摘要 建立了制备型凝胶渗透色谱(GPC)技术制备毫克量级的氧化三酰甘油二聚物(TGD)和氧化三酰甘油寡聚物(TGO)的方法。首先,采用制备型快速柱层析(PFC),经FLASH柱分离出油脂极性组分(polarcompounds,PCs),45℃旋转蒸干,薄层色谱(TLC)验证PCs分离效果;然后,将PCs四氢呋喃溶液按4.2mL/min流速进入制备型凝胶渗透色谱系统,按照分子量大小的差异,对PCs中的TGO和TGD进行分离,然后根据这些物质出峰时间,分别进行收集。TGO、TGD的收集时间分别为29.00~32.10min、32.25~33.50min,收集的溶液45℃旋转蒸近干,0.1MP烘干30min。制取的TGD、TGO与原料PCs同步进行HPSEC分析,验证了各制备组分的真实性。
