Bioactivity-guided fractionation of a CHCl3 extract of Stizophyllum riparium has afforded six new compounds, namely, the triterpene esters, 3.beta.-hydroxy-24-trans-ferulyloxyurs-12-en-28-oic acid [1], 3.beta.-hydroxy-24-cis-ferulyloxyurs-12-en-28-oic acid [2] 3.beta.-,19-dihydroxy-24-trans-ferulyloxyurs-12-en-28-oic acid [3], and the pregnane derivatives, 2.alpha.,3.beta.,12.beta.-trihydroxypregna-4,7,16-trien-20-one [4], 2.alpha.,3.beta.,12.beta.-trihydoxypregna-4,7-dien-20-one [5] and 16.alpha.-methoxy-2.alpha.,3.beta.,12.beta.-trihydroxypregna-4,7-dien-20-one [6]. The structures of these isolates were established by spectroscopic and chemical methods. Compounds 1, 2, and 4 exhibited cytotoxic activity against the P-388 lymphocytic leukemia test system in cell culture.
