Studies on the chemical constituents of Heterosmilax japonica

OBJECTIVE To investigate the chemical constituents of Heterosmilax japonica. Kunth.METHODS The compounds were separated with chromatography and their chemical structures were elucidated by means of IR,MS,¹H-NMR,and ¹³C-NMR spectral method respectively.RESULTS Nine compounds were isolated from the plant.They were identified as palmaitic acid(Ⅰ),α,α′-[bis-5-formyl-2-furanyl]dimethyl ether(Ⅱ),p-hydroxybenzoic acid(Ⅲ),rhein(Ⅳ),β-sitosterol-3-O-β-D-glucoside(Ⅴ),β-sitosterol(Ⅵ),glycerol monopalmitate(Ⅶ),behenic acid(Ⅷ)and octacosane(Ⅸ).CONCLUSION The compoundsⅡ,Ⅲ,Ⅳ,Ⅴ,Ⅶ,Ⅷ and Ⅸ were isolated from the plant for the first time.
