosinase inhibition effect (TIE) of both extracts was not different by 20 kGy-irradiation but reduced during storage. Electron donating ability (EDA) of the persimmon leaf extract was generally consistent, but that of licorice root extract was reduced by irradiation except for 1 week of storage. Both TIE and EDA of persimmon leaf extract were higher than that of licorice root. Hunter color L*-, a*-, and b*-values were changed, resulting in a desirable brighter color by irradiation. During storage, the bright yellow color of irradiated sample changed to brown gradually, and especially the changes in the refrigeration condition (4 deg. C) was faster than frozen (-20 deg. C). Results indicate that irradiation can be a useful method to produce value-added natural ingredients with functions such as persimmon leaf or licorice root for food or cosmetic industry in addition to elimination of microbial load.

  19. Inactivation of pathogenic viruses by plant-derived tannins: strong effects of extracts from persimmon (Diospyros kaki on a broad range of viruses.

    Kyoko Ueda

    Full Text Available Tannins, plant-derived polyphenols and other related compounds, have been utilized for a long time in many fields such as the food industry and manufacturing. In this study, we investigated the anti-viral effects of tannins on 12 different viruses including both enveloped viruses (influenza virus H3N2, H5N3, herpes simplex virus-1, vesicular stomatitis virus, Sendai virus and Newcastle disease virus and non-enveloped viruses (poliovirus, coxsachievirus, adenovirus, rotavirus, feline calicivirus and mouse norovirus. We found that extracts from persimmon (Diospyros kaki, which contains ca. 22% of persimmon tannin, reduced viral infectivity in more than 4-log scale against all of the viruses tested, showing strong anti-viral effects against a broad range of viruses. Other tannins derived from green tea, acacia and gallnuts were effective for some of the viruses, while the coffee extracts were not effective for any of the virus. We then investigated the mechanism of the anti-viral effects of persimmon extracts by using mainly influenza virus. Persimmon extracts were effective within 30 seconds at a concentration of 0.25% and inhibited attachment of the virus to cells. Pretreatment of cells with the persimmon extracts before virus infection or post-treatment after virus infection did not inhibit virus replication. Protein aggregation seems to be a fundamental mechanism underlying the anti-viral effect of persimmon tannin, since viral proteins formed aggregates when purified virions were treated with the persimmon extracts and since the anti-viral effect was competitively inhibited by a non-specific protein, bovine serum albumin. Considering that persimmon tannin is a food supplement, it has a potential to be utilized as a safe and highly effective anti-viral reagent against pathogenic viruses.

    Full Text Available O objetivo deste trabalho foi avaliar o efeito do período de exposição ao vapor de álcool etílico na remoção da adstringência de frutos de caquizeiro (Diospyros kaki L. cultivar Giombo. Os frutos foram expostos ao vapor de álcool durante 24, 36 e 48 horas, sob temperatura de 20°C e 95% de umidade relativa. As características químicas e físicas dos frutos foram avaliadas durante dez dias, em intervalos de dois dias. As variáveis analisadas foram: teor de taninos solúveis, firmeza da polpa, perda de matéria fresca, pH, sólidos solúveis totais, acidez total titulável e teor de ácido ascórbico. De acordo com os resultados obtidos, os períodos de 24 e 36 horas demonstraram ser igualmente eficientes no processo de remoção da adstringência dos frutos; no entanto, a avaliação das demais características indicou melhor qualidade dos frutos expostos durante o período de 24 horas. Constatou-se uma diminuição linear na firmeza da polpa em função do tempo. O melhor período para consumo dos frutos situou-se entre o 4°e o 8° dia após o tratamento, considerando-se que a partir do 4° dia a concentração de taninos solúveis ficou abaixo de 0,1%, imperceptível ao paladar, e a firmeza da polpa dos frutos se manteve aceitável durante o período de oito dias posteriores ao tratamento.

    Full Text Available Selection of suitable pollinizers is very important for persimmon that have a widespread problem in fruit setting. This study aims to contribute for solving this problem. Study was carried out in 2010 vegetation period with 17 years old persimmon trees in Adana conditions. For this purpose, the suitability of Bruniquel and Ghora Gali pollinizer cultivars were searched for 9 local persimmon types (07TH05, 07TH06, 07TH13, 07TH14, 07TH17, 31TH01, 31TH02, 31TH03 and 33TH01. In laboratory tests of pollen viability, germination and quantity, it was determined that the potential of Ghora Gali and Bruniquel is satisfactory for a pollinizer. With controlled-pollination treatments, fruit drop was reduced compared with open pollination and non-pollination treatments. In terms of this, the best pollinator for 07TH14 and 33TH01 was Bruniquel and for 07TH06 and 07TH17 it was Ghora Gali. Both Bruniquel and Ghora Gali became suitable pollinators for 07TH05. In 07TH13, 31TH02 and 31TH03 genotypes, the best results were obtained from open pollination treatments. At the same time, 07TH14 and 33TH01 genotypes have high affinity to parthenocarpy because of their fruit set ability while there is not any pollinizer.

Os frutos foram avaliados após 3 meses de armazenamento mais 3 dias de exposição à temperatura ambiente (18-20ºC. Conforme os resultados, não foi constatada interação entre os fatores, havendo efeito significativo para temperatura somente na firmeza de polpa, em que -1,0ºC apresentou frutos mais firmes. As diferentes pressões parciais de CO2 não influenciaram a perda de peso e a firmeza de polpa. As podridões apresentaram uma resposta linear negativa em relação ao CO2, porém, mantendo elevada ocorrência. Valores de CO2 entre 5 e 10kPa proporcionaram frutos com menor índice de escurecimento de epiderme e com coloração mais amarela e vermelha. O CO2 entre 5 e 10kPa apresentou os melhores resultados, que somados à temperatura de -1,0ºC, foi a melhor condição de armazenamento, que, no entanto, teve o período de conservação inferior a três meses nesta condição, devido às altas perdas por podridões.

Os experimentos a campo consistiram numa série de trabalhos que envolveram a estaquia de caule e de raiz, a mergulhia e a alporquia do caquizeiro 'Fuyu'. Na estaquia de caule, foram testados o número de folhas, concentrações de AIB, o estiolamento localizado e total. Na estaquia de raiz, foram testados o diâmetro e a posição da estaca. A mergulhia foi testada a campo e em recipientes, sendo combinanda com o estiolamento das brotações, anelamento e aplicação de AIB. Na alporquia, foram testados o anelamento e a aplicação de AIB, sendo os alporques utilizados para outro teste com AIB. Os experimentos in vitro foram conduzidos com plantas juvenis, sendo um trabalho realizado para a indução de organogênese a partir de segmentos radiculares com BAP, TDZ e cinetina (10µM, combinados com AIA (0,01µM, e outro para a indução do enraizamento de brotações pela permanência em meio de cultura com 25mg.L-1 de AIB e posterior transferência para outro meio de cultura isento de reguladores de crescimento e com carvão ativado. Em todos os experimentos de estaquia de caule, mergulhia e alporquia, não ocorreu a formação de raízes. Apenas na estaquia de raiz houve organogênese, onde as melhores respostas de brotação e enraizamento foram obtidas com as estacas de maior diâmetro e na posição vertical. A organogênese também foi observada em segmentos radiculares in vitro, com uma grande proliferação de calos e gemas induzida pelo uso de TDZ mais AIA. Ao contrário do observado a campo, as brotações caulinares in vitro enraizaram com uma taxa de 66%, com uma emissão média de 4,7 raízes por brotação, mostrando ser uma técnica promissora de clonagem do caquizeiro.

    This study aims to analyze the antioxidant benefits from persimmon leaf tea, fruit and fibres taking into account their changes along gastrointestinal digestion. The evolution of polyphenols, flavonoids and antioxidant capacity was studied using the recent harmonized in vitro protocol published by Minekus et al. (2014). The digestion was performed with and without digestive enzymes. Results showed aqueous leaf extract was richer in antioxidants than the fruit or the extracted fibres. Nevertheless, persimmon-leaf antioxidants were more sensitive to the digestive environment. In general, the oral conditions greatly affected the antioxidants, while gastric digestion led to slight additional losses. The intestinal step enhanced polyphenols and flavonoids solubility coming from the fruit and fibres. Additionally, the presence of digestive enzymes positively contributed to antioxidant release throughout digestion. Finally, the bioaccessibility of polyphenols, flavonoids and antioxidant activity of persimmon fruit were 1.4, 1.0 and 3.8 times higher than in aqueous leaf extract. PMID:27507501

    Full Text Available Abstract Aim Diospyros Lotus (“Wild Date Palm of Trabzon or Persimmon”, which has been proven to cause phytobezoars, is a widely consumed fruit in the Black Sea and Northeast Anatolia regions of Turkey. The aim of the present study was to investigate the effects of Diospyros Lotus together with other predisposing factors, on the development of gastrointestinal phytobezoars and to discuss the treatment results in comparison to the literature. Material and method The records of 13 patients, who had been admitted to the General Surgery Clinic of Düzce Atatürk State Hospital between August 2008 and August 2011, were retrospectively reviewed. Demographic characteristics, predisposing factors, clinical and radiological findings, diagnostic and therapeutic methods, and the outcomes of the patients were recorded from the patient files. Written informed consent was obtained from each patient for publication of this research article and accompanying images. Results All the patients had a history of consuming Diospyros Lotus. Of the patients, 30,7% had a history of previous gastric surgery, 30,7% had diabetes mellitus and 23% had dental implants. None of the patients had hypothyroidism, which is another predisposing factor for phytobezoars. The phytobezoars were located in the stomach alone in 23% of the patients, whereas 15,3% was detected in the jejunum and stomach, 15,3% was detected in the jejunum alone, and 46,1% was detected in the ileum alone. All patients were treated with surgery, and there were no deaths. Conclusion Gastric phytobezoars are rare. Preventive measures have particular importance in the management of this condition, which is difficult to treat. For this purpose, excessive consumption of herbal nutrients containing a high amount of indigestible fibers such as Diospyros Lotus should be avoided in patients with a history of gastrointestinal surgery or poor oral and dental health.

    Objective: To evaluate pharmacologically the traditional use of Diospyros lotus as antipyretic and antinociceptive in various animal models.Methods: In vivo experimental models were used in this study. Antipyretic activity of extract/fractions was evaluated in brewer’s yeast induced hyperthermic mice while antinociceptive activity was studied in acetic acid induced writhing test at 50 and 100 mg/kg i.p.Results:The crude extract strongly ameliorated the induced pyrexia during various assessment times. Upon fractionation, the antipyretic effects were strongly augmented by the chloroform and ethyl acetate fractions of the plant. However, hexane and butanol fractions were insignificant in their effect as antipyretic. The extract showed marked inhibition on the noxious simulation induced by post acetic acid injection. The effect was strongly supported by other fraction expect hexane.Conclusions:In short, our study scientifically validated the traditional use of the plant as antipyretic.

    Objective: To investigate the comparative effects of Diospyros blancoi (Ebenaceae) leaves (DBL), root bark (DBRB) and stem bark (DBSB) on free radicals and cancer. Methods: The polyphenol contents, antioxidant and free radical scavenging properties were determined using standard spectrophotometric methods. Cytotoxicity and anticancer activ-ities were performed on brine shrimp nauplii and Ehrlich ascite carcinoma cells, respectively. Results: Among the extracts, DBSB showed the highest total antioxidant capacity and reducing capacity on ferrous ion. Based on 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radical scavenging activities, DBSB showed (95.760 ± 0.343)%and (67.460 ± 2.641)%scavenging with IC50 of (3.10 ± 0.17) and (50.00 ± 3.11) mg/mL, respectively. The IC50 values of standard butylated hydroxytoluene and catechin (CA) for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals were (8.50 ± 0.25) and (75.00 ± 0.14) mg/mL, respectively suggesting that DBSB had a significant (P DBRB > CA > DBL. Also, the phenolic [(139.91 ± 3.924) mg gallic acid equivalent/g] and flavonoid contents [(412.00 ± 16.70) mg catechin equivalent/g)] of DBSB were higher than that of other extracts. In addition, the DBSB showed the moderate cytotoxic and anticancer properties. Conclusions: Our results indicate that Diospyros blancoi stem bark had the significant highest antioxidant and free radical scavenging properties as well as moderate anticancer activity. Hence, we assume that the anticancer activity of this plant can be, at least in part, attributed to its content in phenolic compounds as well as its significant free radical scavenging properties.

    Objective:To isolate and characterize the cytotoxic compounds from Diospyros quercina (Baill.) G.E. Schatz&Lowry (Ebenaceae). Methods: An ethno-botanical survey was conducted in the south of Madagascar from July to August 2010. Bio-guided fractionation assay was carried out on the root bark of Diospyros quercina, using cytotoxicity bioassay on murine P388 leukemia cell lines as model. The structures of the cytotoxic compounds were elucidated by 1D and 2D NMR spectroscopy and mass spectrometry. Results: Biological experiments resulted in the isolation of three bioactive pure compounds (named TR-21, TR-22, and TR-23) which exhibited very good in vitro cytotoxic activities with the IC50 values of (0.017 5±0.0060) µg/mL, (0.089±0.005) µg/mL and (1.027±0.070) µg/mL respectively. Thus, they support the claims of traditional healers and suggest the possible correlation between the chemical composition of this plant and its wide use in Malagasy folk medicine to treat cancer. Conclusions:The ability of isolated compounds in this study to inhibit cell growth may represent a rational explanation for the use of Diospyros quercina root bark in treating cancer by Malagasy traditional healers. Further studies are, therefore, necessary to evaluate the in vivo anti-neoplastic activity of these cytotoxic compounds as effective anticancer drugs.

    Cervical cancer is among the most prevalent forms of cancer in women worldwide. Diospyros lycioides was extracted using hexane, ethyl acetate, acetone, and methanol and finger print profiles were determined. The leaf material was tested for the presence of flavonoids, tannins, saponins, terpenoids, and cardiac glycosides using standard chemical methods and the presence of flavonoids and phenolics using thin layer chromatography. The total phenolic content was determined using Folin-Ciocalteu procedure. The four extracts were tested for antibacterial activity using bioautography against Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Escherichia coli. The acetone extract with the highest number of antibacterial and antioxidant compounds was assessed for its cytotoxicity on BUD-8 cells using the real-time xCELLigence system and its potential effects on metastatic cervical cancer (HeLa) cell migration and invasion were assessed using wound healing migration and invasion assays. The leaf extract tested positive for flavonoids, tannins, and terpenoids while the four different extracts tested in the antimicrobial assay contained constituents active against one or more of the organisms tested, except E. coli. The cytotoxicity of the acetone extract in real-time was concentration-dependent with potent ability to suppress the migration and invasion of HeLa cells. The finding demonstrates the acetone extract to contain constituents with antibacterial and antimetastatic effects on cervical cancer cells. PMID:27239210

    Since the discovery and subsequent widespread use of antibiotics, a variety of bacterial species of human and animal origin have developed numerous mechanisms that render bacteria resistant to some, and in certain cases to nearly all antibiotics, thereby limiting the treatment options and compromising effective therapy. In the present study, the green synthesis of nanoparticles is carried out by the reduction of silver acetate in the presence of crude methanolic root extracts of Diospyros paniculata, a member of family Ebenaceae. The UV-Vis absorption spectrum of the biologically reduced reaction mixture showed the surface plasmon peak at 428nm, a characteristic peak of silver nanoparticles. X-ray diffraction (XRD) analysis confirmed the face-centered cubic crystalline structure of metallic silver. The average diameter of Ag NPs is about 17nm from Transmission Electron Microscopy (TEM) which is in good agreement with the average crystallite size (19nm) calculated from XRD analysis. Further the study has been extended to the antimicrobial activity against test pathogenic Gram (+), Gram (-) bacterial and fungal strains. The biologically synthesized silver nanoparticles showed promising activity against all the tested pathogenic strains and the activity has been enhanced with the increased dose levels. PMID:26952458

    Objective: To evaluate the sedative effect of Diospyros lotus L(D. lotus) extract in mice using the open field and Rota rod tests.Methods: For the sedative and muscle relaxants activities of extract/fractions of the plant, invivo open field and phenobarbitone-induced sleeping time were used, while the Roda rod test was employed in animals for the assessment of muscle relaxant activity.Results: Results from this investigation revealed that the extracts of D. lotus have exhibited significant sedative effect in mice(45.98%) at 100 mg/kg i.p. When the extract was partitioned with different solvents, the n-hexane fraction was inactive whereas the chloroform fraction was the most active with 82.67% sedative effect at 50 and 100 mg/kg i.p. On the other hand,the ethyl acetate and n-butanol fractions displayed significant sedative effects(55.65% and40.87%, respectively) at 100 mg/kg i.p. Among the tested extract/fractions, only chloroform and ethyl acetate fractions showed significant(P < 0.05) muscle relaxant activity in the Rota rod test.Conclusions: In short, our study provided scientific background to the traditional uses of D.lotus as sedative.

    Due to its special geological history, the New Caledonian Archipelago is a mosaic of soil types, and in combination with climatic conditions this results in a heterogeneous environment across relatively small distances. A group of over 20 endemic species of Diospyros (Ebenaceae) has rapidly and recently radiated on the archipelago after a single long-distance dispersal event. Most of the Diospyros species in the radiating group are morphologically and ecologically well differentiated, but they exhibit low levels of DNA variability. To investigate the processes that shaped the diversification of this group we employed restriction site associated DNA sequencing (RADseq). Over 8400 filtered SNPs generally confirm species delimitations and produce a well-supported phylogenetic tree. Our analyses document local introgression, but only a limited potential for gene flow over longer distances. The phylogenetic relationships point to an early regional clustering among populations and species, indicating that allopatric speciation with respect to macrohabitat (i.e., climatic conditions) may have had a role in the initial differentiation within the group. A later, more rapid radiation involved divergence with respect to microhabitat (i.e., soil preference). Several sister species in the group show a parallel divergence in edaphic preference. Searches for genomic regions that are systematically differentiated in this replicated phenotypic divergence pointed to loci potentially involved in ion binding and cellular transport. These loci appear meaningful in the context of adaptations to soil types that differ in heavy-metal and mineral content. Identical nucleotide changes affected only two of these loci, indicating that introgression may have played a limited role in their evolution. Our results suggest that both allopatric diversification and (parapatric) ecological divergence shaped successive rounds of speciation in the Diospyros radiation on New Caledonia. PMID:26430059

    The water maceration and methanolic extract of the stem barks of Diospyros bipindensis, which is a medicinal plant used in Cameroon by Baka pygmies, revealed a complex high-performance liquid chromatography (HPLC) profile primarily composed of coumarin and naphthoquinone glycosides. The methanolic and apolar extracts also exhibited significant antifungal activity on a TLC bioautography assay against Candida albicans. HPLC-microfractionation in 96-well plates combined with bioautography enabled the rapid localization of the antifungal compound that was identified by HPLC-PDA and HPLC-MS analysis as plumbagin. These on-line structural information were also used to dereplicate four known compounds. The isolation of the polar constituents from the methanolic extract enabled the identification of eleven other compounds also present in the traditional preparation, nine of which are reported for the first time. The structures of those compounds were elucidated by UV, NMR and HR-MS analysis. PMID:24070618

    Full Text Available Diospyros blancoi A. DC. is an evergreen tree species of high-quality wood. Mabolo, the fruit of this plant, is popular among the natives in Taiwan, but its potential in economic use has not been fully explored. Mabolo has a rich aroma. Of the 39 different volatile compounds isolated, its intact fruit and peel were found to both contain 24 compounds, whereas the pulp contained 28 compounds. The most important aroma compounds were esters and α-farnesene. Our data show that mabolo is rich in dietary fiber (3.2%, and the contents of other nutrients such as malic acid, vitamin B2, vitamin B3, folic acid, pantothenic acid, and choline chloride were 227.1 mg/100 g, 0.075 mg/100 g, 0.157 mg/100 g, 0.623 mg/100 g, 0.19 mg/100 g, and 62.52 mg/100 g, respectively. Moreover, it is rich in calcium and zinc; the contents of which were found to be 42.8 mg/100 g and 3.6 mg/100 g, respectively. Our results show that D. blancoi has the potential to be bred for a novel fruit.

    Background and Aims Some plant groups, especially on islands, have been shaped by strong ancestral bottlenecks and rapid, recent radiation of phenotypic characters. Single molecular markers are often not informative enough for phylogenetic reconstruction in such plant groups. Whole plastid genomes and nuclear ribosomal DNA (nrDNA) are viewed by many researchers as sources of information for phylogenetic reconstruction of groups in which expected levels of divergence in standard markers are low. Here we evaluate the usefulness of these data types to resolve phylogenetic relationships among closely related Diospyros species. Methods Twenty-two closely related Diospyros species from New Caledonia were investigated using whole plastid genomes and nrDNA data from low-coverage next-generation sequencing (NGS). Phylogenetic trees were inferred using maximum parsimony, maximum likelihood and Bayesian inference on separate plastid and nrDNA and combined matrices. Key Results The plastid and nrDNA sequences were, singly and together, unable to provide well supported phylogenetic relationships among the closely related New Caledonian Diospyros species. In the nrDNA, a 6-fold greater percentage of parsimony-informative characters compared with plastid DNA was found, but the total number of informative sites was greater for the much larger plastid DNA genomes. Combining the plastid and nuclear data improved resolution. Plastid results showed a trend towards geographical clustering of accessions rather than following taxonomic species. Conclusions In plant groups in which multiple plastid markers are not sufficiently informative, an investigation at the level of the entire plastid genome may also not be sufficient for detailed phylogenetic reconstruction. Sequencing of complete plastid genomes and nrDNA repeats seems to clarify some relationships among the New Caledonian Diospyros species, but the higher percentage of parsimony-informative characters in nrDNA compared with

  12. Effects of radiation doses and storage temperatures on persimmon (Dyospyrus kaki L.) at pre-climateric and pos-climateric phases

    International Nuclear Information System (INIS)

    The present research was conducted to evaluate the effects of radiation doses and storage temperatures on persimmon (Diospyrus Kaki L.) at preclimateric and post-climateric phases. Two lots of 48 samples of greens and matures persimmon were utilized in two independent experiments. The samples were irradiated with 0.0 (control), 0.5, 0.6, 0.7, 0.8 and 0.9 kGy in a Cobalt-60 source. After the irradiation the samples were stored at environmental temperature (22-250 C) and under refrigeration (5-70 C). The samples stored under refrigeration showed more resistent to compression in both mature and green persimmon. The radiation process effect was better verified on gree khakis with 0.9 kGy to the fruit stored at environmental temperature, and 0.6 kGy to the refrigerated samples; the persimmon irradiated with 0.9 and 0.6 kGy, showed more resistence to compression, on both environmental and refrigeration temperatures.

A utilização da câmara fria (4ºC, uso comercial manteve a boa firmeza dos frutos para a comercialização acima de 16 dias, para os frutos, sem e com a aplicação de promalina no pomar, enquanto que, na temperatura ambiente (20-26ºC, os tempos foram de 16 e oito dias, respectivamente. A promalina contribuiu para a melhoria da firmeza dos frutos armazenados em câmara fria, mas não produziu o mesmo efeito em frutos armazenados em temperatura ambiente. A atividade da enzima poligalacturonase (PG foi coincidente com a alteração de firmeza dos frutos, e o pH diminuiu.Considering the commercial value of the ‘Fuyu’ kaki, this study aimed to evaluate the effect of Promalin applied to the orchard as well as the use of different storage temperatures in the quality of postharvest fruits. The cold chamber (4ºC kept the fruit with good firmness quality for commercialization over 16 days, for both treatments, without and with Promalin applied in the orchard; whereas, at room temperature (20-26ºC the periods were 16 and 8 days, respectively. The Promalin contributed to the improvement of firmness in fruits stored in the cold chamber, but it did not have a similar effect in fruits at room temperature. The activity of the polygalacturonase enzyme was coincident with the change in fruitfirmness and the pH decreased.

    In this study, the anti-tumour-promoting and thermal-induced protein denaturation inhibitory activities of β-sitosterol (1) and lupeol (2), isolated from Diospyros lotus L., were explored. Compound 1 showed a marked concentration-dependent inhibition against 12-O-tetradecanoylphorbol-13-acetate (20 ng/32 pmol)-induced Epstein-Barr virus early antigen activation in Raji cells with IC50 of 270 μg/ml, without significant toxicity (70% viability). Compound 2 showed significant anti-tumour-promoting effect with IC50 of 412 μg/ml, without significant toxicity (60% viability). In heat-induced protein denaturation assay, compound 1 exhibited a concentration-dependent attenuation with a maximum effect of 73.5% at 500 μg/ml with EC50 of 117 μg/ml, while compound 2 exhibited a maximum effect of 59.2% at 500 μg/ml with EC50 of 355 μg/ml. Moreover, in silico docking studies against the phosphoinositide 3-kinase enzyme also show the inhibitory potency of these compounds. In short, both the compounds exhibited a marked anti-tumour-promoting and potent inhibitory effect on thermal-induced protein denaturation. PMID:26134930

A evapotranspiração da cultura (ETc foi determinada experimentalmente por meio de lisímetros de drenagem e a umidade do solo foi medida através de sensores instalados a uma profundidade de 20 cm. O desempenho do modelo de Penman-Monteith foi comparado aos valores decendiais do balanço hídrico nos lisímetros; já a evapotranspiração de referência foi calculada com dados externos e utilizada para o cálculo do Kc da cultura; enfim, os resultados indicaram que o modelo de Penman-Monteith subestima os valores de evapotranspiração encontrados pelo balanço hídrico nos lisímetros.The aerodynamic parameters of a crop cultivated in greenhouse can be considered dependent upon the level of global radiation, air temperature and relative humidity, based on exponential laws. Consequently, this work intends to estimate the evapotranspiration and the crop coefficient of Kaki tomato in greenhouse, under drip irrigation, using the Penman-Monteith model. The aerodynamic parameters were measured with sensors connected to the automatic station installed inside the greenhouse. The ETc was determined experimentally through drainage lysimeters and the soil water content was measured through sensors installed at a depth of 20 cm.

    Judicious and regulated use of wood as a building material is better than that of many other conventional materials in terms of environmental issues of this century. The study of the behavior of wood requires a better understanding of the characteristics in different possible cases of loading including loads applied instantly, loads applied for a short time and loads applied for a long time. The purpose of this study is to evaluate the influence of the loading duration on the linear viscoelastic parameters of tropical wood in creep test. Creep tests conducted on two species of tropical wood, Tectona grandis L.f and Diospyros mespiliformis, were carried out for a total loading duration of 15 hours by subjecting samples to bending test through with equal strain in all sections. After measuring the instantaneous deflection, the other measurements were carried out at regular time each 30 minutes. Each recorded deflection was converted into longitudinal deformation and the data were analyzed by considering fourteen loading durations. Using the least squares method, the dynamic modulus of elasticity and the modulus of dynamic viscosity were determined for each loading time. The results showed that the loading time has no influence on the modulus of dynamic viscosity. On the other hand, the dynamic modulus of elasticity decreases and tends towards zero. Good agreement between creep test data and dynamic modulus of elasticity was found using mathematical function in power. Suitably, the "power" function established between the elastic dynamic modulus and the loading duration can be used to extrapolate deformations values. PMID:24567881

    This paper presents the advances made over the last decade in cryopreservation of economically important vegetatively propagated fruit trees. Cryopreservation protocols have been established using both dormant buds sampled on field-grown plants and shoot tips sampled on in vitro plantlets. In the case of dormant buds, scions are partially dehydrated by storage at -5 °C, and then cooled slowly to -30 °C using low cooling rates (c.a. 1 °C/h) before immersion in liquid nitrogen. After slow rewarming and rehydration of samples, regrowth takes place either through grafting of buds on rootstocks or excision of apices and inoculation in vitro. In the case of shoot tips of in vitro plantlets, the cryopreservation techniques employed are the following: controlled rate cooling procedures involving slow prefreezing followed by immersion in liquid nitrogen or vitrification-based procedures including encapsulation-dehydration, vitrification, encapsulation-vitrification and droplet-vitrification. The current status of cryopreservation for a series of fruit tree species including Actinidia, Diospyros, Malus, Olea, Prunus, Pyrus and Vitis is presented. Routine application of cryopreservation for long-term germplasm storage in genebanks is currently limited to apple and pear, for which large cryopreserved collections have been established at NCGRP, Fort Collins (USA), using dormant buds and in vitro shoot tips, respectively. However, there are a growing number of examples of pilot scale testing experiments under way for different species in various countries. Progress in the further development and application of cryopreservation techniques will be made through a better understanding of the mechanisms involved in the induction of tolerance to dehydration and cryopreservation in frozen explants.

    Diospyros lotus is traditionally used for the treatment of diabetes, diarrhea, tumor, and hypertension. The purpose of this study was to investigate the anti-inflammatory effect and underlying molecular mechanisms of myricetin in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Myricetin dose-dependently suppressed the production of pro-inflammatory mediators (NO, iNOS, PGE2, and COX-2) in LPS-stimulated RAW264.7 macrophages. Myricetin administration decreased the production of NO, iNOS, TNF-α, IL-6, and IL-12 in mice. Myricetin decreased NF-κB activation by suppressing the degradation of IκBα, nuclear translocation of p65 subunit of NF-κB, and NF-κB DNA binding activity in LPS-stimulated RAW264.7 macrophages. Moreover, myricetin attenuated the phosphorylation of STAT1 and the production of IFN-β in LPS-stimulated RAW264.7 macrophages. Furthermore, myricetin induced the expression of HO-1 through Nrf2 translocation. In conclusion, these results suggest that myricetin inhibits the production of pro-inflammatory mediators through the suppression of NF-κB and STAT1 activation and induction of Nrf2-mediated HO-1 expression in LPS-stimulated RAW264.7 macrophages.

    The explants of Diospyros vaki is easy to occur browning during tissue culture process. In order to prevent browning, explants should be treated by heat shock before cultivation. Phenols content and activities of PAL, PPO and POD in D. vaki c.v. ‘Baohuatianshi’ leaves were researched, and physiological mechanism of heat shock treatment preventing browning was discussed. The results showed that browning degree of leaves was decreased significantly after heat shock treating, and total phenol content and activities of PAL and PPO were also lower than the control. But preventing effect of hot shock treatment on POD activity was not obvious. It suggested that heat shock treatment could inhibit synthesis and oxidation of phenols, and decreased quinones content, which was browning production, through reducing activities of PAL and PPO in explants. So heat shock treatment could effectively prevent browning.%甜柿在组织培养过程中极易褐化,为了防止褐变,在培养之前应对外植体进行热激处理。文中研究了热激处理后的宝华甜柿叶片在培养过程中其酚类物质含量和苯丙氨酸解氨酶(PAL)、多酚氧化酶(PPO)、过氧化物酶(POD)活性的变化情况,并对热激处理抑制组培褐变的生理机制进行了初步探讨。结果表明:热激处理后,宝华甜柿叶片的褐变程度比没有处理的明显减轻,其总酚含量与苯丙氨酸解氨酶(PAL)及多酚氧化酶(PPO)活性均有所降低,但热激处理对其过氧化物酶(POD)活性的抑制效果并不明显,说明热激处理通过降低外植体的PAL及PPO活性,抑制酚类物质的合成及氧化,减少了褐变产物——醌类物质的形成,从而有效抑制了褐变现象的发生。

  11. Concentration change of radiocaesium in persimmon leaves and fruits. Observation results in 2011 Spring - 2013 Summer

    International Nuclear Information System (INIS)

    To make dried-fruits of persimmon (Diospyros kaki), its fresh fruits were generally processed to decrease their water-contents to about 30-50%. During this food process, their radiocaesium concentrations increased without any loss, and, occasionally, the dried-fruits may exceed the food standard level of 100 Bq/kg (edible form). Thus, it is necessary to estimate the radiocaesium concentrations in the products before the fresh fruit harvesting and processing. For this purpose, radiocaesium concentrations in leaves of persimmon trees were monitored with time. The 137Cs concentrations in the fruits were usually lower than those in the leaves and the concentration ratio was less than 0.4 on a fresh weight basis. The ratio became smaller when closer the harvest season. Thus the concentration of leaves could be a good indicator to estimate the processed persimmon fruits. (author)

(CO) and roots of Glycyrrhiza glabra (GG) were investigated. The antimutagenic effects of compounds separately as well as their action in complex mixtures were studied on mutations induced by genotoxicants (X-rays, N-methylnitrosourea, cyclophosphamide, NaF) and aging in bone marrow cell chromosomes from mice and rats. When tested separately and in a complex mixture, the plant products showed an ability to decrease the frequency of chromosome aberrations. The antimutagenic properties of the complex mixtures were considerably greater than those of the separate components. More antimutagenic activity of the mixture was revealed when mutagenesis was the result of X-rays and the natural aging processes. PMID:12570329

    2002-01-01

    Cytological mechanisms of 2n pollen formation in ‘Zenjimaru' nonastringent persimmon (Diospyros kaki L.f. ) were studied. The following abnormalities in meiosis were found to be responsible for the production of 2n pollens: (1) disoriented spindles, including parallel, fused and tripolar spindles, were formed at metaphase Ⅱ and anaphase Ⅱ; (2) the nuclei at telophase Ⅱ were arranged to two poles, each of which contained two nuclei, or to three poles, one of which contained two nuclei, the other two contained one nucleus respectively; (3) dyads and triads were produced at the tetrad stage. The dyad would develop into two 2n pollens, and the triad would develop into one 2n and two n pollens. The 2n pollens produced by this mechanism were genetically equivalent to FDR (first division restitution) gametes, thus providing a potential value for sexual polyploidization.

Nesse particular, pode-se aquilatar a dificuldade para o melhorista realizar tais testes, pois um grupo de caquis taninosos mascara o paladar de duas ou três amostras subseqüentes. Daí a necessidade de desenvolver um processo de análise indireta, a exemplo do presente, que consiste no tratamento da polpa dos frutos com a solução de cloreto férrico. A reação de coloração "achocolatada", em diferentes tonalidades, indica o grau de tanino que encerra, permitindo efetuar a tipificação preliminar dos caquis, sem a necessidade de degustação.In IAC persimmon breeding program there is usually the need of analyzing hundreds of fruit samples coming from different hybrid plants, aiming at the selection of the best genetic materials. Fruits are usually harvested unripe and classified as to the astringency level in tasting tests: constant "shibugaki", variable "shibugaki"/ "amagaki" and absence of astringency "amagaki". As misleading results have been obtained in tasting tests, an indirect procedure has been proposed to evaluate tannin levels in persimmon flesh. It is based on a color scale (dark blue/dark gray - astringent type; brown - variable astringency, and light gray-absence of astringency, detected after the application of 0.1 N iron chloride solution on persimmon flesh.

    Effects of basal mediums, hormones and their concentrations on the shoot regeneration from leaf of sweet persimmon (Diospyros kaki Thunb. Cv. Uenishiwase) were studied by orthogonal design trial. The result showed that modified Murashige and Skoog [MS (1/2 N)] was the most optimum for the regeneration and 1/2 MS was better than MS. Shoot percentage in the medium containing 4.0 mg L-1 ZT(zeatin) was much higher than that of other two concentrations, among which 2.0 mg L-1 ZT was much better than 1.0 mg L-1 ZT and shoot percentage in the concentration of 1.0 mg L-1 ZT was only 4%. There were no any beneficial effects when supplementing IAA in the medium. Shoot percentage and average shoots perexplantsweredramaticallydecreasedinthe 2.0 mg L-1 IAA. Data in the orthogonal trial indicated that ZT was the most effective factor in the shoot regenerating of Uenishwase persimmon and basal medium was important too, but IAAhad no any beneficial effects at all. In the orthogonal trial, the best result was achieved in MS (1/ 2 N) medium containing 4.0 mg L-1 ZT and 1.0 mg L-1 IAA, in which shoot percentage and average shoots per explants were 86% and 2.2, respectively.

    Various plant species of green belt in urban traffic area help to reduce air pollution and beautify the city environment. Those plant species growing healthily under long-term atmospheric pollution environment are considered to be resilient. This study aims to identify plant species that are more tolerant to air pollution from traffic and to give recommendations for future green belt development in urban areas. Leaf samples of 47 plant species were collected from two heavy traffic roadside sites and one suburban site in Beijing during summer 2014. Four parameters in leaves were separately measured including relative water content (RWC), total chlorophyll content (TCH), leaf-extract pH (pH), and ascorbic acid (AA). The air pollution tolerance index (APTI) method was adopted to assess plants' resistance ability based on the above four parameters. The tolerant levels of plant species were classified using two methods, one by comparing the APTI value of individual plant to the average of all species and another by using fixed APTI values as standards. Tolerant species were then selected based on combination results from both methods. The results showed that different tolerance orders of species has been found at the three sampling sites due to varied air pollution and other environmental conditions. In general, plant species Magnolia denudata, Diospyros kaki, Ailanthus altissima, Fraxinus chinensis and Rosa chinensis were identified as tolerant species to air pollution environment and recommend to be planted at various location of the city, especially at heavy traffic roadside.

    Bile acid-binding agents are known to lower blood cholesterol levels and have been clinically used for the treatment of hypercholesterolemia. We previously showed that tannin-rich fiber from young persimmon (Diospyros kaki) fruits had bile acid-binding properties. In this study, we performed a randomized, double-blind, placebo-controlled trial to investigate the hypocholesterolemic effects of tannin-rich fiber in humans. The subjects (n = 40, plasma total cholesterol levels 180-259 mg/dl) were divided into 3 groups and ingested cookie bars containing 0 g (placebo group, n = 14), 3 g (low-dose group, n = 13), or 5 g (high-dose group, n = 13) of tannin-rich fiber 3 times daily before meals for 12 weeks. Plasma total cholesterol levels decreased significantly in the low-dose (12 weeks, p < 0.005) and high-dose (6 weeks, p < 0.05; 12 weeks, p < 0.001) groups. In addition, plasma low-density lipoprotein cholesterol levels decreased significantly in the high-dose group (6 weeks, p < 0.05; 12 weeks, p < 0.001). These improvements were not accompanied by changes in plasma high-density lipoprotein cholesterol or plasma triglyceride levels. Our findings indicate that tannin-rich fiber from young persimmon fruits is a useful food material for treating hypercholesterolemia. PMID:23171573

    This study evaluated the effects of two Korean traditional plant extracts (Diospyros kaki THUNB. leaf; DK, and Nelumbo nucifera leaf; NN) on the fermentation, functional and sensory properties of herbal yogurts. Compared to control fermentation, all plant extracts increased acidification rate and reduced the time to complete fermentation (pH 4.5). Supplementation of plant extracts and storage time were found to influence the characteristics of the yogurts, contributing to increased viability of starter culture and phenolic compounds. In particular, the increase in the counts of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus was highest (2.95 and 1.14 Log CFU/mL respectively) in DK yogurt. Furthermore, supplementation of the plant extracts significantly influenced to increase the antioxidant activity and water holding capacity and to produce volatile compounds. The higher antioxidant activity and water holding capacity were observed in NN yogurt than DK yogurt. Moreover, all of the sensory characteristics were altered by the addition of plant extracts. Addition of plant extracts increased the scores related to flavor, taste, and texture from plain yogurt without a plant extract, as a result of volatile compounds analysis. Thus, the overall preference was increased by plant extracts. Consequently, supplementation of DK and NN extracts in yogurt enhanced the antioxidant activity and physical property, moreover increased the acceptability of yogurt. These findings demonstrate the possibility of using plant extracts as a functional ingredient in the manufacture of herbal yogurt. PMID:27499669

    Oriental persimmon (Diospyros kaki) originated in Eastern Asia, and many indigenous cultivars have been developed in China, Japan, and Korea. These cultivars are classified into four groups based on their natural astringency loss on the tree and seed formation: pollination-constant non-astringent (PCNA), pollination-variant non-astringent (PVNA), pollination-constant astringent (PCA), and pollination-variant astringent (PVA). PCNA is the most desirable type because the fruit can be eaten without any postharvest treatment; therefore, one of the goals of our persimmon breeding programs is to release superior PCNA cultivars. The PCNA genotype is recessive to the other three non-PCNA genotypes, and PCNA-type F1 offspring are obtained exclusively from crosses among PCNA genotypes. Moreover, the number of superior PCNA cross-parents have been limited. In the late 1980s, inbreeding depression became obvious, especially in terms of fruit size, tree vigor, and productivity. To mitigate the inbreeding, a backcross program using PCNA [(non-PCNA × PCNA) × PCNA] was started in 1990. This process, however, was inefficient because only 15% of the offspring were PCNA, and all offspring had to be grown to the fruiting stage. Therefore, molecular markers linked to the PCNA locus were developed for discriminating PCNA offspring. A molecular marker linked to Chinese PCNA has also been developed. PMID:27069391

    Full Text Available Dialeurodes citri (Hom. Aleyrodidae first invaded citrus orchards in the South Adriatic, near Dubrovnik, during 1977. Since the characteristics of the pest have not been studied in Croatia, this paper reviews its morphology, locations, host plant range and biology. Leaf samples, collected all over the Croatian coast and islands, were observed in the laboratory for purpose of creating a map with citrus whitefly locations, morphological description and a list of host plants. The pest biological cycle and population trend were investigated in the region of Split (May 1996-May 1998. The presence of citrus whitefly was confirmed in all citrus-growing areas of Croatia. The number of noted host plants was somewhat lower than in Mediterranean countries. Other than citrus, it also colonised and harmed laurustinus (Viburnum tinus Hemsl., persimmon (Diospyros kaki Thunb. and several plants of Oleaceae. The citrus whitefly had three generations on citrus per year. However, the part of larval population that belonged to second generation did not finish the post-embryonic development and it remained on the summer flush leaves and awaited the hibernation. The appearance of adults followed the appearance of young citrus growth. All development stages had three population peaks during vegetation period. The presence of young larval stages (L-1, L-2 was pronounced during the middle of June, August and October. The pest overwintered mainly as fourth instar larva. On deciduous persimmon trees it had two generations per year.

    The objective of this study was to determine the effect of the pre-storage 1-Methylcyclopropene (1-MCP) treatment on the physiology and quality of sweet persimmons (Diospyros kaki L. cv. Fuyou' and Diospyros kaki L. cv. Cilang') harvested at different stages of ripeness and stored at different temperatures. The treatments were conducted with the 1-MCP concentration of 0. 50 μL · L-1 or 1.0 μL o L-1 and the fruits stored under either room (approximately 20℃) or refrigerated temperature (approximately 5℃). The results showed that the shelf life of the fruits at Stage I Ripeness could be extended for 14 days stored at room temperature, or 21 days under refrigeration. The 0. 50 μL o L-1 1-MCP application kept the fruits, especially those in Stage I Ripeness, fresh in the duration of storage. And, the percentage of acceptable fruits was significantly higher than the control. By combining the low temperature and 0. 50 μL o L-1 1-MCP treatment, the textural softening and peel color change to red on the fruits were delayed. The soluble sugar conversion, soluble tannin content, respiration rate, as well as the activities of PG and Cx in the fruits were also reduced. The results suggested that the sweet persimmons at Stage I Ripeness had a better potential than at Stage II Ripeness for an extended shelf life, and that the low temperature and 0. 50 μL o L-1 1-MCP treatment could postpone the ripening, and thus, the changes on the fruit' s texture and color.%为了探讨不同贮藏温度下1-MCP处理对不同成熟度的甜柿采后生理的影响.方法:以甜柿品种‘富有,、‘次郎’为材料,分别在低温(5℃)和室温(20℃)的贮藏条件下研究不同浓度(0.50 μL·L-1和1.00 μL·L-1)1-MCP(1-甲基环丙烯)处理对不同成熟度(成熟度Ⅰ与成熟度Ⅱ)甜柿好果率、硬度和若干生理指标的影响.结果表明,在贮藏期间,成熟度Ⅰ果实在室温下贮藏时间可延长14 d,低温下贮藏可延长21 d;0.50 μL·L-1 1

    Full Text Available Apenas na Ásia, centro de origem do caqui (Diospyros kaki L., existem mais de 2000 cultivares diferentes, das quais, a maioria é adstringente. Diante de tamanha variabilidade, existem diferentes métodos de remoção de adstringência, de tal forma que cada um deve ser adaptado a cada cultivar e local de produção. Tais métodos de destanização objetivam promover um acúmulo de acetaldeído na polpa dos frutos, o qual provoca a polimerização das moléculas de taninos solúveis, responsáveis pela adstringência, transformando-os num composto com consistência de gel, insolúvel e, assim, não adstringente. Entre os métodos mais utilizados estão: aplicação de vapor de álcool etílico, que ativa a enzima álcool dehidrogenase com subseqüente acúmulo de acetaldeído, e a promoção da anaerobiose, que induz a transformação do piruvato em acetaldeído em uma reação catalisada pela enzima piruvato descarboxilase. Neste trabalho de revisão, visa à discussão dos principais fatores a serem observados no processo de remoção da adstringência de caquis, como o método a ser utilizado, a temperatura de destanização, o tempo de exposição ao tratamento e o ponto de maturação dos frutos, entre outros.In Asia, the center of origin of persimmon (Diospyros kaki L., more than 2000 different varieties are present, most of then being astringent. Beyond such variability, there are a lot of different methods to remove the astringency of fruit and each treatment is more approachable for each cultivar and local of production. The different methods to remove the astringency are based, mostly, at the accumulation of acetaldehyde at the flesh fruit that induce the polymerization of the soluble tannin molecules, responsible for the astringency formation, turning them into an insoluble and non astringent substance. The most used methods are: ethanol vapor application which activates alcohol dehydrogenase and increases the acetaldehyde

    Unlike the typical climacteric fruits,persimmons (Diospyros kaki Thunb.) produce higher levels of ethylene when they are detached from trees at a younger stage.In order to obtain detailed information on the role of abscisic acid (ABA) in ripening,we cloned the DKNCED1,DKACS2,and DKAC01 genes from the calyx.Water loss was first noted in the calyx lobe,and DKNCED1 was highly expressed 1 d after the fruits were detached,coinciding with an increase in the ABA content.Then,the DKACS2 and DKAC01 genes were expressed after some delay.In the calyx,the ABA peak was observed 2 d after the fruits were harvested,and this peak preceded the ethylene peak observed on day 3.The fruit firmness rapidly decreased on day 4,and the fruits softened completely 6 d after they were harvested.The increases in the expressions of ABA,ethylene,and the genes in the calyxes occurred earlier than the corresponding increases in the pulp,although the 3 increases occurred on different days.Exogenous ABA treatment increased ABA concentration,induced expression of both ACS and ACO,and promoted ethylene synthesis and young-fruit softening;by contrast,treatment with NDGA inhibited the gene expressions and ethylene synthesis and delayed young-fruit softening.These results indicate that ethylene biosynthesis in the detached young persimmon fruits is initially triggered by ABA,which is induced by water loss in the calyx,through the induction of DKACS2 and DKAC01 expressions.The ethylene produced in the calyx subsequently diffuses into the pulp tissue,where it induces autocatalytic ethylene biosynthesis,resulting in an abrupt increase in ethylene production.

    Wild or commercially grown, native and exotic fruit were collected in 30 localities in the Tucumán province (NW Argentina) from January 1990 to December 1995 to determine their status as hosts of Anastrepha fraterculus (Wiedemann) and/or Ceratitis capitata (Wiedemann), the only two fruit fly species of economic and quarantine importance in Argentina. A total of 84,094 fruit (3,466.1 kg) representing 33 species (7 native and 26 exotic) in 15 plant families were sampled. We determined the following 17 host plant associations: Annona cherimola Miller (Annonaceae), Citrus paradisi Macfadyn (Rutaceae), Diospyros kaki L. (Ebenaceae), Eugenia uniflora L., Psidium guajava L., Myrcianthes pungens (Berg) Legrand (Myrtaceae), Ficus carica L. (Moraceae), Juglans australis Grisebach (Juglandaceae), Mangifera indica L. (Anacardiaceae), Eriobotrya japonica (Thunb.) Lindl., Prunus armeniaca L., P. domestica L., and P. persica (L.) Batsch (Rosaceae) were infested by both A. fraterculus and C. capitata. Citrus aurantium L., Citrus reticulata Blanco, Citrus sinensis (L.) Osbeck (Rutaceae), and Passiflora caerulea L. (Passifloraceae) were only infested by Ceratitis capitata. Out of a total of 99,627 adults that emerged from pupae, 69,180 (approximately 69.5%) were Anastrepha fraterculus, 30,138 (approximately 30.2%) were C. capitata, and 309 (approximately 0.3%) were an unidentified Anastrepha species. Anastrepha fraterculus predominated in native plant species while C. capitata did so in introduced species. Infestation rates (number of larvae/kg of fruit) varied sharply from year to year and between host plant species (overall there was a significant negative correlation between fruit size and infestation level).

    Full Text Available Illegal rosewood logging has known a strong increase in 2009, following two inter-ministerial texts legalizing exports of precious wood. National parks are specifically affected by this exploitation. It is of course very difficult to know the real situation concerning exploitation but also exports. This paper presents and discusses information about “illegal” exports. Firstly, after a recall of the legal context, it underlines the difficulties in collecting information. Several reasons are underlined: the size of container, the density of wood, the diversity of material (log, board, etc, the place of shipment, the filling up of containers, and under-declaration for fiscal reasons. Nevertheless, even if exports estimations are probably far from the reality, the equivalent of around 1,202 containers, representing a value of more than US$ 220,000,000 are listed. Secondly, it analyzes also traffic regulation systems. More specifically, it proposes a parallel between the regulation of ivory traffic and the regulation of precious wood traffic in Madagascar. It concludes that the process of garnishment with resale by auction has very few chances to be efficient. The ivory case shows that reinforcing processes of garnishment do not succeed in stopping the traffic. It rather provokes reorganizations of the value chain. In the long term, the sole solution will be the development of a sustainable labeled chain for precious wood. European Union Due Diligence Regulation and Lacey Act in United States participate in the strengthening of control on precious wood.

    Radiocesium ({sup 137}Cs) concentrations in persimmon tree tissues collected at Chiba, about 220 km south from Fukushima Daiichi nuclear power plant (FDNPP), were measured to obtain half-life of radiocesium in the trees. Persimmon (Diospyros kaki) is a deciduous tree and bears edible fruits in autumn. There were no leaves when the sampling area was received the radioactive fallout in March 2011 due to the FDNPP accident; the amount of {sup 137}Cs radioactivity in this area was ca. 13 kBq/m{sup 3} Both {sup 137}Cs and {sup 134}Cs were found in the newly emerged shoots of the persimmon trees collected at 26 April 2011 mainly due to foliar uptake. The concentrations were 1.1 kBq/kg-dry for {sup 137}Cs and 1.3 kBq/kg-dry for {sup 134}Cs. After that, continuous sampling of leaves, branches and fruits of the persimmon trees had been carried out for two years. Immediately after the collection, samples were transferred to our laboratory and weighed to obtain fresh weight. Leaf samples were usually separated into two portions; one portion was washed with tap water to remove dust from the surface and the other portion was not treated. For fruit samples, if it is possible, fruit flesh, peal and non-edible part were separated. All the samples were oven-dried at 80 deg. C for three days at least. Each dried sample was chopped into fine pieces, mixed well, and then transferred into plastic vessels separately. Radioactivity concentration was measured by a Ge-detecting system (Seiko EG and G Ortec) using 3000-40000 s counting intervals. By August 14, 2013, about 140 samples were collected from the trees; about 60 samples were leaves (both washed and untreated). Radiocesium concentrations in tree leaves decreased with time, and the effective half-life was about 190 d; the value was similar to those in branches (160 d for new branches, and 250 d for 1-2 y.o. branches) and fruits (250 d for fruit flesh and 230 d for peals). Thus we concluded that the half-life of radiocesium in

    The number of winds sensed and the ratio of time sensing were introduced as sensory indexes and their relation with the comfort index in a natural ventilated room in summer was studied. A current of air is felt uncomfortable in an air conditioned room but it is felt especially comfortable in a natural-ventilated room in summer. A field investigation was made on the third floor of a building in Kyoto for 4 days in the beginning of September. The number of winds sensed in a certain time was counted and the ratio of time sensing to the certain time was measured. The wind sensed was reported dividing into 2 categories, i.e. 'wind sensing' and 'not sensing'. In this paper, the environment and temperature distribution in the room and the appropriateness of the wind sensing reports are discussed. Then the number of winds sensed and the ratio of time sensing are studied using the data obtained and it is concluded that they are effective as comfort indexes in a natural-ventilated room. 16 refs., 15 figs., 9 tabs.

    chloroplast genomes among the hybrids of the 38 fusion combinations,random segregation of chloroplast in Citrus fusion hybrids was further proved,and 1 : 1 segregation ratio were revealed in the fusion combinations of Kinnow tangerine+Jincheng Orange and Bonanza navel orange+Goutou sour orange,respectively.4) Sixty-four DNA samples belonging to 31 kinds of tropical and subtropical fruit crops were ampli-fiedwith the synthesized cpSSR primers,and a set of wide adaptable universal primers were screened. For instance,SPCC1 was rich in polymorphism among intergenera or interspecies,such as persimmon (Dto-spyros kaki ) and dateplum persimmon (Diospyros lotus),banana (Musa spp. ) ,guava (Psidium spp.), papaya (Carica spp. ) and grape (Vitis spp. ).8. Twenty-three genotypes of calli adequately representing the Citrus species and related genera were selected,and corresponding leaves were used as the control to analyze the stability of mitochondrial and chloroplast (plastome) genome. RFLPs,histological section, cpSSR and mtDNA transferring from the cytoplasm to the nuclei were analyzed. The results were as follows:Dlow frequency of mtDNA mutation existed in Citrus calli,while the mtDNA contents increased in individual mitochondria,and no such phenomena were observed in chloroplast genome.2) Analyzed with cpSSR, novel bands were detected among most of the calli. Both Southern hybridization and sequencing proved that the bands were amplified uniquely, suggesting that short sequences insertion occurred frequently in Citrus calli plastid genomes.3) Dot blotting analyses were performed by using nuclear DNA hybridized with mitochondrial probes. Results showed that mitochondrial DNA transfering from cytoplasm into nuclei occurred during long-term subculture.

    2007-05-15

    A new indirect growth model was used to predict the growth of 2 Mexican tree species in a climatic warming scenario. The growth trajectory of 30 Pinus hartwegii trees was modelled using radial increment data over a period of 102 years. The average growth pattern of 28 Pinus hartwegii trees were then modelled with radial increment data over a period of 37 years while considering average increments and temperature as important variables. Results showed that precipitation was significantly correlated with temperature. The average growth rate of 92 Diospyros digyna trees were then modelled with increment data over a period of 3 years with specific reference to circumference measurements, with temperature and precipitation as explaining variables. The piecewise linear (PL) model derived long-term age-diameter growth curves for trees without detectable annual growth rings through the use of species- and site-specific short term data. Multiple PL regression, statistical analyses and growth curve calculations were conducted. Growth curves were developed as a linear function of environmental variable including temperature and precipitation. The average of the annual increment over the measured years of the tree was then used as an index for nutrient availability, water access, and light exposure. The study showed that as a consequence of a 0.6 degree C temperature increase, the species Pinus hartwegii will decrease its expected growth by 10.6 per cent throughout its lifetime. The rainforest species Diospyros digyna will increase its expected relative growth by 25.4 per cent. It was concluded that increased carbon dioxide (CO{sub 2}) concentrations will also accelerate growth of the Diospyros digyna species. 63 refs., 6 figs.

    Full Text Available Pengamatan filariasis pada penduduk Nualolo-Lekebai, Pulau Flores telah dilakukan pada bulan Februari 1975. Kampung Nualolo-Lekebai berpenduduk 680 jiwa, pekerjaan bertani dan menganut agama Nasrani. Kebiasaan hidup di antara penduduk di daerah ini adalah menyerahkan pelaksanaan pekerjaan berat pada kaum wanita, baik di rumah ataupun di kebun. Dalam perjalanan jauh baik ke kebun atau ke pasar, kaum wanitanya selalu berjalan kaki sedangkan kaum prianya menunggang kuda. Sejumlah 80% dari penduduk kampung ini telah diperiksa terhadap infeksi parasit filaria dan terhadap gejala filariasis. Dari hasil yang ditemukan ternyata penduduk kampung ini menderita infeksi Brugia timori dengan angka derajat infeksi sebesar 7.0% dan angka derajat elephantiasis sebesar 10.3%. Hal yang menarik yang ditemukan dalam pengamatan ini adalah tingginya angka derajat elephantiasis pada kaum wanita dibandingkan dengan pada kaum pria. Fenomena ini mungkin disebabkan oleh kebiasaan hidup kaum wanita di daerah ini sehari-hari yang bekerja lebih berat dan berjalan kaki lebih sering dan lebih jauh dibandingkan kaum prianya.

    Full Text Available Este trabalho teve como objetivo levantar informações sobre os padrões de composição faunística, estrutura da comunidade e sazonalidade de Chrysomelidae num pomar localizado na região dos Campos Gerais do Paraná. Durante cerca de dois anos de amostragem, foram coletados 3.661 coleópteros e, destes, 1.103 crisomelídeos, representando 30,1% dos besouros capturados. Eumolpinae e Galerucinae foram as duas subfamílias que apresentaram maior abundância e riqueza de espécies, sendo que as oito mais representativas no pomar foram: Eumolpinae sp. 7 e Eumolpinae sp. 15, Diabrotica speciosa, Iphimeis dives, Spintherophyta semiaurata, Colaspis sp. 1 e Colaspis sp. 2 e Syphrea sp. 1, representando 91,7% dos indivíduos coletados. Em relação às árvores frutíferas, observou-se que o maior número de insetos foi coletado em laranjeira e tangerineira; a laranjeira teve a maior riqueza de espécies, e o caquizeiro apresentou o maior índice de diversidade. A redução considerável de crisomelídeos no segundo ciclo anual demonstra que a família tem uma oscilação temporal acentuada. A primavera foi a estação de maior abundância nos dois anos de coleta, e os fatores meteorológicos não apresentaram correlação com a abundância de crisomelídeos.

    Full Text Available Grewia occidentalis plants in the study area generally occurred in bush clumps with other shrub species. Grewia occidentalis commonly occurred with Diospyros austro-africana, Rhus longispina and Rhus pollens (nurse shrubs, but seldom with Acacia kar-roo and Lycium cinereum (non-nurse shrubs. Eland browsed G. occidentalis plants at higher levels than other shrub species, but browsing was not evenly spread across all plants. Grewia occidentalis plants associated with nurse shrubs had lower levels of browsing than those growing alone and those growing with non-nurse shrubs, while G. occidentalis plants in the centre of nurse shrubs experienced the lowest levels of browsing. The latter group of plants also produced the most fruit. Eland browsing is consid-ered an important factor determining the distribution of G. occidentalis plants in the study area, while the presence of nurse shrubs is considered essential for the establishment and maintenance of the G. occidentalis population in the study area.

    Full Text Available A plot of 150x700 m2 was established in a mixed dipterocarps of Wanariset Semboja, East Kalimantan during the periods of 1979-1981. The forest was dominated by Eusideroxylon zwageri (Lauraceae, Dipterocarpus cornutus (Dipterocarpaceae, Pholidocarpus majadum (Arecaceae, and Diospyros borneensis (Ebenaceae. Since the plot establishment, the forests then had experienced three times of forest fires, those were in 1982-1983, 1994-1995 and 1997-1998. The present paper reports the results of re-measurement of some 150x110 m2 parts of the plot in August 2003, about 23 years after plot establishment. Micro topographically, the studied plot was relatively undulating in higher parts and relatively flat in the lower parts of the plot, while the differences between lowest sub-plot and higher sub-plot of the re-measured plot was 26 m. Forest floor of the lower parts of the plot were humid to wet during rainy season and still humid during dry season. Almost all of the trees within lower parts of the plot were escaped from these three times of forest fires; hence these sub-plots were dominated by the trees of primary species that enumerated in 1980. Those sub-plots in the higher parts were burnt during the past forest fires indicated by the charcoal of standing trees and remaining felling logs in the forest floor. These burnt sub-plots were dominated by pioneer or secondary tree species, such as: Mallotus spp., Macaranga spp., Ficus spp. and Vernonia arborea. Local distribution of some indicator species (such as primary tree species: Pholidocarpus majadum, Diospyros spp., Eusideroxylon zwageri and species of Dipterocarpaceae; pioneer or secondary tree species Vernonia arborea, Macaranga spp., Mallotus spp., Ficus uncinulata, Piper aduncum, Peronema canescens within the plot were figured. Mortality, recruitment and growth rate during the period of 1980-2003 were also discussed.

    Challenges of resistance to synthetic antimicrobials have opened new vistas in the search for natural products. This article rigorously reviews plants and other natural products used in oral health: Punica granatum L. (pomegranate), Matricaria recutita L. (chamomile), Camellia sinensis (L.) Kuntze (green tea), chewing sticks made from Diospyros mespiliformis Hochst. ex A.D.C., Diospyros lycioides Desf., and Salvadora persica L. (miswak), honey and propolis from the manuka tree (Leptospermum scoparium J.R. Forst. & G. Forst.), rhein from Rheum rhabarbarum L. (rhubarb), dried fruits of Vitis vinifera L. (raisins), essential oils, probiotics and mushrooms. Further, the review highlights plants from Africa, Asia, Brazil, Mexico, Europe, and the Middle East. Some of the plants' antimicrobial properties and chemical principles have been elucidated. While the use of natural products for oral health is prominent in resource-poor settings, antimicrobial testing is mainly conducted in the following countries (in decreasing order of magnitude): India, South Africa, Brazil, Japan, France, Egypt, Iran, Mexico, Kenya, Switzerland, Nigeria, Australia, Uganda, and the United Kingdom. While the review exposes a dire gap for more studies on clinical efficacy and toxicity, the following emerging trend was noted: basic research on plants for oral health is mainly done in Brazil, Europe and Australia. Brazil, China, India and New Zealand generally conduct value addition of natural products for fortification of toothpastes. African countries focus on bioprospecting and primary production of raw plants and other natural products with antimicrobial efficacies. The Middle East and Egypt predominantly research on plants used as chewing sticks. More research and funding are needed in the field of natural products for oral health, especially in Africa where oral diseases are fuelled by human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS).

Sektor formal dianggap tidak mampu menyediakan kesempatan kerja untuk seluruh lapisan masyarakat, apalagi mereka yang ada pada posisi marjinal. Pada beberapa kasus-khususnya yang berhubungan dengan sektor informal perkotaan perlakuan dan kebijakan negara menjadi sangat diskriminatif karena seringkali berhadapan dengan kebijakan negara yang bahkan berakhir dengan kekerasan.  Perlindungan terhadap sektor informal salah satunya adalah pada pedagang kaki lima di Surakarta.  Kota ini menjadi contoh representatif dalam pengorganisasian kepentingan  pemerintah  dan pedagang kaki lima. Ini dapat menjadi inspirasi positif bagi penanganan sektor informal di tempat yang lain untuk memperluas lapangan kerja bagi masyarakat dan meningkatkan kesejahteraan sosial. As an alternative economic system, the existence of informal sector invites pros and cons. The significant role of informal sector as a safety valve of the national economy has not been matched by government with the protection or support The objective of this study is to discuss the role of the informal sector in addressing social and economic issues, and the dilemma faced by the informal sector in carrying out this role. The results of this study shows that there is an important role of the informal sector in the field of employment and unemployment absorption. The formal sector is not considered able to provide job opportunities to all levels of society

    Full Text Available My first experiences of Japan were so early in life that they are hazy in my memory. My neighbours in São Paulo City, a sprawling megalopolis in Brazil, were Japanese migrants. I was seven or eight when I first saw their festivals and performance presentations from my parents’ bedroom window. I remember my awe at their colourful costumes, masks and music. On a daily basis I remember the pungent smell of the soy sauce they produced in a factory in their backyard. We also shopped at a small neighbourhood supermarket called Shinohara. We bought paper and sticks for our kites from a general store owned by another Japanese migrant. We would tell our mother that we were going to ride our bikes to the ‘Japonesa’ to get kite material. At home, caqui (Japanese kaki was my favourite fruit, but we also had all sorts of vegetables the Japanese migrants brought from Japan. We even called Japanese pumpkin by its Japanese name – kabocha.

    Full Text Available This experiment was carried out during two successive seasons (2008-2009 and (2009-2010 on Costata persimmon fruits (Disopyros kaki, L harvested at mature stage. Experimental fruits were divided into five similar groups; each of three boxes and each box about 2 kg. Fruits of each group were emulsified in one of the following jojoba oil emulsion concentrations: 0, 25, 50, 75 and 100%. Treated fruits were stored at 13+1oC and 90% RH. Weight loss percentage, decayed fruits, changes in fruit weight loss, fruit firmness, flesh SSC, total sugars, acid and vitamin C were evaluated at 7 days intervals. Jojoba oil emulsifying reduced weight loss, decay fruit percentage. This beneficial effect was connected to oil emulsion concentrations; the high oil concentration recorded the lower weight loss and discarded fruit percentage. Jojoba oil treatments increased both fruit flesh firmness and acid content, since fruits treated with 100% concentration showed higher flesh firmness and flesh acid values than the lower tested oil concentrations. Fruits received oil at 75% concentration showed the lower total sugar content than those of the control. SSC of fruit was not much affected by all jojoba oil concentrations. All treatments improved shelf live compared with the control. The percentage of natural infection was increased with increasing storage period. In this concern, jojoba oil emulsion at 100% was the effective preserving natural compound.

    Full Text Available Study on the socio-cultural aspects in relation to filariasis transmission dynamics was carried out in the transmigration area of Kumpeh, Iambi. In this study a number of 266 respondents originated from Java were interviewed. Beside interview by using questionnaires, focus group discussions and observation were also implemented. From this study it was known that the word "filariasis" seemed to be unpopular among the transmigrants. They used to called the disease untut or penyakit kaki gajah. A great number of the respondents stated that the disease is transmitted through mosquito bites, but they did not know the mode of the transmission. A small number of the respondents were of the opinion that the disease was hereditary and this knowledge was adopted from the local inhabitants. The attitude of the respondents towards filariasis control measures was positive, and it was shown among others, by their willingness to be bled for filariasis examination. Their behaviour in its connection with filariasis transmission was not supportive towards filariasis control e.g. they used to stay in the ladang, and chat outdoor during the night without protection against mosquito bites. From this study it was also known that they exposed themselves to the mosquito bites mainly in the ladang when they take guard of their crops from pests damages. Their low education affected their perception towards filariasis and will hamper health education on filariasis control.

    Fossils from the Cambrian to Devonian rocks of southern Thailand, the Langkawi Islands, mainland Kedah, Perlis, north Perak and central West Peninsular Malaysia are listed and reviewed, and their stratigraphy and correlation reassessed. The hitherto anomalous record of the trilobite Dalmanitina from Malaysia is reviewed and found to be of latest Ordovician (Hirnantian) age, rather than Lower Silurian age as previously reported, and is considered a probable synonym of the widespread Mucronaspis mucronata. A new stratigraphical nomenclature is erected for part of the Langkawi, mainland Kedah and Perlis area successions, in which the term Setul Limestone (which stretched from the Ordovician to the Devonian) is abandoned and replaced by the Middle Ordovician Kaki Bukit Limestone, the late Ordovician and early Silurian Tanjong Dendang Formation, the Silurian Mempelam Limestone, and the early Devonian Timah Tasoh Formation, all underlying the paraconformity with the late Devonian Langgun Red Beds. There was a single depositional basin in the generally shallow-water and cratonic areas of southern Thailand, Langkawi, and mainland Kedah and Perlis, in contrast to the deeper-water basin of north Perak. Only Silurian rocks are dated with certainty within another basin in central West Malaysia, near Kuala Lumpur, which were also cratonic and shallow-water, although to the east in west Pahang there are basal Devonian deeper-water sediments with graptolites. The area is reviewed in its position within the Sibumasu Terrane, which, in the Palaeozoic, also included central and northern Thailand, Burma (Myanmar) and southwest China (part of Yunnan Province).

    We investigated the hypolipidemic effects of young persimmon fruit (YP) on apolipoprotein E-deficient C57BL/6.KOR-ApoEshl mice. These mice exhibited higher plasma cholesterols, except for high-density lipoprotein (HDL), and lower plasma HDL cholesterol than C57BL/6.Cr mice that had the same genetic background as the C57BL/6.KOR-ApoEshl mice. Male C57BL/6.KOR-ApoEshl mice (n=5) were fed a diet supplemented with dry YP, Hachiya-kaki, at a concentration of 5% (w/w) for 10 weeks. YP treatment significantly lowered plasma chylomicron, very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) cholesterols, and triglyceride, and this response was accompanied by an elevation of fecal bile acid excretion. In the liver, sterol regulatory element binding protein-2 gene expression was significantly higher in mice fed YP, while the mRNA and protein levels of the LDL receptor did not change. These results indicate that acceleration of fecal bile acid excretion is a major mechanism of the hypolipidemic effect induced by YP in C57BL/6.KOR-ApoEshl mice. PMID:18838807

  1. Studies on the effect of environmental conditions and gamma rays on the capability of certain plant pathogenic fungi to produce the enzyme degrading tannic acid

    International Nuclear Information System (INIS)

    Tannins (polyphenols and catechins) are distributed in species throughout the plant kingdom. They are commonly found in both gymnosperms as well as angiosperms. Histologically tannins are mainly physically located in the vacuoles or surface wax of plants. These storage sites keep tannins active against plant predators. Tannins themselves are found principally in the bark, leaves and immature fruits of a wide range of plants. They form complexes with proteins and other plant polymers such as polysaccharides. It is thought that the role of tannins in nature is one of the plant defense mechanisms. They have an astringent, aversive taste that is off-putting to wannabe herbivores. As an animal or insect begins to munch on plant tissues, the tannins are released from cellular compartments and bind with the proteins and other cell components, making them taste unpleasant and rather indigestible. Tannins are found in many foods and drinks such as tea plant, pomegranates, persimmons (kaki), berries (especially cranberries, strawberries and blueberries), nuts (especially hazelnuts, walnuts and pecans), beer, herbs and spices (especially cloves, tarragon, cumin, thyme, vanilla and cinnamon), legumes (especially red colored beans) and chocolate (6% tannins). It is worth to mention that apple juices, grape juices and berry juices are all high in tannins. Sometimes tannins are even added to juices to create a more astringent feel to the taste

    Full Text Available Any variationist study of Ivory Coast French needs to take into account sociolinguistic considerations and systemic features of other contact languages. For instance, there is a specific usage of pour against which the interference hypothesis can easily be tested:FI: Le kaki que je porte présentement, c'est pour un bachelier qui me l'a laissé avant de partir en fac, cadeau. (Lafage 2003: 676. Avant de te moquer du linge de ta voisine, regarde si pour toi est propre..In Ivory Coast French, pour (N/Pro can display a variety of functions: it can be part of associative predications, it can stand for genitive phrases in an anaphoric construction, make reference to an object in relation with another and participate in various idiomatic expressions.This paper has a twofold objective. First, I argue that pour (N/Pro constructions has to be analysed as an empty headed "associative" noun phrase. Second, I will show the relevance of extra- AND intersystemic factors in accounting for language variation. Incidentally, the use of pour (N/Pro constructions seems to be conditioned by the availability of similar constructions in other Ivory Coast languages on the one hand, such as baoule (o liε or dioula (à tá, and, cultural needs on the other.

    1985-05-01

    Forty-one patients were operated upon for acute intestinal obstruction secondary to the presence of phytobezoars, 34 of these patients (83%) having a history of previous gastric surgery for ulcer. The etiologic factor in 44% of cases was oranges and in 56% persimmons (Kakis). Treatment was by enterotomy in 27 patients (65,85%) and by "milking" in 14 (34,15%). Postoperative mortality was 2,44% (1 case). Recurrence was noted in three cases (7,3%) including one with an ileocutaneous fistula, treatment being by enterotomy in 2 cases and "milking" in the third patient. First intention intestinal resection was never required. Five patients required several admissions for subacute obstruction treated conservatively. These findings suggest that gastric surgery predisposes to intestinal obstruction by phytobezoar. Careful exploration of the digestive tube and particularly the stomach should avoid postoperative relapse, while prevention depends on a dietary regimen avoiding excessive intake of foods rich in cellulose, particularly oranges and persimmon fruit.

    Methanol extracts of seven edible fruits found in southern Brazil: Garcinia achachairu, Rubus imperialis, Rubus rosaefolius, Solanum quitoense, Solanum sessiliflorun, Diospyros inconstans and Plinia glomerata, were evaluated for their total phenol content and antioxidant activity in different in vitro free radical scavenging models. In addition, studies were performed on cell viability of extracts of the seeds of G. achachairu against murine melanoma cells. The fruits peel and seeds of G. achachairu were very promising in terms of total phenol content (data in gallic acid equivalent per gram), as assessed by the Folin-Ciocalteu method, with values of 9.70±3.2 and 8.40±1.1, respectively. On the other hand, antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl scavenging assay showed that the fruit pulp and peel of P. glomerata presented the best profile, with values of the 16.3±1.8 and 15.9±2.4 μg/ml, respectively. Regarding the cytotoxic effect of methanol extract and guttiferone A from G. achachairu, we have observed that both inhibit the growth of B16F10 tumor cells, with calculated IC50 values of 49.6±2.1 mg/ml and 48.6±5.4 mM, respectively.

    Despite the common occurrence of ringtails (Bassariscus astutus) few studies have been conducted to assess population characteristics. The objectives of this study were to determine (1) habitat selection, (2) home range, (3) denning characteristics, and (4) food habits of ringtails in the Trans Pecos region of west Texas. Seventeen ringtails were captured between November 1999 and January 2001 using Havahart live box traps. Second- and third-order habitat selection was determined for a ringtail population using range sites, slope, elevation, and vegetation communities. Diets were determined from volumetric scat analysis. The mean summer and winter range sizes (100% Minimum Convex Polygon [MCP]) for ringtails (n = 5) were 0.28 ?? 0.163 km2 and 0.63 ?? 0.219 km2, respectively. Overlap between ringtail ranges averaged 33.3%. Ringtails preferred catclaw (Mimosa biuncifera), persimmon (Diospyros texana), oak (Quercus sp.) bottom and catclaw/goldeneye (Viguiera stenoloba), sideoats (Bouteloua curtipendula) slope communities. Rock dens were used exclusively by ringtails, with 80.6% of dens found on slopes between 30-60%. Plant (seeds and miscellaneous vegetation) and animal material were found in 74.6 and 86.6% of scats, respectively. Findings suggest that ringtails in Trans Pecos, Texas, are an important component of the ecosystem and that management practices should conserve canyon habitats and adjacent slopes for ringtails.

    Full Text Available Repeated slash and burn cultivation creates wasteland with thorny shrubs, which then takes a long time to become secondary forests through serial stages of succession. Assisted natural regeneration through silvicultural management is a useful restoration method to accelerate succession. This survey evaluates the effectiveness of a simple silvicultural method for the rehabilitation of degraded lands to productive forest, thereby increasing floristic wealth. Field-based comparative analyses of floristic composition were carried out at a silviculturally managed forest (Popham Arboretum and a primary forest (Kaludiyapokuna Forest Reserve which is located in Dambulla in Sri Lanka. Floristic analysis was used to examine the effectiveness of silvicultural techniques for successful restoration of degraded forest in the dry zone. Nine 20 m × 20 m plots in each forest were enumerated and the vegetation ≥ 10 cm girth at breast height was quantitatively analyzed. Cluster analysis resulted in five distinguishable clusters (two from Popham Arboretum and three from Kaludiyapokuna Forest Reserve. Similarity indices were generated to compare the plots within and between sites. Floristic similarity was higher in forest reserve plots compared to arboretum plots. A total of 72 plant species belonging to 60 genera and 26 families were recorded from the study sites. Of the recorded species, Grewia damine and Syzygium cumini (Importance Value Index, IVI = 24 and 23 respectively were the ecologically co-dominant taxa at the Popham Arboretum. In contrast, Mischodon zeylanicus (IVI = 31, Schleichera oleosa (IVI = 25 and Diospyros ebenum (IVI = 21 were the abundant taxa in the forest reserve.

    Full Text Available Waste Tendu (Diospyros melanoxylon leaves from bidi (local cigarette industry has been used as a raw material to produce activated carbon applying sulfuric acid carbonization method. Batch experiments were conducted to assess the potential for the removal of methylene blue dye from aqueous solution using the activated carbon and compared to raw tendu leaves powder and commercial activated carbon. Equilibrium isotherm and kinetic studies have been done by varying the parameters such initial concentration of dye, adsorbent dose, pH of the dye solution, and varying the contact time between the carbon and the dye. It was found that the methylene blue adsorption on tendu waste-based activated carbon conformed to the Langmuir isotherm. The maximum monolayer adsorption capacities were found to be 219.3, 355.9 and 495.1 mg/g for raw tendu waste, carbonized tendu and commercial carbon, respectively. The kinetic studies were well characterized by a pseudo second order kinetic model. The results of this study indicate that raw tendu waste a renewable bioresource, as such as well as its carbonized form are attractive biosorbent for removing a cationic dye from the dye wastewater.DOI: http://dx.doi.org/10.5755/j01.erem.63.1.2735

    Full Text Available The major plant communities of the Karoo National Park are described using the methods of the Zurich-Montpellier school of phytosociology, to assist with the formulation of a management strategy for the park. The vegetation physiognomy consists of Montane Karoo grassy shrublands. Karoo grassy dwarf shrublands. Karoo succulent dwarf shrublands and riparian thicket. Steep elevation and precipitation gradients within the study area have a direct impact on gradients in the vegetation. High elevation (1 800 m, and relatively high rainfall (406 mm montane grasslands occupy communities dominated by grasses (Merxmuellera disticha, Themeda triandra and woody species (Diospyros austro-africana, Elytropappus rhinocerotis, Euryops annae, Passerina montana. The increasing aridity away from the escarpment edge in a northerly direction is steep, and Montane Karoo dwarf shrublands replace these mesic communities. Species such as Eriocephalus ericoides, Rosenia oppositifolia and Pteronia tricephala dominate. At lower elevation (800 m the precipitation is very low (175 mm and uncertain (coefficient of variation of 78 . The substrata influence the vegetation, with the sandy substrata of the drainage lines supporting more woody taxa (Acacia karroo, Lycium cinereum and grasses (Hyparrhenia hirta, Stipagrostis namaquensis, Cenchrus ciliaris. Moving away from the mesic environment of the riparian zone, rapid desiccation occurs and the most xeric communities are encountered, dominated by Stipagrostis obtusa, S. ciliata and Pent-da incana. This document provides descriptions of the general communities and their associated landscape, lithology and soils.

    Full Text Available Rapid urbanization will be critical to urban environments. The immediate and most critical urban environment problems facing several big cities, such as Jakarta and Surabaya, what are referred to as the "brown" problems, among them: lack of safe water, pollution from vehicles and industrial facilities, and congestion. To cope with these urban environmental problems, New Urbanism through the Traditional Neighborhood Development (TND believes that it will cure the problems by pedestrian oriented planning, encouraging people to drive less, mixed land uses, higher density, then traffice congestion is reduced,and mitigate air pollution. Moreover, the other physical and social characters are mixed housing types, front porches, more park that will encourage more interaction, then restore a sense of community. Based on this concept, this paper discusses the physical and social characters of real estates in Jakarta and Surabaya. The results show that real estate developments in these suburban areas is one of the causes of urban environment problems. Abstract in Bahasa Indonesia : Cepatnya urbanisasi akan menyebabkan lingkungan perkotaan yang kritis. Masalah lingkungan kritis yang dihadapi oleh kota-kota besar seperti Jakarta dan Surabaya adalah apa yang disebut dengan masalah "warna coklat" yaitu kurangnya air yang sehat, polusi udara yang berasal dari kendaraan bermotor dan industri, serta kemacetan lalu lintas. Untuk menyelesaikan masalah lingkungan ini, gerakan New Urbanism melalui konsep Traditional Neighborhood Development (TND percaya bahwa masalah lingkungan ini dapat diatasi dengan perencanaan permukiman yang berorientasi pada pejalan kaki, multi fungsi, kepadatan tinggi, sehingga mengurangi kendaraan bermotor dan berakibat pada berkurangnya kemacetan lalu lintas dan polusi udara. Karakter fisik dan sosial lainnya adalah multi tipe rumah, taman publik yang lebih banyak dan rumah berteras depan yang akan mendorong interaksi sosial dalam lingkungan

Melalui pendekatan etnomusikologi, tulisan ini menelaah peranan musik internal dan eksternal dalam kesenian Randai. Kesenian ini menggunakan medium seni ganda atau kolektif karena didukung oleh beberapa cabang seni antara lain tari, musik, teater, sastra, dan rupa. Hasil penelitian menunjukkan bahwa musik iringan dalam Randai terbagi menjadi dua, yaitu musik internal dan musik eksternal. Musik internal adalah musik atau bunyi-bunyian yang berasal dari anggota tubuh manusia (penari, misalnya tepukan tangan, petik jari, tepuk dada, siulan, hentakan kaki ke tanah dan sebagainya, sedangkan musik eksternal adalah bunyi-bunyian atau suara yang berasal dari alat musik atau instrumen seperti talempong, gandang, saluang, dan rabab. The Role of Internal and External Music in the Arts of Randai. The musical life in Minangkabau society is inseparable from its roles and functions which attach to the arts of Randai. Through the ethnomusicology approach, this paper examines the role of internal and external music in the art of Randai. Considering its sustainability and amendment, the musicality is the identity of Minangkabau society so that the sustainability of the music can be run in accordance with the dynamics of society today. Among the types of arts in Minangkabau, Randai is an art form that uses multiple or collective art medium for it is supported by several branches of the arts, including dance, music, theater arts, literary arts, and fine arts. The results of this study is more focused on the art of music. Musical accompaniment in Randai is divided into two, namely internal and external music. The internal music is the music or the sounds that come from the human body (a dancer, for example, clapping, finger picking, patting the chest, whistling, stomping on the ground, and so on, while the external music is the sounds emanating

    Full Text Available Em paisagens fragmentadas, a colonização por novas espécies em reflorestamentos e capoeiras é dificultada pelas grandes distâncias das fontes de propágulos e a alta degradação do solo. Neste contexto, o enriquecimento artificial de reflorestamentos com espécies nativas de níveis sucessionais mais avançados torna-se imprescindível para garantir a sustentabilidade do ecossistema. Métodos como a transferência de serapilheira e solo de florestas maduras e a semeadura direta podem ser alternativas. Amostras de serapilheira e solo foram distribuídas em duas áreas de reflorestamento e uma área-controle, e nove espécies nativas não-pioneiras foram semeadas diretamente nas mesmas áreas e em dois controles. Da serapilheira, germinaram 14 espécies no controle: sete arbóreas, três herbáceas, duas lianescentes e duas arbustivas. As árvores são na maioria pioneiras e, portanto, de interesse limitado para o enriquecimento. Entretanto, as espécies não-arbóreas, importantes na diversidade de ecossistemas florestais, representaram metade dos indivíduos catalogados. Na semeadura direta, a espécie mais interessante foi Diospyros brasiliensis, com taxas de germinação de 50%. Achatocarpus pubescens e Cordia ecalyculata apresentaram resultados expressivos, apesar de heterogêneos. Os resultados mostram que são necessários estudos sobre a época de coleta da serapilheira e a influência do clima na germinação das sementes e emergência de plântulas.In fragmented landscapes, large distances from seed sources and strong soil degradation raises difficulties for colonization of new species in reforested areas and in early secondary forests. In this context, the artificial enrichment of reforestation areas with advanced successional level species is vital for the ecosystem sustainability. Methods like transference of soil and litter from mature forests and direct seeding may be alternatives. In this work, samples of surface soil and

    Full Text Available In order to describe community structure and richness in oak and walnut forests occurring along the San Rodrigo, San Diego, Escondido and Arroyo de las Vacas rivers on the Northeastern Coastal Plain (NE Coahuila, Mexico, we established 30 1 000-m² circular plots, where we measured diameter at breast height (DBH and tree heights. Tree regeneration and herb and shrub stratum were assessed in 5 2-m² quadrats per site. A total of 48 species distributed in 29 families were recorded. Families with the largest richness were Poaceae, Asteraceae, and Malvaceae. For the oak forest, tree stratum density and basal area values were 386 stems/ha and 24.36 m²/ha, respectively, whereas for the walnut forest the corresponding values were 302 stems/ha and 21.26 m²/ha. The species with the highest relative importance values were Quercus fusiformis (59.48% and Carya illinoinensis (57.58%. Total tree richness was 14 species, the most common ones being Celtis reticulata and Diospyros texana, followed closely by C. illinoinensis and Q. fusiformis. Anthropogenic impact appears to result in a poor regeneration reflected as a low sapling density, as well as in the reduction and fragmentation of these communities; in turn, this process has led to intrusions of species typical of the xerophytic Tamaulipan Thorn Scrub. Further studies are needed on the regeneration of the dominant species of these forests in order to describe their dynamics and to promote their preservation.Con la finalidad de conocer la estructura y la composición florística de los bosques de encino y nogal situados a lo largo de los ríos San Rodrigo, San Diego, Escondido y Arroyo de las Vacas en la planicie costera nororiental (NE de Coahuila, México, se establecieron 30 parcelas circulares de 1 000 m² en las que se midió el DAP y la altura de las especies arbóreas; además, se evaluó la regeneración de las especies arbóreas y el estrato herbáceo y arbustivo en 5 cuadros de 2 m² por sitio

    Objective: To characterize thermal property of natural gums obtained from the seeds of Diospyros melonoxylon(D. melonoxylon) Roxb, Buchanania lanzan (B. lanzan) spreng and Manilkara zapota (M. zapota) (Linn.) P. Royen syn. Methods: Natural gums were thermally characterized using differential scanning calorimetry (DSC), differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA) under nitrogen atmosphere. Major thermal transitions as well as activation energies of the major decomposition stages were determined. Elemental analysis was performed in order to determine the composition of carbon, hydrogen, nitrogen and sulfur. Results: DSC traces indicated a major intense exothermic transition (around 200℃) followed by weaker exotherm(s). Thermogravimetric analysis showed two phase of weight loss. The first phase has minor weight loss in samples is attributed to the loss of adsorbed and structural water of biopolymers or due to desorption of moisture as hydrogen bound water to the saccharide structure. The second weight loss event may be attributed to the polysaccharide decomposition. The initial decomposition temperature (IDT) was calculated from thermograms obtained of TGA, seed Polysaccharide of D. melonoxylon (IDT 221.21℃), B. lanzan (IPDT 170.4℃) and M. zapota (IPDT 178.6℃) were obtained. According to the integral procedural decomposition temperature (IPDT) values calculated based on the TGA thermograms; D. melonoxylon (IPDT 563.3℃), B. lanzan (IPDT 598.1℃) and M. zapota (IPDT 600.6℃) were obtained respectively. The elemental analysis study shows that the isolated natural Polysaccharides consist of certain percentage of carbon, nitrogen, sulphur and hydrogen in all the gums. Conclusions: The results of the present investigation reveal that the natural gums are thermally stable and these gums can be used as release modifiers in various dosage forms.

    Full Text Available The study of biomass, structure and composition of tropical forests implies also the investigation of forest productivity, protection of biodiversity and removal of CO2 from the atmosphere via C-stocks. The hereby study aimed at understanding the forest structure, composition and above ground biomass (AGB of tropical dry deciduous forests of Eastern Ghats, India, where as a total of 128 sample plots (20 x 20 meters were laid. The study showed the presence of 71 tree species belonging to 57 genera and 30 families. Dominant tree species was Shorea robusta with an importance value index (IVI of 40.72, while Combretaceae had the highest family importance value (FIV of 39.01. Mean stand density was 479 trees ha-1 and a basal area of 15.20 m2 ha-1. Shannon’s diversity index was 2.01 ± 0.22 and Simpson’s index was 0.85 ± 0.03. About 54% individuals were in the size between 10 and 20 cm DBH, indicating growing forests. Mean above ground biomass value was 98.87 ± 68.8 Mg ha-1. Some of the dominant species that contributed to above ground biomass were Shorea robusta (17.2%, Madhuca indica (7.9%, Mangifera indica (6.9%, Terminalia alata (6.9% and Diospyros melanoxylon (4.4%, warranting extra efforts for their conservation. The results suggested that C-stocks of tropical dry forests can be enhanced by in-situ conserving the high C-density species and also by selecting these species for afforestation and stand improvement programs. Correlations were computed to understand the relationship between above ground biomass, diversity indices, density and basal area, which may be helpful for implementation of REDD+ (reduce emissions from deforestation and forest degradation, and foster conservation, sustainable management of forests and enhancement of forest carbon stocks scheme.

As the subject Ethno pediatric medicinal plants are very poorly known, therefore the present ethnopediatric information may prove helpful for further scientific studies. In recent years no valuable study has been made out on ethnopediatric medicinal plants. The number of informats such as local traditional medicinal practitioners and knowledgeable elders has provided the information in frequent field visits to this place. Total number of 20 plant species belonging to 15 families has been enumerated with scientific names families; uses and locality of use. The tribals are, by nature, reluctant to go to the hospital and have a great faith and insist on their own traditional system of medicine. Still the tribals use these plants frequently to cure diseases. The knowledge of this traditional medicine is intact in this region and they use this knowledge mostly for their daily requirements, due to lack of modern facilities. The tribals are very conservative in nature and they do not easily mixed up with other communities for exchange or to share their empirical knowledge.

    Full Text Available Solid wastes from agro-industrial operations can be recycled as non-conventional adsorbents if they are inert and harmless and reduce the cost of wastewater treatment. Tendu leaf Diospyros melanoxylon is the second largest forest product in India after timber and is exclusively used in making local cigarette called Bidi. Waste leaf cutting remaining after making cigarette was used in present study as a biosorbent for the removal of Congo red dye from aqueous solution. It was treated with hydrogen peroxide to obtain biosorbent with increased adsorption capacity. Batch type experiments were conducted to study the influence of different parameters such as pH, initial dye concentration and dosage of adsorbent on biosorption evaluated. The adsorption occured very fast initially and attains equilibrium within 60 min at pH= 6.2 and the equilibrium attained faster after hydrogen peroxide modification. Kinetic studies showed that the biosorption of Congo red on tendu waste followed pseudo-second-order rate equation. The data fitted well to Langmuir and Freundlich isotherm models. Comparison was done on the extent of biosorption between untreated and treated forms of the tendu waste. The maximum adsorption capacity for untreated tendu waste was found to be 46.95 mg/g, which was enhanced by 2.8 times after hydrogen peroxide treatment and was found to be 134.4 mg/g. The adsorption process was in conformity with Freundlich and Langmuir isotherms for Congo red adsorption from aqueous solution. The study demonstrated use of milder chemical treatment of tendu waste to obtain a biosorbent with enhanced dye removal capacity.

    Full Text Available Abstract Background Six herbs in the Plant Genetics Conservation Project that have been used as complementary medicines were chosen on the basis of their medicinal value, namely Terminalia mucronata, Diospyros winitii, Bridelia insulana, Artabotrys harmandii, Terminallia triptera, and Croton oblongifolius. This study aims to evaluate the potential anticancer activity of 50% ethanol-water extracts of these six herbs. Methods Fifty percent ethanol-water crude extracts of the six herbs were prepared. The cytotoxicity of the herbal extracts relative to that of melphalan was evaluated using a hepatoma cell line (HepG2, and examined by neutral red assays and apoptosis induction by gel electrophoresis and flow cytometry after 24 h. Results A significant difference was found between the cytotoxicity of the 50% ethanol-water crude extracts and melphalan (P = 0.000. The 50% ethanol-water crude extracts of all six herbs exhibited cytotoxicity against HepG2 cells, with IC50 values ranging from 100 to 500 μg/mL. The extract of T. triptera showed the highest cytotoxicity with an IC50 of 148.7 ± 12.3 μg/mL, while melphalan had an IC50 of 39.79 ± 7.62 μg/mL. The 50% ethanol-water crude extracts of D. winitii and T. triptera, but not A. harmandii, produced a DNA ladder. The 50% ethanol-water crude extracts of D. winitii, T. triptera, and A. harmandii induced apoptosis detected by flow cytometry. Conclusion The 50% ethanol-water crude extracts of D. winitii, T. triptera, and A. harmandii showed anticancer activity in vitro.

  1. Can Scientific Evidence Support Using Bangladeshi Traditional Medicinal Plants in the Treatment of Diarrhoea? A Review on Seven Plants

    2013-05-01

    Full Text Available Diarrhoea is a common disease which causes pain and may be deadly, especially in developing countries. In Bangladesh, diarrhoeal diseases affect thousands of people every year, and children are especially vulnerable. Bacterial toxins or viral infections are the most common cause of the disease. The diarrhoea outbreaks are often associated with flood affected areas with contaminated drinking water and an increased risk of spreading the water-borne disease. Not surprisingly, plants found in the near surroundings have been taken into use by the local community as medicine to treat diarrhoeal symptoms. These plants are cheaper and more easily available than conventional medicine. Our question is: What is the level of documentation supporting the use of these plants against diarrhoea and is their consumption safe? Do any of these plants have potential for further exploration? In this review, we have choosen seven plant species that are used in the treatment of diarrhoea; Diospyros peregrina, Heritiera littoralis, Ixora coccinea, Pongamia pinnata, Rhizophora mucronata, Xylocarpus granatum, and Xylocarpus moluccensis. Appearance and geographical distribution, traditional uses, chemical composition, and biological studies related to antidiarrhoeal activity will be presented. This review reveals that there is limited scientific evidence supporting the traditional use of these plants. Most promising are the barks from D. peregrina, X. granatum and X. moluccensis which contain tannins and have shown promising results in antidiarrhoeal mice models. The leaves of P. pinnata also show potential. We suggest these plants should be exploited further as possible traditional herbal remedies against diarrhoea including studies on efficacy, optimal dosage and safety.

    We studied moist deciduous forests of Chhattisgarh, India (1) to assess the effect of four levels of historic wildland fire frequency (high, medium, low, and no-fire) on regeneration of seedlings in fire affected areas during pre and post-fire seasons, (2) to evaluate vegetation struc-ture and diversity by layer in the four fire frequency zones, (3) to evalu-ate the impact of fire frequency on the structure of economically impor-tant tree species of the region, and (4) to quantify fuel loads by fire fre-quency level. We classified fire-affected areas into high, medium, low, and no-fire frequency classes based on government records. Tree species were unevenly distributed across fire frequency categories. Shrub density was maximum in zones of high fire frequency and minimum in low-frequency and no-fire zones. Lower tree density after fires indicated that regeneration of seedlings was reduced by fire. The population structure in the high-frequency zone was comprised of seedlings of size class (A) and saplings of size class (B), represented by Diospyros melanoxylon, Dalbergia sissoo, Shorea robusta and Tectona grandis. Younger and older trees were more abundant for Tectona grandis and Dalbargia sis-soo after fire, whereas intermediate-aged trees were more abundant pre-fire, indicating that the latter age-class was thinned by the catastrophic effect of fire. The major contributing components of fuel load included duff litter and small woody branches and twigs on the forest floor. Total fuel load on the forest floor ranged from 2.2 to 3.38 Mg/ha. The net change in fuel load was positive in high- and medium-frequency fire zones and negative under low- and no-fire zones. Repeated fires, how-ever, slowly reduced stand stability. An ecological approach is needed for fire management to restore the no-fire spatial and temporal structure of moist deciduous forests, their species composition and fuel loads. The management approach should incorporate participatory forest manage

  9. Ecology, Impact and Potential Control of Solanum mauritianum in Kenya

    International Nuclear Information System (INIS)

    Solanum mauritianum is considered as an invasive plant with unknown economic value, fast growing and aggressive gap colonizer associated with forest disturbance. It belongs to the family of Solanaceae and can grow to over 20 m in height. It is native to Southern America and threatens integrity of several natural forest in Western kenya. Surveys were undertaken in 1998 and 2005/2006 at mount Elgon and Kakamega forests to evaluate the species ecology, spread and impact on other tree species. Total enumeration of seedlings, saplings and mature individuals was done over two 1-ha-blocks in each forest. The total number of 0.1 ha plots sampled was 20 per forest in relatively lightly and heavily disturbed areas. The results the species the species relative dominance in Mount Elgon increased from 1.0% in 1998 to 48.9% in 2006, out competing the regeneration of other trees. For example at Labaa, the once dominant Diospyros abyssinica with 36% relative dominance in 1998 declined to 1.9% in 2006. This threat to the health of ecosystems is not yet noticeable in Kakamega forest where the weed relative stocking was 0.2%. A strong positive correlation (n=5, rs=0.9, p=0.95) between S. mauritianum established and charcoal burning still exists in Mount Elgon. Thorough literature review and field observations confirmed about the characteristics of s. mauritanium as weed. Proliferation strategies and opportunities underlying the successive invasion by weed have been reviewed and elements of an integrated, multidisciplinary effort to control the adverse impact of the weed in forest and outside forests identified. Measures to check the invasiveness of these species include include reducing forest gaps, monitoring it's reproductive biology to eliminate mother trees before seeding, educative campaigns to prevent local communities from domesticating this species on their farms, research programme on S. mauritianum to understand causes of it's competitive advantage over others and search

We studied the effects of boron (B and calcium (Ca sprayed on the trees during three consecutive years, on the development of skin cracks, grooves and browning in persimmon fruit under CS in Farroupilha, RS, Brazil (29°31' south, 51°21' west, about 750 m altitude. A homogeneous orchard area of 0.5 ha was delimitated and three sets of five plants for each treatment were randomly selected. The persimmon trees were sprayed at a 20 day interval, from 15th January until harvest, for three consecutive years, with: T1 water; T2 calcium nitrate at 0.5% (m/v; T3 calcium chloride at 0.5% (m/v; and T4 boron at 0.3% (m/v. The fruit were harvest with orange-reddish colour; 18-20°Brix, pulp firmness of 45 to 60N, and kept under CS at 0±1°C for 45 days. The fruits were evaluated immediately before CS, after six hours at 23±2°C after removal from CS, and after four days at 23±2°C after removal from CS. Equally boron and calcium sprayed on the trees prevented skin cracks, skin grooves and skin browning. Besides, when boron was sprayed on the trees, the mentioned effects were additive in the following year.As principais alterações indesejáveis observadas no período pós-colheita de caquis em armazenamento refrigerado (AR são a perda de firmeza de polpa, e a ocorrência de escurecimento epidérmico e de podridões.

    The grapefruit seed extract (GSE), a natural plant extracts from the edible plants used as an extremely potent broadspectrum bactericide, and fungicide should be very effective for the fruit preservation. In this study, Grape (Vitis vinifera L.) and persimmon (Diospyris kaki L.) easily undergone deterioration, were selected as model fruits. Eight fungi familiar to the rotting cause of grape and persimmon were used to testify the antifungal activity of GSE. The results of antifungal assay by the agar diffusion method indicated that GSE can efficiently inhibit the growth of tested fungi. The values of minimal inhibitory concentration (MIC) also range from 39.06×10-6 to 625×10-6 as demonstrated by the similar results with the data taken from agar diffusion assay. In the storage application assay of both grape and persimmon, the obvious differences in sensory quality and microorganism indexes between the GSE treated fruits and control fruits support that GSE has both the strong antifungal activity and antioxidative activity. Polyphenolic compounds, rich in GSE used as the main effective antioxidative component,are capable to prevent fungal infection in storage to a large extent and to postpone ripening and aging of fruits effectively by scavenging the free radical and impacting a series of enzyme relating to postharvest physiological metabolism of fruits, particularly in the key parts liking stem and calyx. The obtained results also indicated that GSE can decrease browning and rot ratio,prolong the preservation period, ensure the quality of grape and persimmon and can be used as an effective and safe preservative.%葡萄柚种子提取物是潜在的广谱性细菌、真菌杀菌剂,应该在果蔬保鲜中具有很好的效果.本研究选取比较容易受真菌感染的葡萄和柿子作为模式保鲜材料并且测试了葡萄柚种子提取物对8种与这两种水果腐败相关的真菌的抑制效果.结果表明,这8种真菌的最小抑制浓度分别在39

    因为“冰臼”一词尚未得到地学界认可,建议继续用“冰川壶穴”来替代“冰臼”。由于生成冰臼(冰川壶穴)与壶穴的水动力条件和地貌形态相似,所以单从形态难以区分广东河床上的壶穴或冰臼,只有确定广东是否发育过第四纪冰川之后,才可能确定广东是否有冰臼。本文从气候、地貌和生物角度证实广东未出现过第四纪冰川环境,并认为所谓:①水应力集中一点生成冰臼;②花岗岩坚硬不能生成壶穴;③二、三百万年前生成冰臼等冰臼论观点是不成立的。%After tens dictionaries of Chinese and Chinese-foreign language are looked up, there is not nearly the“bingjiu” ①term in it, it is reflected that the term is still not approved by most geonomist, to substitute“bingchuan huxue”① for “bingjiu” continually is proposed. Owing to waterpower condition and geomorphologicshape growing moulin and pothole are similar, so from form only distinguishing the pothole or moulin on theriverbed are difficult, only if fixing there is glacier in Guangdong, the moulin can just be fixed in Guangdong. Itis confirmed that environment of Quaternary glacier in Guangdong appeared not from following angles of cli-mate, landform and organisms etc.: Inferred annual mean temperature was higher than 63 in glacial epoch atthe highest peak-Shikengkong its elevation was 1902m in Guangdong, the coldest annual mean temperature was13℃ + in the glacial epoch inferred by sporopollen data in Jiexi and Fengshun; there is not the glacial landformin the middle-low mountains of Guangdong and there is not the document report on established palaeo-glaeier re-mains; the plant fossil in Early Pleistocene Zhanjiang Fm. is Bauhinia-Diospyros-Myrica-phyllites-Rhus combi-nation, today there are still a large number relict flora. The following moulin theory on mechanism for the for-mation and conservation of moulin is untenable: (1) moulin grows

    The two-stage expert consulting research is carried out to set up the diagnostic criteria for the abnormal hilit matured and removed from the body on the abnormal savda type asthma in traditional Uighur medicine based on the Delphi method. In the first stage, an enquiry form is formulated to include key syndrome characteristics identified from the past research results of our research group, and is sent to 30 experts in this field from all around the Xinjiang province. One round Delphi technique is conducted in this stage. Then, 11 kinds of syndrome characteristics, such as the gradual improvement of the mental color, the clear urine in large amount, thick and (or) wavy pulse, are selected as the diagnostic criteria for the abnormal hilit matured on the abnormal savda type asthma and 10 kinds ofsyndrome characteristics, such as the significant improvement of the sleep quality, the tongue moisture and restore the state of originaltemperament, a little black and rusl-colored stool first, then pale yellow or kaki, are selected as the diagnostic criteria for the abnormal hilit removed from the body on the abnormal savda type asthma in accordance with a high expert consensus of frequency greater than 70% (21 out of 30 experts). In the second stage, a new enquiry form is formulated based on the screened results of the first stage, and the weight coefficients of the selected syndrome characteristics are studied, and the two-round Delphi technique is used in this stage. 30 copies of valid questionnaires were responded each round. The expert authority coefficient is 0.87 on average, which would be considered as a high authority degree. By analyzing the weight coefficients of each selected syndrome characteristics, 6 kinds of syndrome characteristics are considered as the chief symptoms and other 5 kino's of syndrome characteristics are considered as the subsequent symptoms for diagnosing the abnormal savda type asthma abnormal hilit (matured or not). 5 kinds of the chief

    here, and working wonderfully. Tortoises pull the weeds, apply the fertilizer, and germinate the seeds. Regarding the latter, recently published experiments2 show that passing through the slow digestive system of a giant tortoise is just what some of these hard - to - germinate seeds of rare native plants have been waiting for. The authors show conclusively that the highly endangered, large - seeded native ebony tree (Diospyros egrettarum is germinating and thriving on the remarkable 25-hectare Ile aux Aigrettes Reserve, a small island off Mahebourg, Mauritius, thanks to the Aldabra tortoises reintroduced there by the Mauritian Wildlife Foundation. At the Leguat Reserve on Rodrigues, guides lead thousands of visitors per year through huge spectacular limestone caves that have yielded the fossils of giant tortoises, Solitaires, and the other extinct biota of Rodrigues. Their tour, and the excellent museum on the Reserve, make that wonderful connection between the fossils of a remarkable extinct fauna, and the rare plants and surviving fauna of large handsome fruit bats, rare land snails, nesting White - tailed Tropicbirds, and the surviving cousins of the native giant tortoises now roaming the canyons and plateaus of the Reserve. What am I doing here? To begin with, my wife Lida Pigott Burney and I have in recent years started our own similar rewilding project on the island of Kaua`i, in the Hawaiian Islands. We likewise have a cave system, full of fossils of the extinct animals, as a centerpiece for restorations on worn - out farmland that feature thousands of native plants, some quite rare. Our big fossil herbivores, giant flightless ducks and geese, are all extinct, and alas, tortoises never reached Hawaii. So we laboriously pull the weeds, tons of them, with the help of the school children of Kaua`i and hundreds of volunteers. The current question I and my colleagues are asking is, could giant tortoises give us a hand, serving as ecological surrogates for the lost
