title: Trinervitene diterpenes from soldiers of two Nasutitermes species from French Guyana.
abstract: 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.
