在农业中循环利用的水有制药污染的风险. 这项研究量化了农作物中的药用活性化合物 (PhAC),发现植物吸收和转移的多样性,pH没有显著影响.
科学领域:
- 环境化学环境化学
- 农业科学 农业科学
- 食品安全 食品安全
背景情况:
- 全球气候变化需要为农业回收水.
- 回收水中的药物对食物链构成风险.
- 了解农作物中药物的吸收对于食品安全至关重要.
研究的目的:
- 量化飞机培养作物的药用活性化合物 (PhAC) 和代谢物.
- 评估PhAC植物吸收和转移的潜力.
- 为了评估pH对植物PhAC积累的影响.
主要方法:
- 开发并验证了一种溶剂提取和LC-HRMS方法,用于PhAC和代谢物量化.
- 在三种植物物种中分析了9种药物和9种代谢物.
- 在三种不同的pH值下进行了空气体试验.
主要成果:
- 建立了一种快速可靠的方法来确定植物中的PhAC (1020,000 ng g−1,LOD 0.49.0 ng g−1).
- 卡巴马西平在菜叶中积累的比在古古拉中的更多.
- 硫甲醇和克林达米辛的根积分高于叶子积累,没有显著的pH影响.
结论:
- 经过验证的方法有效量化了植物中的PhAC和代谢物.
- 植物对PhAC的吸收和转移因化合物和植物物种而异.
- 测试的pH值并没有显著影响研究植物的PhAC吸收.

Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
