This work describes the semi-synthesis of derivatives from derris isoflavone-A (1), scandenin (2) and 6,8-diprenyl-4′,5,7-trihydroxy isoflavone (3) which are major constituents isolated from chloroform extract of Derris scandens Benth. All the semi-synthesized derivatives (4-11) were characterized by NMR and mass spectroscopic techniques. All these derivatives are evaluated for their antifeedant activity
这项工作描述了鱼藤异黄酮-A (1)、鱼藤素 (2) 和 6,8-二异戊二烯基-4',5,7-三羟基异黄酮 (3) 衍生物的半合成,这些衍生物是从鱼藤氯仿提取物中分离出来的主要成分。德里斯扫描了本斯。所有半合成衍生物(4-11)均通过核磁共振和质谱技术进行表征。使用非选择实验室生物测定法评估所有这些衍生物对蓖麻半翅虫和烟草毛虫的拒食活性。结果表明,scandenin (2)、化合物 5、7 和 10 具有有效的杀虫活性。
