Studies on alkaloid constituents of Fritillaria yuminensis / 中国中药杂志

ABSTRACT

Twelve alkaloids were isolated from the bulbs of Fritillaria yuminensis by column chromatography over silica gel, ODS, and Sephadex LH-20, as well as RP-HPLC. Their structures were identified mainly by NMR and MS analyses as yubeinine(1), imperialine(2), delavinone(3), tortifoline(4), hupehenizioiside(5), imperialine-β-D-glucoside(6), kuroyurinidine(7), pengbeisine A(8), walujewine A(9), peimisine-3-O-β-D-glucopyranoside(10), solanidine-3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside(11), and solanidine-3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-β-D-glucopyranoside(12). Compounds 4-12 were obtained from F. yuminensis for the first time.
