摘要
蕨类植物Cyclosorus interruptus (wild .)的植物化学初步分析H.Itô(细麻科),Christella dentata(野生)(Forssk.)Brownsey et jeremy(麻麻科)和Nephrolepis cordifolia (L.)Presl发现,粗提物中存在生物碱、甾体、单宁、黄酮类、萜类、心苷类、酚类化合物和萜类等次生代谢产物。实验蕨类植物的银纳米颗粒(AgNPs)配方的特征颜色变化和紫外可见光谱证实了纳米颗粒的合成(C. interruptus, C. dentata和N. cordifolia分别为433.50nm, 450.00nm和444.00 nm)。在室内试验中,对粗提物和蕨类植物- agnp (Fe-AgNP)对斜纹夜蛾(Spodoptera litura, Fab.) 3龄幼虫的杀虫性能进行了评价。粗提物和Fe-AgNP配方对羽蛾的发育期、化蛹率、蛹重和羽化率均有显著降低。它们还引起幼虫、蛹和成虫的畸形,这证实了这种植物的杀虫活性。
IMPACT OF PHYTOECDYSONE FRACTIONS OF THE FERNS CYCLOSOROUS INTERRUPTUS, CHRISTELLA DENTATA AND NEPHROLEPIS CORDIFOLIA ON THE BIOLOGY OF SPODOPTERA LITURA (FAB.)
The preliminary phytochemical analysis of ferns viz., Cyclosorus interruptus (Willd.) H.Itô (Theylepteridaceae), Christella dentata (Willd.) (Forssk.) Brownsey et Jermy (Theylepteridaceae), and Nephrolepis cordifolia (L.) Presl revealed the presence of the secondary metabolites like alkaloids, steroids, tannins, flavonoids, terpenoids, cardiac glycosides, phenolic compounds and terpenoids in crude extract. The characteristic colour change and the UV- Vis spectrum obtained for the silver nanoparticles (AgNPs) formulation of the experimental ferns confirmed the synthesis of nanoparticles (433.50nm, 450.00nm and 444.00 nm for C. interruptus, C. dentata and N. cordifolia, respectively). The pesticidal property of the crude extracts and ferns-AgNP (Fe-AgNP) were evaluated in the laboratory on Spodoptera litura (Fab.)(Lepidoptera: Noctuidae) third instar larvae. The crude extract and Fe-AgNP formulations exerted their influence on the developmental period, pupation rate, pupal weight and adult emergence which were reduced significantly. They also caused larval, pupal and adult deformities that confirm the insecticidal activity of the plant.
