Abstract:
Objective To investigate the distribution of camptothecin(CPT),tryptophan synthase(TSB),and tryptophan decarboxylase(TDC) in Camptotheca acuminata seedlings.Methods The CPT content,TSB and TDC activities in different organs of C.acuminata seedlings subjected to different nitrogen forms treatments by sand culture in greenhouse were determined by HPLC.Results The CPT content in the young leaves of C.acuminata seedlings with different N-forms was significantly higher than that in other organs(P
