Chemical constituents of Sparganium stoloniferum (Ⅰ) / 中草药

ABSTRACT

Objective To study the chemical constituents in Sparganium stoloniferum. Methods The compounds were isolated by repeated silica gel and Sephadex LH-20 chromatographies. The structures of isolated compounds were identified by analysis of their spectral data and chemical reactions. Results Nine compounds were isolated and their structures were identified as daucosterol palmitate (Ⅰ), ?-sitosterol palmitate (Ⅱ), 24-methylenecycloartanol (Ⅲ), 6, 7, 10-trihydroxy-8-octadecenoic acid (Ⅳ), vanillic acid (Ⅴ), p-hydroxybenzaldehyde (Ⅵ), 2,3-dihydroxypropyl palmitate (Ⅶ), 5-hydroxymethyl-2-furaldehyde (Ⅷ), ?-sitosterol (Ⅸ). Conclusion Compounds Ⅰ-Ⅲ and Ⅴ-Ⅷ are obtained from the plants of Sparganium L. for the first time.
