[Chemical constituents of Physalis pubescens].
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).
