Studies on the Constituents of Sophora Species. XVIII. Constituents of the Root of Sophora tomentosa L. (3)
A new chromone, named sophorachromone A (I), mp 138-139°C, C19H22O4, and a new flavanone, named sophoraflavanone A (II), mp 144-145°C, C25H28O5, were isolated together with isosophoranone (III) from the root of Sophora tomentosa L. (Leguminosae). The structures of I and II were established to be 8-g...

| description | A new chromone, named sophorachromone A (I), mp 138-139°C, C19H22O4, and a new flavanone, named sophoraflavanone A (II), mp 144-145°C, C25H28O5, were isolated together with isosophoranone (III) from the root of Sophora tomentosa L. (Leguminosae). The structures of I and II were established to be 8-geranyl-5, 7-dihydroxychromone and 6-geranyl-5, 7, 4'-trihydroxyflavanone, respectively, on the basis of chemical and spectral evidence. |
