    easiest way to know whats what is once youve obtained your oil fraction is pour it in water, safrole sinks anethole floats


How reliable is that? The densities are pretty close to 1 (anethole is 0.998, safrole is 1.094, from wiki).

I guess if the water is pure and at <20c it should logically work :-\     pretty neat idea/method if you needed to seperate the two  8)

hey b6baddawg have you done this, how 'clean' is the separation?   did you fractionate the separated oils or assay them in any way ?   

sorrry for all the questions dawgmon but it's a neat idea that I imagine could be used for other 'combos' as well,  so the more quality data we can compile here the better  8)

no i never did it ~ like i said i couldnt import the illicium variety, they dont ship outside the US.

anethole does float after steam distillation though. seen it.
havnt seen safrole but id be pretty sure it sinks.  :P
separating the two if together i dont rightly know. never read anyone doing it.
heres the illicium in question, along with the other varietys and distribution (big and small maps) i doubt the exhaustive completeness of the site i linked, eg they can be found outside the areas in question.

http://plants.usda.gov/java/profile?symbol=ILLIC

i dont particularly trust botanical references too much, anyone whose had their head in a number of books will know why, lot of conflicting data. best way if you suspect a illicium may or not be the right one, is practical ;)
The exact same species of plant can differ drastically region to region in its oil makeup, guides are ok but by no means a holy grail to go by.

asarum is another whats widespread what some species have oils of interest, be hard to find enough to be practical. buuut, seeds are available from garden stores or online. theres misinformation about them too, so do homework.

well thats a start ;D

seriously though I do like the idea in general as it could well prove  its worth in time 8)

As for small bushes containing saffy in the US...idk but I do know that its probably more than you think..google the question and variations thereof "safrole containing plants/in the US" and poke around I think you'd be surprised ;)

Surely you know of the sassafras trees around  ???  and in many places down south I believe you have similar camphora cinnamomun infestations like we have here! :o (Yeah you heard me right "Infestation" ;D)
Quote
Introduced to the contiguous United States around 1875, Cinnamomum camphora has become naturalized in portions of the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, North Carolina, Texas, and South Carolina.[2] It has been declared a category I invasive species in Florida

 The problem/question really is firstly "do they contain viable amounts and percentages of oils for extraction? Secondly "what percentage of the oil is the desired compound?"  these babies do ;D

Go and get yourself a few (hundred ;D) kilos of rootbark and juicy shoots and come back and steam distill them, more than likely the oil (around 5% w/w) of which maybe 10% is safrole sometimes more sometimes less, it depends on lots of things (position of plant, time of year, part of plant taken etc)  fresh has yet to work out any better methods of working out what parts of the plant to take to  extract, and so he just relies on the smell of the plant matter and when chopping the bark.  It's usually pretty strong on growing plants.

Fresh uses a 'mini' mattock same shape as a big one but about the size of a tomahawk  with a handle 40cm long and a 'head' that's about 25cm end to end. 

 sharpen the flat end on the 'inner' (standing on it's handle like a 'T'  that is the bottom/lower edge) quite sharp and you have something that works like an adze and can carve off bark deep chunks with ease ;D 8) they're fuckin great and make gathering the bark easy ;)

They're BIG trees with big roots and they often grow in clumps   http://en.wikipedia.org/wiki/Camphor_Laurel

and of course  http://www.erowid.org/archive/rhodium/chemistry/safrolefaq.html   8)

definitely worth checkin out if you haven't :)

 Fractionating the oil obtained from steam distillation to obtain a pure product is virtually a given. 
Maybe with some of the higher safrole content oils, freezing the safrole to separate it from the oil can be done as safrole has a very low mp

Here's the little green shrub I think you were thinking of/looking for

  http://en.wikipedia.org/wiki/Illicium_parviflorum

   The essential oil derived from leaves and branches of cultivated Illicium parviflorum contains approximately 68% safrole, which is mostly responsible for the plant's pleasant aromatic odor of root beer (like Sassafras), or licorice and mint. Minor contributors to its aromaticity include linalool and methyleugenol

as I somehow didn't notice that bbaddawg had already suggested this ^^ ::)

How about distillation with water?

ummm . . . did you bother to read ANY of this thread baba?  ???

Where do you think  'steam comes from?'  :o

Surely the title of the thread 'gave it away'  no?  :)


bit of a brain fart baba :P  happens to everywasp ;)

next time at least have a look at the OP!  ::)

What he is talking about is not steam distillation its known as hydrodistillation and is a single pot but it will destroy many unstable volatiles due to excessive prolonged heating, however it works very well for Safrole distillation.

Sorry sedit but I must disagree here.  And far from  'just for the sake of it'  :o

 What he describes in that paper is precisely the SAME process' we're discussing here.  "hydrodistillation" = 'water distillation'

  using the steam from boiling water to 'carry over' the desired oils into another container for separation/extraction

 And using effectively the same 'style' apparatii  (including the holding 'baskets' or 'steamers' salat mentioned)

Exactly the same!  No more or less.

  How do you consider it 'different?'  If you can show me differently please do :D

There is mention of some methods not discussed here (maceration) but they're not suitable for our purposes

It is different.  You just can't see it.

Because in the basket there is no direct contact between the boiling water and the plant material. Only the steam comes in contact with the plant material however in hydro-distillation there is constant direct contact as the plant material is directly in the water at all times.

Hydro-distillation is much harsher on volatile oils then steam distilling.

hey been awhile since i last visited, but glad to see the discussion has progressed. i finally gathered enough money to buy a pressure cooker and hotplate, of which the hotplate has arrived and the pressure cooker will be arriving sometime next week.

not to nitpick, but hydrodistillation is the term used for all three of the water distillation methods.

1. water distillation- plant matter is in direct contact with the water (what sedit is describing). this method works best if the plant material is finely separated (powder). not recommended for water-soluble or high B.P oils.
2. water and steam distillation- plant matter is in the still with water, but suspended above so not in direct contact with water (fresh method). best method for herb and leafy materials, but not to say that roots or barks won't work here too.
3. steam distillation- plant matter in separate container with wet or superheated steam being added via a hose. best suited for roots and barks containing high B.P oils.

 found this book, The Essential Oils by Ernest Guenther, to have very valuable information on the subject. it is a six volume set, but only the first volume is free or at least i could only find the first volume free. heres a link to the book if anyones interested.

well in a week my experiments begin, til then be happy and call your mum and tell her you love her for giving you the gift of life

agreed about the nomenclature. traversing this site has been an "experience" to say the least when it comes to the names.

my old futbol coach told me about KISS, highly underrated acronym.

i will return when i have more related information to this thread.
