Abstract: This study aimed to establish a Camptotheca acuminata hydroponic system and confirm the possibility of extracting camptothecin through root exudates. The study was based on Camptotheca acuminata through picking acuminata seedlings and under soilless hydroponic. Camptothecin, hydroxycamptothecin and other root exudate were analyzed by high-performance liquid chromatography (HPLC) and gas chromatographmassspectrometer-computer (GC-MC). The result showed that Camptotheca acuminata root exudates presented in a certain content of camptothecin and hydroxycamptothecin, and allelochemicals such as dibutyl phthalate.
