Abstract: Two major bisbenzylisoquinoline alkaloids, isotetrandrine and berbamine, and 3 protoberberine type alkaloids, berberine, palmatine, and jatrorrhizine, were isolated from seeds of B. thunbergii. Berberine and oxyberberine, which is not present in the seeds, were isolated from the pericarp. Identity of the isolated substances was verified by spectral means (IR, UV, and mass spectrometry), optical rotation, and comparison with specimens.
