Abstract: The optimal conditions of extraction of Camptothecin by NaOH aq. from fruits of Camptotheca acuminata using orthogonal experimental design were studied. The optimal conditions are as follows: the concentration of NaOH aq. is 0.3%, the extracted time is 3~4 hours, the volume of extracted solvent is 16ml/g raw material·time, and the extracted temperature is room temperature.

Key words: Camptothecin, Extraction, fruits of Camptotheca acuminata
