Abstract
Official abstract text for this publication.
Provided are a method of preparing a cannabis processed product having an increased CBD content in an efficient and economic manner, through decarboxylic acid reaction by microwave irradiation of cannabis using various extraction solvents, and use of the processed product having an increased CBD content prepared by the method, a fraction thereof, and a single ingredient of CBD, in foods, drugs, and cosmetics.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of isolating cannabidiol from cannabis , consisting essentially of: a) subjecting a reaction mixture consisting essentially of cannabis and ethyl acetate in an airtight container to microwaves to yield a microwave irradiated reaction mixture; and b) isolating cannabidiol from the microwave-irradiated reaction mixture, wherein the microwaves are carried out at 50 W to 6 kW, a frequency of 300 MHz to 300 GHz, 80° C. to 150° C. and at a pressure of 2 atm to 100 atm for 5 minutes to 180 minutes.
