Chemical Composition and Antimicrobial Activity of the Essential Oils of Artemisia scoparia and A. capillaris

Abstract

The chemical composition of the essential oils obtained from Artemisia scoparia Waldst. et Kitamura and Artemisia capillaris Thunb. was analyzed by GC/MS. The essential oil of A. scoparia was rich in camphor (11.0 %), 1,8-cineole (21.5 %), and β-caryophyllene (6.8 %) as the major compounds, whereas A. capillaris oil was rich in β-pinene (9.4 %), β-caryophyllene (11.1 %), and capillene (32.7 %). The essential oils and some of their major compounds were tested for their antimicrobial activity against 15 different genera of oral bacteria. The essential oils of A. scoparia and A. capillaris exhibited considerable inhibitory effects against all oral bacteria tested, while their major components demonstrated various degrees of growth inhibition.
