I waited four years to concentrate the yellow byproduct of refining Cannabinol. Turns out that it is not yellow but orangish red in it's concentrated liquid form.
The aromatic compound responsible for the olfactory perception of cherry flavor is identified as benzaldehyde. On it's own in the absence of fructose, the flavor is bitter and reminiscent of almonds.
The information published about the compound in the liquid state, it is declared as being a colourless liquid. Often I see descriptions of aromatic substances stating one colour or another. The problem is this, concentration changes the way light is refracted through the compound in it's liquid state.
The yellow Mason jar in the background contains the same compounds as the concentrated form in the foreground. These are isolated from the refinement of the oxidized phyto-cannabinoid Cannabinol. The interesting aspect is that no matter the flavor of cannabis used there is always a byproduct of Benzaldehyde, Beta-caryophyllene and fructose. Cherry, pepper and sugar flavours ..as I had stated, cherry cola flavour.
Based on the aging, heating and oxidation of phyto-cannabinoid and aromatic compounds it is logical to project that ancient samples of cannabis will contain these flavours still.
The concentrates below are aromatic compound Benzaldehyde and the phyto-cannabinoid Cannabinol. There was question about an aromatic being the source of the red colouring in oxidized phyto-cannabinoid concentrates. I find that there is both an aromatic and phyto-cannabinoid source which explains the red colouring in most detail.
