摘    要:采用水蒸气蒸馏法提取的大蒜精油经GC MS测定,其主要成分为含硫化合物.高质量浓度 (1mg·mL-1以上 )的大蒜精油对烟草花叶病毒(TMV)有一定的体外抑制作用,质量浓度小于 0. 5mg·mL-1的大蒜精油对TMV的体外抑制效果不明显.在离体条件下,大蒜精油对TMV的增殖有明显的抑制作用.在烟草上喷施大蒜精油可降低烟草体内病毒的含量,减轻病害症状.

关 键 词:大蒜  精油  烟草花叶病毒  抗病毒

Abstract:Volatile oil was extracted from Allium sativum by steam distillation and its main component detected by GC-MS was sulphide. Volatile oil could inhibit infectivity of Tobacco mosaic virus (TMV) at high mass concentration (above 1 mg·mL~(-1)), but its inhibiting effect was not apparent when its mass concentration was lower than 500 μg·mL~(-1), it also could inhibit multiplication of TMV in infected leaf discs. Spraying volatile oil to Nicotiana tobacum, the mass concentration of TMV in the tobacco could be reduced and the symptom could be alleviated.
Keywords:Allium sativum L    volatile oil  Tobacco mosaic virus  anti-virus
