Determination of escin based on its inhibitory action on lactose crystallization

Publication Date
  • Pharmacology


A sensitive and simple kinetic turbidimetric method for the determination of escin, based on its inhibitory action on the crystallization of lactose, is presented. Supersaturated solutions of lactose were prepared by addition of acetone to a stable aqueous lactose solution. The induction period of the crystallization process was measured turbidimetrically in the absence and presence of escin. The method was applied to the determination of escin in pharmaceutical products.
