New macrolactones from the defensive salivary secretion of soldiers of the african termite Pseudacanthotermes spiniger
摘要:
The salivary defensive secretion of large soldier termites of the species Pseudacanthotermes 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 secretion contains important amounts of a polysaccharide based mainly upon beta-glucoypyranose, beta-glucosamine and N-acetyl-beta-glucosamine in equal amount.
