摘要: 采用薄层层析色谱和制备高效液相色谱对罗汉果提取物组分A进行纯化,结果表明,硅胶薄层色谱法的最佳展开剂配比为正丁醇:冰醋酸:水=4:1:2;而制备高效液相色谱法的色谱条件为:ODS柱(φ20mm×250mm)、流动相30%甲醇溶液、流速8mL/min、检测波长210nm,按峰分步收集。经薄层色谱和高效液相色谱纯度鉴定,得到罗汉果提取物的三个组分A1、A2和A3。

Abstract: Component A was obtained from Fructus Momordicae extract by tandem AB-8/ADS-7 column chromatography followed by thin layer chromatography (TLC) using n-buttoanol-CH3COOH-water (4:1:2) as the development solvent. The component was separated into fractions A1, A2 and A3 by preparative high performance chromatography (HPLC) on ODS column (Ф 20 mm ×250 mm) using 30% aqueous methanol as the mobile phase at a flow rate of 8 mL/min, in which the detection wavelength was set as 210 nm. Fraction A2 was identified by HPLC as mogroside. Fractions A1 and A3 were unknown compounds.

Key words: Fructus Momordicae, mogroside, purification
