Two new C-21 steroidal glycoside epimers, paniculatumosides A and B (1 and 2), based on a 13,14:14,15-disecopregnane-type skeleton, with neocynapanogenin B (3) and neocynapanogenin C (4) as two new aglycons, were isolated from the roots of Cynanchum paniculatum. Their structures were determined by spectral data interpretation.
从徐长卿的根部分离得到了两个新的C-21甾体糖苷差向异构体，徐长卿苷A和B（1和2），其基于13,14:14,15-二裂孕甾烷型骨架，同时得到了两个新的苷元，新白前苷元B（3）和新白前苷元C（4）。通过光谱数据解析确定了它们的结构。
