Abstract:
Hemp is among the oldest plants known in traditional medicine and one of the most phytochemically studied. The psychoactive phytocannabinoid in acid form (THCA) is most concentrated in the inflorescences. During harvesting and cleaning of the seeds, there could be contamination with parts of the plant containing THCA, and therefore there could also be this metabolite in the oil, which could undergo the process of decarboxylation to become psychoactive THC. The aim of this study was to identify the levels of THC present in hemp seed oil of the Uso-31 variety extracted by cold pressing at two different temperatures (40°C and 70°C) and at two different pressures using the diameter nozzles of (8mm and 12mm). The experimental field was divided into eight plots cultivated with different agronomic practices in order to evaluate the influence of these on the amount of THC. Chemical analysis of the oil showed a THC presence of less than 5 mg/Kg.
