Abstract

Four new compounds named (3E,7Z,11E)-19-hydroxycasba-3,7,11-trien-5-one (1), 6α-hydroxy-10β-methoxy-7α,8α-epoxy-5-oxocasbane-20,10-olide (2), 15α-hydroxylup-20(29)-en-3-one (3), and (2R,4aR, 8aR)-3,4,4a,8a-tetrahydro-4a-hydroxy-2,6,7,8a-tetramethyl-2-(4,8,12-trimethyltridecyl)-2H-chromene-5,8-dione (4) were isolated from the MeOH extracts of the aerial parts of Ricinus communis L. by chromatographic methods. Their structures were elucidated by extensive spectroscopic experiments.
