Biological Activity of Diterpenoids and Biflavonoids

In addition to coumarinolignans (cleomiscosin A 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.
