目的：测定复方降压片中６种组分的含量，为该药提供质量控制方法。方法：应用褶合曲线分析法，结合计算机信息处理技术，同时分别测定了复方降压片中６种组分的含量。结果：维生素Ｂ６、维生素Ｂ１、氯氮、盐酸异丙嗪、硫酸双肼肽嗪、氢氯噻嗪的样品平均回收率和ＲＳＤ分别为９９．２３％，０．１６％；１００．４５％，０．１９％；９９．４９％，０．４３％；１００．４４％，０．１８％；９９．２９％，０．０９％；９９．２３％，０．４１％。结论：采用计算机辅助褶合曲线法，不经分离直接对其同时分别定量获得成功，可作为该药物一种可取的质量控制方法。
Objective: To determine the content of six components in compound antihypertensive tablets and to provide quality control method for the drug. Methods: Convolution curve analysis method and computer information processing technique were used to determine the content of six components in compound antihypertensive tablets. Results: The average recoveries and RSDs of vitamin B6, vitamin B1, chlordiazepoxide, promethazine hydrochloride, bilazine sulfate and hydrochlorothiazide were 99.23%, 0.16% and 100.45%, respectively. 19%; 99.49%, 0.43%; 100.44%, 0.18%; 99.29%, 0.09%; 99.23%, 0.41%. CONCLUSION: The computer-assisted convolution curve method can be used as a preferable quality control method for the success of quantitative determination of the drug simultaneously without separation.
