Abstract：Aiming to find out the functional components and track their molecular structures in the leaves of Weixian radish,this research adopted the silica gel column chromatography,Sephadex LH -20 and RP -18 chromatographic separation and purification technique to analyze the methanol extract.Total of 18 kinds of components were seperated and purified,which were mustard acid glyceride,sinapine thiocyanate,β-sitos-terol,γ-sitosterol,glucoraphanin,daucostedienoic acid,hexadecylenic acid,vaccenic acid,myristic acid, linum cerebroside,octadecanoic acid and eicosanoic acid.The linum cerebroside was the one first obtained from plant,and its molecular structure was identified through physical and chemical analysis and spectral methods such as MS and NMR.The sulforaphene has important biological activity,so the tests on its inhibition to Escherichia coli and Staphylococcus aureus were also carried out at the same time.It indicated that 1 mg/mL sulforaphene showed significant inhibiton effects on Escherichia coli and Staphylococcus aureus.
