摘　　要：以烟草赤星病菌为供试靶标,采用孢子萌发及生长速率测定法,对华山姜、毗黎勒、团花树和金钮扣的95%乙醇粗提物进行了抑菌活性测定。结果表明:在终浓度为200μg/mL下,华山姜对该菌的孢子萌发及菌丝生长的抑制率最高,分别为72%、53%,其次为毗黎勒。团花树和金钮扣只对该菌的孢子萌发有低抑制活性。因此,华山姜对烟草赤星病菌孢子萌发及菌丝生长的抑制效果显著优于另外3种提取物,与75%百菌清WP阳性对照在相同浓度下达到同一显著水平。Using Alternaria alternata as the trail target, the antifungal activity of 95 % ethanol crude extract from Alpinia chinensis, Terminalia bellirica ,Anthocephalus chinensis , Spilanthes paniculata were studied by the spore germination and growth rate method. The results showed that Alpinia chinensis had the highest inhibitory rate for spore germination and mycelial growth,the inhibition rate were 72% and 53% respectively at the concentration of 200 μg/mL, followed by Terrninalia bellirica. The extracts of Anthocephalus chinensis and Spilanthes paniculata only had low inhibitory activities against the spores of Alternaria alternata. Therefore,at the same concentration,the extract of Alpinia chinensis showed equivalent strong inhibitory effects with the positive control of 75% Chlorothalonil WP, and significantly stronger than the other three extracts.
