[Saponins from roots of Stephanotis mucronata].
OBJECTIVE
To study the chemical constituents from n-BuOH fraction of the roots of Stephanotis mucronata.


METHODS
The compounds were separated by chromatographic methods. A combination of UV, MS, and NMR spectroscopic methods was applied to identify structure of these compounds.


RESULTS
Four oleane saponins were isolated and identified as sitakisoside VII (1), sitakisoside VI (2), sitakisoside II (3), and sitakisoside I (4).


CONCLUSIONS
These four compounds were obtained for the first time from this plant.
