completely agree - have and will extract, but trying to find the right path based on this knowledge repo based on my stated goal/experience with the aforementioned. 
have so far failed to get this yellow 'dmt'. But having read a lot from this source, many others describe yellow and orange dmt in such a way that it would seem likely that other synergistic alkaloids in mhrb/acrb exist. 
current investigation will test xylene pulls on mhrb/acrb and with and without pyrolysis on inhalation.
