| 1 | Morpho-anatomical and physicochemical studies of Fumaria indica(Hausskn.)Pugsley显示文摘Objective:To study morpho-anatomical characters and physicochemical analysis of Fumaria indica(F.indica)(Hausskn.)Pugsley,(Fumariaceae),an important medicinal plant used extensively for treating a variety of ailments in various system of indigenous medicine.Methods:Evaluation of the different parts of the plant was carried out to determine the morphoanatomical,physicochemical,phytochemical and HPTLC fingerprinting profile of F.indica and other WHO recommended methods were performed for standardization.Results:Morphoanatomical studies showed compound and pinnatifid leaf,4 to 6 cm in length,linear and oblong in shape and anomocytic arrangement of stomata,thin walled parenchymatous cells,scattered,sclerenchymatous,capped vascular bundles and radiating medullary rays.Physicochemical studies showed foreign matter 0.2%,loss on drying 6.8%,total ash 16.77%,alcohol and water soluble extractives 8.92%and 20.26%,respectively,sugar 17.75%,starch 22.97%and tannins 2.37%.Phytochemical evaluation revealed the presence of carbohydrate,alkaloids,flavonoids,saponins,tannins and sterol.Thin layer chromatography was carried out with different solvents and the best solvent system was chloroform and methanol in 80:20 ratio and revealed 12 spots with different R_f value under UV light 366λ.Conclusions:The results of the study can serve as a valuable source of information and provide suitable standards for identification of this plant material for future investigations and applications. | Prakash Chandra Gupta Ch V Rao | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，10： | 2 |
| 2 | Biological activities of Wiedemannia multifida(Linnaeus) Bentham and Wiedemannnia orientalis Fisch.& Mey.显示文摘Objective:To evaluate total phenolic,antioxidant and antimicrobial activities of methanolic extracts of the Wiedemannia multifida(W.multifida)and Wiedemannnia orientalis(W.orientalis).Methods:Phosmomolybdenum assay,DPPH radical scavenging activity andβ-carotent-linoleate bleaching were used to evaluate the antioxidant capacity.Results:The total phenolics were found to be(22.45±0.60)and(9.53±0.00)mg gallic acid equivalents(GAE)/g in W.multifida and W.orientalis extracts,respectively.The predominant phenolic compounds identified by HPLC-DAD in the both extracts were rutin+ellagic acid and kaempferol.Total antioxidant capacity and DPPH radical scavenging activity of W.multifida were higher than W.orientalis.Inβ-carotene-linoleic acid system,both extracts exhibited strong inhibition against linoleic acid oxidation.Antimicrobial activity was assessed by the agar diffusion method against fifteen microorganisms.Both extracts exhibited remarkable antibacterial activity.Conclusions:The present study suggests that methanolic extracts of W.multifida and W.orientalis could be a good source of antioxidant and antimicrobial agents in foods,pharmaceuticals preparations. | Sevil Albayrak Ahmet Aksoy | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，3： | 0 |
