Abstract: The method for determination of shikimic acid in the production of microbial fermentation was established. Using ultraviolet -visible spectrophotometry for determination of shikimic acid in the fermented liquid of shikimic acid producing bacteria. The detection wavelength was 245 nm,Linear equation of shikimic acid standard solution was A=3.084 4C-0.004 8(R2 =0.999 9). The recovery was 96.7% ~103.7% with average recovery of 100.04% ,RSD was 0.32% . The method is simple,fast,stable and accurate,and suitable to determine the shikimic acid in the production of microbial fermentation.
