ephedrine via fermentation - it works! part 1 | Bookmark Reply | ||||||
We've all been there. It's 3AM, you've run out of bee fuel, and the guy who get's those cases of pills is nowhere to be found. You're thinking " gee, I wish I could make my own ephedrine. Life would bee so much easier! Well now you can. SYNTHESIS OF L-EPHEDRINE VIA FERMENTATION- PART 1 THE SYNTHESIS IS IN TWO PARTS: PART 1: FERMENTATION OF CARBOHYDRATES BY SACCHAROMYCES IN THE PRESENCE OF BENZALDEHYDE TO PRODUCE PHENYL-ACETYL-CARBINOL PART 2: REDUCTIVE AMINATION OF PHENYL-ACETYL CARBINOL TO PRODUCE L-EPHEDRINE WHAT COULD BE EASIER?? Part 1 1 kilo of blackstrap molasses is placed in a fermentation vessel and combined with 8 oz. of artificial almond extract. Two tablespoons of fleischmans Active dry yeast is added and vessel sealed with a simple airlock (bubbles gasses through water, allowing pressure to escape while preventing outside air from entering vessel. Available at homebrewing suppliers for around a buck-fitty.) fermentation is allowed to proceed in a cool, dry, dark place (ie. basement, closet, etc.) FOR 5-6 DAYS. IT IS CRUCIAL THAT NO WATER IS ADDED TO FERMENTATION MIXTURE!!! After fermentation is complete, the fermentation mixture is distilled, with the desired portion coming over between 75-85c. More coming soon........ obvioso. |

NO! The method you proposed WILL NOT work. The fermentation mixture MUST be ACTIVELY FERMENTING BEFORE YOU ADD THE BENZALDEHYDE. |

ok, so from what swij figures from reading the attached link of jacked's writeup and this current post that instead of adding the benzaldehyde right away that the mix is let to ferment for 10 hrs. then it's added and depending on how much benzaldehyde is added and how much yeast is also added the mix is then let to ferment accordingly(most likely 5-6 days)? this sound closer? "this could be an illusion but i might as well try..." |

That sounds better...Its just like making the ol' brewisky...The most activity is in the first 12-32 hours, (depending on temp). The first stage is the yeast doing all of its growing and multiplying. After that is actually when the fermentation takes place, (after about 24+ hrs). The fermentation only actually last about 5-9 days. (Once the food is gone, the cells go back into remission and fall to the bottom. Thats when its done). At least that is how it is in brewing beer...Wouldn't think much different here. --Why '77', You get "Eight" more!!!-- |

(1)The concentration of benzaldehyde in the sugar solution must NOT be to high that it poisons the yeast bacteria. (2)Benzaldehyde is not very soluble in water or sugar solutions. Patents & journals!! Another thing now to add to my list of,"things to do". |

With all due respect wiz-x: 1. Solubility is not really at issue. It is a (homogenous)mixture, not necessarily a solution. 2. When the yeast is introduced to carbs, it rather immediately begins to convert those carbs to alcohol. I can assure from personal experience that the yeast ARE actively fermenting with this level of benzaldehyde, from the gate. As for the other inquiries raised here: Yields are around 40% of the starting weight of molasses. This is not based on my own personal experience. However I have done quite a bit of research on this method, as well as a fair bit of experimentation. I have seen conclusive evidence of the efficacy of this procedure. In other words I have NO DOUBT that this works (hence the title of this post.) |

Notes on Ephedrine Synthesis ---------------------------------------- Actively fermenting yeast transforms benzaldehyde into L-phenylacetylcarbinol (L-PAC), which can be reuctively aminated to afford ephedrine or phenypropanolamine (depending on the amine used) ---------------------------------------- Author: Gazaliev, A. N.; Zhurinov, M. Zh.; Fazylov, S. D.; Balitskii, S. N. Reference: Chem.Nat.Compd.(Engl.Transl.), 25, 3, 1989, 261-271 Title: ISOLATION, ANALYSIS, AND SYNTHESIS OF EPHEDRINE AND ITS DERIVATIVES Abstract: A review is given of methods for the isolation, quantitative determination, and modification of the ephedrine alkaloids, and advances in this field of natural compound chemistry. ---------------------------------------- Title: The biosynthesis of ephedrine Abstract: It is shown by 13C nuclear magnetic resonance spectroscopy that the labelled C2 fragment of <2,3-13C2>pyruvic acid is transferred intact into the C-methyl group and the adjacent carbon atom of the Ephedra alkaloids, norephedrine, ephedrine, norpseudoephedrine, and pseudoephedrine, in growing plants of Ephedra gerardiana.This finding serves to identify pyruvate as the elusive precursor of the aliphatic C2 terminus of the skeleton of the alkaloids.In earlier experiments with 14C-labelled substrates, label from <3-14C>pyruvic acid was incorporated mainly, but not exclusively, into the C-methyl group of ephedrine, and label from <2-14C>pyruvate was incorporated similarly into the carbon atom adjacent to the C-methyl group.A C6-C1 unit related to benzaldehyde or benzoic acid has long been known to generate the benzylic fragment of the carbon skeleton of the Ephedra alkaloids.It is likely that the carbon skeleton of ephedrine is generated from pyruvate and either benzaldehyde or benzoic acid, by a reaction analogous to the formation of acetoin or diacetyl from pyruvate and acetaldehyde or acetic acid, respectively.Key words: biosynthesis of ephedrine, Ephedra alkaloids, 13C NMR spectra, ephedrine, biosynthesis of pyruvic acid, incorporation into ephedrine 13C NMR spectra.

X, 1937, (London) "A NOTE ON THE DETERMINATION OF THE ALKALOIDS OF EPHEDRA" by F.E.RYMILL AND C.A. MACDONALD, From Evans' Biological Institute, Runcorn Recieved 12th June, 1937 (From page 463) "...Shake frequently during five minutes 20 gm. in No. 40 powder with 200 mils of a mixture of 1 voluome of chloroform and 3 volumes of ether; add 10 mils of dilute solution of ammonia and 1 gm. of anhydrous sodium carbonate. Shake at frequent intervals for four hours and allow to stand overnight. Transfer to a percolator and continue the percolation, first with 100 mils of the ether-chloroform mixture, and then with ether, until the alkaloid is completely extracted; shake the combined percolates with successive portions of 40, 30, 20 and 20 mils of N/3 hydrochloric acid, to the combined and filtered acid extracts, add N/1 sodium hydroxide until the liquid is only slightly acid, then add 10 gm. anhydrous sodiumcarbonate and sufficient sodium chloride to saturate the liquid, and shake until dissolved. Extract the alkaline liquid with four successive portions of 60,50,50 and 30 mils of ether, and then with 25 mil portions of ether until the extraction of the alkaloid is complete (usually five shakings are sufficient). Allow the combined ether extracts to stand until clear, and decant through a filter; warm, warm, and pour off the ether from any crystals which may separate, evaporate to a volume of about 10 mils, and then allow the residual solvent to evaporate spontaneously. Dissolve the residue in an excess of N/10 sulphiric acid, add 20 mils of water, and titrate the excess acid with N/10 sodium hydroxide, using methyl red as indicator; each millilitre of N/10 sulphuric acid is equivalent to 0.01651 gm. of total alkaloids calculated as C10H15ON..." Method (from page 464) Ten grams of the herb in No. 40 powder is shaken up for five minutes with 200 mils of a mixture of 1 volume of chloroform and 3 volumes of ether. Subsequently 10 mils of 10 per cent solution of ammonia and 1 gm of anhydrous sodium carbonate are added, and the mixture shaken half-hourly for four hours, then allowed to stand overnight. Next morning the mixture is transferred to the percolator and percolation continued with 100 mils of the ether chloroform mixture and then with ether until the alkaloid is completely extracted. The combined percolates are shaken with successive quantities of 40, 30, 20 and 20 mils of N/3 hydrochloric acid and N/1 sodium hydroxide is added to the combined filterd acid extracts until nearly neutral. Ten gm. of anhydrous sodium carbonate is added and sufficient sodium chloride to saturate the solution. The alkaline liquid is extracted with 20,10,10 mils of chloroform followed by sucsessive 5 mil portions until the alkaloid is completely extracted. Three extractions are usually sufficient. The combined chloroform solutions are washed with 5 mils of brine, the brine being washed with 5 mils of chloroform which is added to the main bulk; 20 mils of N/10 hydrochloric acid is pippeted into the bulked chloroform in a separator, shaken and the chloroform run into a second separator, where it is washed with distilled water twice, the washings being added to the acid liquors in the separator. The combined acid liquors are titrated with N/10 sodium hydroxide to methyl red.

The solution is shaken under cooling with ice until all solids has dissolved. The walls of the beaker is rinsed from any residual crystals with 10 ml conc. H2SO4, the beaker is removed from the ice, and left to stand at 15 deg C for 15 minutes, whereupon the contents of the beaker is poured upon 200 grams of crushed ice in a 500 ml beaker, which also is cooled from the outside with an ice-bath. 300 ml of absolute ethanol is now added, whereby beautiful white crystal needles of (+)-Pseudoephedrine-O-sulfate ester precipitates. The crystals are filtered with suction in a small Buchner funnel, washed with a little cold water, and after air drying the yield is approximately 10g of (+)-Pseudoephedrine-O-sulfate ester. ---------------------------------------- If you care...

Re: ephedrine via fermentation - it works! part 1 | Bookmark Reply | ||||||
First off, everybee should give obvioso1 a fucking break. NO fucking bee has tried this reaction to my knowledge and once somebee like obvioso1 shows up with a synthesis that actually seems pretty credible when you think about it, everybee just flames him (weeeellll, not that bad but there was a lot of negativity regarding responses). Anyway, this cat has done a lot of reading lately and as far as this cat can tell, obvioso1's synthesis should work to some degree. Here's why: 1.) He used baker's yeast when everybee says he should have used brewer's yeast. Baker's yeast, however, was used in the original synthesis on which US Patent 1,956,950 is based. Yields are approximately 18% (molar). Regarding the above mentioned patent, everybee thinks the low amount of methylamine used in the reductive amination accounts for the low yields of final product (25-40ish something grams of crude ephedrine). Actually, the low yields are due to the low percentage of L-PAC that is in the crude extract to begin with (which is about 18%). 2. New methods use molasses as their source of dextrose sugar. So using blackstrap molasses is in all probability, rather good. 3. Artificial Almond extract (8 0z) contains approximately 10 or so grams of benzaldehye. The rest is alcohol and propylene glycol. For those interested, SWIM has informed me that water dilution of the extract followed by solvent extraction and evaporation yields the transparant colorless goods. 10 g of benzaldehyde is just about right for the proportions required by obvioso1's synthesis. 4.) According to the literature, the yeast CAN be added right from the get-go. Apparantly, the synthesis just takes a bit longer, as in the 5-6 days of which obvioso1 makes use. As for by-products, according to the literature, the only ones that seem to form as a result of this reaction are benzyl alcohol and benzoic acid. Obvioso1, please come back and share your results with us! |

Hmm... some thoughts from a homebrewer: 1) At homebrew shops, you can buy pure dextrose. Wouldn't that be more efficient than molasses? The concern I have is the greater amount of by-products in a molasses fermentation (in my experience there would be some), which would be harder to vacuum filter out. 2) For maximum efficiency I would agree that you ferment the yeast in dextrose and then, 4-8 hours later when fermentation is active, add the almond oil. Again, the concern would be purity (less chance of side bacteria mucking up your sugar); plus the fermentation will take over the almond oil quicker, I would think. But really it sounds like a good potential method. I'm curious what your results will be. :) (BTW I would almost think a typical brewer's yeast is *not* the way to go, I'm thinking that byproduct production for fermentation would be signifigantly less for baker's yeast. However, I'm only speculating here. Usage of a simple sugar like dextrose will help eliminate by-products no matter what, I guess; but many brewers yeasts are *known* for those funky esters that they ferment at various temperatures, so...) |

The use of a 5 gal platic bucket is acceptable, with some precautions: 1) DO NOT use bleach to sanitize the bucket. Use 7% tint (just a splash). The esters formed from bleach have ruined many a batches of beer in the past. Preferably use a 5 gal glass carboy (around $20 USD from brew suplier). 2) Beer fanatics highly discurage the use of corn sugar (dextrose) in any part of the fermentation process because a light alc taste. (Malt produces the alc the same, but its side products give the brew the flavor). Ill concure w/ the use of dextrose to help elliminate by products. 3) Cooler fermentation temp are also recommended to reduce the production of esters. (Lager are fermentated between 38-55 degree F, while ales are 65-80 deg F. You'll note the ales have a fruitier taste) Previous postings from yours truely ment not to bash the idea's posted here, for I too am completly for this.

Please do keep all posted on the process used and the out come so we may all learn from each other. ![]() --Why '77', You get "Eight" more!!!-- |

The bear also awaits with optimism, as he knew someone briefly in the past who spoke of this pathway. An illustrious member of a famous club, this fellow was. We were on "vacation" together in the 80's. During these long ago and brief conversations, it was emphasized to the bear that NATURAL ORGANIC molasses should be sought, not anything with a chance of chemical preservatives or flavor enhancements. For whatever that is worth. Natural yeast could be hindered by any traces of "chemical" preservatives, or flavorings. My experience with fungus cultures would tend to confirm this might bee true. At the time, unfortunately, the bear paid little attention to the details, as several "mythological" processes were discussed, including RP/I on a paint shaker (naw?, you're kidding?...yes! on a paint shaker!) and the bear was unwilling to write anything down, due to nosy hacks etc. So, please fill the dumb bear in when you can, Obvioso. supporting the constitutional right to arm bears |

At the rate at which the "farces of evil" (read as WOD) seem to be impeding the path for those of us who truly desire the freedoms that this cuntry supposedly was based upon offering I've recently thought that the best overall paths to cover one's proverbial ass with against possible future limitations of "needed precursors" would be a combination of... 1) Learning to effectively biosynth ephedrine/phenylpropanal stuffs. Thus bypassing the need to ever deal with adultered pill stocks/garbage again. 2) learning a viable electrohydrogenation technique while Pd is still relatively affordable and obtainable. Thus bypassing the need for any RP, Iodine and other such baking goods that are challenging to acquire. I could be wrong in these assumtions but it would be a good feeling to know that that one had become relatively self sufficient from the paths that the WOD seems so intent now on closing up entirely.

ChemoSabe, I agree with you with two additions which expand it a bit.. 1. Natural sources can be shown to be pretty facile in their employment to good ends as well, more to follow (I hope..) 2. In lieu of electro (which I really like...) straight pressure/Nickle catalyst hydrogenations should be perfected, as Ni is impossible to control, and with Al similarly available, why, Pd isn't necessary. I also like the fact that hydrogenations go to an endpoint where no more H2 is taken up: whereas electro is hard to get "just right", and under or overkook is the usual outcome. Also, you have to make an ester or other intermediary with electro, whereas all you gotta do is shake the hydrogenator. dwarfer |

Not exactly my language. but nothing on chemfinder nor google. For someone who was not born with a Sigma-Aldrich account this can get quite boring ya should know. ORGY |
