| 6 | Anti-inflammatory and antioxidant activities of ethanolic extract of aerial parts of Vernonia patula(Dryand.)Merr.显示文摘Objective:To investigate the inflammatory and antioxidant activities of ethanolie extract of aerial part of Vernonia patula(Dryand.)Merr(EAV).Methods:The anti-inflammatory activity of EAV was studied using carrageenan and histamine-induced rat paw edema test at different doses(100.200 and 400 mg/kg body weight).DPPH free radical scavenging,nitric oxide scavenging,reducing power and Fe^(2+)ion chelating ability were used for determining antioxidant activities.Results:The EAV,at the dose of 400 mg/kg,showed a significant anti-inflammatory activity(P<0.01)both in the carrageenan and histamine-induced oedema test models in rats,showing62.86%and 64.42%reduction in the paw volume comparable to that produced by the standard drug indomethacin(67.26%and 66.01%)at 5 h respectively.In DPPH free radical scavenging test,IC_(50)value for EAV was found fairly significant 36.59μg/mL when compared to the IC_(50)value of the reference standards ascorbic acid 8.97μg/mL.The IC_(50)values of the extract and ascorbic acid were 47.72 and 12.39μg/mL,respectively in nitric oxide scavenging assay.The IC_(50)value of the EAV(33.59μg/mL)as percentage of Fe^(2+)ion chelating ability was also found significant compared to that of EDTA(9.16μg/mL).The maximum absorbance for reducing power assay was found to be1.928 at 100μg/mL when compared to 2.449 for standard ascorbic acid.The total phenolic content was 198.81 mg/g of gallic acid equivalent.Acute toxicity test showed that the plant might be safe for pharmacological uses up to a dose level of 3200 mg/kg of body weight in rats.Conclusions:Therefore,the obtained results suggest the acute anti-inflammatory and antioxidant activities of the EAV and thus provide the scientific basis for the traditional uses of this plant part as a remedy for inflammations. | Arpona Hira Shubhra Kanti Dey Md.Sariful Islam Howlader Arif Ahmed Hemayet Hossain Ismet Ara Jahan | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，10： | 1 |
| 7 | Extraction of a novel tanning agent from indigenous plant bark and its application in leather processing显示文摘The use of vegetable tanning materials in leather processing has drawn attention as an alternative to basic chromium sulphate for its natural abundance and environmental aspects. In this work, an attempt has been made to extract veg-etable tannins from Xylocarpus granatum bark using different solvents (e.g., water, methanol, ethanol, and chloroform) and compare with conventional vegetable tanning agents such as mimosa and quebracho. The highest extraction efficiency was observed 31.22% by methanol. The presence of tannin content and polyphenolic compounds, e.g. (-)epicatechin (503 mg/100 g dry extract), catechin hydrate (218 mg/100 g dry extract), catechol (29 mg/100 g dry extract) were ensured by UV-Vis, FT-IR spectroscopy and HPLC. Again, condensed tannins, moisture content, and pH of the methanol extracted tannin were found 47.80%, 5.82%, and 3.97 respectively. The leather tanned by Xylocar-pus granatum tannin showed a shrinkage temperature of 86.34 ± 1.52 °C. Other properties such as tensile strength, tear strength, grain cracking load, and distention at grain cracking were comparable to conventional vegetable- tanned leather. The cross-sectional morphology of the tanned leathers was also characterized by scanning electron microscopy (SEM) which revealed a compact structure of the leather fibers. In light of the findings from the study, X. granatum bark tannin could be a well alternative to chromium and a new source of vegetable tannin for the leather industry. | Raju Kumar Das Al Mizan Fatema Tuj Zohra Sobur Ahmed Khondoker Shahin Ahmed Hemayet Hossain | 2022 | Journal of Leather Science and Engineering2022，4，1： | 0 |
