[A study on chemical components of Tetrastigma hemsleyanum Diels et Gilg. Native to China].
OBJECTIVE
To investigate the chemical constituents of Tetrastigma hemsleyanum native to China.


METHODS
Compounds were separated by column chronatography with silica gel and elucidated by chemical evidence and spectral analysis.


RESULTS
Four compounds were isolated from the petroleum ether extract. Their structures were identifies as taraxerone, taraxerol,beta-sitosterol and ergosterol.


CONCLUSIONS
