Agroastragaloside II, a new astragaloside was isolated from the hairy root culture of Astragalus membranaceus. Its structure was established as 3-O-beta-(2'-O-acetyl)-D-xylopyranosyl-6-O-beta-D-glucopyranosyl-(24S)- 3 beta,6 alpha,16 beta,24,25-pentahydroxy-9,19-cyclolanostane on the basis of spectroscopic data. Three known astragalosides, astragaloside II, isoastragaloside I and 3-O-beta-D-xylopyranosyl-cycloastragenol were also isolated.
农黄芪苷II是从黄芪毛状根培养物中分离得到的一种新的黄芪苷。基于光谱数据，其结构被确定为3-O-β-(2'-O-乙酰基)-D-吡喃木糖基-6-O-β-D-吡喃葡萄糖基-(24S)-3β,6α,16β,24,25-五羟基-9,19-环羊毛甾烷。还分离出了三种已知的黄芪苷，即黄芪苷II、异黄芪苷I和3-O-β-D-吡喃木糖基环黄芪醇。
