Scutellarin is a flavone, a type of phenolic chemical compound. It can be found in the Asian "barbed skullcap" Scutellaria barbata and the north American plant S. lateriflora both of which have been used in traditional medicine. The compound is found only in trace amounts in the "Chinese skullcap" Scutellaria baicalensis, another plant used in traditional Chinese medicine. — Wikipedia
