Trinervitene diterpenes from soldiers of two Nasutitermes species from French Guyana.
Methanolic extracts of soldiers of Nasutitermes guayanae and N. surinamensis have been shown to contain complex mixtures of diterpenes and monoterpenes. Eighteen diterpenes have been isolated and identified; twelve of them are previously known nasute termite diterpenes, while six are new trinervitene diterpenes. 2alpha,9beta-Dihydroxy-3beta,8beta-oxido-1(15)-trinervitene has been isolated from N. guayanae, while 3alpha,14alpha-diacetoxy-2beta-hydroxy-1(15),8(19),9-trinervitatriene, 14alpha-acetoxy-2beta,3alpha-dihydroxy-1(15),8(19),9-trinervitatriene, 2beta,3alpha-diacetoxy-11beta,14alpha-dihydroxy-1(15),8(19)-trinervitadiene, 9alpha,14alpha-diacetoxy-2beta,3alpha-dihydroxy-1(15),8(19)-trinervitadiene, and 2beta,9alpha,14alpha-triacetoxy-3alpha-hydroxy-1(15),8(19)-trinervitadiene have been isolated from N. surinamensis. Their structures were determined on the basis of their spectroscopic properties.
