The phenolic acids of Pistachia vera

Add time:07/27/2019    Source:sciencedirect.com

The solvent extract of the outer green shell of the pistachio nut, Pistachia vera, was found to contain a mixture of phenolic acids. From their 1H and 13C NMR spectra and accurate mass measurement, their structures were established as 6-alkyl and cis 6-alkenylsalicylic acids. The approximate composition was found by GC and HPLC to be: (13:0) 46%, (13:1) 17.4%, (15:0) 10.3 %, (15:1) 7.3% and (17:1) 19.0%, anacardic acids. The double bond in the monoenoic acids was found by oxidative degradation to be at the 8-position. The predominantly C13 side-chain in the phenolic acids is novel.
