| Abstract: | Objective] The research aimed to find the method suited to the measurement of standard phytic acid and microdetermination. Method] A method for determination of phytic acid by speetrophotometry was studied. Result] The regression equation within the range of＇ the standard sample concentration in 0 -32 μg/ml was Y = -2. 284 2X ＋ 0. 384 1 with a good linearity （R = 0. 997 3 ）. The average recovery rate was 97.35 % and RSD was 4.82% （n = 4）. Conclusion] The method was simple, rapid, accurate and suitable for the quality evaluation of phytic acid. |
