[Flavonoids of 3 cultivars vine leaves, Vitis vinifera L. var. tinctoria (Alicante, Carignan, Grand noir). Value in chemical control].

Abstract

Three flavonoids were isolated and identified from the leaves of 3 cultivars vine Vitis vinifera L. var. tinctoria (Alicante, Carignan and Grand noir): hyperin, isoquercitrin and quercetin 3-O-beta-D glucuronic acid. TLC analytic control and HPLC determination are proposed in this paper.
