[Studies on the chemical constituents of flowers of Prunus mume].

OBJECTIVE: To study the chemical constituents of flowers of Prunus mume. METHODS: Compounds were separated by silica gel. Their structures were identified and elucidated by spectral analysis and chemical methods. RESULTS: Eight compounds were obtained and identified as benzoic acid (I), isorhamnetin (II), quercetin (III), kaempferol-3-O-beta-D-galactopyranoside (IV), isorhamnetin-3-O-beta-D-glucopyranoside (V), isoquercitrin (VI), hypericin (VII) and rutin (VIII). CONCLUSION: Among them, II-VII are isolated from this plant for the first time.
