RESUMEN
Two new arylnaphthalene lignan glycosides, named reticulatusides A (1) and B (2), together with eight known compounds were isolated from the 95% EtOH extract of the whole plant of Phyllanthus reticulatus. The structures of the new compounds were elucidated by spectroscopic methods.

Three hydroxylated triterpene alcohol ferulates, (24S)-cycloart-25-ene-3 beta,24-diol-3 beta-trans-ferulate (1), (24R)-cycloart-25-ene-3 beta,24-diol-3 beta-trans-ferulate (2), and cycloart-23Z-ene-3 beta,25-diol-3 beta-trans-ferulate (3), along with known compounds cycloartenol trans-ferulate (4) and 24-methylenecycloartanol trans-ferulate (5) were isolated from rice bran. Their structures were elucidated by means of chemical and spectroscopic analysis. Compounds 2-5 showed moderate cytotoxicity against MCF-7 cells.
