In addition to coumarinolignans (cleomiscosin A and aquillochin) and 7,4'-dihydroxy-5-methoxyflavanone, a new dihydrochalcone, 2',4,4'-trihydroxy-6'-methoxydihydrochalcone, was isolated from the seeds of Coptis japonica var. dissecta.The structure of the dihydrochalcone was confirmed by comparison with relevant synthetic samples. - Key Word Index: Coptis japonica var. dissecta; Ranunculaceae; cleomiscosin A; aquillochin; 2',4,4'-trihydroxy-6'-methoxydihydrochalcone; 7,4'-dihydroxy-5-methoxyflavanone.
