摘要
［目的］ 为了寻找适合于标准植酸的测定及微量测定的方法。［方法］ 采用可见分光光度法, 测定植酸的含量。［结果］ 在标准曲线下，植酸浓度在0~32 μg/ml范围内与吸光度呈良好线性关系，方程为：Y=-2.284 2X＋0.384 1（R=0.997 3），平均回收率为97.35%，RSD为4.82%（n=4）。［结论］该方法操作简便、快速、准确，可作为植酸的定量分析方法。
[ 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.
