技术领域
本发明属于大麻酚类加工领域，特别涉及一种同时分离次大麻二酚和大麻萜酚的方法。
背景技术
次大麻二酚(Cannabidivarin)分子式是C19H26O2。次大麻二酚存在于工业大麻中。将工业大麻经过醇浸提等，即可得到含次大麻二酚的浸膏。次大麻二酚(CBDV)可用于神经病症的治疗。
大麻萜酚(Cannabigerol)分子式是C21H32O2。大麻萜酚存在于工业大麻中。将工业大麻经过醇浸提等，即可得到含大麻萜酚的浸膏。大麻萜酚(CBG)可用于神经病症的治疗。
利用高速逆流色谱同时分离次大麻二酚和大麻萜酚与分离大麻二酚的不同在于，采用了不同的溶剂体系，以使得次大麻二酚和大麻萜酚得到更好的分离效果。
高速逆流色谱(HSCCC)技术是一种新的基于液液分配原理的分离纯化技术，它不需要任何固态支撑或载体，固定相和流动相皆为液体，无不可逆吸附。

本发明提供了一种同时分离次大麻二酚和大麻萜酚的方法，包括：
将溶剂体系充分振摇，静置，分开收集上、下两相；将工业大麻全谱系精制油溶解于上相中，以上相为固定相，下相为流动相，采用高速逆流色谱进行分离，分别得到次大麻二酚与流动相的混合液、大麻萜酚与流动相的混合液，去除流动相，得到次大麻二酚、大麻萜酚；
其中，溶剂体系由正己烷或正庚烷、甲基叔丁基醚、乙腈或乙醇、水按体积比为5～10：1～3：5～10：2～4混合而得。
所述分开收集得到的上、下两相进行超声脱气处理。
所述高速逆流色谱的条件为：转向为正转，转速为800rpm；柱温为25℃；流动相的流速为5mL/min；检测器的检测波长为214nm。
所述去除流动相的工艺条件为：在55℃、-0.085MPa条件下进行旋转蒸发真空干燥。
本发明所述溶剂体系由次大麻二酚和大麻萜酚在互不相溶的两相溶剂中的溶解度而定。
有益效果
