Does acacia auriculiformis (earleaf acacia) contain extractable quantity of 5-meo-dmt??
Internet said it contains 5-meo-dmt
Tried before by anyone??

I don't think anyone has confirmed that, or provided evidence of the claim. Lots of things like that get claimed on the net, with no useful source to back it up, or a reference that turns out to say nothing of the sort. It's worth a try though!
