Objective:
To study the chemical constituents of Pholidota cantonensis.
Method:
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.
Result:
Four compounds were obtained and characterized as pholidonone (1), ephemeranthoquinone (2), orchinol (3), batatasin III (4).
Conclusion:
They have been isolated from this plant for the first time and pholidonone (1) was a new compound.
