OBJECTIVE: To investigate the chemical constituents in the flowers of Punica granatum. METHODS: The chemical constituents were separated by silica gel column chromatography and their structures were determined by spectroscopic experiments. RESULTS: As a result, twelve compounds were isolated and identified as oleanolic acid (1), ursolic acid (2), palmitic acid (3), tricin (4), catechin (5), rutin (6), apigenin (7), apigenin-7-O-glucoside (8), 2S, 3S, 4S-trihydroxypentanoic acid (9), gallic acid (10), beta-stitosterol (11), and daucosterol (12). CONCLUSION: Compounds 3, 4, 7, 8 and 9 are separated from this plant for the first time, and compounds 3, 4 and 9 are isolated from this genus for the first time.
