INVESTIGATION ON CHEMICAL CONSTITUENTS OF THE CHLOROFORM EXTRACT OF THE STEM OF PARAMIGNYA TRIMERA (OLIVER) BURKILL (RUTACEAE)

Abstract

    From the chloroform extract of Paramignya trimera was collected in Ninh Hoa district,Khanh Hoa province, seven phenolic derivatives - methyl 4-hydroxybenzoate (1), methyl p-(E)-coumarate (2), methyl syringate (3), vanillin (4), (E)-methyl 3-(4'-hydroxy-3',5'-dimethoxyphenyl) acrylate (5), methyl ferulate (6), and methyl 4-hydroxy-3-methoxybenzoate(7) were isolated. The structure of these compounds were determined by 1D NMR spectra andcomparison with published data.
