Abstract

<jats:title>Abstract</jats:title><jats:p>Phytochemical investigation of the root of <jats:italic>Beilschmiedia erythrophloia</jats:italic> led to the isolation and structural elucidation of two new endiandric acid analogs, endiandric acids I and J (<jats:bold>1</jats:bold> and <jats:bold>2</jats:bold>, resp.), a new benzopyran, dehydrooligandrol methyl ether (<jats:bold>3</jats:bold>), and a new benzenoid, farnesylol (<jats:bold>4</jats:bold>), together with six known compounds. Their structures were established on the basis of extensive 1D‐ and 2D‐NMR analyses in combination with HR‐MS experiments.
