[Chemical constituents from Salix oritrepha Schneid].

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.
