| Abstract: |
| Component extracted from Buxus microphylla with Chloroform was separated and purified through the silica gel column chromatography,from which nine compounds were isolated and identified as:β-sitosterol(I),stigmasterol(II),daucosterol(III),salicylic acid(IV),homovanillic acid(V),5,4'-dihydroxy-3,3',7-trimethoxy-flavonoids(VI),5,4'-dihydroxy-3,3',6,7-tetracarboxylic oxygen-flavonoids(VII),Cleomiscosin A(VIII),3,5-dihydroxy-4',6,7-trimethoxy-flavone-3'-O-β-D-Gluoside(Ⅸ). Compounds IV,V,VI,VII were isolated from the plant for the first time. |
