Norephedrine extraction

[comus]

I haven't had a Merk Index for over a week so I am here asking, what solvents are needed to separate norephedrine HCl from yohimbine HCl and caffeine?

I don't think a solvent extraction will be enough for that, if the norephedrine is present to a much greater extent than the other ingredients, maybe repeated recrystallizations will help.
