摘 要:建立了高效液相色谱法检测维生素C衍生物2-氧-α-D-吡喃葡萄糖基抗坏血酸的方法。采用Waters AtlantisT3-C18色谱柱;流动相为25 mmol/L的KH2PO4-H3PO4缓冲溶液(p H 2.0);流速为0.70 m L/min;柱温30℃;检测波长为238 nm。2-氧-α-D-吡喃葡萄糖基抗坏血酸质量浓度在0.0625~3 mg/m L范围内线性关系良好,相关系数〉0.99,回收率为100.2%,RSD为1.0%。A method was established for determination of 2-O-α-d-glucopyranosyl 1-ascorbic acid by highperformance liquid chromatography (HPLC). The analysis was performed on a Atlantis T3-C18 column(4. 6 × 150 mm, 5 μm ) using 0. 025 mol/L potassium dihydrogen phosphate and phosphoric acid buffer solution ( pH 2.0) as the mobile phase at a flow rate of 0. 70 mL/min and 30 ℃ and detected at 238 nm by PDA. The calibration curve of 2-O-α-d-glucopyranosyl 1-ascorbic acid was linear in the range of 0. 0625 - 3 mg/mL, with the correlation coefficient (r) larger than 0.99. The recovery was 100. 2% with the relative standard deviation (RSD) of 1.0%.
