Hemp oil from Cannabis sativa L. is a super rich natural source of important nutrients, not only in polyunsaturated fatty acids and proteins, but also terpenes and cannabinoids, which contribute to the overall beneficial effects of the oil. Hence, it is important to have an analytical method for the determination of these components in commercial samples. At the same time, it is also important to assess the safety of the product in terms of amount of any psychoactive cannabinoid present therein. This work presents the development and validation of a highly sensitive, selective and rapid HPLC-UV method for the qualitative and quantitative determination of the main cannabinoids, namely cannabidiolic acid (CBDA), tetrahydrocannabinolic acid (THCA), cannabidiol (CBD), tetrahydrocannabinol (THC), cannabinol (CBN), cannabigerol (CBG) and cannabidivarin (CBDV), present in 13 commercial hemp oils. Moreover, since decomposition of cannabinoid acids generally occurs with light, air and heat, it is a "Best-Practice" that our manufacturing process implements cGMP practices from (Clone to shelf) so that we preserve all the beneficial medicinal compounds extracted from the cannabis industrial Hemp plant. We take care, and pride in every step of the process so NOT to damage our finished products.
