Ah that's more of what I meant alone, not for consumption but research, maybe it would help unlock better what chemotype 1, 3, and 6 do more fully or maybe it would let you play with chemo combinations to find an ideal category for each chemotype.A chemotype can be isolated just by drinking kava from a single batch of a specific cultivar. In other words, each serving from a single bag is normally the same chemotype. But if what you mean is: can you isolate a single kavalactone? Yes, that can be done, but it is very expensive. You can buy pure kavalactones, such as kavain, for a couple hundred dollars per gram. That is way too expensive for most people who are not extremely wealthy to test ingesting. Also the pure KLs are not sold for purposes of human consumption, but as testing standards. I have seen reports of people consuming pure kavain, and it is reported to have a stimulating effect, but I don't know of anyone who has tried to use pure samples of the other KLs on themselves. A problem with trying to test the effect of pure KLs--however--is that it has been shown in mice that the KLs have a synergistic effect when combined together: the effect of kavain or DHM when consumed with broad spectrum kava extract is stronger (and possibly different) than the effect of pure kavain or DHM by themselves. So because of that, it could be really hard to tease out the effect of the individual KLs.
