Abstract
Besides (-)-epicatechin,epicatechin-(4β-8)-epicatechin (procyanidin B2),epicatechin-(4β-6 )-epicate-chin (procyanidin B5),epicatechin-(4β-8,2β-O-7)-epicatechin (proanthocyanidin A2)and epicatechin-(4β-8)-epicatechin-(4β-8)-epicatechin (procyanidin C1),which were isolated before from Adansonia digita-ta,in this work an A-type proanthocyanidin trimer,i.e.epicatechin-(4β-8)-epicatechin-(4β-8,2β-O-7)-epicatechin,tetrameric procyanidin D1,i.e.epicatechin-(4β-8)-epicatechin-(4β-8)-epicatechin-(4β-8)-epicatechin and a polymeric compound were isolated from the pericarp (fruit wall)of the fruits for the first time from this plant .The antioxidant activity of different fractions and pure compounds was experimentally e-valuated in the DPPH - assay.The ethyl acetate fraction,and most of the isolated compounds displayed a high activity (IC50 2.40-9.60 μg/ml)compared with the reference antioxidant Trolox (IC50 12.18 μg/ml)as a standard.
