Hello, I am interested in analyzing the chemical components which make up nicotine, but I've had difficulty finding information. I've found a plethora of information on how to synthesize nicotine, but not in reversing the process and extracting the base components from nicotine. Here is basically what I'm trying to do:

Perform X on nicotine to reduce to base chemicals, which I theorize are nicotinic acid and some variation of N-methyl-pyrrolinium. I wish to then separate the N-methyl-pyrrolinium (or some form of pyrrolinium) from the nicotinic acid, and analyze each of the chemicals extracted. Is it even theoretically possible to extract the nicotinic acid without destroying the remaining chemicals used in nicotine synthesis? Thank you in advance.

Here is some information I've gathered so far:
Nicotine: 3-[(2S)-1-methylpyrrolidin-2-yl]pyridine (C10H14N2)
Nornicotine: 3-Pyrrolidin-2-ylpyridine (C9H12N2)
nicotinic acid: 3-Pyridinecarboxylic acid (C6H5NO2)
N-methyl-pyrrolinium: (C5H10N+)

I'm also interested in what other types of chemicals besides nicotine are commonly found in the tobacco product itself.
