[Triterpenoids and steroids of root of Rubus biflorus].
Zhong Yao Cai. 2008 Nov; 31(11):1669-71.ZY

Abstract

OBJECTIVE

To investigate the chemical constituents of root of Rubus biflorus.

METHODS

Isolation and purification were carried out by silica gel column chromatography and recrystallization and so on. Structural determination of the pure compounds was based on physico-chemical properties and various spectral data analysis (1H-NMR, 13C-NMR, IR, EI-MS).

RESULTS

Five compounds were isolated and identified as follows: lupeol acetate (I), corosolic acid (II), oleanic acid (III), 2alpha-hydroxyoleanolic acid (IV), sitosterol (V).

CONCLUSION

All these compounds are isolated from this plant for the first time.
