- 摘要:
- 根据检测不同高氯酸浓度和水解温度对大豆种子的水解效果,检测不同流动相对鸟嘌呤、腺嘌呤、次黄嘌呤、黄嘌呤4 种成分的分离效果,建立了稳定准确的大豆种子中多组分嘌呤含量的高效液相色谱分析方法。结果表明:在100℃条件下, 35% ( v /v) 的高氯酸处理60 min 时豆粉水解效果最佳; 使用Welch Ultimate Polar RP18 ( 4. 6 mm ×250 mm,5. 0 μm) 色谱柱以0. 02 mol·L - 1 磷酸二氢钾缓冲液( pH2. 9) 作为流动相时,4种嘌呤在0. 05 ~ 25 mg·L - 1浓度范围内均可完全分离且响应峰面积与浓度呈良好线性相关( r > 0. 999 9) ,相对标准偏差为2. 97% ~ 6. 25%,加标回收率为89. 19% ~ 110. 97%。
- Abstract:
- A stable and accurate HPLC ( high performance liquid chromatography) procedure for measuring multiple componentsof purines in soybean seeds was established based on choosing an appropriate HClO4 content and temperature for hydrolysisof mashed soybean specimen and choosing an appropriate buffer solution mobile phase. The optimized hydrolysis conditionwas hydrolyzing mashed soybean seed with 35% ( v /v) of HClO4 for 60 min at 100℃. The optimized chromatography conditionwas using Welch Ultimate Polar RP18 ( 4. 6 mm × 250 mm,5. 0 μm) as chromatographic column with 0. 02 mol·L - 1KH2 PO4buffer solution ( pH2. 9) as mobile phase at flow rate of 1. 0 mL·min - 1. Under this system,the ademine,guanine,hypoxanthineand xanthine within 0. 05 - 25 mg·L - 1 could be fully separated and the response peak area was linearly correlated withpurine content perfectly ( r > 0. 999 9) with the range of relative standard deviation ( RSD or CV) as 2. 97% - 6. 25% and therange of spiked recovery rate as 89. 19% - 110. 97%.
