Chemical component studies on the leaf and inflorescence essential oil of Hyptis brevipes (Poit.)

摘要

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.
