[Study on triterpenes of Microtropis tiflora].
OBJECTIVE
To study the chemical constituents of Microtropis triflora.


METHODS
The compounds were isolated by chromatography on silica gel and Sephadex LH-20. There structures were elucidatedby by chemical methods and spectral analysis.


RESULTS
Five triterpenoids were isolated and elucidated as friedelin (1), 3-oxo-28-friedelanoic acid (2), 29-hydroxy-3-friedelanone (3), salaspermic acid (4), orthosphenic acid (5).


CONCLUSIONS
Compounds 1-5 are all isolated from M. triflora for the first time.
