ABSTRACT

A new cycloartane methysteroid cyclopycnanthogenin, has been found in stems of the plantAstragalus pycnanthus Boriss. (Leguminosae). Its structure has been determined on the basis of IR, mass, and1H and13C NMR spectra with the involvement of DEPT experiments and 2M1H−1H and1H−13C chemical shift correlations [1H−1H COSY and1H−13C (HMQC)] and also 2M NMR correlations of long-range1H−13C interactions (HMBC). Cyclopycnanthogenin is 6α, 16β, 25-trihydroxy-20R, 24S-epoxycycloartane-3-one. More... »
