So in an effort to gear up my lab stuff, I recently bought a cheap peristaltic pump on ebay to help extract xylindein faster. Relying on gravity sure works, but it’s damn slow. So I filled up a funnel with xylindein-stained sawdust, connected the output to the pump, set the other end of the pump above the funnel for a closed-loop circuit of sorts, dropped enough acetone to soak all the sawdust, and fired the pump for a few minutes. Wow, I gotta tell you, this modus operandi is waay faster than the “wait for it” approach. In a matter of minutes, the acetone was saturated with xylindein, so much so that I had to pump it out into a vial and add fresh acetone to the funnel to continue extracting the pigment. Despite that, the sawdust still remains very green, and it will be good to go for another cycle after it has been very finely ground. I don’t have a proper mortar and pestle at the moment, so that will wait.
So there you have it, a better view of what the color of the stains made by Chlorociboria look like in the raw.
Next up: put a few drops of it into an AFM, a few other drops into a transmission spectrometer, and make science with it \m/
Hope you enjoy :) Cheers!
