The new flavone glycosides tanoside I and II in addition to three known flavonoids and daucosterol were isolated from the Georgian endemic species Astragalus tanae Sosn. Their structures were elucidated as chrysoeriol-7-O-β-D-glucopyranosyl-4′ -O-α-L-rhamnopyranoside, chrysoeriol-4′ -O-α-Lrhamnopyranoside, kaempferol-3-O-β-D-glucopyranosyl(2→1)-O-α-L-rhamnopyranoside (kaempferol-3-O-β-D-neohesperidoside), tamarixin, apigenin, and β-sitosterol-3-O-β-D-glucopyranoside (daucosterol).
除了三种已知的类黄酮和胡萝卜苷外,还从格鲁吉亚特有物种黄芪中分离出新的黄酮苷 tanoside I 和 II。其结构被阐明为 chrysoeriol-7-O-β-D-glucopyranosyl-4′ -O-α-L-rhamnopyranoside、chrysoeriol-4′ -O-α-Lrhamnopyranoside、kaempferol-3-O-β-D-glucopyranosyl (2→1)-O-α-L-吡喃鼠李糖苷(山奈酚-3-O-β-D-新橙皮苷)、柽柳素、芹菜素和 β-谷甾醇-3-O-β-D-吡喃葡萄糖苷(胡萝卜苷)。
