To select the optimum extracting procedure for cannabinoids from hemp seed oil.


The optimum extracting procedure was selected with the content of cannabinol and delta9-tetrehydrocannabinol from hemp seed oil by orthogonal test design. We have examined three factors that may influence the extraction rate: the time of extraction, the times of extraction and the amount of methanol.


The optimum extraction condition was adding 5 ml, two times amount of methanol into hemp seed oil for 15 min.


The above extraction process gave the most rational, stable, feasible and satisfactory results. The method is convenient.
