Finding limonene or alternatives?

[sauroman1]

Hello. It was found that it is better to use instead of naphtha a limonene as non polar solvent because it pulls well DMT but not hordenine and gramine (or leaves only trace amounts). As SWIM is working just with phalaris grass, this time p. brachytachys which may contain unwanted alkaloids he could extract safe DMT. Problem is it that it is hard to find selled limonene in his country and it is probably expensive? Sugestions in finding limonene or maybe existing alternative nonpolar solvents would help.
