What yields are you guys getting from mhrb?

I've been getting great yields from my bark, a 40g mhrb extraction yielded .69g

After my first pull today I got another fantastic yield from 30g mhrb. In addition to all this (it's still wet) the solvent I poured off into a test tube amd 3/4" was filled with small white crystals that settled to the bottom.

What about you guys?

Doesn't really matter how much we're getting. It won't tell us anything. It all varies based on the bark quality (ranges from 0.5 to 2%, sometimes even 3%), as well as how thorough the tek is at extracting it (no tek is able to get 100% of the alkaloids).

Congrats on having bark with almost 2% alkaloid content!

not shure about MHRB but acacia bark is about 1 gram per 100 grams of bark..and its often more than that...

1,7 % of that white result,
in my still-a-little book that is a success.

Source?

I don't have time to do research for you if you want to know more, but even the Wiki has a quick mention about this:

https://wiki.dmt-nexus.m...ostilis#Alkaloid_content

"Root Bark contains DMT - 0.31% to 0.57% (Schultes 1977)
Inner root bark contains up to 2% active alkaloids (Extractions from DMT-Nexus and others)"

The wiki is not completely correct. Some lucky people get over 2% alkaloids. Hence the 0.5-3% range.

Basically: Root bark is in the ~0.5% range, and inner root bark (the nice, inner portion) is in the ~1-3% range.

Different suppliers have different ratios of inner to outer root bark, etc, and that is why bark quality matters.

All I'm saying is that I don't understand where you are getting 3% from. The sources you cite say up to 2%...but then you keep saying 3%.

I'm not asking you to do my research for me, I'm simply questioning where you are getting your numbers.

I think Samadues has it a little confused where I says 3% of the total alkaloids , meaning 0.04%of root bark is nmt !

Twelve pages of yields and it's a sticky

I thought it would be interesting to ask real people who do real extractions because in the end, they're the only ones who get to see their numbers.

It sounds like inner root bark is where it's at.

2-3% active alkaloids seems vague and dubious; no mention of what those active constituents are, their respective relative abundances, nor any sort of characterization/m.p. tests. Getting 1% high purity DMT from inner root bark is a stretch.

Nah I intentionally didn't include that line at all, since it's talking about something totally different. The line you are referring to said "3% of the total alkaloids (or 0.04% of rootbark) is NMT and 2-Methyl-1,2,3,4-Tetrahydro-Beta-Carboline" - in other words, 0.04% of the bark is the above two non-DMT alkaloids.

In case any newbie is confused by what I just said: Just ignore that line. It's about other alkaloids and has nothing to do with DMT.



That's a VERY good point. The people getting over 2% crystals probably pull with a bad solvent and get other alkaloids too, thus getting a "fake" weight padded by impurities.

People doing Heptane pulls will have less impurities and therefore less weight (the *real* DMT).


If I had energy to do more research I'd try to look up lab tests... I read something once which said that professional labs measured it in the 2-3% range and that the reason that people get 0.5-1.5% yields is because their teks simply aren't efficient enough to get 100% of the content.

I would be happy to hear a correction if this number is incorrect, since I don't want to misinform anyone.

Benzyme you wouldn't know of any references to DMT and DMT m.p. information and sources off the top of your head would you? Everything I found online bounced up and down and always showed a 20 degree mp range. I think that's completely unacceptable as a reference. I've seen some quotig 60-80C
And other unhelpful sources claiming 140+.

Most sources say DMT boils and then evaporates in the 60-80 range.

People have tried putting it in a test tube submerged in 100*C boiling water and it didn't cause any vaporization.

So perhaps the reason home-extracted DMT isn't evapping until well after 100*C is because it's impure and mixed with some plant oils that resist the heat a bit better?

I find this rather unlikely, as it appears that the yields reported by underground extractors generally exceed those presented in the literature. There's an article in issue two of The Nexian that presents one comparison, detailing a lab extraction where yield was well below 1% (Criminals and Researchers...).

burnt's analysis seems to indicate that there isn't much else in jungle spice aside from dmt and minor amounts of 2-mthbc and nmt, so I think the "bad solvent" claim also appears unsupported, at least initially. There may be some increased yield, but I think it is unlikely to be incredibly significant after multiple re-x (or a/b) cycles.

DMT´s boiling point is most definitely NOT 60-80. Shulgin commented on this in TIHKAL, it was an error from Merck Index. Unfortunately there doesn`t seem to be any publication with an accurate value of BP but from different experiments done in the Nexus plus theoretical calculations it definitely seems to be over 100c. Chemspider calculates it to be 332c, though that does seem very high (and would make me wonder how can people vaporize it with the volcano vaporizer which only goes to max 230c)

The varying in melting point is not a mistake or gross inaccuracy but rather related to the polymorphic properties of DMT:

http://www.sciencedirect...le/pii/S0026265X13000544

assuming there exist various isoforms of DMT, because supposedly the alpha and beta carbons are rotatable, the commonly depicted form (as shown on that site) has the higher m.p./b.p. range, because it is a more stable structure.

the other common (and apparently more prevalent form) is analogous to a cis-conformation (yes, I know there are no double-bonds in the ethyl-amino moiety), where the dimethylamino would be bent downward about the alpha carbon, and the amines would be in closer proximity.

I edited my above post, I had accidentally pasted wrong link, now it`s fixed. Polymorphism of DMT was shown in that publication, as well as it`s relation to DMT melting points.

I've tested a friend's sample with a Unimelt, and got 41-44C, corrected to +/- 1C.
from MHRB inner-bark, triple re-x with heptane.

his yield was somewhere between 0.3%-0.7%

Thanks for correcting the number.

I previously read an article where the number was high (2-3%), and I remember thinking "Huh... I guess our extractions are not efficient enough"... This number continued to be reinforced by seeing some people report 1.5-2.5% yields here and there.

Whatever I read, it's clear that it was wrong about its numbers. Perhaps it referred to total (including non-DMT) alkaloids.


What would you say is the average % range, as well as the most common yield size, of DMT from MHRB? That question also goes to endlessness and other long-time regulars.
