Abstract:

The aim is to study the dynamic changes of CBD and CBDA contents of Cannabis sativa L. after fermentation, clarify the correlation between CBD and CBDA, and provide reference for efficient production of CBD raw materials. With CBD and CBDA as indexes, Cannabis sativa L. were fermented by Saccharomyces cerevisiae, Lactobacillus plantarum, Escherichia coli and endophytic bacterium WF17, respectively. The dynamic changes of CBD and CBDA contents of Cannabis sativa L. before and after fermentation were analyzed by HPLC method. The CBD content reached the maximum value (3.1161 mg/g) on the first day after the fermentation of Cannabis sativa L. by Saccharomyces cerevisiae. The CBD content reached the maximum value (3.7786 mg/g) on the 9th day after Lactobacillus plantarum fermentation of Cannabis sativa L.. The content of CBD reached the maximum value (3.5502 mg/g) at 3 d after fermentation of Cannabis sativa L. by Escherichia coli. After the fermentation of Cannabis sativa L. by endophytic bacteria WF17, the CBD content reached the maximum value (3.9182 mg/g) at the fermentation time of 7 days. The content of CBDA decreased the most in the first day of fermentation. All the four fermentation strains could significantly increase the CBD content and decrease the CBDA content in the fermented Cannabis sativa L. to a certain extent, and there might be a process of CBDA to CBD in the fermentation process of Cannabis sativa L.. Therefore, fermentation technology can be used for efficient production of CBD in Cannabis sativa L..

Key words: Cannabis sativa L., cannabidiol, cannabidiolic, fermentation, HPLC
