Compounds of general Formula I in which the substituents of R1-R7 are hydrogen, hydroxy group, C1-6 alkyl group, C1-6 alkoxy group, or epoxypropoxy, but at the most, six of the substituents can simultaneously be hydrogen, methoxy group, or hydroxy group, or epoxypropoxy group for activity against hepatoma. There are also described processes for the preparation of the novel compounds and useful intermediates. Substitute benzophenones are described.
