Abstract
Objective:
To study the chemical constituents of Ervatamia hainanensis.
Method:
The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR.
Result:
Five compounds were identified as I (isolariciresinol 9-O-beta-D-glucopyranoside), II (cycloartenol), III (beta-amyrin acetate), IV (beta-sitosterol), V (daucosterol), respectively.
Conclusion:
All the compounds were isolated from this plant for the first time.
