Title: Chemical constituents of Physalis pubescens
Abstract: Chemical constituents of 95% ethanol extract of the dried persistent calyx of Physalis pubescens were investigated. By chromatography on a silica gel column and reverse-phase preparative HPLC,10 compounds were isolated from the dichloromethane fraction. Based on the MS and 1D /2D NMR data,these compounds were identified as 5-O-( E-feruloyl) blumenol( 1),isovanillin( 2),( E)-ethyl 3-( 4-hydroxyphenyl) acrylate( 3),4-hydroxybenzaldehyde( 4),4-methylphenol( 5),( E)-methyl cinnamate( 6),7,3',4'-trimethoxyquercetin( 7),5,3',5'-trihydroxy-3,7,4'-trimethoxyflavone( 8),danielone( 9),and 5,5'-diisobutoxy-2,2'-bifuran( 10).Compound 1 was a new one,while compounds 7-10 were obtained from the genus Physalis for the first time.
