摘要
本文探讨了用荧光光度法检测二氢奎尼丁的方法及实验条件，在０．０５ｍｏｌ／ＬＨ２ＳＯ４、１％ＨＡＣ介质中最大激发波长２５０ｎｍ、３６０ｎｍ，最大发射波长４４４ｎｍ，量子产率为０．５５（在０．０５ｍｏｌ／ＬＨ２ＳＯ４介质中）、０．５４（在１％ＨＡＣ介质中）。线性范围０·０５ｎｇ／ｍｌ～５．０μｇ／ｍｌ。检出限量为０．０１ｎｇ／ｍｌ。本方法简便、快速、灵敏度高，适用于临床医学监测服药病人血浆及尿液中药含量。
The method and experimental condition for the fluorimetric determination of dihydroquinidine were described. The maximum excitation wavelength at 250 and 360 urn and the maximum emission wavelength at 444nm were found in 1% HAC and 0.05mol/LH2SO4medium. The Linear range is 0. 05ng/ml--5. 0μg/ml with the detection limit of 0. 01ng/ml. The method is highly sensitive.
