Abstract
From bulbs of Allium ampeloprasum L. (elephant garlic: Liliaceae), a new spirostane-type saponin, named ampeloside Bs1 (7), and two new furostane-type saponins, named ampelosides-Bf1 (8) and -Bf2 (9), were isolated along with a known spirostane-type saponin, the prosapogenin of aginoside (1). The structures of the new saponins (7-9) were established as agigenin 3-O-.beta.-glucopyranosyl(1 .fwdarw. 3)-.beta.-glucopyranosyl(1 .fwdarw. 4)-.beta.-galactopyranoside, (25R)-26-O-.beta.-glucopyranosyl-22-hydroxy-5.alpha.-furostane-2.alpha.,3.beta.,6.beta.,26-tetraol-3-O-.beta.-glucopyranosyl(1 .fwdarw. 3)-.beta.-glucopyranosyl(1 .fwdarw. 4)-.beta.-galactopyranoside and (25R)-26-O-.beta.-glucopyranosyl-22-hydroxy-5.alpha.-furostane-2.alpha.,3.beta.,6.beta.,26-tetraol-3-O-.beta.-glucopyranosyl(1 .fwdarw. 4)-.beta.-galactopyranoside, respectively. Antifungal activity of these saponins (1, 7 and 8) is discussed.This publication has 1 reference indexed in Scilit:
