The production of the steroidal alkaloid solasodine, an alternative to diosgenin as a precursor for the commercial production of steroid drugs, was studied in hairy root, callus, and cell suspension cultures of Solanum aviculare Forst. through manipulation of culture medium. The individual and combined effects of medium components on the growth index and the production of solasodine were analyzed using factorial analysis of variance. Solasodine content was optimized to 6.2 mg g-1 in the hairy root, 1.4 mg g-1 callus, and 0.7 mg g-1 in cell suspension cultures (dry weight). An improved isocratic reversed phase high performance liquid chromatographic method provided selective determination of the solasodine content of these samples. Analysis of growth and solasodine content of hairy root cultures and callus cultures demonstrated that the production of solasodine was shown to be growth-dependent in hairy root cultures but not in callus cultures.
