The title of this thread says it all. The purpose here is to establish average yields reported by people in the community from mimosa hostilis root bark sourced from different geographic locations. Ideally, extractions should be done side by side in order to minimize fluctuations in yield as a result of variations in procedures. If extractions are not done side by side, please indicate it and present any variations you are aware of.

At this moment in time, the most common locales appear to be Mexico and Brazil. However, if you have bark sourced from a more specific region of these countries, or from other countries please feel free to share your results. PLEASE DO NOT POST ANY VENDOR NAMES IN THIS THREAD. Thanks.

Texture
Brazilian:
Naphtha freeze precipped: Crystalline
Naphtha evaporated: Clay-like, crushed to chunky powder
Xylene evaporated: Soft clay, longer to dry, crushed to chunky powder

Mexican:
Naphtha freeze precipped: Crystalline
Naphtha evaporated: Clay-like, crushed to chunky powder
Xylene evaporated: Hard clay, crushed to chunky powder

Yield after recrystallization:
Brazilian:
Mexican:

Extraction procedure:
For both types of bark...

1) 454g of bark was split into 2 half-gallon mason jars and the jars were filled with acidified water.
2) Jars were pressure cooked at 15 psi for one hour.
3) Liquid was poured off and reduced. More water was added.
4) Steps 2 and 3 were repeated 4 times.
5) Acidified MHRB solution was poured into a jug and based.
6) 75ml of naphtha was added and the jug was agitated.
7) Naphtha was pulled and collected in an evaporation dish which was left out. Crystallization was visible.
8 ) Steps 6 and 7 were repeated 4 times.
9) The evaporation dish was sealed and put in the freezer.
10) 75ml of xylene was added to the jug and agitated.
11) Xylene was pulled and placed in a jar.
12) Steps 10 and 11 were repeated.
13) Naphtha evaporation dish was pulled out of the freezer, crystals were collected and excess naphtha was poured off and evaporated.
14) Xylene was evaporated, then manually re-x'd

Awesome Snozz thank you!

very cool, thanks for this. nice yield btw!

Thanks!

It'd be nice if we could get more people to chime in on this. I think the two other mentions I've seen of comparing yields from different locales have indicated a slightly higher yield from Mexican as well.

Interestingly enough, this would back the claim that a certain vendor used to have on their site stating, "The Mexican bark is as good if not better quality...than the Brazilian." More results should potentially help point solidly one way or the other.

Good work Snozz! The difference although measurable is not huge. I would not mind doing a comparison, but I have only the Brazilian bark on hand. I don't plan on purchasing any bark for a long time, and you know why.

thanks snozz, the nexus appreciates!!

This is a good thread!

A now defunct UK vendor used to stock Mexican bark and that stuff gave consistently larger yields via BLAB when compared to MHRB from a franchise of Ad3nium.IIRC, a drawn-out BLAB done over the course of about 10 days yielded a whopping 2.4ish% on the Mexican bark.

Im speculating here, but has anyone found that the time of year that the bark is acquired has a discernible effect on the yield?Im aware that the time one gets the bark in the hand may only be loosely used to determine the time it was harvested.

Recently had a run in with Brazil and was not happy at all compared to the Mex. I was very surprised at the Mex. It kept giving and giving, in short amounts of time in the freezer too.

that right there sums up my experience... & it makes no sense, at least to me... i got comparable yields, with the Mex coming up a little better each time... but the time in the freezer, amazing differences... with the Mexican, i was usually pulling my jars in about 12 hours (i have a very cold freezer)... with the Brazilian, i'm requiring 2 days in the same freezer to precip out all the spice... i've checked the temp on the freezer, nothing has changed... strange...

Ok, so I used CYB's Hybrid Salt tek on Brazilian & Mexican mimosa.
Yields were comparable, within a few 100mg of each other. I do get SUPER WHITE from the brazil and slightly yellowish from the mexican. Of course the variables of climate, age of root taken and overall maturity of the plant can't be specified, but I noticed that THUS FAR the mexican has been WEAKER in potency compared to the brazilian. The previous times I purchased, I had no idea what was extracted, nor how, just that it was DMT. Varying in qualities and presentation, all of them have had more "kick" than this mexican that I've just extracted. More testing needs to be done and some other subjects to take part and give feedback, but I'm wondering " Has anyone else noticed potency differences in other species of plants?"

Thanks to All
