  • Title: Solid-phase extraction, identification, and quantitation of 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid.
    Author: Nakamura GR, Meeks RD, Stall WJ.
    Journal: J Forensic Sci; 1990 Jul; 35(4):792-6. PubMed ID: 2167920.
    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.
