Abstract:
Objective To study the chemical constituents of Smilax china.Methods The compounds were isolated by silica gel,Sephadex LH-20,ODS chromatography,and semi-preparative HPLC.Their structures were elucidated on the basis of MS and NMR spectroscopic analyses.Results Seven flavonoids and four stilbenes were isolated and identified as dihydrokaempferol-5-O-?-D-glucoside(Ⅰ),engeletin (Ⅱ),isoengeletin(Ⅲ),dihydroquercetin-3-O-glycoside(Ⅳ),3,5,7,3',5'-pentahydroxy-flavanonol (Ⅴ),astilbin(Ⅵ),quercetin-3'-Oglycoside(Ⅶ),piceid(Ⅷ),scirpusin A(Ⅸ),resveratrol(Ⅹ),and oxyresveratrol(Ⅺ).Conclusion CompoundsⅣ—Ⅸare isolated from this plant for the first time,among which the ~(13)C-NMR data of compoundⅨis reported firstly.
