摘要:

目的:通过半制备高压液相色谱分离技术,建立一种快速、稳定、高效制备高纯度罗汉果苷Ⅴ标准品的方法。方法:先采用树脂吸附脱色技术进行前处理,再通过半制备高压液相色谱分离制备罗汉果苷Ⅴ,色谱条件为Eclipse XDB-C18 色谱柱(9.4mm × 250mm,5μm) ,流动相为乙腈- 水,采用梯度洗脱,流速4mL/min,检测波长210nm,进样量36mg,柱温38℃。结果:分离得到的罗汉果苷Ⅴ的纯度为99.1%。结论:本方法具有操作简单、快速、稳定和产品纯度高等优点,可应用于实际样品的检测。

Abstract:

Objective: Semi-preparative HPLC was employed to establish a fast, stable and efficient method for preparation of high purity mogroside V. Methods: The crude mogroside V extract from the fruits of Siraitia grosvenorii was decolorized by D101 macroporous resin column chromatography before semi-preparative HPLC separation. Based on the use of Eclipse XDBC18 (9.4mm× 250 mm, 5μm) held at 38 ℃, the chromatographic conditions employed were as follows: mobile phase, a mixture of acetonitrile and water at a flow rate of 4 mL/min in the gradient elution mode, detection wavelength, 210 nm; abd sample load 36 mg. Results: The purity of the product obtained was as high as 99.1%. Conclusion: The developed method, thanks to the benefits of simplicity, rapidity, good stability and obtaining of high purity products, will have a good application prospect .
