Resumen:
The A-type proanthocyanidin, epigallocatechin-(2β→7,4β→8)-epicatechin, together with the known epicatechin, luteolin 3′β-d-glucopyranoside, chrysoeriol 7β-d-glucopyranoside and 2-methylpentan-2,4-diol, were isolated from leaves of Dioclea lasiophylla. The structures were established on the basis of their spectral data. Antioxidant activities of isolates were measured using the auto-oxidation of β-carotene in a linolenic acid suspension method.
