Objective:
To study the chemical constituents in the rhizome of Elaeagnus bockii.
Method:
Compounds were isolated by silica gel and Sephadex LH-20 chromatography. Their structures were elucidated by means of spectral analysis.
Result:
Seven compounds were isolated from the rhizomes of E. bockii, and their structures were identified as angelicin (1), psoralen (2), vanillic acid (3), bakuchiol (4), oleanolic acid (5), ursolic acid (6) and beta-sitosterol (7 ).
Conclusion:
All these compounds were obtained from E. bockii for the first time.
