STEROLS, STEROIDAL SAPOGENIN AND STEROIDAL ALKALOID IN CALLUS-CULTURE OF SOLANUM, LACINIATUM AIT

Aiming to get useful steroidal alkaloids by tissue culture of Solanum laciniatum Ait., indefinitely growing callus tissue was prepared from the mother plant. Some nutritional requirements for the growth of the callus tissue were studied. By examining steroidal compounds in callus culture, cholesterol, stigmasterol, P-sitosterol, lanosterol, squalene, diosgenin and a new steroidal alkaloid were found to be formed in the callus culture. The new steroidal alkaloid was found to be solasodine derivative containing rhamnose and other unidentified sugars. © 1979 Taylor & Francis Group, LLC.
