Nine compounds were isolated from Smilax glabra Roxb. Eight of them were identified as quercetin（Ⅱ),tufulingoside (Ⅲ ),succinic acid (Ⅳ),palmitic acid (Ⅴ),stigmasterol-3-O-β-D-glucopyrano (Ⅵ),sitosterol3-O-β-D-glucopyranoside(Ⅶ)and a mixture of stigmasterol (Ⅷ)and β-sitosterol (Ⅸ)by chemical and spectral analysis., was a new compound,its chemical structure was 5, 7-dihydroxyl-chromone-3-α--L-rhamnopyranoside,named tufulingoside. Ⅵ and Ⅷ were found from this plant for the first time. Compound Ⅰ will be reported seperately in a forthcoming article.
