摘要:

目的:建立测定莲子壳提取物中原花青素含量的高效液相色谱法。方法:色谱柱Diamonsil C18柱(4.6 mm×250 mm,5 μm);流动相甲醇-水-甲酸-异丙醇(13∶73∶8∶6,V/V);检测波长525 nm;流速1.0 mL/min;柱温35 ℃;进样量10 μL。结果:原花青素在37.6~300.8 μg/mL与峰面积呈良好的线性关系,r=0.999 5,加样回收率为99.2%,相对标准偏差为0.30%。结论:该方法简便、快速、准确,具有良好的重复性和回收率,可作为莲子壳提取物中原花青素含量的测定方法。

Abstract:

Objective: To establish a high performance liquid chromatography (HPLC) method for the determination of
proanthocyanidins in lotus seed shell extract. Methods: HPLC analysis was carried out using Diamonsil C18 (4.6 mm × 250 mm,
5 μm), and the mobile phase consisted of methanol-water-formic acid-isopropyl alcohol (13:73:8:6, V/V) at a flow rate of
1.0 mL/min. The detection wavelength was set at 525 nm, the column temperature was set at 35 ℃, and the injection volume
was 10 μL. Results: A good linearity of proanthocyanidins was achieved in the range of 37.6–300.8 μg/mL (r = 0.999 5).
The average recovery was 99.2%, with relative standard deviation (RSD) of 0.30%. Conclusion: This method is simple,
reproducible, accurate and reliable and thus can be used for quality control of lotus see shell extract.

Key words: lotus seed shell extract, proanthocyandins, high performance liquid chromatography (HPLC)
