摘要：
Three new (1-3) triterpenoids and one known (4) triterpenoid were isolated from an acid hydrolyzed methanol-soluble extract of the leaves of Abrus precatorius. Their structures were identified as (20S,22S)3beta,22-dihydroxycucurbita-5(10),24-diene-26,29-dioic acid delta-lactone (1), 3-O-[6'-methyl-beta-D-glucuronopyranosyl]-3beta,22beta-dihydroxyolean-12-en-29-oic acid methyl ester (2), 3-O-beta-D-glucuronopyranosylsophoradiol methyl ester (3), and sophoradiol (4) by spectroscopic techniques including 2D NMR.
