ABSTRACT
Chemical investigation of fruits of Mours alba L. lead to the isolation of fifteen compounds by various chromatographies such as silica gel, Sephadex LH-20, RP-C18 column chromatography. Their structures were determined to be 1-[5-(2-formlfuryl) methyl] dihydrogen 2-hydroxypropane-1, 2, 3-tricarboxylate 2, 3-diethyl ester (1), 1-[2-(furan-2-yl)-2-oxoethyl] pyrrolidin-2-one (2), divaricataester A (3), methyl 1-[2-(furan-2-yl)-2-oxoethyl]-5-oxopyrrolidine-2-carboxylate (4), 1-[2-(furan-2-yl)-2-oxoethyl]-5-oxopyrrolidine-2-carboxylic acid (5), L-pyroglutamic acid (6), L-pyroglutamic acid ethyl ester (7), 3-O-caffeoylquinic acid methyl ester (8), 3-O-caffeoylquinic acid ethyl ester (9), 5-O-caffeoylquinic acid methyl ester (10), 5-O-caffeoylquinic acid ethyl ester (11), 4-O-caffeoylquinic acid methyl ester (12), 4-O-caffeoylquinic acid methyl ester (13), 4-O-caffeoylquinic acid (14), 3-O-caffeoylquinic acid (15), respectively, based on the spectral analysis such as NMR, MS etc. Compounds 1-14 were isolated from this genus for the first time, among which 1 was a new compound.
