Anti-proliferative and computational studies of two new pregnane glycosides from Desmidorchis flava.

Two new pregnane glycosides named desmiflavasides C (1) and D (2) were isolated from the sap of Desmidorchis flava (N.E.Br.

Nizwaside: a new anticancer pregnane glycoside from the sap of Desmidorchis flava.

The sap from the succulent Desmidorchis flava (N.E.Br) Meve and Liede yielded a new pregnane glycoside, named nizwaside whose structure was established using 1D and 2D NMR techniques as well as mass spectrometry (ESIMS).
