HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHIC SEPARATION OF POTATO GLYCOALKALOIDS

Separations of three glycoalkaloids (a-chaconine, β-chaconine, and a-solanine) have been achieved by using three different columns: μBondapak C18, μBondapak NH2, and a carbohydrate analysis column. These methods have been employed to examine the purity of the potato glycoalkaloids isolated by thin-layer and column chromatographic separations. Also, samples of tubers, peels, blossoms, and sprouts have been analyzed to determine their content of a-chaconine, β-chaconine, and a-solanine by using the carbohydrate and μBondapak NH2 columns. © 1979.
