An unusual cytostatic (PS ED504 μg/ml) lignan ester has been isolated from the Central American tree Phyllanthus acuminatus and designated phyllanthostatin A {1}. Separation of an MeOH extract of the root by size exclusion chromatography, high speed counter-current distribution, and semipreparative hplc afforded glycoside 1 in 0.007% yield. In solution, phyllanthostatin A was slowly transformed into justicidin B [4]. The structure of lignan glycoside 1 was determined by hrfabms and 2D-nmr spectroscopy.
