LABORATORY REPORT ON QUANTIFICATION OF ANACARDIC ACIDS FROM PISTACHIO HULLS
Article in Press
Pistachio hull contains Anacardic acids. It is a salicylic acid with a side chain either saturated or unsaturated. This work focused on the efficient extraction solvent for Anacardic acid. Six aliquots were weighed and extracted with hexane, ethyl acetate, and mixture of H2O/MeOH/HCl. Hexane was the most efficient solvent due to its ability to dissolve the Anacardic acids. Only one Anacardic acid standard was used to...
