Isolation and identification of alkaloids from fruits of Berberis thunbergii DC
نویسندگان
چکیده
Two major bisbenzylisoquinoline alkaloids, isotetrandrine and berbamine and three protoberberine type alkaloids berberine, palmatine, and jatrorrhizine were isolated from seeds of Berberis thunbergii DC. 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 (i.r., u.V., and mass spectrometry), optical rotation, and comparison with specimens.
