抄録

Two new flavonoid compounds, named sophoraisoflavanone A (I), mp 178-180°, C₂₁H₂₂O₆, and sophoraflavanone B (II), mp 193-195°, C₂₀H₂₀O₅, together with sophoronol (IV), isosophoranone (V) and isobavachin (VI) were isolated from the aerial parts of Sophora tomentosa L. Besides them, a new phenolic compound (III), mp 108-110°, C₂₇H₄₄O₄, was also isolated. The structures of them were determined by chemical and spectroscopic studies. Sophoraisoflavanone A (I) exhibited antifungal activity.
