Abstract:
Objective To study the chemical constituents of Helicia nilagirica. Methods The ethanol extract was seperated by petroleum ether, dichloromethane, and n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical pro-(perties) and spectral analysis. Results Four compounds were isolated from the petroleum ether extract and identified as n-hexadecane acid (Ⅰ), ?-sitosterol (Ⅱ), ?-sitosterol-3-O-?-D-glucoside-6′-acetate (Ⅲ), and daucosterol (Ⅳ). Conclusion All the compounds are isolated from the plant for the first time. Compounds Ⅰ, Ⅲ, Ⅳ are isolated from the plants of Helicia Lour. for the first time, and compound Ⅲ is a new natural product.
