- DIRECT METHOD AND REAGENT KITS FOR FATTY ACID ESTER SYNTHESIS
-
Provided are efficient, cost-effective and water tolerant methods (e.g., single-vial methods) for preparing fatty acid esters from organic matter, comprising: obtaining organic matter comprising at least one fat substituent, contacting the organic matter in a reaction mixture with a basic solution under conditions suitable to provide for hydrolytic release of monomeric fatty acids from the at least one fat substituent to provide a base-treated reaction mixture, and esterifying the monomeric fatty acids of the base-treated reaction mixture by acidification of the reaction mixture and treating in the presence of an organic alcohol to provide fatty acid esters. The methods optionally further comprise, prior to esterifying, neutralizing the base-treated reaction mixture to provide for neutralized fatty acids, separating the neutralized fatty acids from the neutralized reaction mixture, and dissolving the separated fatty acids in the esterification reaction mixture. Also provided are related methods and kits for fat analysis.

- IRISTECTORENES A AND C-G, MONOCYCLIC TRITERPENE ESTERS FROM IRIS TECTORUM
-
Six new triterpene esters, iristectorenes A and C-G, along with one known one have been found in the seeds of Iris tectorum.On the basis of spectroscopic methods and chemical evidence, the esters were established to be 3--2,3-dimethyl-6-(1-methyl-2-oxoethylidene)cyclohexyl>propyl> (Z)-9-tetradecanoate, (Z)-11-hexadecanoate, (Z,Z)-9,12-octadecadienoate, hexadecanoate, (Z)-11-octadecenoate and octadecanoate, respectively.
