Analyzing the highs and lows of cannabis derivatives with FTIR
A wide variety of cannabis derived products are now available for purchase, although the legality of these products varies from country to country. Within Europe, products containing more than 0.2% tetrahydrocannabinol (THC) are banned, however cannabidiol (CBD) containing products are legal. This note compares the FTIR spectra obtained from two such legal products.
Method
Two commercially available Cannabidiol (CBD) food supplements were obtained. One was specified as 5% CBD, whilst the other contained 2.75% CBD. The ingredients list for both products contained Hemp seed oil and Hemp paste, whilst the lower strength product also contained sunflower lecithin. The two samples were placed in a 25 μm wedged CaF2 oyster cell and spectra of the samples recorded on a commercially available spectrometer.
