국가 공정서 중 하나인 대한민국약전외의약품 기준에는 디페메린염산염의 정량법으로 유해시약인 아세트산수은을 사용하는 비수적정법이 수재되어 있다. 본 연구에서는 디페메린염산염의 환경 친화적인 대체 시험법으로 보다 안전하고 효율적인 친환경용매인 에탄올을 사용하는 중화적정법을 개발하고,분석법을 검증하였다. 디페메린염산염의 직선성은 상관계수(r)가 0.999 이상을 나타내었고, 정확도는99.10~99.71%, 정밀도는 0.64% 이하로 나타났다. 개발된 시험법은 대한민국약전외의약품 기준의 개정에기여가 될 것이다.
Currently nonaqueous titration method for the assay method using the hazardous reagent, mercuryacetate for difemerine hydrochloride has been used in Korean Pharmaceutical Codex. We developed analternative titration assay method by substituting the use of the hazardous reagent, mercury acetate to the useof less toxic ones like ethyl alcohol. The linearity of the calibration curves in the desired concentration rangewas good (r>0.999). Precision was less than 0.64%. Accuracy was obtained with recoveries in range of 99.10%and 99.71%. The developed assay could be expected to become valuable tools for revising the KoreanPharmaceutical Codex.
