Derivatization is the most powerful contribution to the identification and quantification of plant cannabinoids (p-CBDs) by gas chromatography-mass spectrometry (GC-MS): providing volatile derivatives with eminent properties (high selectivity, outstanding sensitivity and mass spectrometric peculiarities). These derivatives are excellent candidates to determine the main p-CBDs, like tetrahydrocannabivarin (THCV), tetrahydrocannabidivarin (CBDV), cannabidiol (CBD), cannabichromene (CBC), cannabicyclol (CBCL), tetrahydrocannabinol (THC), cannabigerol (CBG), cannabinol (CBN), 11-hydroxy-Δ9-THC (11-OH-THC) and 11-nor-9-carboxy-THC (THC-COOH). Identification and quantification of p-CBDs is required - partly as trace constituents in complex biological matrices of drug users, partly as main components in seizure samples: in both cases, in extremely different ratios. GC proposals published between 2000 and 2017, along with outstanding pioneer contributions, are reviewed. Procedures, without derivatization and applying various alkylsilyl, acylation and/or esterification techniques were listed, compared and criticized. Further sorting was based on the reagent type, on examined matrices, on enrichment/detection related acquisition protocols and on analytical performance characteristics.

衍生化技术在气相色谱质谱法分析植物大麻素中的作用

衍生化是通过气相色谱-质谱(GC-MS)鉴定和定量植物大麻素(p-CBD)的最有力贡献:提供具有卓越性能(高选择性,出色的灵敏度和质谱学特性)的挥发性衍生物。这些衍生物是确定主要p-CBD的极佳候选者,如四氢大麻酚(THCV),四氢大麻酚(CBDV),大麻二酚(CBD),大麻二烯(CBC),大麻二环(CBCL),四氢大麻酚(THC),大麻二酚(CBG),大麻酚(CBN),11-羟基Δ 9-THC(11-OH-THC)和11-nor-9-羧基-THC(THC-COOH)。对p-CBD的鉴定和定量是必需的-部分是吸毒者复杂生物基质中的痕量成分,部分是癫痫发作样品中的主要成分:在两种情况下,比率都极为不同。审查了2000年至2017年期间发布的GC提案以及杰出的先驱贡献。列出,比较和批评了没有衍生化并且应用各种烷基甲硅烷基的方法,酰化和/或酯化技术。根据试剂类型,所检查的基质,与富集/检测相关的采集规程和分析性能特征进行进一步分选。
