✦ Synopsis

Two new endiandric acid derivatives, beilschmiedic acid F (1) and beilschmiedic acid G (2), together with three known constituents, beilschmiedic acid A, beilschmiedic acid C, and sitosterol 3-b-dglucopyranoside, were isolated from the stem bark of Beilschmiedia anacardioides. Their structures were elucidated mainly by using a combination of 1D-and 2D-NMR techniques. The structure and relative configuration of beilschmiedic acid G (2) was also confirmed by X-ray crystallographic analysis.
