Sesamin Extraction

have you done no research since last year http://cr4.globalspec.com/thread/31926

if the answer isn't good enough, you should say something. Explain. Discuss. Others may benefit from your insights. Debate. State your position and your problem, other than the obvious problem, that you are incapable of using a search engine to find your answer. I'm assuming that you have an abundance of sesame but little expertise. So I'll try to help again.

a quick google of "sesamin extraction" shows that the method will be found in this article you can buy for a few bucks http://www.springerlink.com/content/rn8487266263711j/

or read this patent, or find the person and license his method if you like it

Dear artsmith, Most of your comments are true. I came across springerlink ,but afraid of its credibility as I am not aware of them but now after your suggestion had decided to try them.Since an illetrate in chemistry I feel difficult to understand the procedures.So I am slow in proceeding.But now I have artsmith to help me out of hurdels! Regards abimu

The journals at springerlink are peer-reviewed science - rest assured, it doesn't get any better than that. It is quite an old article - 1964 - but the abstract says it covers the necessary ground including extraction methods and commercial preparations.

What sort of product are you hoping to produce?

abimu, I had another look for you, because if you are chemically illiterate you may be wasting your money on a journal article that you cannot read. To extract sesamin from sesame oil, you have to use chemical methods afaik. So you need to understand something about the chemistry, which I will try to explain.

Sesamin and sesamolin are furofuran lignans - that's a chemical description. They are found in sesame oil - about 0.5 - 1 %. They are soluble in organic solvents - generally speaking, nasty poisonous stuff. Like petroleum ether, which is used to extract high purity sesamin by HPLC as in this article here. http://www3.interscience.wiley.com/journal/119930496/abstract?CRETRY=1&SRETRY=0

Other sources also mention HPLC as the method of choice for sesamin extraction. HPLC equipment is expensive, and you would need chemical expertise to use it. If pure sesamin is the product you want to produce, try searching for "preparative HPLC equipment". You will also need training to use it. You will also want to use HPLC to test for your product purity, so you can offer a guarantee, like your competitors do.

I looked at two commercial posts for sesamin product, that give solubility information for their product.

"Sesamin is soluble in organic solvents such as ethanol, DMSO, and dimethyl
formamide. The solubility of sesamin in these solvents is 0.5, 12, and 33 mg/ml, respectively." http://www.pppindia.com/bb/msgs/2397.html

Another commercial sesamin producer says "Freely soluble in chloroform-benzene-acetic acid and acetone". http://www.bikudo.com/buy/details/552203/sesamin_sesame_seed_lignan.html

If you contact these commercial ventures, you can also find out what price they are getting for the product, and reckon how much you could earn by getting into this business, after your costs.

If the HPLC chemistry is out of reach, but you still want to make a product from sesame, there are some other possibilities without going to the "pure sesamin".

There is a free article here, about an insecticidal product made with sesame oil and some essential oils. http://www.bioone.org/doi/abs/10.1603/029.102.0140?journalCode=ecen

There are a few articles involving sesamin, available to read free at BioOne by this search http://www.bioone.org/action/doSearch?fulltext=sesamin&x=6&y=6

This abstract talks about an ethanol extract product - not pure sesamin by a long shot but still having some value as a health product.

I didn't bother to check all the references you provided, but I'd say this is not only a good answer, but a demonstration of patience.
