摘要：

Both the steroidal glycoalkaloid mixture from potato (α-solanine and α-chaconine) and pure α-tomatine are able to complex with the sterols cholesterol, sitosterol, stigmasterol, campesterol and ergosterol in vitro. The sterol-complexing ability of tomatine was greater than that of the potato alkaloids and more akin to that of the steroidal saponin, digitonin. With all three compounds, cholesterol was the least-readily bound sterol while binding to other sterols was of a similar order. Complex formation with tomatine was not markedly influenced by temperature, and with the aglycone tomatidine did not appear to occur at all. © 1979.
