A simple, rapid and inexpensive fluorimetric method for simultaneously determining ASA and SA in a single scan of the co-existing specimen had been established. When the wavelength interval (delta lambda) is 80 nm for scaning, the amounts of ASA and AS could be quantitatively determined respectively. The fluorescence intensity was linearly related to the aspirin concentration in the range of 4.0 x 10(-6)-1.0 x 10(-4) mol x L(-1) with correlation coefficient 0.9949; the fluorescence intensity was linearly related to the salicyclic acid concentration in the range of 8.0 x 10(-7)-1.0 x 10(-4) mol x L(-1) with correlation coefficient 0.9975, the determination limit was 4.0 x 10(-7) mol x L(-1). The method is simple, rapid and inexpensive, it can be used for medicament analysis.

UI	MeSH Term	Description	Entries
D001241	Aspirin	The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis.

D012459	Salicylates	The salts or esters of salicylic acids, or salicylate esters of an organic acid. Some of these have analgesic, antipyretic, and anti-inflammatory activities by inhibiting prostaglandin synthesis.	Salicylate,Salicylic Acids,Acids, Salicylic
D013050	Spectrometry, Fluorescence	Measurement of the intensity and quality of fluorescence.	Fluorescence Spectrophotometry,Fluorescence Spectroscopy,Spectrofluorometry,Fluorescence Spectrometry,Spectrophotometry, Fluorescence,Spectroscopy, Fluorescence
D015203	Reproducibility of Results	The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
