Abstract

Nineteen cannabinoids, including Δ⁹-THC (tetrahydrocannabinol) and CBD (cannabidiol), were quantified in 22 CBD oils, 2 CBG (cannabigerol) oils, and 2 CBN (cannabinol) oils, marketed as food supplements, aroma oils, or cosmetic preparations. Analyses were conducted using high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS). The declared concentrations of CBD (or CBG, CBN) in the oils ranged from 2.5 to 20%. Actual concentrations compared to declared concentrations ranged from 81 to 226%. CBD concentrations of up to 9 mg per drop were found. Δ⁹-THC was detected in 20 of 26 samples, with concentrations ranging from 5 to 1576 mg/kg (mean = 536 mg/kg). Considering the highest daily intake suggested by one manufacturer (20 drops) and a body weight of 70 kg, the measured Δ⁹-THC concentration in 50% (n = 13) of the products would exceed the acute reference dose (ARfD) of 1 µg/kg body weight (bw) derived for Δ⁹-THC by the European Food Safety Authority (EFSA). For 7 samples, only 2 drops of oil would be sufficient to exceed the ARfD of Δ⁹-THC.

全面分析商用 CBD 油中的 19 种大麻素：浓度、特征和安全影响

对 22 种 CBD 油、2 种 CBG（大麻酚）油和 2 种 CBN（大麻酚）油中的 19 种大麻素（包括 Δ9-THC（四氢大麻酚）和 CBD（大麻二酚））进行了定量分析，这些油在市场上作为食品补充剂、芳香油或化妆品制剂销售。分析采用高效液相色谱-串联质谱法（HPLC-MS/MS）进行。精油中 CBD（或 CBG、CBN）的申报浓度介于 2.5% 和 20% 之间。与申报浓度相比，实际浓度从 81% 到 226% 不等。发现每滴 CBD 的浓度高达 9 毫克。在 26 个样本中的 20 个样本中检测到了Δ9-四氢大麻酚，浓度从 5 毫克/千克到 1576 毫克/千克不等（平均值 = 536 毫克/千克）。考虑到一家生产商建议的最高日摄入量（20 滴）和 70 千克的体重，50% 的产品（n = 13）中测得的 Δ9-THC 浓度将超过欧洲食品安全局（EFSA）为 Δ9-THC 制定的急性参考剂量（ARfD），即 1 微克/千克体重。在 7 个样本中，只需 2 滴油就足以超过 Δ9-THC 的急性参考剂量。
