The plant extracts must contain a critical minimum concentration of the phytovitamin D (measured in equivalents of 1,25-(OH).sub.2 D in order to induce cell differentiation. In the alternative, phytovitamin D, especially phytovitamin D glycoside, is employed in conjunction with a plant-derived glycosidase.
