Excellent work DVap, great real information.
mega thanks for putting in all the time, cost and effort & expertise
Could be the e-juice of the future has just been born,
well with a bit more characterisation maybe...
So if the x-factor is truly 'other alkaloids' (or anything else you've extracted),
rather than psychosomatic, actual MOAI or CO, whatever,
then this could be just what I'm needing to get me off ciggies (again).
MAOIs are any chemical with the activity of inhibiting the enzyme mono-amine oxidase, thereby allowing dopamine, for example (one of the mono-amine neurotransmitters), to rise. Some tobacco alkaloids are MAOIs. Allaloid is a chemical classification whereas MAOI is a functional classification.
So the pure nicotine was rather a cul-de-sac ultimately. However, entertaining the idea of purity was raised and the consideration of what should and should not be used in e-liquid. Slowly the awareness of thinking through the merits of flavorings and additives has been increased and that is good.
The focus on just nicotine has been around for a long-time, long before e-cigs. But the evidence that the pleasure of smoking involved more than just nicotine was also there.
This error is often made when drugs based on natural remedies are pursued, and often (though not always) the single chemical is not as effective (or safe) as the natural extract as a whole (multi-chemical). In the case of tobacco, it is somewhere in the middle: we only need one part, but that part is a family of chemicals rather than a single chemical.
The good news is that extracting the alkaloids is easier than etracting just nicotine. The bad news however is that no one is doing that right now (?; whether Dekang liquids are based on alkoloids or just nicotine is unclear; we are assuming it is based on only nic, but it's not certain, afaik). If the amount ordered was right, the companies supplying pure nicotine could certainly supply mixed alkaloids (if not already on the shelf). Perhaps it is a step along the way to making pure nicotine, and could therefore be made available easily and quickly.
Although the contexts are different, consider, for example vitamin E. Most vitamin E pills are only alpha tocotrienol, the "most active" tocotrienol. However, there are a family of tocotrienols and they do slightly different things. When the alpha is in excess of it's normal preponderance, it actually inhibits the activity of the gamma type. The 'scientific' studies that show no or little benefit to taking extra vitamin E always use only the alpha form. Tobacco alkaloids are made by plants as a defence from pests, not for human benefit of course, but I think my point by analogy is clear. For some people (maybe small as a %), just nic may actually be worse than not getting either nic or the other alkaloids.
btw, I've always thought the CO to be a red-herring; it contributes only to the grogginess following over-smoking, not a good feeling, and a drain on the body's resources.
DVap - anything else, besides alkaloids, that might have been extracted using the acid/base exchanges? I'm sure you have thought about this already, but people will ask this and it's a reasonable question.
