摘要: 为筛选出新的对绵腐卧孔菌、绿色木霉和彩绒革盖菌3种常见木材真菌有效的杀菌剂,采用菌丝生长速率法,测定了山苍子油主成分及其衍生物共10种化合物对这3种常见木材真菌的抑制率,建立毒力方程并分析其活性。结果表明: 10种化合物对3种常见木材真菌的生长均表现出一定的抑制作用,而且随着浓度的升高,抑制作用增强;通过10种化合物对3种常见木材真菌的毒力回归分析,并与三唑酮相比较,依次筛选出对绵腐卧孔菌、绿色木霉和彩绒革盖菌的抑制作用最强的分别为柠檬醛1,2-丙二醇缩醛、β-紫罗兰酮和鸢尾酮,其半数有效抑制质量浓度(EC50)依次分别为18.69、23.50和32.21 mg/L。3种真菌分别经柠檬醛1,2-丙二醇缩醛、β-紫罗兰酮和鸢尾酮处理后,菌体细胞膜的相对渗透率发生变化,表明山苍子油活性成分的木材防腐作用与菌体细胞膜遭破坏有关。

Abstract: In order to screen high-effective fungicide against 3 common wood fungi, i.e., Poria vaporaria, Trichoderm aviride and Coriolus versicolor, the antifungal activities of essential oil and derivatives from Litsea cubeba(Lour.) Pers. oil (10 kinds of compounds) were investigated by mycelium growth rate. The toxicity equations of inhibition rates against three fungi were established. The results showed that the ten kinds of compounds exhibited certain antifungal activity, and with the increasing concentration, antifungal activity became stronger. The inhibition effects of the ten compounds on the three wood fungi were respectively analyzed in comparison with the effect of triadimefon. The results showed that the most powerful compounds against Poria vaporaria, Trichoderm aviride, and Coriolus versicolor were citral acetal 1,2-propanediol, beta-iononeand irone, respectively. And their EC50 values were 18.69, 23.50 and 32.21 mg/L, respectively. The cell membranes of three fungi were damaged by citral acetal 1,2-propanediol, beta-ionone and irone. This indicated that, the wood preservation of Litsea cubeba oil was related with the damage of cell membranes of fungi.
