A simple, quick and low cost procedure was developed for the extraction of Δ⁹-tetrahydrocannabinol, cannabidiol, and cannabinol from marijuana samples, based on the use of a hard-cap espresso extraction with 2-propanol. After extraction, cannabinoids were directly determined after appropriate dilution by gas-chromatography-mass spectrometry, reaching a limit of detection from 0.03 to 0.05 mg g⁻¹. Extraction efficiency was evaluated by the comparison of results obtained for seized samples by the proposed method and a reference methodology based on ultrasound-assisted extraction. Moreover, ion mobility was proposed for the rapid and sensitive determination of Δ⁹-tetrahydrocannabinol and cannabidiol providing a quick response for the analysis of seized marijuana samples in 1 min, including extraction, dilution and determination.

一种简单，快速和低成本的步骤，对于Δ的提取开发⁹四氢大麻酚，大麻二酚，和大麻酚从大麻样品，基于使用硬帽浓咖啡提取用2-丙醇。提取后，通过气相色谱-质谱法适当稀释后直接测定大麻素，检出限为0.03至0.05 mg g ^-1。通过比较建议的方法和基于超声辅助提取的参考方法获得的检出样品的结果来评估提取效率。此外，离子迁移，提出了快速和灵敏的测定Δ的⁹-四氢大麻酚和大麻二酚可在1分钟内快速分析缉获的大麻样品，包括提取，稀释和测定。
