Chemical constituents of Discocleidion rufescens

To study chemical constituents of leaves from Discocleidion rufescens.Column chromatography and spectroscapic methods were used to isolate and identify the constituents.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).Compounds 1, 2, 8, 11, 13 and 15 were isolated from the genus Discocleidion for the first time.
