Abstract

Hyptis brevipes Poit. leaf and inflorescence essential oils obtained by hydrodistillation, were analyzed by gas chromatography mass spectroscopy (GC-MS). Fifty seven components were identified in the leaf oil. The major componentsgermacrene D (13.54%), caryophyllene (12.31%), phthalamide doxime (9.47%) and caryophyllene oxide (8.57%). Thirty seven components were identified in inflorescence oil with the main components being in caryophyllene oxide (45.09%), 1,5,5,8-tetramethyl-12-Oxabicyclo [9.1.0] dodeca-3,7-diene (4.95%), caryophyllene (4.79%) and a-bourbonene (4.20%). The compositions of both oils varied qualitatively and quantitatively.

 

Key words: Hyptis brevipes, essential oil, GC-MS analysis, germacrene D, caryophyllene oxide.
