Clinica Chimica Acta:如何验证口腔液中大麻素的液相色谱-串联质谱分析方法

2019-08-06 Gladiator MedSci原创

本研究建立了液相色谱串联质谱法用于量化口腔液中的十种大麻素(<span lang="EN-US" style="font-size:12.0pt;mso-bidi-font-size:14.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;; mso-fareast-font-family:宋体;mso-bidi-font-fam

本研究建立了液相色谱串联质谱法用于量化口腔液中的十种大麻素(OF)的分析方法。该方法利用Quantisal™装置收集的OF并同时量化大麻酚(CBN),大麻二酚(CBD),Δ9-四氢大麻酚(THC),11-羟基-Δ9-THC11-OH-THC),11-nor-9 - 羧基-Δ9-THCTHC-COOH),11-去甲-9-羧基-Δ9-THC葡糖苷酸(THC-COOH-gluc),Δ9-THC葡糖苷酸(THC-gluc),大麻酚(CBG),四氢大麻黄素(THCV )和Δ9-四氢大麻酚酸ATHCA-A)。使用Oasis Prime HLB 30mg 96孔板优化固相萃取。通过BEH C18柱上的液相色谱分离大麻素,并通过Waters TQ-S微串联质谱仪检测。 CBNCBDTHC11-OH-THCTHC-glucTHCV的定量下限(LLOQ)为0.4ng / mL; THC-COOHTHC-COOH-glucCBGTHCA-A的含量为1.0ng / mL。对于THC,线性范围扩展至2000ng / mL,对于所有其他分析物,线性范围扩展至200ng / mL。在三个质量控制水平(QC)的日间分析偏差和不精确度在±15%之内。平均提取效率范围为26.0-98.8%。使用从随机分配到吸烟及THC含量<0.1%,5.9%或13.4%的个体收集样品测试该方法的适用性。该方法能够识别和计算经该方法验证的10种大麻素中6种的浓度。
