Besides (-)-epicatechin, epicatechin-(4β-8)-epicatechin (procyanidin B2), epicatechin-(4β-6)-epicatechin (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 digitata [1], 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 [2]. The antioxidant activity of different fractions and pure compounds was experimentally evaluated in the DPPH· assay. The ethyl acetate fraction, and most of the isolated compounds displayed a high activity (IC50 2.40-9.60µg/ml) compared with the reference antioxidant [3] Trolox (IC50 12.18µg/ml) as a standard.
