- Sophora arizonica, Sophora gypsophila, Sophora secundiflora, Sophora affinis, and Sophora japonica were recently reclassified as Dermatophyllum arizonicum, Dermatophyllum gypsophilum, Dermatophyllum secundiflorum, Styphnolobium affine, and Styphnolobium japonicum, respectively. Some legumes of the sub family Papilionoideae including Sophora species are reported to contain a variety of quinolizidine alkaloids. The quinolizidine alkaloid profiles of D. arizonicum, D. gypsophilum, D. secundiflorum, S. affine, and S. japonicum were investigated qualitatively and quantitatively using field collections and herbarium specimens throughout their range of geographical distribution for the native species. This is the first report of the alkaloid profiles of D. arizonicum and D. gypsophilum. Alkaloid profiles of the other species were compared to previous reports. The Dermatophyllum species contain quinolizidine alkaloids, and the teratogen anagyrine (11), while the Styphnolobium species do not contain quinolizidine alkaloids. The chemotaxonomic data are consistent with the reclassification of each species.
