Hydroxyalk-(4Z)-enoic Acids and Volatile Components from the Seeds of Zanthoxylum armatum

Abstract

Nonpolar constituents of the hexane extract of the weds of Zanthoxylum armatum (Rutaceae) have been identified as 6-hydroxynonadec-(4Z)-enoic acid [1], 8-hydroxypen-tadec-(4Z)-enoic acid [2], 7-hydroxy-7-vinylhexadec-(4Z)-enoic aicd [3], and hexadec-(4Z)-enoic acid [4]. In addition, the essential oil has been found to contain mainly linalool (58-396), limonene (24-46%), and methyl cinnamate (8.92%), besides several minor constituents.
