    • PROBLEM TO BE SOLVED: To provide a method for raising a camptothecin-producing plant with a high ingredient content such as camptothecin, vigorously growing and easily cultivated with high productivity, and a method for producing the camptothecin and its analogs using the plant.
      SOLUTION: The method for raising the camptothecin-producing plant is characterized by artificially mating Ophiorrhiza pumila with Ophiorrhiza kuroiwai. The method for producing the camptothecin and/or its analogs is characterized by propagating and cultivating the resultant hybrid plant obtained by the artificial mating and extracting the camptothecin and/or its analogs from the grown plant. Furthermore, the method for producing the camptothecin and/or its analogs is characterized by aseptically culturing the hybrid plant obtained by the artificial mating and extracting the camptothecin and/or its analogs from the cultured cell thereof.
