We report a spectrophotometric method for determining theophylline that is useful as a routine method for monitoring serum theophylline concentrations. The recovery of theophylline from serum is essentially 100% whem compared with aqueous standards taken through the entire procedure. Barbiturates, which interfere with most ultraviolet spectrometric methods for theophylline, do not interfere with this method. The procedure requires less than 45 min for completion and is more sensitive than most spectrophotometric methods for determining theophylline.
我们报告了一种用于测定茶碱的分光光度法,该方法可作为监测血清茶碱浓度的常规方法。与整个过程中使用的水标准品相比,从血清中回收茶碱的回收率基本为100%。干扰大多数紫外光谱法测定茶碱的巴比妥类药物,并不干扰该方法。该方法完成测定所需时间不到45分钟,并且比大多数分光光度法测定茶碱更灵敏。
