Study on Root Chemical Constituents of Smilax Scobinicaulis

Zhao Shi-huan

Abstract

Objective:To study the chemical constituents of the fat-soluble portion of Smilax scobinicaulis C.H.Wright.Method:The fat-soluble portion was isolated and pured by silica gel column chromatography,HP-20 and Sephadex LH-20.Their chemical structures were elucidated by spectral data(1H-NMR、13C-NMR).Result:Seven compounds were isolated from the fat-soluble portion.They were identified as(1)β-sitosterol,(2)2,4-dihydroxy-3,6-dimethylbenzoate,(3)1-O-p-coumaroylglycerol,(4)ursolic acid,(5)blumenol A,(6)clemaphenolA,(7)1-O-feruloylglycerol.Conclusion:Compounds 2~7 were isolated from this plant for the first time.
