Abstract
From the leaves of Viburnum cotinifolium, a new biflavonoid named as I-5, II-5, I-7, II-7, I-4’, II-4′-hexahydroxy [6-O-8] biflavone along with seven known flavonoids have been isolated. Their structures were elucidated from their chemical and physical data (IR, UV, 1H NMR, 13C NMR and mass spectra).
