Concentrates under a UV light.

I was over at a friends place and he had recently purchased a flashlight w/ a UV mode. Inevitably we shined the UV light on our oils and discovered a surprising difference between ours.

His is the top, pinkish one and was purchased from a local dispensary. It's mid-shelf price wise and says it was extracted with n-butane. Mine is the bottom, blueish one and was extracted yesterday with a QWET method. Considering taste, there's not a major difference between the two, though I'd say the blue one is slightly smoother.

I think the red color is from chlorophyll: http://antoine.frostburg.edu/chem/senese/101/consumer/faq/what-are-fluorescent-compounds.shtml

The blue is, I believe, associated with chlorophyll breakdown: http://www.sciencedaily.com/releases/2008/10/081020093454.htm

The oil I made was dewaxed in the freezer for 24 hrs so this might be proof of that working. However this is just speculation so I'd love to hear some input from some more chemistry minded members.

Very interesting ! I too would like to hear more about this, as well as if it's use and results can be utilized in determining anything relevant.

Thanks for sharing and leading off a possibly useful means of 'something' (?) :science:

I dont believe dewaxing effects chlorophyll in concentrates. Just wax lipids and fats. It would even make sence to me that if everything else besides the dewaxing was identically performed, there would be a higher content percent of chlorophyll due to less wax lipids and fats to balance the ratio.

I would love to hear what someone smarter than me has to say about it though.

Very interesting. I remember somewhere saying you can use the sunlight to breakdown the chlorophyl before the purging of a qwet/qwiso. So I think you may be on something practical. I thought about adding a uv light for the 2nd washes' purge that comes greenier.

Waiting for the schooled people to add in :)

I would love to see a comparison shot of these concentrates under normal lighting.

Don't have a comparison pic per se, but these shots will give an idea of the color:
Pink oil (before it was flattened):

Blue oil:

Not the greatest pics (especially the blue one), but these should give an idea of color. In normal lighting, the color is very similar, but the blue one is a shade or two lighter. It is also snap-and-pull, compared to the brittle shatter of the pink one.

Ya, too bad it wasn't a side x side to better compare with the same ambient light, surface, and background.... but, thanks for sharing regardless :tup:

ps: That 1st one (PINK), has me:mmmm: ! :peace:

The colors you are seeing have to do with the cannabiniods present the pink one is high in THC, not sure why the other is blue very strange.

My first couple of ethanol washes I performed my soak times where very long by todays standards and my ethanol would be very green to say the least.
To burn off the chlorophyl I would leave my clear glass jug in bright sunshine until the greens disappeared and the end result was a nice amber colour.
Thanks to GW at skunkpharm for his willingness to share his knowledge.

My google-fu paid off and I think I found the answer. And straight from Mr. Skunkpharm himself:
https://www.icmag.com/ic/showpost.php?p=5592190&postcount=3

We use a 3200 angstrom unit NDT blacklight to test for mold and residual solvent. They are normally used for fluorescent penetrant and magnetic partical inspection.

Mold and aflatoxins glow light green and solvent glows light blue. Other things glow too, with different hues. Plant waxes for instance glow, and act as a beacon for animals and insects that feed on the fruit they cover.

So going by that, the pink one is fully purged and waxy and the other one is less waxy but may have some residual solvent left.

I'm kind of surprised I can't find more info on this, seems like it would be a great tool for amateur extractors who don't have access to testing as well as consumers.

Wow can't believe I couldn't find that. I searched icmag with a bunch of UV related keywords and that thread never showed. I guess that's why you use google.

Anyways, I'm not sure if the answer is a simple as that. I asked the same thing on icmag a few days ago and GW responded with pretty much the same response, except this time he specified that it's petroleum solvents that "phosphoresce blue under UV"

Ethanol isn't a petroleum distillate so I'm not sure if it would still phosphoresce blue. It's possible it's just the reflection of the UV light. Every thing I've read online so far that concerns ethanol and UV lights, is just using the ethanol as a carrier solvent to allow a substance greater phosphorescence.

http://www.marietta.edu/~biol/field_station/field_notes/glow.html:
"We also found out that the ethanol in which we stored the scorpions would gradually become fluorescent itself, presumably as the beta-carboline leached out. Interestingly, just about any arthropod in our collection will leach a fluorescent material into the ethanol over time. Shine a UV light on our vials and they all glow a ghostly green."

http://antoine.frostburg.edu/chem/senese/101/consumer/faq/what-are-fluorescent-compounds.shtml:
"Chlorophyll fluoresces with a blood red color. Grind spinach or swiss chard with ethanol and filter the resulting chlorophyll extract. Bright white light can be used to drive the fluorescence. Place the extract in a petri dish on top of an overhead projector lamp in a darkened room to get the full effect."
