In Strike's book "Sources", he mentions that betel leaf oil contains from 6.45 to 45.34% safrole. I feel that this would make a good source for safrole, because even though it's a little expensive, it's not watched and most essential oil companies sell it.
Here's the fucking problem: Betel leaf oil contains many other compounds, and I don't know how hard of a task it would be to separate the yummy safrole from them. Here's a list of chems you may find in this essential oil:
safrole
a-pinene
b-pinene
1,8-cineole
camphene
p-cymene
methyl chavicol
a-terpineol
a-terpinyl acetate
eugenol
methyl eugenol
b-caryophyliene
(e)-anethole
I think that alot of this shit can be removed by washing it with 3-5% NaOH, dH2O/acetic acid, dH2O, then heating it to 120*C for about an hour. After that, I think the biggest pain in the ass will be removal of the anethole. Without a vacuum pump, how can this be removed? Safrole freezes at
-14*C; what's anethole's freezing point? Could it be boiled off under normal pressure, without destroying the safrole?
The licorice plant(glycyrrhiza glabra l.)? (clycycrrhizia lepidata)? smells like sassy oil, but it also stinks of fennel, so I'm guessing that it contains anethole. Here's something I know it contains:
"Glycyrrhizin breaks down to glycyrrhizic or glycyrrhetinic acid; glycyrrhizin is an anti-inflammatory and inhibits the breakdown of the cortisol produced by the body." ->

. What else does this plant contain?
It would be a fucking blessing if many companies in the U.S. sold brown camphor, but all the ones I know of only sell useless white camphor. If anyone knows of a foreign or U.S. source, could you PM me with the url? Peace and happy cooking to all bees!
