| Summary: | The bark of Albizia lebeckioides and Albizia falcataria have been examined for their chemical
constituents. A. lebeckioides has yielded the steroidal ketone, stigmasta-4,22-dien-3-one, and a triterpene alcohol
as the major neutral components. A. falcataria has yielded a similar triterpene and fatty ester as its major
constituents. The toxicity of the compounds was evaluated in bioassay against termites.
The results showed that lupenone and stigmastadienone were toxic ioNeotermes dalbergiae species. In
contrast these compounds were less toxic to Cryptotermes cynocephalus species.
