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).

摘要

采用水蒸馏法从绵毛胡麻地上部分的挥发性成分中提取，并用 GC 和 GC/MS 进行分析。分析鉴定了 68 种成分，其中含量较高的有香叶异戊酸酯（18.93%）、月桂酸（12.07%）、大根香叶烯 D（10.61%）、癸酸（8.07%）、6,10,14-三甲基-2-十五烷酮（5.02%）和 1-己醇（4.99%）。该植物的分离精油对革兰氏阳性菌（蜡样芽孢杆菌 ATCC11778、粪肠球菌 ATCC 29212 和金黄色葡萄球菌 ATCC 2923）具有较高的抗菌活性，对革兰氏阴性菌（大肠杆菌 ATCC 25922、粪肠球菌 ATCC 13048 和肺炎克雷伯菌 ATCC 10031）也具有中等抗菌活性。
