Summary
The defense secretion of the nasute termiteBulbitermes singaporensis consists of 1 new and 2 known tetracyclic diterpenes, spectrometrically identified as 14α-acetoxy-6,8-kempadien-3-one, 3α, 14α- and 3β, 14α-diacetoxy-6,8-kempadiene. The presence of these compounds supports the kinship of the oriental ‘constricted-head’ genera withNasutitermes species in the Philippines and in East Africa.
