  • A special type of indigenous knowledge on plants utilization and farming system was explored by the Garo tribe community in the North-East region of Bangladesh, which correspond to the severe dependence on homestead forest. Results show that the Garo are totally dependent on the natural resources and that the extent of their dependency is faithfully reflected in their ethno-botanical knowledge. Dependencies that the study addressed focused on various aspects of food, fruit, energy, timber and health care on plants products. Garo tribe community in Bangladesh followed agrosilvipastoral system in their homesteads. They have indigenous hunting procedure to trap the animal in the forest. A total of 9 foods, 15 fruits, 12 energy-producing and 11 timber species was found and recorded that the Garo used in their daily life. Moreover, Garo used 23 medicinal plants species and have vast indigenous knowledge about using herbal medicine in daily health care practices. The Garo women do mostly the household activities, managing homestead forest and helping agricultural field where men perform all hard working activities like ploughing, cutting trees, digging the soil, preparation of horticultural and agricultural land, hunting, etc. The overall quality of life of the Garo could be considerably upgraded if ethno-botanical issues and their own indigenous knowledge will complement with scientific knowledge. The findings of the study conclude that the conservation of the indigenous knowledge of the Garo tribe related to plants utilization can also be turned to good account in forest conservation and is an important tool in this tribal area of Bangladesh.

  • Background: The objective of this study was to make colloidal dispersions of the active compounds of radix of Angelica gigas Nakai that could be charaterized as nano-composites using hot melt extrusion (HME). Food grade hydrophilic polymer matrices were used to disperse these compound in aqueous media. Methods and Results: Extrudate solid formulations (ESFs) mediated by various HPMCs (hydroxypropyl methylcelluloses) and Na-Alg polymers made from ultrafine powder of the radix of Angelica gigas Nakai were developed through a physical crosslink method (HME) using an ionization agent (treatment with acetic acid) and different food grade polymers [HPMCs, such as HP55, CN40H, AN6 and sodium alignate (Na-Alg)]. X-ray powder diffraction (XRD) analysis confirmed the amorphization of crystal compounds in the HP55-mediated extrudate solid formulation (HP55-ESF). Differential scanning calorimetry (DSC) analysis indicated a lower enthalpy (${\Delta}H=10.62J/g$) of glass transition temperature (Tg) in the HP55-ESF than in the other formulations. Infrared fourier transform spectroscopy (FT-IR) revealed that new functional groups were produced in the HP55-ESF. The content of phenolic compounds, flavonoid (including decursin and decursinol angelate) content, and antioxidant activity increased by 5, 10, and 2 times in the HP55-ESF, respectively. The production of water soluble (61.5%) nano-sized (323 nm) particles was achieved in the HP55-ESF. Conclusions: Nano-composites were developed herein utilizing melt-extruded solid dispersion technology, including food grade polymer enhanced nano dispersion (< 500 nm) of active compounds from the radix of Angelica gigas Nakai with enhanced solubility and bioavailability. These nano-composites of the radix of Angelica gigas Nakai can be developed and marketed as products with high therapeutic performance.

  • Background: The study of phenolic compounds profiles and antioxidative activity in ginseng fruit, leaves, and roots with respect to cultivation years, and has been little reported to date. Hence, this study examined the phenolic compounds profiles and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free-radical-scavenging activities in the fruit, leaves, and roots of Korean ginseng (Panax ginseng Meyer) as a function of cultivation year. Methods: Profiling of 23 phenolic compounds in ginseng fruit, leaves, and roots was investigated using ultra-high performance liquid chromatography with the external calibration method. Antioxidative activity of ginseng fruit, leaves, and roots were evaluated using the method of DPPH free-radical-scavenging activity. Results: The total phenol content in ginseng fruit and leaves was higher than in ginseng roots (p < 0.05), and the phenol content in the ginseng samples was significantly correlated to the DPPH free-radical-scavenging activity ($r=0.928^{****}$). In particular, p-coumaric acid ($r=0.847^{****}$) and ferulic acid ($r=0.742^{****}$) greatly affected the DPPH activity. Among the 23 phenolic compounds studied, phenolic acids were more abundant in ginseng fruit, leaves, and roots than the flavonoids and other compounds (p < 0.05). In particular, chlorogenic acid, gentisic acid, p- and m-coumaric acid, and rutin were the major phenolic compounds in 3e6-yr-old ginseng fruit, leaves, and roots. Conclusion: This study provides basic information about the antioxidative activity and phenolic compounds profiles in fruit, leaves, and roots of Korean ginseng with cultivation years. This information is potentially useful to ginseng growers and industries involved in the production of high-quality and nutritional ginseng products.

  • Objectives : The experiment was performed to investigate promotive effects of haeae-tang (HET) extract, a traditional Korean medicinal recipe, on hair growth, protein and gene expression in hair-removed C57BL/6. Methods : In experiment, animals were divided into 3 groups including normal (vehicle), HET ethanol extract and 5% minoxidil-treated groups (Minoxidil, positive control). The vehicle or testing samples were daily treated with 0.2ml per on hair-shaved dorsal skin of C57BL/6mice for 15 days. Effects of testing samples on hair growth was monitored through phototrichogram analysis by folliscope on the initial, $5^{th}$, $10^{th}$, $15^{th}$ day, respectively. Also, gene and protein expressions of vascular endothelial growth factor (VEGF) and Insulin like growth factor-1 (IGF-1), relevant to hair growth, were examined. Results : Hair density and hair thickness of Minoxidil treated-group was significantly increased compared to that of vehicle application on the $15^{th}$day, respectively. Dorsal hair density of HET treated-group was significantly increased compared to that of vehicle application on the $15^{th}$day. In addition, the Minoxidil group significantly increased the expression of cutaneous IGF-1 protein and mRNA compared to that of the vehicle-applied group on the $15^{th}$ day. And HET-treated group significantly increased the expression of dorsal VEGF protein compared to that of the vehicle-applied group on the $15^{th}$ day. Conclusions : These results suggest that this Korean medicinal recipe, HET has promoting activity on hair growth in an Alopecia animal model thus it can be used as a material of agent or products for improvement or prevention of alopecia.

  • In attempting to identify effective anticancer drugs from natural products that are harmless to humans, we found that the gomisin J from Schisandra chinensis fruit has anticancer activity. Schisandra chinensis fruits are used in traditional herbal medicine and gomisin J is one of their chemical constituents. In the present study, we examined the anticancer activity of gomisin J in MCF7 and MDA-MB-231 breast cancer cell lines and in MCF10A normal cell line, in a time- and concentration-dependent manner. Our data revealed that gomisin J exerted a much stronger cytotoxic effect on MCF7 and MDA-MB-231 cancer cells than on MCF10A normal cells. Gomisin J suppressed the proliferation and decreased the viability of MCF7 and MDA-MB-231 cells at relatively low (<10 ㎍/ml) and high (>30 ㎍/ml) concentrations, respectively. Our data also revealed that gomisin J induced necroptosis, a programmed form of necrosis, as well as apoptosis. Notably, gomisin J predominantly induced necroptosis in MCF7 cells that are known to have high resistance to many pro-apoptotic anticancer drugs, while MDA-MB-231 exhibited a much lower level of necroptosis but instead a higher level of apoptosis. This data indicated the possibility that it may be used as a more effective anticancer drug, especially in apoptosis-resistant malignant cancer cells. In an extended study, gomisin J exhibited a strong cytotoxic effect on all tested various types of 13 cancer cell lines, indicating its potential to be used against a wide range of different types of cancer cells.

  • According to the Chinese and Korean medicinal and herbal literature, SSG(Silsosangami) is effective for the treatment of inflammation, hyperlipemia and arteriosclerosis. The pharmacological action of SSG has been limitedly studied in regard to ischemic infarction. This herbal medicine has been shown to express diverse activities such as immunomodulating, anti-infarction, anti-allergic and anti-inflammatory effects. Antisclerotic effects of SSG in experimentally induced atherosclerosis in rabbits have also been reported. However, pharmacological mechanisms of SSG on lipid metabolism and atherosclerosis formation are poorly understood. The present paper reports the effect of extracts obtained from SSG on endotoxin-induced experimental DIC in rats. Also, these were tested for their effect on endotoxin-induced blood platelet aggregation, thrombin-induced conversion of fibrinogen and fibrinolysis in vitro experiments with aspirin as a positive agent. The anti-thrombic properties of SSG were also investigated by means of analytical parameters of bood composition. The extracts of SSG and its seven herbs, except Cnidii Rhizoma and Carthami Flos, inhibited the endotoxin-induced DIC and thrombosis in rats. Also the extract inhibited the endotoxin-induced decrease in blood platelets and fibrinogen, and endotoxin-induced increase in fibrin degradation products (FDP) on disseminated intravascular coagulation in normal rats.

  • This study has been geared to document primary information on common complementary and alternative medicines (CAM) used to treat and/or manage common dermatological disorders in Mauritius, a tropical multicultural island in the Indian Ocean. Data from 355 key informants was collected via a semi-structured questionnaire. Pearson correlation and Chi-squared test were performed to delineate any association. Quantitative indexes including the Importance Value (IV) and fidelity value were calculated. Results tend to indicate that cultural reasons were behind the use of CAM among Mauritians and traditional knowledge was mainly acquired either from parents/relatives or from self-experience. Among the medicinal plants mentioned, Aziadiracta indica (IV = 0.78) and Paederia tomentosa (IV = 0.70) were found to be most used plants. Calendula officinalis (IV = 0.15), Centella asiatica (IV = 0.22) and Agauria salicifolia (IV = 0.11) were also recorded to be used for common dermatological disorders though greatly under-utilised. Animal products were mentioned by 38.0% respondents and cow ghee was found to be commonly used in the management of measles (IV = 0.88). Spiritual healing was found to be used mainly for measles and warts. Given the plethora of novel information documented from the present survey, it can be suggested that the Mauritian population still relies to a great extent on CAM which needs to be preserved and used sustainably. Nonetheless, further investigation is required to probe the possible active constituents that could be the basis of an evidence based investigation to discover new drugs.

  • Berberis is an important medicinal plant, of the family Berberidaceae. Different Berberis species and their parts are very common in herbal drug markets of India and world over as an adulterant/substitute to 'Daruharidra' i.e. B. aristata DC. Antimicrobial activity of 50% hydroalcoholic extracts of stem of four Berberis species viz. B. aristata DC., B. asiatica Roxb. ex DC., B. chitria Lindl. and B. lycium Royle and the isolated alkaloid berberine were tested against eleven bacterial and eight fungal strains. The extracts with the strongest antibacterial activity was obtained from B. lycium followed by B. aristata, B. asiatica and B. chitria. Based on these results it is possible to conclude that the hydroalcoholic extract and alkaloid (berberine) has stronger and broader spectrum against bacterial strains as compared to fungal strains. The result obtained in the present study authenticates and support the use of these plants in folklore medicine for treatment of various infectious diseases caused by the bacterial pathogens. However, an attempt has been made to explore the possibilities of utilizing stem part rather than roots of these species with the aim to conserve this species which is over exploited due to diverse use of its root. These findings will stimulate the search for novel, natural products as new antibacterial/antifungal agents which may be useful to pharmaceutical industries.

  • Matricaria Chammomillal L., Foemiculum Vulgare mill, and Plantago Psylium L. have been screened for their hepato protective activities against liver damge induced by $CCl_4$ intoxication in mice. Hydroalcoholic extractions (2:8) of herbal drugs were concentrated in vacuo and concentrated crude extracts of Matrica Chammomilla L. and Foeniculum Vulgare mill were orally administered at doses of 100 mg/kg, 200 mg/kg, 400 mg/kg, and 800 mg/kg. Plantago Psyllium was given at doses of 50 mg/kg, 100 mg/kg, 200 mg/kg, and 400 mg/kg. Liver protective activities of these herbs were determined after administration of $CCl_4$ Liver size, serum enzyme activities, sleeping time, and histopatology of the liver were examined one hour after administration of $CCl_4$. ALT and AST activities, liver weight and sleeping time decreased in groups that received 400 mg/kg of Matricaria Chammomilla L. or Foeniculum Vulgare. Histological investigation showed significant increase in hepatic cell regeneration and reduction in liver injury. The group that received 100 mg/kg Plantago Psylium showed liver protection but protection was not significant in other doses.
