Abstract

Two new aliphatic constituents, characterized as 6-methyl tritriacont-5-on-28-ol and 8-methyl hentriacont-3-ene, have been isolated for the first time form the fruit rind of Momordica dioical along with the known sterol pleuchiol. Momodicaursenol, an unknown pentacyclic triterpene isolated from the seeds, has been identified as urs-12, 18(19)-dien-3β-ol on the basis of spectral data analyses and chemical means.
