Did a short path run on some distillate that was chromatography tails (from THC remediation), column was c18 reverse phase with methanol water solvent system. The oil was about 55% CBD, 15% THC, before the short path. Sadly I do not have testing from the starting material. Expected to yield around 580g from a kilo. Ended up collecting around 800g of some good looking CBD distillate. The last 115 grams were collected as the tails fraction although there was no noticeable visual difference between it and main body. Ran on a custom 2L full bore setup, 190C-200c mantle temp, 10 microns for main body/tails, vapor temp 180-195c. Used exactly 1 kilo of starting material. After testing, here’s the results:
Total Cannabinoids- 80%
Leftover gunk in the boiling flask (about 75ml):
Total Cannabinoids- 62%
My question is, if you have 70% cannabinoid disty, what is the other 30%? Waxes? Fats? Has anyone done a comprehensive analysis of this? I’ll be doing one shortly and will post results. Id like to know if it is one compound in particular or a variety. It would have to have similar polarity to CBD considering it came out of an interchem420 chromatography machine so I’m more inclined to think it’s one compound. Anyone know a good NMR connect?
