fumarates and 2-furoic-acid

To study the chemical constituents from the ethyl acetate extracts of Cremastra appendiculata.. The compounds from the ethyl acetate extracts were isolated by the silica gel column and Sephadex LH-20 column chromatography, their structures were elucidated by the spectral analysis and chemical evidence.. Seven componds were separated and identified as fumaric acid (1), dimethylhexyl phthalate (2), L-pyroglutamic acid (3), 2-furoic acid (4), vanillic acid (5), p-coumaric acid (6), protocatechuic acid (7).. Compounds 1 to 6 are obtained from this plant for the first time.
