摘要
采用生长速率法和倍比稀释法测定了8种中药提取物对薏苡(Coix lacroyma-jobi L.var.ma-yuen(Roman.))灰霉病菌(Botrytis cinerea)的生物活性。结果表明,在浓度为1.0 g/mL时,丁香(Eugenia aro-matica Baill)、辛夷(Magnolia biondii Pamp.)、商陆(Phytolacca acinosa Roxb.)提取物对薏苡灰霉病菌抑菌率达100%;北豆根(Menispermum dahuricmn DC.)、萝藦[Metaplexis japonica(Thunb.)Mark.]、甘草(Gly-cyrrhiza uralensis Fisch.)、艾蒿(Artemisia argyi Levl.et Van.)提取物的抑菌率分别为76.3%、76.3%、69.7%、33.8%;天南星(Arisaema amurense Maxim.)提取物对薏苡灰霉病菌没有抑制作用;丁香、辛夷、商陆的最小抑制浓度依次为0.062 5、0.125 0、0.500 0 g/mL。
Fungal inhibitory activity of extracts from 8 Chinese herbal medicines against Botrytis cinerea of Coix lacroyma-jobiL.var.ma-yuen（Roman.） Stapf was determined by growth rate method and double dilution method.Results showed that at the concentration of 1.0 g/mL,the extracts of Eugenia aromatica Baill,Magnolia biondii Pamp.,Phytolacca acinosa Roxb.had 100% inhibition rate.The extracts of Menispermum dahuricmn DC.,Metaplexis japonica（Thunb.） Mark.,Glycyrrhiza uralensis Fisch.,Artemisia argyi Levl.et Van.had 76.3%,76.3%,69.7%,33.8% inhibition rate respectively.Arisaema amurense Maxim.had no inhibition effect.The MIC of the extracts of Eugenia aromatica Baill,Magnolia biondii Pamp.,Phytolacca acinosa Roxb.were 0.062 5 g/mL,0.125 0 g/mL,0.500 0 g/mL,respectively.
