Palmatine is a protoberberine alkaloid found in several plants including Coptis chinensis (Rhizoma coptidis, chinese goldthread), Corydalis yanhusuo, Tinospora cordifolia (gurjo, heart-leaved moonseed), Tinospora sagittata, Phellodendron amurense (amur cork tree), and Stephania yunnanensis.

It is the major component of the protoberberine extract from Enantia chlorantha.

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