ペーパークロマト法によるマメ科植物の アントシアニン調査 1

Abstract

hree different anthocyanins are contained in the flower of cockspur coral tree (common coral tree) (Erythrina cristagalli L. var. compacta BULL.); namely two kinds of cyanidin glycoside in its petal and one kind of pelargonidin glycoside in its sepal. The present investigation showed that the former two were cyanidin 3- diglucoside and cyanidin 3-monoglucoside (chrysanthemin), and the latter was pelargonidin 3-monoglucoside (callistephin). It was also shown that the petal of other coral tree (E. corallodendron L.) contains two kinds of cyanidin glycoside, i. e. cyanidin 3-diglucoside and cyanidin 3-monoglucoside (chrysanthemin). The proportion of two cyanidin glycosides, that is, 3-monoglucoside vs. 3-diglucoside, was approx. 7:3 in the petal of cockspur coral tree, while approx. 1:9 in the petal of coral tree.Anthocyanin in the sepal was pelargonidin 3-monoglucoside in the case of cockspur coral tree, while it was composed of both cyanidin-3-monoglucoside and 3-diglucoside in coral tree flower. The proportion of these two cyanidin glucoside was approx. 9:1, that is quite reverse to the case of the petal.
