Four pyrocatechol derivatives and two flavone glycosides were isolated from a methanol extract of the fruits of Messerschmidia argentea, in addition to two pyrrolidizine alkaloids, hydrocarbons, and fatty acid methyl esters. These pyrocatechol derivatives were identified as methyl caffeate, methyl 3, 4-dihydroxybenzoate, methyl 2-(3,4-dihydroxyphenyl) acetate, and rosmarinic acid, these flavone glycosides as kaempferol 3-O-B-D-glucopyranoside and quercetin 3-O-B-glucopyranoside, and the alkaloids as 3'-acetylindicine and indicine, respectively, by spectroscopic methods. It is found that the hydrocarbons and the fatty acid methyl esters were mainly composed of tricosane and methyl linoleate, respectively.
