title: Anthocyanin compositions in sweetpotato (Ipomoea batatas L.) leaves.
abstract: The anthocyanin composition of three varieties, Simon No. 1, Kyushu No. 119, and Elegant Summer, in sweetpotato (Ipomoea batatas L.) leaves was examined for promoting new uses. Fifteen anthocyanin compounds were identified and measured. HPLC clearly showed quantitative differences, but not qualitative ones. The anthocyanins were acylated cyanidin and peonidin type. The result suggests that the major anthocyanin composition of sweetpotato leaves is cyanidin type.
