Chemical composition and antimicrobial activity of Clausena indica (Dalz) Oliv. (Rutaceae) essential oil from Vietnam

Abstract

The essential oil obtained from the branches and leaves of Clausena indica (Dalz) Oliv. (Rutaceae) has been analyzed by GC/MS. Fifty-three components of the essential oil, representing 96.9% of the total amount, were identified. The main constituents were myristicin (35.3%), terpinolene (16.7%), and δ-3-carene (11.3%). The essential oil was screened for antimicrobial activity, showing positive results against some bacterial strains. Moreover, a comparison between constituents of C. indica essential oil with the ones reported in the literature for other Clausena ssp. is pointed out and some chemotaxonomic considerations have been identified.
