this is the best i could get with 91% and dried, chopped, frozen popcorns. this is just running the ISO over the popcorns, not put in a mason jar, just poured right over.
Today im trying with 99%, right off the plant fresh, frozen, untrimmed, nugs.

i prefer using dried materials, with qwiso.
first i use alot less contact time. really seconds, i repour over the same material 2-3 times, but always seperate the last pull and the squeeze.

and if you do get green color just put the alch. in the sun or under an hid.

your two biggest problems are(imho)
contact time
and maybe not working fast enough??? if your alch. isnt super cold it will draw out water and other things that will make you oil dark and harsh.

You're close. Maybe the difference between 91% and 99%.

Maybe some room for tweaking too. Did you chill the Iso and buds first? How fine did you chop the bud?

Strong UV light before evaporating away the alcohol, will break down the light green chlorophyll tint, but will also destroy some cannabinoids. Probably not noticeably, with no more green hue than you have.

The real test is the taste. Unless it tastes bad, is harsh, or doesn't work well, why should we really care what color it is?

If you want gorgeous amber, it would be easier to start with a non polar solvent, but then you don't get some of the same floral undertones.

I only extract dried material with Iso, because of the issue with the water solubles.

I've done fresh frozen material with Iso, but it has a soapy taste, while Iso from dried material is floral and tasty.

The taste is initially amazing, but it gets a burnt taste kinda quick...
ISO and Buds were chilled for 24 hours, buds were chopped pretty well.
So the green will leave if i put in in the sun? then it will just be kinda black correct?
The color does not bug me at all, id just like to learn how to get it amber.
Thanks!

Sorry I didn't notice this first! I suspect your color is in the 91% Iso unless you chopped fine.

Looks like we are missing each other by one post. Hee, hee, hee..........

Try just breaking the nugs up by hand to about 1/4", and you will have less leaf margins bleeding cholorophyll.

Get some 99% instead of 91% and I suspect you may be there.

Are you vaporizing the oil, or are you burning it? Burned oil does develop a phenolic taste, because it is a phenol.

If you put the alcohol and oil solution in the sun, before evaporating it off, the UV will break any chlorophyll down into its components, which are not green. A bandaid, not a fix.

n-Butane or n-Hexane would be my two choices.

Will the Chlorophyll be "easier" to remove once its been broken down into its components?

This is a very successful scenario. I did it with ethanol 96% and was literally shocked by the purity of the extract.
Ethanol dissolves more slowly than isopropyl, the duration of pure extraction of fresh flowers in ethanol is a few minutes, even without freezing.
The key point is the juiciness of the material. Contrary to popular belief, juiciness and intact epithelium perfectly protect the chlorophyll from the solvent access to it.
Moreover, careful hydration of dry material also improves the quality of the extract.
This is the fastest of all the clean extraction methods. Amber in 15 minutes after removal from the bush.
