摘要
目的研究我国传统药用植物抗烟草花叶病毒(tobacco m osa ic v irus,TM V)的作用,为从植物中开发抗病毒类生物农药提供依据。方法采用局部枯斑法和叶碟法对我国78科162种药用植物提取物的抗TM V侵染和增殖作用进行测定。结果在10 m g/mL水平下,19种植物提取物可有效抑制TM V侵染,9种植物提取物有明显抑制TM V增殖作用。结论大多数药用植物提取物具有一定抗TM V侵染活性,仅少数药用植物提取物有较好的抗TM V增殖作用。
Objective To study antiviral activities of medicinal plant extracts against tobacco mosaic virus （TMV） and provide basis for exploitation of bio-pesticides from plant resource. Methods Using local lesion and leaf discs assay, extracts from 162 medicinal plant species belonging to 78 families in China were screened for antiviral activity against TMV. Results At a concentration of 10 mg/mL, extracts of 19 plant species could effectively inhibit TMV infection; nine plant extracts significantly inhibited the multiplication of TMV in infected leaf discs. Conclusion Most of the plant extracts exhibits certain antiviral activity of inhibiting TMV infection, but only a few have inhibitory effect on TMV multiplication.
