HPLC chromatograms of extracts and isolated Phytocannabinoids. A is the hexane extract, B is the acetyl acetate extract, C is THC, D is CBN and Panel E is THCA. The analysis was performed with a 20 μL sample injection in a Kromasil 100–5-C8 (4.6 × 150 mm) column with a water:acetonitrile (20:80) mobile phase at 1.0 mL/min. The detection was performed with an UV detector at 272 nm [12]
