Abstract
Four new 5α-steroidal glycosides with an unusual framework, funingenosides A (1), B (2), C (3), and D (4), were isolated from the roots of Parepigynum funingense. Their structures were elucidated on the basis of 1D and 2D NMR techniques. The structure and relative stereochemistry of compound 1 were demonstrated by X-ray crystallographic analysis.Keywords
