separate mitragynine from kratom resin?

[bassdude]

Does anyone know the process of separating the mitragynine alkaloid
from kratom extract. How do you refine it or separate the alkaloid from
the plant waxes, oils and tannins? I use and iso-2 to extract the
resins using ethyl alcohol but I need to know how to process it
further. Does the process that you use for salvia d. which is naptha
which absorbs the plant waxes and tannins and leaves the salvinorum A
work with kratom? I need a reply from someone who really knows his or
her sh#t. Thanks
