Investigation of the weak-base fractions of two species, B. microphylla Sieb. et Zucc. var. suffruticosa Makino and B. microphylla Sieb. et Zucc. var. suffruticosa Makino forma major Makino, has led to the isolation of ten new alkaloids. In addition, another new alkaloid was isolated from the strong-base fraction of the latter species. These alkaloids are structurally closely related, and their interconversion
