Abstract:
AIM To investigate the chemical constituents from the leaves of Cucurbita moschata (Duch.ex Lam.) Duch.ex Poiret.METHODS The ethyl acetate and n-butanol fractions of 70％ ethanol extract from C.moschata leaves were isolated and purified by silica,Sephadex LH-20,ODS and preparative TLC,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Thirteen compounds were isolated and identified as β-amyrin (1),phytol (2),α-linolenic acid (3),α-methyl linolenate (4),palmitic acid (5),ethyl linoleate (6),ethyl palmitate (7),daucosterol (8),β-sitosterol (9),(6S,9R)-roseoside (10),soya-cerebroside Ⅰ (11),dibutyl phthalate (12),4,4'-diphenylmethane-bis (methyl) carbamates (13).CONCLUSION All the compounds are isolated from this plant for the first time.
