摘要

Six anthocyanins were isolated from the flowers of the Nagai line of Iris ensata Thunb. They were identified as petunidin and malvidin 3-O-β-[(4′′′-Z-p- coumaroyl-a-rhamnopyranosyl)-(1→6)-β-glucopyranoside]-5-O-β-glucopyranosides (1 and 3) and their E-forms (2 and 4), and petunidin and malvidin 3-O-rutinoside-5-O-glucosides (5 and 6). Though the E-form of petunidin 3-O-[(4′′′-p-coumaroylrhamnosyl)-(1→6)-glucoside]-5-O-glucoside has been reported, its Z-form was found for the first time. The presence of 2- and E-forms of malvidin 3-O-[(4′′′-p-coumaroylrhamnosyl)-(1→6)-glucoside]-5-O-glucoside is also reported for the first time. Fifty-one cultivars of Nagai line and their wild form (I. ensata var. spontanea) were divided into four anthocyanin patterns, i.e. l)the presence of 1-4,2) the presence of 2 and 4,3) the presence of 5 and 6, and 4) no anthocyanin.
