This work reports about a screening of four adsorbents with different polarity employed for the separation of the main phytocannabinoids contained in Cannabis sativa L., under normal phase liquid chromatography (NPLC). The effect of polarity and type of interaction mechanisms of the adsorbents (namely Si-, CN-, Diol-, and NH-based SPs) on retention has been investigated under a variety of conditions either by using different combinations of apolar solvents (heptane or hexane) and alcohols (ethanol or isopropanol). The columns have also been employed for the separation of a real cannabis sample. Graphical Abstract Investigating the effect of polarity of stationary and mobile phases on retention of cannabinoids in normal phase liquid chromatography.
本工作报道了四种不同极性的吸附剂在正相液相色谱(NPLC)中用于分离大麻中主要植物大麻素的筛选。考察了吸附剂(即 Si-、CN-、二醇-和 NH 基 SP)的极性和相互作用机制类型对保留的影响,方法是在各种条件下使用不同的非极性溶剂(庚烷或己烷)和醇(乙醇或异丙醇)组合。这些柱子还被用于分离真实的大麻样品。
