Abstract

PURPOSE:To obtain a crude essence of plant having inhibitory action on topoisomerase and carcinostatic activity, by extracting Woodfordia fruticosa (L) Kurz with water or a polar organic solvent, concentrating or drying the extracted solution and properly repeating these operations. CONSTITUTION:Dried leaf part of Woodfordia fruticosa (L) Kurz is extracted with a low-boiling polar organic solvent such as methanol or ethanol under reflux. The prepared extracted solution is concentrated and dried to give a crude essence. Further to obtain a crude essence having higher activity, the concentrated solution or dried essence is extracted with water or a polar organic solvent except the solvent used first under a neutral or acid condition to give an extracted solution, which is concentrated or dried and optionally the similar operations are repeated to give a crude essence of plant.
