Studies of the optically active compunds of anacardiaceae exudates. Vi. The exudate from Pentaspadon officinalis Holmes

Abstract

The oil from the wood of Pentaspadon officinalis Holmes (family Anacardiaceae) consists largely of 2-hydroxy-6-(heptadeca-cis-8',cis,-11'-dieny)benzoic acid. It is very similar to the oil from P. motleyi Hook. f. and does not contain optically active cyclohexenones of the type found in Campnosperma exudates.
