Grapefruit juice was extracted into methylene chloride and chromatographed by HPLC, and the effect of the HPLC eluent on CYP3A activity was assessed by measuring 6beta-hydroxytestosterone formation in rat liver microsomes.

An analytical method using electrospray ionization and high-performance liquid chromatography/tandem mass spectrometry (LC/ESI-MS/MS) was developed to quantify vincristine and M1, the CYP3A-mediated metabolite of vincristine, in human plasma.
Vinblastine (internal standard), vincristine, and M1 in plasma were extracted in methylene chloride after acidification with TCAA.

The reproducibility and sensitivity of the assay, combined with the selectivity of mass spectrometric detection, should allow an accurate kinetic characterization of terfenadine oxidation mediated by the high affinity CYP3A enzymes in human liver and intestinal microsomes.
Terfenadine metabolites were extracted from basified microsomal incubates into methylene chloride.

J Chromatogr B Biomed Sci Appl. 1999 Oct 29;734(1):73-81.

The assay has been used to characterize the CYP3A metabolic activity of multiple preparations of human, rat, and dog liver microsomes.
Testosterone and its metabolites are extracted from the incubation mixture in a single step with methylene chloride.
