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.
