If shatter/oil is 90% total cannabinoids, what is the other 10%?

I know this is sort of a basic question, but I can't find solid information on this. Any pros/extraction artists/chemists know? Much appreciated.

Plant waxes, lipids proteins(?) and such.

Also getting 90% purity i think is only achievable if you dewax... I doubt i could get much higher than 80% without dewaxing.... i could be wrong tho

You are extracting a range of terpenes ranging from C-10 monoterpenes, through C-30 triterpenes, as well as plant waxes, anthro cyanin plant pigments, and chlorophyll. The cannabinoids are based on the C-20 diterpene (C-21 phenolic terpenoid).
