Hey all! Firstly, I apologise if this was posted in the wrong area; please move it if so!
I've been doing some tests on local Phalaris and Acacia (sophorae and pycnantha as far as my own ID takes me) to get an idea of alkaloid content. Just small runs for each, no washes. Most recently was on 100g shredded Pycnantha bark (sustainably sourced); 2x 500ml boils in ph3 water (vinegar as acid), combined and reduced to 500ml, basified with Sodium Hydroxide to a ph of roughly 13 (ph meter only reads to 11, but naoh was added incrementally to mathematically equal 13), and then pulled with warm Diggers Shellite while solution was still warm. 2 pulls of 200ml were used, evapped down to 150-200ml in front of a warm fan.
For all of my extraction attempts using Shellite, the solvent has never turned cloudy. Not when blown on, not when cooled or heated...and logically, I think, no crystals precipitate in the freezer. the Phalaris extract left a tiny amount of translucent goo behind on full evaporation. Could have been water...definitely not active, at that dose at least, and no indole smell. But (especially with Acacia) should I not have extracted SOME tannins at least, even if no desirable alks are presen
I have done my research but find only posts dating years back, and one report that the formula was changed... So my question, mostly, is this; is Diggers brand Shellite still a viable solvent for our uses? If so, the problem lies in my extraction technique...
Thanks in advance to any advice or input! Cheers!
