| Abstract: | The known compound oleanolic acid (1) and a new cycloartane glycoside cyclounifolioside A (2), which has the structure 6,16-di-O-acetyl-24R-cycloartan- 6 ,16,24,25-pentaol 3-O--D-glucopyranoside, were isolated from Astragalus unifoliolatus Bunge. The structures of the isolated compounds were established using chemical transformations and two-dimensional spectra (TOCSY, ROESY, HMBC, HSQC, COSY). |
| Keywords: | Astragalus unifoliolatus triterpene glycoside cycloartane 6-16-di-O-acetyl-24R-cycloartan-3 |
