- Phytochemical investigation of the aerial parts of Berchemiella wilsonii (Schneid.) Nakai (Rhamnaceae) led to the isolation of four flavonoids (1–4), three phenolic acids (5–7), two megastigmane derivatives (8–9) and one triterpene (10). The structures of these compounds were elucidated as taxifolin (1), (−)-epicatechin (2), quercetin 3-O-a-l-arabinopyranoside (3), vitexin (4), methyl p-hydroxycinnamat (5), 3,4-dihydroxybenzoic acid (6), 2-hydroxy-4-methoxy-3,6-dimethyl benzoic acid (7), (3S,5R,6R,7E,9S)-3,5,6,9-tetrahydroxy-7-en-megastigmane (8), (6S,9R)-roseoside (9) and lupeol (10) on the basis of NMR spectral data and comparison with literature values. These results are the first chemical constituent data of the genus Berchemiella, and the chemotaxonomic significance of these compounds is discussed.
