Abstract

The present invention relates to a method of extracting cannabinoids and terpenes from cannabis flos comprising the steps of loading cannabis flos into a vacuum oven to produce vapour and biomass; collecting and condensing the vapour produced; separating terpenes from the condensed liquid and storing the collected terpenes for further use; removing the biomass from the oven and adding ethanol chilled to a temperature between -35 and -45°C to form a biomass ethanol mixture, percolating the ethanol solution through the mixture multiple times, keeping the solution at about - 40 to -50°C; removing solid material from the mixture to leave a crude oil tincture; filtering the tincture to remove unwanted components; evaporating ethanol from the filtered crude oil and ethanol mixture at a temperature not exceeding 100°C; decarboxylating the crude oil by thin layer heating at 120 °C to obtain a crude extract with a THC content of at least 65 w/w%; subjecting the crude extract to a plurality of wiped film distillations; blending the film wipe distillation fractions to obtain a purified extract with a THC concentration of at least 75 w/w%; and adding the collected terpenes to the purified THC extract.
