Hi hoping sombody on here might have some ideas, I'm looking to make an extract rich in communic acid from Juniper (Juniperus communis) which is a
coniferous tree which contains this Diterpenoid. It is not necessary to isolate and purify the communic acid just to extract it. I can get Juniper
leaf, berries or essential oil as a starting point. Anyone know what part of the tree this diterpenoid would be found in highest concentration and
what solvents would be best to extract it?

You probably have seen this already: http://www.mdpi.com/1420-3049/17/2/1448
Are you sure you can extract a reasonably pure compound using just a solvent? I can't find references for that. Try to find with the oil supplier how
much communic acids there is in their product. Without acid/base workup or long, thick and tedious column chromatography I doubt you'll be able to
make a relevant extraction from an essential oil.

That's too broad a generalization. As an example oil of bitter almond is mostly benzaldehyde. Oil of wintergreen is over 95% Me-salicylate. Whether
isolating a compound from an oil source is relatively easy or difficult depends on many factors. A. Shulgin predicated a series of phenylethylamines
on their essential sources. Celery oil, I believe, was among them. Here's a link to a paper on communic acids.

Pure communic acid is a solid so not sure it would exist in the essential oil. A solvent extract of leaf,berry or bark would contain it but not sure
what part of the tree these diterpenoids are in highest concentration. I can easily get juniper berry's or juniper leaf.
