Enzymatic glycosylation of steroid alkaloids in potato tuber
The glycosylating activities of two enzymatic preparations from potato tubers were compared, using β-sitosterol and β-solanidine as substrate. The 25 000 g fraction synthesized steryl glucoside (SG) and acylsteryl glucoside (ASG) when β-sitosterol as well as β-solanidine was included in the reaction...

| Sumario: | The glycosylating activities of two enzymatic preparations from potato tubers were compared, using β-sitosterol and β-solanidine as substrate. The 25 000 g fraction synthesized steryl glucoside (SG) and acylsteryl glucoside (ASG) when β-sitosterol as well as β-solanidine was included in the reaction mixture. The AS fraction formed SG but not ASG from β-sitosterol and glycosylated β-solanidine forming six different derivatives. We tentatively related these products to the six components of solanine: α-, β- and γ-solanine and α-, β- and γ-chaconine. © 1977. |
