[Chemical constituents from herb of Pholidota cantonensis].
OBJECTIVE
To study the chemical constituents of Pholidota cantonensis.


METHODS
The compounds were isolated and purified on silica gel, Sephadex LH-20, Chromatorex ODS column chromatography and the structures were determined based on the spectral and chemical evidences.


RESULTS
Four compounds were obtained and characterized as pholidonone (1), ephemeranthoquinone (2), orchinol (3), batatasin III (4).


CONCLUSIONS
They have been isolated from this plant for the first time and pholidonone (1) was a new compound.
