Abstract

Four kinds of delphinidin glycoside were found in the bluish-purple flowers ofVinca major. Among them, two glycosides were isolated in a crystalline state by application of Sephadex and Avicel columns. The names of vincanin A and vincanin B were tentatively assigned to those new glycosides. They were respectively identified as delphinidin 3-robinobiosido-5-rhamnoside and delphinidin 3-robinobioside on the basis of chemical, spectral and paper chromatographic analyses. The identity of two other glycosides could not be fully confirmed because of the smallness of the amount.
