Abstract
Δ-THC acid is extracted fromflowers using a first organic solvent, then separated using a second aqueous solvent. Δ-THC acid is converted to Δ-THC carboxylic salt before being extracted by a third organic solvent and converted back to Δ-THC carboxylic acid. Using a solvent swap, Δ-THC carboxylic acid is decarboxylated and extracted again with an organic solvent prior to purification to give Δ-THC.
