[Studies on the chemical constituents from the leaf of Liquidambar formosana Hance].
OBJECTIVE
To study the chemical constituents from the methanolic extract from the leaf of Liquidambar formosana Hance.


METHODS
The compounds were separated with the column chromatographic and Prep HPLC, and their structures were identified by chemical and spectroscopic methods.


RESULTS
Three compounds were isolated from the methanolic extract. They were identified as: beta-sitosterol (I), alpha-amyrin (II) and oleanonic acid (III).


CONCLUSIONS
All of them were isolated from this plant for the first time.
