Two novel triterpenes, 29(20→19)abeolupane‐3,20‐dione ( 4 ) and 19,20‐secoursane‐3,19,20‐trione ( 5 ), besides (3 β )‐3‐hydroxy‐29(20→19)abeolupan‐20‐one ( 2 ), lupenone, and α ‐amyrone ( 6 ), were isolated from the leaves of Ficus microcarpa and were characterized by spectroscopic means, including 2D‐NMR techniques and chemical methods. Compound 4 is the second derivative having the 29(20→19)abeolupane skeleton, and 5 is a novel skeleton. A biosynthetic pathway to 5 is proposed ( Scheme ).
