Abstract: leaves.The optimized conditions were extract with ethyl alcohol,ultrasound-assisted oscillate for 15 minutes,ratio of sample to solvent 1∶20,extraction 3 times.Meanwhile,the purification process of cannabidiol was also studied.The adsorption and elution capacity of cannabidiol by macroporous adsorption resin were investigated.The optimized macroporous adsorption resin is DM130.The product was characterized by HPLC,LCMS and HNMR.Finally,the cannabidiol of extracting and purification was established.
