Hi Everyone,
I finally got a better result!!! From 50g Acacia Acuminata root bark (AARB), I managed to get 500mg.
Below is my process; please advise me if you know of anything that I could have done to increase my yield.
50g ACRB 200ml water + 60ml acetic acid
Pressure cooker on high pressure for 2 hours
Repeat x 3. The liquid was still quite dark on the third pull. I wonder if I should have done more.
I accidentally added the fuel at this point, but I'm lucky it still worked.
I added 100ml xylene.
Then I added
80g sodium hydroxide (NaOH) + 200ml water (Mixed this the night before so it was cool)
40g sodium chloride (NaCl) + 200ml water (Heated to saturate)
I swirled the container about six times in an hour.
Then pulled the fuel and put it in a bowl with a fan on it to evaporate overnight.
I did this again with another 100ml xylene, leaving it evaporating with a fan.
In the morning, I added 50ml heptane and heated the bowl in warm water to melt the goo.
Then, put in the freezer overnight.
In the morning, I could see this was my best yield yet. Later, when I dried it out, it worked out at 500mg.
I was stoked with the results, as my previous attempts were about 170mg, but I guess they could be better.
Any tips will be greatly appreciated.
Thanks!

. Ah yes it’s 1% so I guess it’s not bad at all
