摘要

We studied the effect of aqueous extracts of Azadirachta indica, Calotropis procera, Cleistanthus collinus, Dalbergia sissoo, Datura inoxia and Lantana camara on induction of peroxidase (POD) and catalase (CAT) in cucumber and chilli seedlings. The extract of C. collinus, exhibited a profound effect by inducing maximum activity of POD and CAT in both the crop species. Therefore, we fractionated the extract of C. collinus over silica gel column using 90%, 45% and 0% aqueous methanol. The fraction eluted by 90% methanol (fraction 1) showed bioactivity by inducing POD and CAT activity. Also, the extract of C. collinus and fraction 1 modulated the isozyme profile of both the enzymes. In addition, they also increased H2O2 content in the seedlings, suggesting the triggering of defence mechanism in the seedlings. The findings of the present study suggest the possibility of developing an organic crop protection agent using C. collinus.

Collines的提取物，通过在作物物种中诱导豆荚和猫的最大活性表现出深刻的影响。 因此，我们使用90％，45％和0％的甲醇水溶液在硅胶柱上分离C. Collinus的提取物。 通过诱导豆荚和猫活性，将90％甲醇（级分1）洗脱的级分溶液显示出生物活性。 此外，C. Collinus和Fractact 1的提取物调节了两种酶的同工酶谱。 此外，它们还增加了幼苗中的H 2 O 2含量，表明幼苗中的防御机制触发。 本研究的发现表明，使用C. Collinus开发有机作物保护剂的可能性。
