Abstract

The effect of light exposure on the steroidal glycoalkaloid content of Solanum phureja tubers has been investigated and compared with that in domesticated potato (Solanum tuberosum) tubers. The results indicated that the increase in the concentration of solanidine-based glycoalkaloids, ᾱ- solanine and ᾱ-chaconine was broadly similar in both species. However, in the S. phureja tubers, light exposure also induced the synthesis of tomatidenol-based glycoalkaloids. These have been identified as α- and β- solamarine. These glycoalkaloids were not detected in tubers continually stored in darkness. (C) 2000 Elsevier Science Ltd.
