Abstract

Nine cycloartane-type glycosides were isolated from three species of the genus Astragalus (Fabaceae): From the aerial parts of A. cicer L., two new saponins, cicerosides A and B (1 and 2, resp.), i.e., a tetradesmosidic and tridesmosidic cycloartane-type glycosides besides one known compound, from the roots of A. sempervirens LAM., one known saponin, and from the roots of A. ptilodes Boiss. var. cariensis BOISS., five known compounds. Their structures were established mainly by 600-MHz 2D-NMR techniques (1H, 1H-COSY, TOCSY, NOESY, HSQC, and HMBC) and mass spectroscopy.
