EFFECT OF ETHEPHON AND SENIPHOS TREATMENTS ON THE ANTHOCYANIN COMPOSITION OF STARKING APPLES

摘要

Anthocyanins were extracted from the skin of apples (Malus domestica Borkh L. cv. Starking Delicious) with acidified methanol and were identified by HPLC. Cyanidin 3-galactoside was the most abundant anthocyanin. Other anthocyanins present in smaller amounts were cyanidin 3,5-diglucoside, cyanidin 3-glucoside, cyanidin 3-arabinoside, cyanidin 3-rutinoside, cyanidin 3-xyloside, cyanidin, and cyanidin 3-acetylglucoside. Treatment with ethephon and seniphos increased anthocyanin concentration and altered the percentage composition during ripening.
