The hemp plant consists of the woody part (44% of the plant weight), fibres (24%), seeds (11%) and other components such as flowers, leaves and dust (21%) [ 1 3 ]. Since each part of the hemp has its own potential for a certain product, the main thing in planning is the pretreatment of the material (for example, the screening method), which separates plant parts. Certain known forms of leaves also constitute a part of the plant and are located above the cola from which the flower emerges [ 4 ]. Nonacidic forms of cannabinoids (CBD, THC, CBG, etc.) The extraction of raw material results in the acidic form of cannabinoid compounds and decarboxylation is required to obtain nonacidic forms [ 22 ].
