Morphology

extractant = extract (semi-transparent) = ex + tract + ant

The relation to 'extract' is clear, but the technical substance sense of '-ant' is specialized and not fully predictable for many learners.

Etymology

The word extractant comes from the parts ex- meaning 'out' and tract meaning 'pull', the same root you see in tractor and in the verb extract. So an extractant is a substance often used as a liquid to 'pull out' a specific part from a mixture.
