The structures of two new cycloartane triterpenoids, cycloalpigenin A and cycloalpioside A, isolated from Astragalus alopecurus Pall. (Leguminosae) have been established on the basis of chemical transformations together with1H,13C, and 2D1H-1H and1H-13C chemical shift correlation NMR spectroscopy and IR, mass, and CD spectra. Cycloalpigenin A is 3β,16β,25… CONTINUE READING
