Abstract

Phytochemical investigation of the root of Beilschmiedia erythrophloia led to the isolation and structural elucidation of two new endiandric acid analogs, endiandric acids I and J (1 and 2, resp.), a new benzopyran, dehydrooligandrol methyl ether (3), and a new benzenoid, farnesylol (4), 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.
