Δ9-THC (11). The chemical structures of the purified compounds were determined using several spectroscopic methods, including 1D (1H, 13C, and DEPT-135) and 2D (COSY, HMQC, HMBC, and NOESY) NMR, LC–MS, and GC-MS. Other naturally occurring cannabinoids and impurities were also identified in GC-MS chromatograms but were not isolated. These were cannabidiol (CBD, 12), cannabinol (CBN, 13), hexahydrocannabinol
使用 GC-MS对几种含有 Δ 8 -四氢大麻酚 (Δ 8 -THC) 作为主要成分的商业产品进行定性分析,结果鉴定出了几种杂质以及 Δ 8 -THC。为了尝试分离和鉴定这些杂质,选择商业 Δ 8 -THC 馏出物进行分离工作。使用多种色谱技术分离出十一种杂质,并确定了它们的化学结构。这些包括 Δ 4,8-异-四氢大麻酚 ( 1 ) 、Δ 4-异-四氢大麻酚 ( 2 )、Δ 8-顺式-异-四氢大麻酚 ( 3 )、4,8-环氧-异-四氢大麻酚 ( 4 )、8-羟基-异-四氢大麻酚 ( 5 )、9β-羟基六氢大麻酚 ( 6 )、9α-羟基六氢大麻酚 ( 7 )、异-四氢大麻呋喃 ( 8 )、大麻西群 (CBT, 9 )、橄榄醇 ( 10 ) 和 Δ 9 -THC ( 11 )。使用多种光谱方法确定纯化化合物的化学结构,包括 1D ( 1 H, 13C、DEPT-135)和 2D(COSY、HMQC、HMBC
