Abstract: 7-hydroxyl group of flavonols; for the present, it is suggested that a separate enzyme is required for catalysing this step in the synthesis.SUMMARY 1. Nine flavonol glycosides have been found in potato flowers.They are the 3-glucosides, 3rhamnosylglucosides, 3-diglucosides and 3-gluc- osylrhamnosylglucosides ofkampferol and quercetin and the 3-rhamnosylglucoside of myricetin.2. Kampferol 3-diglucoside 7-rhamnoside and kampferol 3-triglucoside 7-rhamnoside have been found in potato seeds.3. Luteolin 7-glucoside has been found specifically in the flowers of a wild species, Solanum 8toloniferrum.The distribution of the flavonol glyc- osides in wild and cultivated potato species is recorded.4. A gene controlling the transfer of glucose to quercetin 3-rhamnosylglucoside has been found.5. A scheme is proposed outlining the pathway of biosynthesis of the flavonol glycosides and an- thocyanins of the potato.The author is grateful to Dr G. J. Paxman for valuable discussions and help with the genetic aspects of this work.
