ABSTRACT
An improved microfluorimetric method for determination of serum vitamin A was presented. In this method, the excitation wavelength 345nm and emission maximum 480nm were selected, and cyclohexane as solvent for extraction of saponified vitamin A in the serum samples to be tested was used. The sensitivity was sufficient for measurement of vitamin A content in 20*l serum taken from normal fasting blood without elimination of interference. The recovery averaged 99.0% (93.0-105.5).When this method was applied to laboratory study or field work, practically, the results showed that the values of vitamin A obtained seemed to correlate with its nutritional status of experimental animals or subjects investigated. The procedure was simple, reproducible and easily acceptable, espicially in the field work.
