摘要
摘要在野外，成草幼虫Costelytra zealandica (White)以蓖麻属植物(Ricinus communis L.)的叶片为食后很快死亡。对芦笋叶的化学成分进行了提取和分馏。利用草蛴螬成虫进行的生物测定证实，新鲜的红叶和部分化学成分是有毒的。质谱法鉴定主要有毒物质为生物碱蓖麻碱。
Toxicity of leaves from the castor oil plant, Ricinus communis L. (Euphorbiaceae), to adult grass grub, Costelytra zealandica (White) (Coleoptera: Scarabaeidae)
Abstract Adult grass grubs, Costelytra zealandica (White), die shortly after feeding on castor oil plant (Ricinus communis L.) leaves in the field. Chemical constituents of R. communis leaves were extracted and fractionated. A bioassay using grass grub adults confirmed that fresh R. communis leaves and some of the chemical fractions were toxic. The main toxic substance was identified by mass spectrometry as the alkaloid ricinine.
