Solid-Phase Extraction, Identification, and Quantitation of 11-Nor-Delta-9-Tetrahydrocannabinol-9-Carboxylic Acid

CODEN: JFSCAS

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.
