Title: 5alpha-steroidal glycosides from Parepigynum funingense. Author: Hua Y, Liu HY, Ni W, Chen CX, Lu Y, Wang C, Zheng QT. Journal: J Nat Prod; 2003 Jun; 66(6):898-900. PubMed ID: 12828489. Abstract: Four new 5alpha-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.[Abstract] [Full Text] [Related] [New Search]
