ABSTRACT
The concentration of potato(Solanum tuberosum L.) glycoalkaloids(PCA) (i.e.,-chaconine and -solanine) in Korean cultivated potato plant, and in the different varieties, parts and weights of the potato tubers, were determined by high-performance liquid chromatography(HPLC). The highest concentrations of PGA in potato plants were found in the roots, followed by the stems and leaves. A large quantity of PGA existed in the periderm of 'Atlantic' potatoes, whereas 'Irish Cobbler' contained the lowest amount in five cultivated potato tubers.'Irish Cobbler' potatoes were divided into three parts and the PGA content in each part was determined. It was found that both of the end parts of the potatoes contained higher PGA than the middle part. The PGA contents in four different sizes of potatoes increased toward the smaller size. Thesignificantly high level of PGA was contained in the smallest size potato tubers, which have been used widely for Korean cooking.
