对新疆西部产薰衣草精油进行了化学成分分析和离体抗植物病原真菌活性测定。GC-MS分析共确认薰衣草精油29种化学组分,其主要化学成分为芳樟醇(33.16%)和乙酸芳樟酯(32.64%),根据莰酮的低含量(0.33%)和石竹烯(7.13%)等倍半萜的高含量特性,确定新疆主栽薰衣草品种为英国薰衣草(Lavandula angustifolia)。薰衣草精油表现出较强的抑制植物病原真菌活性,对棉花枯萎病菌、小麦赤霉病菌、烟草赤星病菌和番茄早疫病菌菌丝生长抑制作用的最低有效浓度(MEC)分别为1.0,0.5,0.125,0.25μl/ml。
The chemical composition of the lavender essential oil produced in the western part of Xinjiang was analyzed and the activity of the anti-plant pathogenic fungi was determined. GC-MS analysis confirmed 29 chemical components of lavender essential oil. Its main chemical components were linalool (33.16%) and linalyl acetate (32.64%), based on the low content of fluorenone (0.33%) and caryophyllene ( 7.13%) High content characteristics of equal sesquiterpenes. It was determined that the main lavender species in Xinjiang is Lavandula angustifolia. Lavender oil showed strong inhibition of phytopathogenic fungi activity, and the minimum effective concentrations (MEC) of the mycelial growth inhibition of Fusarium oxysporum f. sp., Fusarium oxysporum f. sp., Aspergillus fuminum, and Aspergillus oryzae were 1.0, 0.5, 0.125, respectively. , 0.25 μl/ml.
