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 triperpene 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 to Neotermes dalbergiae species. In constrast these compounds were less toxic to Cryptotermes cynocephalus species.
