摘要: 采用聚酰胺色谱结合高速逆流色谱法分离纯化了萹蓄中3种黄酮类化合物,建立了快速分离制备萹蓄中3种黄酮类化合物的方法。通过聚酰胺柱色谱富集黄酮类成分,再经过高速逆流色谱分离,以乙酸乙酯-甲醇-水-甲酸(体积比为4:1:5:0.1)组成的二相系统作为固定相与流动相,在主机转速为850 rpm,流速为2.0 mL/min,检测波长为254 nm的条件下制备样品。从150 mg富集黄酮成分的馏分中,一次性分离制备得到纯度为94.86%的杨梅树皮苷(myricitrin)7.5 mg,94.28%的黄芪苷(astragalin)13.8 mg,91.86%的合欢草素1(desmanthin-1)20.6 mg。所得馏分经高效液相色谱法(HPLC)检测纯度,并经MS和NMR鉴定化合物的结构。该方法简便、快速,所得产物纯度高,适合于黄酮类化合物的制备分离。

Abstract: In this study,three flavones were isolated and purified from Polygonum aviculare L.by polyamide chromatography combined with high-speed counter-current chromatography (HSCCC). A rapid and efficient method was established for preparative isolation and purification of three flavonoids from P.aviculare. The crude extract of P.aviculare was objected to polyamide chromatography to afford the flavones-enriching fraction.After that,the fraction was further separated by HSCCC with two phase solvent systems composed of ethyl acetate-methyl alcohol-water-formic acid (4:1:5:0.1,v/v).The lower phase as the mobile phase was operated at a flow rate of 2.0 mL/min,while the apparatus rotated at 850 rpm and the detection wavelength was 254 nm.As a result,7.5 mg of myricitrin,13.8 mg of astragalin,20.6 mg of desmanthin-1 were purified from 150 mg of the flavones-enriching fraction and each with 94.86%,94.28% and 91.86% purity as determined by HPLC.These compounds were identified by mass spectrometry (MS) and 1H-nuclear magnetic resonance (1H NMR).The method was simple,rapid and suitable for the preparative separation of flavonoids.
