[Study on the sorption and isolation of shikimic acid by 717 anion exchange resin].

OBJECTIVE: To establish a convenient, practical and environmental method for extracting and isolating shikimic acid. METHODS: The content of shikimic acid was measured by RP-ion-pair HPLC, the effects of different pH, temperature, sample concentration and eluate concentration on 717 anion exchange resin were studied. RESULTS: The yield of shikimic acid was 96.52% on the condition of 22 degrees C, pH > 6.5, 7.5 mg /ml sample concentration and 0.03 mol/L HCl eluting. CONCLUSION: This method is feasible and suitable for the extraction and isolation of shikimic acid.
