| 摘 要： | A new C21-steroidal glycoside with two known compounds were isolated from the root of Cynanchum Stauntonii.Based on thespectral analysis,including MS,1H NMR,13C NMR,DEPT,1H-1H COSY,13C-1H COSY,HMQC and HMBC,their chemicalstructures were determinated as glaucogenin-C 3-O-a-L-cymaropyranosyl-(1→4)-b-D-digitoxopyranosyl-(1→4)-β-D-canaropyranoside(1),stigmasterol(2)and ursolic acid(3).

| Abstract: | 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-canaropyranoside (1), stigmasterol (2) and ursolic acid (3). |
