摘要：
The known compound oleanolic acid (1) and anew cycloartane glycoside cyclounifolioside A (2), which has the structure 6,16-di-O-acetyl-24R-cycloartan-3beta,6alpha,16beta,24,25-pentaol 3-O-beta-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).
