Abstract
The 80% methanol of the pericarp of the fruits of Adansonia digitata. L. (Bombaceae) was found to contain proanthocyanidins as major compounds, vi.z., (-)-epicatechin, epicatechin-(4 → β.8)-epicatechin B2, epicatechin-(4 → β.6)-epicatechin B5, epicatechin-(2β. → O → 7, 4β. → 8)-epicatechin A2, and epicatechin-(4 → β.8)-epicatechin-(4 → β.8)-epicatechin C1. All the isolated compounds were isolated by open-column liquid chromatography (CC) using Sephadex-LH 20 as stationary phase. Elution of the column was performed with EtOH. The structures of these compounds were elucidated by means of TLC, ESI-MS, and 1D and 2D NMR spectroscopy.
