摘要: 目的:建立黑豆皮中矢车菊素-3-O-葡萄糖苷的含量测定方法,测定5个不同产地黑豆皮中矢车菊素-3-O-葡萄糖苷的含量。方法:采用HPLC法测定黑豆皮中矢车菊素-3-O-葡萄糖苷的含量,色谱柱采用Phenomenex Luna Su C18 柱 (250mm×4.60mm,5μm);流动相A相为0.5%磷酸溶液,B相为水-乙腈(50:50),进行梯度洗脱;流速0.8mL/min;检测波长520nm;柱温30℃;进样量10μL。结果:矢车菊素-3-O-葡萄糖苷标准曲线回归方程为:Y=2×107X-33120(r=0.9998),在 0.1041~1.041μg范围内线性关系良好,平均回收率分别为92.4%、 92.5%和95.5%,不同产地黑豆皮中矢车菊素-3-O-葡萄糖苷含量范围为5.263~12.829mg/g。结论:所用方法简便、准确,可用于不同产地黑豆皮的质量控制。

Abstract: Objective: To determine cyanidin-3-O-glucoside (C3G) content in black soybean hulls grown in different regions of China by HPLC. Methods: The chromatographic separation was performed on Phenomenex Luna Su C18 (250 mm × 4.60 mm, 5 μm) column by gradient elution using 0.5% phosphoric acid solution as mobile phase A and water: acetonitrile (50:50, V/V) as mobile phase B at a flow rate of 0.8 mL/min. The column temperature was set at 30 ℃and the detection wavelength at 520 nm. Results: The developed regression equation of cyanidin-3-O-glucoside standard is: Y = 2 × 107X - 33120 (r= 0.9998). A good linearity was shown in the range of 0.1041-1.041 μg. The average recoveries at three spike levels were 92.4%, 92.5% and 95.5%, respectively. The contents of cyanidin-3-O-glucoside in samples from Northeast China and Shandong, Hubei and Anhui provinces were in the range of 5.263-12.829 mg/g. Conclusions: The method is simple and reliable, and may be used for the quality control of black soybean hull from different geographic origins.
