| 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. |
