GAO, Hua et al. Paniculatumoside G, a new C21 steroidal glycoside from Cynanchum paniculatum. Rev. bras. farmacogn. [online]. 2017, vol.27, n.1, pp.54-58. ISSN 0102-695X.

A new C21 steroidal glycoside, paniculatumoside G, together with neocynapanogenin C isolated for the first time from the natural source and two known compounds were isolated and characterized from the roots and rhizomes of Cynanchum paniculatum (Bunge) Kitag. ex H.Hara, Apocynaceae, a commonly used Traditional Chinese Medicine. On the basis of spectroscopic analysis, including HR-ESI-MS, 1D and 2D NMR spectral data, the structure of the new C21 steroidal glycoside was elucidated as neocynapanogenin H 3-O-β-D-oleandropyranoside.

Keywords : Asclepiadaceae; Cynanchum paniculatum; C21 steroidal glycoside; Neocynapanogenin H 3-O-β-D-oleandropyranoside.
