title: Cycloartane-Type Saponins from Astragalus tmoleus var. tmoleus.
abstract: Five known cycloartane-type glycosides were isolated from the roots of A. tmoleus Boiss. var. tmoleus. The identification of these compounds was mainly achieved by 1D and 2D NMR spectroscopic techniques and FABMS. The results of our studies confirm that triterpene saponins with the cycloartane-type skeleton might be chemotaxonomically significant for the genus Astragalus.
