Abstract

Six anthocyanins were isolated from the brownish-red flowers of Ipomoea purpurea. Cyanidin 3-sophoroside was identified as the parent anthocyanin. The other five anthocyanins are acylated derivatives with glucosylcaffeic acid and/or caffeic acid. The structures of three were unambiguously determined to be cyanidin )-beta-D-glucospyranosyl)-beta-D-glucopyranoside], cyanidin yl)-6-O-(trans-caffeoyl)-beta-D-glucospyranoside]. The remaining two pigments could not be determined because of their small yields. In these flowers, the major pigments are cyanidin 3-glucosylcaffeoylglucosylcaffeoyl-sophoroside, cyanidin 3-sophorosideand cyanidin 3-caffeoylsophoroside. They are considered to play an important role in producing the dusky colour of these petals. (C) 1998 Elsevier Science Ltd. All rights reserved.
