[Chemical constituents of Pistia stratiotes L].
OBJECTIVE
To investigate the chemical constituents of Pistia stratiotes, a kind of duckweed.


METHODS
Compounds were separated by chromatography on sillica gel, and their structures were identified by spectral analysis and chemical evidence.


RESULTS
Four compounds were obtained and identified as stigmasta-4,22-dien-3-one, stigmasterol, stigmasteryl stearate and palmitic acid.


CONCLUSIONS
All the four compounds were isolated from this plant for the first time.
