Abstract
The volatile constituents of the aerial flowering parts of Linum pubescens were collected by hydro-distillation and analysed by GC and GC/MS. Analysis allowed the identification of 68 components of which, geranyl isovalerate (18.93%), lauric acid (12.07%), germacrene D (10.61%), decanoic acid (8.07%), 6,10,14-trimethyl-2-pentadecanone (5.02%) and 1-hexanol (4.99%) were detected as major constituents. The isolated essential oil of the plant exhibited high antimicrobial activity against Gram-positive bacteria (Bacillus cereus ATCC11778, Enterococcus faecalis ATCC 29212 and Staphylococcus aureus ATCC 2923) and showed moderate antimicrobial activity against Gram-negative bacteria (Escherichia coli ATCC 25922, Enterococcus faecalis ATCC 13048 and Klebsiella pneumoniae ATCC 10031).
