Beilschmiedic Acids F and G, Further Endiandric Acid Derivatives from Beilschmiedia anacardioides.

Two new endiandric acid derivatives, beilschmiedic acid F () and beilschmiedic acid G (), together with three known constituents, beilschmiedic acid A, beilschmiedic acid C, and sitosterol 3- β--glucopyranoside, 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 () was also confirmed by X-ray crystallographic analysis. [ABSTRACT FROM AUTHOR]
