| 摘 要： | 采用试管稀释法和管碟法分别研究了金荞麦(Fagopyrum dibotrys )根状茎和茎叶不同溶剂提取物对6种细菌和13种真菌的体外抑菌作用。结果显示,金荞麦对细菌和真菌均有一定的抑制作用。对细菌的抑菌效果表明:各种提取物对金黄色葡萄球菌、大肠杆菌、枯草芽孢杆菌、苏云芽孢杆菌、卡拉双球菌都有明显的抑菌作用,但是对5406放线菌只有根乙醇提取物和茎叶水提取物有一定的抑制效果。对真菌的抑菌效果表明:各种提取物对鞭毛菌、白色念珠菌、松赤枯病菌、玉米纹枯病菌、油菜菌核病菌、玉米弯胞杆菌、小麦赤霉病菌、绿色木霉都有明显的抑菌作用。

| Abstract: | The tube broth method and the cup-plate method were adopted to study antimicrobial activity in vitro of the extracts from Fagopyrum dibotrys.The results suggested that F.dibotrys extracts have strong antibacterial action in vitro,and the extracts have high inhibition on Staphylococcus aureus,Escherichia coli,Bacillus subtilis,Bacillus thuringiensis,Diplococcus catarrhalis,Sclerophthora macrospora,Candida albicans,Pestalotia funereal,Rhizoctonia solani,Sclerotinia sclerotiorum,Curvularia lunata(Walk) Boed,Gibberelle zeae(Schw) and Trichoderma viride. |
