Pharmacognostical and Preliminary Phytochemical Screening of Vitisvinifera Leaves
Author: Ashok Kumara, Amit Kumar, Pragib and Varun Kumar
Abstract:
Vitisvinifera L. (vitaceae) is a good sources of phytochemicals and are suitable raw materials for the production of antioxidant/antiageingdietary supplements. The present work emphasise to assess thepharmacognostical evaluation as: organoleptic features, proximate composition, phytochemical screening of leaves of flame red grape leaf. The results showed that grape leaf content was fibers 25.20%, total lipids 8.40%, proteins 10.0%, ash value 1.58%, carbohydrates 25.37%, LOD 1.40% and moisture10.75%, resperctively. Phytochemical analysis of flame red grape leaf ethanolic extract (EE) and chloroform extract (CE) showing the presence resveratrol (stillbens) of anthocyanins, coumarin, steroids, terpenoids, anthocyanins, emodins, glycosides (Anthraquinones&cardinolides), flavonoids and phenols iis significantly present in EE as compared to CE. Tannins is present in high amount while coumarin is absent in chloroform extract. Results reflect that ethanolic extract have good pharmacognostical profile as compared to chloroform due presence of flavonoids, anthraquinones, saponins, carbohydrates, phenol and terpenoids. .
