    Author: Zhang G, Guo J, Bi K.
    Journal: Zhong Yao Cai; 2005 May; 28(5):417-8. PubMed ID: 16131037.
    Abstract:
    OBJECTIVE: To select the optimum extracting procedure for cannabinoids from hemp seed oil. METHODS: 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. RESULTS: The optimum extraction condition was adding 5 ml, two times amount of methanol into hemp seed oil for 15 min. CONCLUSION: The above extraction process gave the most rational, stable, feasible and satisfactory results. The method is convenient.
