Cardiac glycosides of Beaumontia brevituba and B. murtonii.
Cardiac glycosides from Beaumontia brevituba and B. murtonii were examined. Gentiobiosyl-beta-D-cymaroside and gentiobiosyl-alpha-L-cymaroside of digitoxigenin were isolated from the seeds, unripe fruits, and leaves of B. brevituba, and the leaves of B. murtonii. Oleandrigenin and/or delta 16-digitoxigenin glycosides having the same sugar moieties were not isolated from the leaves of B. brevituba but from the leaves of B. murtonii as well as the seeds of B. brevituba.
