Abstract: Physic nut (Jatropha curcas L .) is a semi-fleshy small tree or large shrub , belonging to Euphorbiaceae family, Jatropha genus, which has highly tolerance to drought and nutrient deficiency . Their roots, barks, leaves and seeds can be used as medicines . The main components are fats, proteins and terpenes, and the toxins are curcin and seed oil in physic nut seed . Oil content of kernel is about 50% , which can be used as biological diesel oil without pollution . Curcin , seed oil and other extracts from physic nut seeds can be used as biological pesticide . There are a little study on development and dehydration behaviour of the seeds, and their regulation . Physic nut is an important strategic resource with great economic value .

Key words: Jatropha curcas,  , Biological diesel oil,  

摘要： 麻疯树(Jatropha curcas L .) 为大戟科(Euphorbiaceae) 麻疯树属半肉质小乔木或大灌
木, 具有很强的抗旱、耐贫瘠的特性。麻疯树的根、树皮、叶和种子均可入药。种子中主要
含有脂肪类物质、蛋白质和萜类物质, 其毒素为麻疯树毒蛋白和种子油。种仁中的含油量约
为50% , 可作为理想的生物柴油; 毒蛋白、种子油及其他种子提取物可作为生物农药。关
于麻疯树种子的发育、脱水行为及其调控研究较少。麻疯树是一种具有重要经济价值的战略
资源。
