In order to answer the question, which is the essential component of Perilla-anthocyanin, 'perillanin' or 'shisonin', leaf extracts from two common varieties of the plant were subjected to paper chromatographic study. The results have shown that the anthocyanin is nothing other than 'shisonin', i.e. p-hydroxycinnamic acid derivative of 3 : 5-o-diglucosidylcyanidin, as described by Kuroda and Wada. There was found no evidence in favor of the presence of Kondo's 'perillanin'.
