Resumen
The principal constituent of the essential oil from the leaves of the Cordia verbenacea plants collected in Minas Gerais, Brazil had a GC retention time similar to that of α-bisabolol, a sesquiterpene alcohol with important biological properties. NMR analyses ( 1H, 13C, DEPT-135, COSY, HMQC and HMBC) comparing the purified compound with α-bisabolol compound revealed that the new alcohol is an isomer structural of α-bisabolol, due to change in relation to the position of the double bond and the methyl group present in the cyclic chain of these compounds.
