Abstract
以仁果丛梗孢(Moniliafructigena)、串珠镰刀菌(Fusariummoniliforme)、瓜果腐霉(Pythiumaphani-dermatum)、禾谷镰刀菌(Fusariumgraminearum)、致病疫霉(Phytophthorainfestans)、尖孢镰刀菌(Fusariumox-ysporum )为供试菌,采用生长速率法和液体培养法对丹参、黄岑、半夏、仙人掌、蒲公英、荆条6种药用植物浸提物的离体活性进行测定.结果表明:3种溶剂中,丙酮粗提物的抑菌活性最高,平均抑菌率达72.9%.在生药浓度为0.1 g/mL时,丹参对6种供试菌种均有抑制作用,尤其对仁果丛梗孢(M.fructigena)有明显的抑制作用,其菌落的生长抑制率和菌丝生长的抑制率分别可达87.1%和100%,其余5种药用植物粗提物对6种供试菌种的抑制作用均不明显.
