| 摘 要： | 用生长速率测定法以红景天立枯病菌(Rhizoctonia solani Kuhn)为供试靶标,对8种有毒植物的20种不同粗提取物进行了抑菌活性测定.结果表明:在0.2 mg·mL-1浓度下,藜芦碱(1)的抑制率最高为91.67%,其次藜芦碱(2)、藜芦(非生物碱)、曼陀罗(石油醚)、延胡索(生物碱)、雷公藤(其它成分)5种供试药剂的抑制率也都超过了80%.说明本研究中的这6种药剂对红景天立枯病菌具有一定的生物活性.

| Abstract: | Using Rhizoctonia solani Kuhn as the trail target and the growth rates method to test the antifungal activity that 20 kinds of different crude extract from 8 kinds of poisonous plants.The results showed that:at the concentration of 0.2 mg · mL-1,veratrine(1) had the highest inhibitory rate 91.67%,the inhibitory rate were more than 80% were veratrine(2),Veratrum(un-alkaloid),stramonium(petroleumether),corydalis(alkaloid),and tripterygium(other ingredients).The 6 kinds of pharmacy in this study have some biological activity. |
