The structures of three cycloartane glycosides isolated from Astragalus falcatus Lam. that were cyclogalegigenin derivatives were elucidated. Compound 1 was cyclogalegigenin-3-O-β-D-(3′-Oacetyl) xylopyranosyl-(2′→1′′ )′-O-α-L-rhamnopyranosyl-6-O-β-D-glucopyranoside (cyclofalcoside A); compound 2, cyclogalegigenin-3-O-β-D-(2′-O-acetyl)xylopyranosyl-6-O-β-D-glucopyranoside (cyclofalcoside B), which were new compounds. The structures of the isolated glycosides were elucidated using mass spectral and PMR and ¹³C NMR spectroscopic data.

来自乔治亚植物群黄芪的环阿烷糖苷

从黄芪中分离的三种环卡坦糖苷的结构。阐明了那些是环加脂素衍生物。化合物1为环galegigenin-3- O - β -D-(3'-Oacetyl)xylopyranosyl-(2'→1'')'- O - α -L-rhamnopyranosyl-6- O - β -D-吡喃葡萄糖苷(cyclofalcoside一种）; 化合物2 , cyclogalegigenin-3- O - β -D-(2'- O-乙酰基)xylopyranosyl-6- O - β-D-吡喃葡萄糖苷（cyclofalcoside B），它们是新化合物。使用质谱和 PMR 和¹³ C NMR 光谱数据阐明了分离的糖苷的结构。
