Abstract
From the whole plants of Corydalis tashiroi MAKINO a new quaternary protoberberinium base dehydrodiscretamine chloride was isolated along with four known quaternary alkaloids by the application of droplet countercurrent chromatography (DCCC). The structure of the new base was established by spectral and chemical evidence. Eight known tertiary alkaloids were also isolated from the same plant.
