| 摘要 | PURPOSE: To accurately judge the presence of the effective component of a drug by direct visual observation, by judging the presence of the medicinal effect component by the display of the dye directly reacting with the volatile medicinal effect component to discolor. CONSTITUTION: The presence of a medicinal effect component is judged by the display of the dye directly reacting the volatile medicinal effective component to discolor and, when a drug is volatilized and the medicinal effect component is lost, the dye returns to the initial hue and the exhaustion of medicinal effect can be confirmed. That is, an oxidation inhibitor, an alkaline substance and the dye reversibly changing a color through the reaction with the volatile drug are allowed to coexist and, if necessary, an ultraviolet absorber is added to the base material. As the volatile drug, there is an org. phosphorus insecticide such as Acephate and, as the dye, there is a titration indicator such as alizarin red S. The alkaline substance is added to these substances to make the indicator acidic near to neutral before use. With respect to oxygen in air, a reducing agent such as monophenol is used as the oxidation inhibitor and, with respect to ultraviolet rays, an ultraviolet ray cutting filter is used or the ultraviolet absorber such as phenylsalicylate is used.
