Studies on chemical constituents of Heliciopsis lobata II

Objective To study the constituents of the leaves of Heliciopsis lobata. Method Compounds were isolated by column chromatography on silica gel, neutral aluminum oxide and Sephadex LH -20, and their structures were identified by spectroscopic and physicochemical data. Result Seven known compounds were isolated and identified as: myricetin (1), myricitrin (2), syringetin-3-O-beta-D-glucopyranoside (3), medioresinol (4), D-1-O-methyl-myo-inositol (5), hydroquinone (6), and beta-sitosterol (7). Conclusion All of these compounds were isolated from genus Heliciopsis for the first time.
