Abstract:

Article Preview

The alcoholic extract of the Apocynum venentum (AV) bark were purified by silica gel column chromatography. The isolated chemical constituents were identified by MS, NMR, IR spectra. The main chemicals isolated from AV bark were quercetin (1), kaempferol (2), isoquercitrin (3), luteolin (4), hyperoside(5), 7-hydroxy-6-methoxy-2H-1-benzopyran-2-one (6), b-sitosterol (7), stigmasterol (8), 3, 4-dihydroxy-benzoic acid methyl ester (9), 3, 5-dihydroxybenzaldehyde (10) and 3, 4-dihydroxy-benzoic acid (11). The compounds (1)~(6) and (8)~(11) were obtained from AV bark for the first time.
