[Studies on chemical constituents of Heliciopsis lobata II].
OBJECTIVE
To study the constituents of the leaves of Heliciopsis lobata.


METHODS
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.


RESULTS
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).


CONCLUSIONS
All of these compounds were isolated from genus Heliciopsis for the first time.
