[Chemical constituents of Tetrastigma hemsleyanum Diels. et Gilg].

OBJECTIVE

To investigate the chemical constituents of Tetrastigma hemsleyanum.

METHOD

Compounds were separated by rechromatography on silica gel from the chloroform solubles of its ethanol extracts, and the structures were determined by spectral analysis and chemical evidence.

RESULT

Three compounds were isolated and elucidated as 6'-O-benzoyldaucosterol, daucosterol and beta-sitosterol.

CONCLUSION

All the three compounds were isolated from this plant for the first time, of which 6'-O-benzoyldaucosterol is a new natural product.
