The glycoalkaloids content in the tubers of 7 potato varieties grown in Oman was determined by HPLC in both the peel and the flesh. Tubers from these potato varieties were analyzed for their rates of glycoalkaloids accumulation in response to stresses caused by storage under fluorescent light. Exposure to fluorescent light (15.72 mumol m-2 s-1 photosynthetically active radiation) was found to result in an increase in the glycoalkaloids concentration within tuber tissue this increase in the total glycoalkaloids content was associated with a decrease in the alpha-chaconine: alpha-solanine ratio indicating a more active synthesis of alpha-solanine and a less active synthesis of alpha-chaconine.
