Composition and Antimicrobial Screening of the Essential Oil of Acantholippia deserticola (Phil.ex F.Phil.) Moldenke

摘要

The composition of the essential oil from Acantholippia deserticola (Phil,ex F.Phil.) Moldenke (Verbenaceae) obtained by hydrodistillation of the aerial parts was examined by GC,GC/MS and NMR.Twenty-two compounds were identified representing 98.9% of the total oil.alpha-and beta-Thujone were characterized as the main constituents,10.5% and 77.9%,respectively.Furthermore,the oil was tested for its antimicrobial activity using a micro-dilution assay exhibiting no inhibition on human pathogenic bacteria and yeast.
