Abstract
A procedure has been developed to extract and recover minute amounts of delta-9-carboxytetrahydrocannabinol (THC-COOH) from urine. A new non-isotopic internal standard is introduced to permit a chromatographic assay of the metabolite. The method affords a 91% recovery of 20 ng/mL of the THC-COOH acid from spiked urine with the assurance of a 3.8% coefficient of variation.
摘要
已开发出一种从尿液中提取和回收微量δ-9-羧基四氢大麻酚（THC-COOH）的方法。引入了一种新的非同位素内标，以便对该代谢物进行色谱分析。该方法从加标的尿液中回收20 ng/mL的THC-COOH酸，回收率为91%，变异系数为3.8%。
