1Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou 730000, Gansu, China.
Abstract
Objective:
To study chemical constituents of the above ground part of Salix oritrepha.
Method:
Using chromatography to isolate compounds and their structure were identified by physical, chemical and spectral techniques.
Result:
Four compounds were isolated and elucidated as beta-sitosterol, beta-sitosteryl-3-O-glucoside, friedelin, luteolin-7-O-glucoside.
Conclusion:
All of them were isolated from S. oritrepha for the first time. Friedelin from the plants of genus Salix for the first time.
