Abstract
The A-type proanthocyanidin, epigallocatechin-(2beta-->7,4beta-->8)-epicatechin, together with the known epicatechin, luteolin 3'beta-D-glucopyranoside, chrysoeriol 7beta-D-glucopyranoside and 2-methylpentan-2,4-diol, were isolated from leaves of Dioclea lasiophilla. The structures were established on the basis of their spectral data. Antioxidant activities of isolates were measured using the autooxidation of beta-carotene in a linolenic acid suspension method.Entities:
