• Sesquiterpene alcohol
• Cordia verbenacea
• alpha-bisabolol
• NMR

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 alpha-bisabolol, a sesquiterpene alcohol with important biological properties. NMR analyses (H-1, C-13, DEPT-135, COSY, HMQC and HMBC) comparing the purified compound with alpha-bisabolol compound revealed that the new alcohol is an isomer structural of alpha-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.
