摘要: 单体花色苷的快速大量制备长久以来是花色苷产业化中的难题,而中压制备液相色谱在产业应用中有着很大的开发空间。选取花色苷组分较单一的桑葚为实验原料,经提取分离总花色苷后使用填装有反相C18填料的耐压玻璃柱作为中压制备液相色谱柱,纯化制备矢车菊素-3-葡萄糖苷单体。结果显示:3 个色谱分离峰中目的峰(峰2)经高效液相色谱和质谱确证为由矢车菊素-3-葡萄糖苷(cyanidin-3-glucoside,C3G)和矢车菊素-3-芸香糖苷(cyanidin-3-rutinoside,C3R)组成,采用峰面积归一化法计算得到C3G纯度为73.56%;通过对峰2采用切割方式进行收集,C3G纯度达到98%以上,单次收集到C3G单体溶液650?mL。中压制备液相色谱法单次上样量大、步骤简洁、成本低廉,可为矢车菊素-3-葡萄糖苷单体的规模化生产提供一定的参考。

Abstract: Rapid large-scale preparation of monomeric anthocyanins has always been a problem in the industrialization of anthocyanins. Preparative medium pressure liquid chromatography (MPLC) has great potential for application in the food industry. Cyanidin-3-glucoside (C3G) was purified by preparative MPLC using a C18 column from the anthocyanins extracted from mulberry fruit, containing only a few kinds of anthocyanins. The results showed that a total of three chromatographic peaks were separated. The second peak was confirmed to be composed of cyanidin-3-rutinoside (C3R) and C3G by high performance liquid chromatography (HPLC) and mass spectrometry (MS), and C3G accounted for 73.56% of the total amount as calculated by the peak area normalization method. The purity of C3G was over 98% when the peak was collected in several fractions, and a total of 650 mL of C3G was obtained in one operation. The preparative MPLC method has the advantages of large sample loading volume, simple operation and low cost and can provide a useful tool for rapid and large-scale production of C3G.
