A method was established for purification of limonin, nomilin, and isoobacunoic acid simultaneously from segment membranes of pomelo (Citrus Grandis). This method includes 3 steps, removing most impurities by macroporous resin HZ-816, isolating limonin by High Speed Counter Current Chromatography (HSCCC), and isolating nomilin and isoobacunoic acid by semi-preparative HPLC. Naringin was partially purified as a by-product of this process using Sephadex LH-20. All limonoids purified through this method reached 95% purity. The purified limonin, nomilin and isoobacunoic acid were identified according to the retention time of the standard substances using HPLC and characteristic fragment ions of LC-MS/MS.

建立了一种从柚子(Citrus Grandis)囊衣中同时纯化柠檬苦素、诺米林和异obacunoic酸的方法。该方法包括3个步骤,通过大孔树脂HZ-816去除大部分杂质,用高速逆流色谱法(HSCCC)分离柠檬苦素,并用半制备高效液相色谱法分离诺米林和异obacunoic酸。柚皮苷作为该过程的副产物使用葡聚糖凝胶LH-20进行部分纯化。通过该方法纯化的所有柠檬苦素类化合物纯度达到95%。使用高效液相色谱法根据标准物质的保留时间以及液相色谱-串联质谱法(LC-MS/MS)的特征碎片离子对纯化的柠檬苦素、诺米林和异obacunoic酸进行鉴定。
