I cooked the grinded rue seed several times reduced the liquid and did a hundred filtartions while that. After that I added sodium carbonate (washing soda) it changed colour from dark brown to yellow/greenish (it also smelled like fish) I put it in the fridge.

Now comes my problem I filtered it and there where nearly no solids at all. So I added a lot (like 200gr on 300ml) of sodium carbonate and now there are solids but I'm not shure if it's just undissolved sodium carbonate (There wasn't any further color change maybe slightly brighter)?

My plan is to filter this solids out and continue with the process but I won't discard the liquid. Instead I will also try to salt the liquid. Any advice if they could be the right solids or why there haven't been solids in the first place?

Maybe you didnt add enough sodium carb to begin with. Maybe you filtered too quick before solids appeared?

In any case, your alkaloids are probably in the solids there, together with excess sodium carbonate.. Just put that, together with the stuff that precipitated before, and redissolve in acidic solution. Notice a lot of the acid will be just to neutralize the sodium carbonate, so if you add vinegar, it will start foaming, and keep foaming as you add and mix, untill all the sodium carb is neutralized and then the pH starts being acidic. Once you have it in acidic solution, filter and saturate with salt

If you alternate salt precipitation with base precipitation, whenever you redissolve the salt, you just need some hot water, no need for acid, so this is good because when you precipitate with base, you dont waste a lot of base to neutralize the acid..

And yeah dont throw anything away until youre finished.
