An HPLC method for assaying 25(OH)D3 in extracts of human serum is described. The method involves extraction of serum with methanol-dichloromethane and chromatography on a column of Sephadex LH-20 prior to HPLC with quantitation by UV absorbance. Comparison with a CBP assay for 25(OH)D3 showed no difference between the two methods.
描述了一种用于测定人血清提取物中25(OH)D3的高效液相色谱法。该方法包括用甲醇 - 二氯甲烷提取血清，并在高效液相色谱分析前在Sephadex LH - 20柱上进行色谱分离，通过紫外吸光度进行定量。与25(OH)D3的CBP测定法比较表明，两种方法之间没有差异。
