Rapid Micro-Assay of Camptothecin in Camptotheca acuminata Academic Article uri icon


  • A micro-assay has been developed to extract and rapidly quantify the anticancer alkaloid, camptothecin (CPT), from two leaf disks of Camptotheca acuminata Decaisne (Nyssaceae). This assay utilizes thin-layer chromatography in conjunction with fluorescence imaging to obtain reproducible measurements in the nanogram range. A large number of trees can be screened using this procedure to identify high producers of CPT in a relatively short period of time.
