Methods for making trans-(−)-Δ
9
-tetrahydrocannabinol and trans-(+)-Δ
9
-tetrahydrocannabinol are disclosed herein. In one embodiment, a trans-(−)-Δ
9
-tetrahydrocannabinol composition is prepared by allowing a composition comprising (±)-Δ
9
)-tetrahydrocannabinol to separate on a chiral stationary phase to provide a trans-(−)-Δ
9
-tetrahydrocannabinol composition comprising at least about 99% by weight of trans-(−)-Δ
9
-tetrahydrocannabinol based on the total amount of trans-(−)-Δ
9
-tetrahydrocannabinol and trans-(+)-Δ
9
-tetrahydrocannabinol. The invention also relates to methods for treating or preventing a condition such as pain comprising administering to a patient in need thereof an effective amount of a trans-(−)-Δ
9
-tetrahydrocannabinol having a purity of at least about 98% based on the total weight of cannabinoids.
本文公开了制备反式-(−)-Δ9-四氢大麻酚和反式-(+)-Δ9-四氢大麻酚的方法。在一种实施例中,通过让包含(±)-Δ9-四氢大麻酚的组成物在手性固定相上分离,制备出反式-(−)-Δ9-四氢大麻酚组成物,其中反式-(−)-Δ9-四氢大麻酚的重量占反式-(−)-Δ9-四氢大麻酚和反式-(+)-Δ9-四氢大麻酚总量的至少约99%。本发明还涉及治疗或预防疼痛等疾病的方法,包括向需要治疗的患者投与至少约98%纯度的反式-(−)-Δ9-四氢大麻酚,其基于大麻素总重量计算。
