N2 - Two biflavones isolated from Taxus cuspidata were identified with ginkgetin 1 and sciadopitysin 2 which belong to C3′‐C8 connected biflavones. The conformation of 2 in the solid state was determined by X‐ray analysis and the conformations of 1 and 2 in the liquid state were discussed using nmr techniques. Complete assignments of 1H and 13C nmr spectra about 1 were made on the basis of COSY, HMQC, HMBC and nOe experiments. Copyright © 1995 Journal of Heterocyclic Chemistry
