[Studies on chemical constituents of Alpinia jianganfeng].
OBJECTIVE
To study the chemical constituents of Alpinia jianganfeng (Zingiberaceae) distributed in Sichuan province.


METHODS
Chromatography and spectral analyses were used to isolate the constituents and elucidate their structure.


RESULTS
Four compounds were isolated from the rhizome of A. jianganfeng and elucidated as kaempferol-3-O-glucuronide(1), docosanoic acid(2), 3-hydroxy-stigmast-5-en-7-one(3) and beta-sitosterol(4).


CONCLUSIONS
All these compounds were obtained from this plant for the first time.
