Abstract
OBJECTIVE: To study chemical constituents of leaves from Discocleidion rufescens. METHOD: Column chromatography and spectroscapic methods were used to isolate and identify the constituents. RESULT: Fifteen compounds were isolated and identified as chrysophanol (1), physcione (2), taraxerol (3), beta-sitosterol (4), daucosterol (5), scopoletin (6), apigenin (7), acacetin-7-O-beta-D-glucoside (8), apigenin-7-O-beta-D-glucoside (9 ), luteolin (10), diosmetin-7-O-beta-D-glucoside (11), luteolin-7-O-beta-D-glucoside (12), gallic acid (13), amentoflavone (14) and myo-inositol (15). CONCLUSION: Compounds 1, 2, 8, 11, 13 and 15 were isolated from the genus Discocleidion for the first time.
