Abstract
Objective:
To study the chemical constituents of the ethyl ether extract of the Leptopus chineseis.
Methods:
The chemical constituents were isolated by means of chromatography and identified by spectra data and physicochemical characters.
Results:
Three compounds were isolated and identified as friedelane-2alpha, 3beta-diols (1), betulinic acid (2) and 3beta-O-trans-coumaroylbetulinic acid (3).
Conclusion:
The compounds are isolated from Leptopus chineseis for the first time.
