概括
许多大麻 (CBD) 化品标签不准确,其中一些含有非法水平的四大麻 (THC). 一种HPLC-UV-MS/MS方法准确地量化化品中的大麻素,揭示了广泛存在的标签问题.
科学领域:
- 分析化学 分析化学
- 化品科学 化品科学
- 药理学 药理学是指药理学的学科.
背景情况:
- Cannabidiol (CBD) 越来越多地用于化品,但产品质量和准确的标签是令人担忧的.
- 许多CBD注入的化品不符合广告内容或含有非法水平的四大麻素 (THC).
- 需要可靠的分析方法来确保含有大麻素的化品的安全性和有效性.
研究的目的:
- 开发和验证HPLC-UV-MS/MS方法,用于量化油入水化品乳液中的五种主要大麻素.
- 评估捷克市场上可用的化品中CBD标签的准确性.
- 强调需要改善化品行业对大麻素含量的监管合规性.
主要方法:
- 开发一种HPLC-UV-MS/MS方法,用于量化大麻 (CBD),大麻酸 (CBDA),四大麻 (THC),四大麻酸 (THCA) 和大麻基醇 (CBG).
- 使用异醇分散的样品提取,然后用Bond Elut Plexa PAX弹进行固态提取.
- 方法的验证,包括确定量化极限 (LOQ) 和校准范围,并比较带有和没有净化的矩阵效应.
主要成果:
- 开发的HPLC-UV-MS/MS方法在固相提取 (011%抑制) 后与未净化样品 (084%抑制) 相比,显示了减少的矩阵效应.
- LOQ为0.1 mg/g,对CBD的校准范围为0.150 mg/g,对其他分析物的校准范围为0.110 mg/g.
- 对36个化品样本的分析显示,只有36% (共14个中的5个) 准确地反映了标记的CBD含量,一个样本含有大量THC (0.16 ± 0.01 mg/g).
结论:
- 经过验证的HPLC-UV-MS/MS方法对于在化品乳液中准确量化大麻素是有效的.
- 在分析的化品中,很大一部分的CBD标签不准确.
- 这些发现强调了含有大麻素的消费品的错误标签的普遍性,并强调了加强化品行业监管和合规的必要性.

Capillary Electrophoresis: Applications
330
Capillary electrophoretic separations offer various modes, each with unique applications. These modes include capillary zone electrophoresis, capillary gel electrophoresis, capillary array electrophoresis, capillary isoelectric focusing, capillary isotachophoresis, micellar electrokinetic chromatography, and capillary electrochromatography.
Capillary zone electrophoresis (CZE) separates ionic components based on their electrophoretic mobility. It has been used to separate proteins, amino acids,...

High-Performance Liquid Chromatography: Elution Process
419
In High-Performance Liquid Chromatography (HPLC), the elution process is critical to the separation of analytes and the quality of chromatographic results. Elution describes how compounds move through the column and separate based on their interactions with the mobile and stationary phases. This process determines the resolution, peak shape, and retention times in the chromatogram, which are essential for identifying and quantifying components in complex mixtures. Understanding the elution...
