Abstract
A complex of 5-hydroxypyrrolidin-2-one and pyrimidine-2,4-dione was isolated from the leaves of Jatropha curcas L. by extraction with ethyl acetate and subsequent fractionation of the extract by column chromatography on Sephadex LH20, silica gel and fractogel TSK HW 40. Final purification was carried out by HPLC on a preparative RP-18 column and the structure was proposed mainly by mass spectrometry, H-1- and C-13-NMR. (C) 1998 Elsevier Science Ltd.
