Abstract
The salivary defensive secretion of large soldier termites of the species P seudacanthotermes spiniger contains two novel macrocyclic lactones [22-keto -hexacosanolide (2) and 2-hydroxy-24-keto-octacosanolide (3)] together with the already known macrolactone hexacosanolide (1). In addition, the secret ion contains important amounts of a polysaccharide based mainly upon beta-g lucoypyranose, beta-glucosamine and N-acetyl-beta-glucosamine in equal amou nt.
