Abstract

This research studied four cultivars of Cannabis sp. The results of the study classified the cultivars according to their cannabinoids composition of THC (tetrahydrocannabinol), CBD (cannabidiol) and CBG (cannabigerol) into four types (type I (THC dominant), type II (hybrid), type III (CBD dominant) and type IV (CBG dominant). These cultivars were the Thai stick, the King garden, the Charlotte’s angle, and the CBD zerodue, respectively. The total phenolic contents showed that the King garden cultivar had the highest level at 1033.60±9.42 mgGAE/g extract. The antioxidant activity, measured using the DPPH and ABTS assays, indicated that the King garden cultivar had the best antioxidant activity with EC50 values of 15.06±0.73 and 0.50±0.10 mg/mL, respectively. Moreover, it was found that the antioxidant activity was related to the total phenolic contents of each cultivar. The study of anti-inflammatory effects using protein denaturation inhibiting assay found that the CBG zerodue cultivar had the best effect, inhibiting protein denaturation by 57.51% at a concentration of 500 ug/mL.
