摘要:

    建立应用高速逆流色谱分离纯化芍药中的芍药苷的方法。以正丁醇:乙酸乙酯:5% Na2SO4(4:1:5,V/V)为两相溶剂体系,在流速为2.0 mL/min、主机转速为800 r/min、检测波长为254 nm的条件下进行分离,从100 mg芍药粗提物中一次性分离制备得到56.13 mg芍药苷,高效液相色谱分析其纯度在98 %以上,通过质谱、核磁共振氢谱和核磁共振碳谱鉴定化合物的结构。该方法简便、快捷且重现性好,适合芍药苷的制备型分离。

Abstract:

      We established a method of separation and preparation of paeoniflorin from Paeonia lactiflora Pall. by highspeed counter current chromatography (HSCCC) with salt solution system. The separation was performed with butanolethyl acetate5%Na2SO4 (aq) (4:1:5,V/V) as a twophase solvent system, flow rate of 2.0 mL/min, rotation number of 800 r/min and detection wavelength of 254 nm. We obtained paeoniflorin of 56.13 mg from the crude extracts of 100 mg at one time. Its purity was more than 98%, which was determined by high performance liquid chromatography(HPLC). The structure of the target compound was identified by electrospray ionisation mass spectrometry (ESIMS),1Hnuclear magnetic resonance (1H-NMR) and 13C-nuclear magnetic resonance (13C-NMR). The method is simple and reproducible and suitable for separation and preparation of paeoniflorin.

Key words: Paeonia lactiflora Pall., HSCCC, Na2SO4 (aq), paeoniflorin
