摘要:

摘要:本文建立了简单且准确的测定1,3-二羟基丙酮(DHA)的高效液相色谱(HPLC)方法。以Alltima C18(5μm,250×4.6mm)为分离柱,5%甲醇水溶液(0.05%H3PO4调pH至3.0),流速为1mL/min,用紫外检测器在200nm处检测DHA。结果测得DHA标准样品的保留时间为6.2min,并测得DHA的线性范围为0.1~10.0 g/L。用HPLC法测得以甘油为底物发酵产DHA发酵液中DHA含量为6.2 g/L。并证明高效液相色谱法可有效应用于产DHA发酵过程中产物的检测。

Abstract:

A method to determine dihydroxyacetone (DHA) in fermentation broth was developed by high performance liquid chromatography (HPLC). DHA was separated on a Alltima C18(5μm,250×4.6mm). The mobile phase was 0.5% methanol solution (pH adjusted to 3.0 with H3PO4), the flow-rate was 1.0 mL/min and the detective wavelength was 200 nm. The detection limits of DHA was 0.1 g/L~10.0 g/L. 6.2 g/L DHA in the fermentation broth was detected by HPLC method, which was in agreement with the result by spectrophotometric method. The method in this paper was simple, rapid and applicable for DHA determination in the fermentation broth. The method was applicable for DHA determination in the fermentation process.
