Abstract
Phytochemical investigation of the stem bark of Zanthoxylum armatum led to the isolation of three phytoconstituents characterized as 1-linoleo-2,3-diolein (1), alpha-amyrin acetate (2), and armatonaphthyl arabinoside (3), which were elucidated using spectroscopic and chromatographic analysis. Among the isolated compounds, armatonaphthyl arabinoside (3) is a new naphthyl glycoside.
