A new C21-steroidal glycoside from Cynanchum stauntonii
摘要:
A new C21-steroidal glycoside with two known compounds were isolated from the root of Cynanchum Stauntonii. Based on the spectral analysis, including MS, 1H NMR, 13C NMR, DEPT, 1H-1H COSY, 13C-1H COSY, HMQC and HMBC, their chemical structures were determinated as glaucogenin-C 3-O-α-L-cymaropyranosyl-(1→4)-β-D-digitoxopyranosyl-(1→4)-β-D-canaro-pyranoside (1), stigmasterol (2) and ursolic acid (3).
