摘要:

建立了亲水/反相二维制备液相色谱(Pre-2D-HILIC/RPLC)分离纯化络石藤中化学成分的分析方法。络石藤药材经醇提、活性炭脱色后用反相固相萃取柱除去色素和强极性物质,最终得到干燥的浅黄色粉末。一维亲水色谱选择Click XIon色谱柱(250 mm×20 mm,10 μm)作为固定相,水和乙腈作为流动相,进行梯度洗脱,以紫外触发模式收集馏分,共得到15个组分。二维反相色谱选择C18色谱柱(250 mm×20 mm,5 μm)作为固定相,水和乙腈作为流动相,进行梯度洗脱,最终得到14个高纯度化合物,并通过质谱和核磁共振对其进行确认。实验结果表明,该法具有良好的正交选择性,可以有效提高分离度和峰容量,对于分离络石藤等复杂样品具有重要意义。

Abstract:

A preparative two dimensional hydrophilic interaction liquid chromatography/reversed-phase liquid chromatography (Pre-2D-HILIC/RPLC) method was established to separate and purify the components in Trachelospermum jasminoides. The pigments and strongly polar components were removed from the crude extract after the active carbon decolorization and solid phase extraction processes. A Click XIon column (250 mm×20 mm, 10 μm) was selected as stationary phase and water-acetonitrile as mobile phases in the first dimensional HILIC. Finally, 15 fractions were collected under UV-triggered mode. In the second dimensional RPLC, a C18 column (250 mm×20 mm, 5 μm) was selected and water-acetonitrile was used as mobile phases. As a result, 14 compounds with high purity were obtained, which were further identified by mass spectrometry (MS) and nuclear magnetic resonance (NMR). Finally, 11 lignan compounds and three flavonoid compounds were obtained. The method has a good orthogonality, and can improve the resolution and the peak capacity. It is significant for the separation of complex components from Trachelospermum jasminoides.

Key words: Trachelospermum jasminoides, hydrophilic interaction liquid chromatography (HILIC), reversed-phase liquid chromatography (RPLC), separation and purification, two dimensional (2D) chromatography
