Phytochemical investigation of the lipids extracted from seeds of Cannabis sativa by GC-MS showed 43 cannabinoids, 16 of which are new. The extract is dominated by Δ9-tetrahydrocannabinolic acid (A) and its neutral derivative trans-Δ9-tetrahydrocannabinol-C5 (THC) Cis and trans-Δ9-tetrahydrocannabinol-C7 isomers with an ethyl-pentyl branched chain together with minor amounts of trans-Δ9-tetrahydrocannabinol with a methyl-pentyl C6 branched side chain were identified as new natural compounds. Four cannabichromene isomers with a C5 side chain are postulated to be derived from the double bond migration at the terminal isoprenyl unit. C7 cannabichromene together with the neutral and acidic forms of cannabinol-C7 were also detected. The mass spectrum of these homologues as trimethylsilyl (TMS) derivatives are presented, and the fragmentation patterns are discussed.

高效能大麻中异常同源大麻素的 GC-MS 代谢物谱和鉴定

通过 GC-MS 对从大麻种子中提取的脂质进行的植物化学研究表明，有 43 种大麻素，其中 16 种是新的。提取物主要是 Δ9-四氢大麻酚酸 (A) 及其中性衍生物反式-Δ9-四氢大麻酚-C5 (THC) 顺式和反式-Δ9-四氢大麻酚-C7 异构体，带有乙基-戊基支链以及少量的反式-具有甲基戊基 C6 支链侧链的 Δ9-四氢大麻酚被鉴定为新的天然化合物。四种具有 C5 侧链的大麻二酚异构体被假定来自末端异戊二烯基单元的双键迁移。还检测到 C7 大麻酚以及中性和酸性形式的大麻酚-C7。显示了这些同系物作为三甲基甲硅烷基 (TMS) 衍生物的质谱图，
