Title: Study on Chemical Constituents of Cuscuta chinensis Lam
Abstract: OBJECTIVE To study the chemical constituents of the aerial parts of Cuscuta chinensis Lam.METHODS The chemical constituents of Cuscuta chinensis Lam were isolated and purified by silica gel,LH-20 column chromatography and preparation HPLC,etc.Their structures were identified by means of spectra comparison with authentic samples.RESULTS Ten compounds were obtained and identified as 5,3′-dihydroxy-3,6,7,4′-tetramethoxy flavone(Ⅰ),5,3′-dihydroxy-6,7,4′-tritermethoxy flavone(Ⅱ),5,7,3′-triterhydroxy-6,4′-dimethoxy flavone(Ⅲ),quercetin(Ⅳ),hyperoside(Ⅴ),kaempferol(Ⅵ),5,7,3′-triterhydroxy-4′-methoxy flavone(Ⅶ),luteolin(Ⅷ),3-methoxy-chrysoeriol-4′-O-β-D-glucoside(Ⅸ),and luteolin-7-O-β-D-glucopyranoside(Ⅹ).CONCLUSION Compounds Ⅰ,Ⅱ,Ⅲ,Ⅶ,Ⅸ and Ⅹare isolated from this plant for the first time.
