Search this Article
Cannabis oil (1 g) was extracted with n-hexane-saturated acetonitrile, and 91% of oil was removed by this method. Cannabinoids in extracted cannabis oil were identified by high performance thin layer chromatography (HPTLC) and capillary gas chromatography-mass spectrometry (GC-MS). The cannabinoid contents were determined by capillary gas chromatography (GC) using 5α-cholestane as an internal standard. Contents of CBD in the cannabis oil were 121±17 μg/g. However, other cannabinoids (THC and CBN) were not detected in this cannabis oil by HPTLC, GC-MS or GC.
