Palmatine is a protoberberine alkaloid found in several plants including Phellodendron amurense, Rhizoma coptidis/Coptis Chinensis and Corydalis yanhusuo.^[1]

It is the major component of the protoberberine extract from Enantia chlorantha.^[2]

It has been studied for its potential use in the treatment of jaundice, dysentery, hypertension, inflammation, and liver-related diseases.^[3] This compound also has weak in vitro activity against flavivirus.^[4]
