A new phenolic glycoside and cytotoxic constituents from Celosia argentea.

Abstract

A new phenolic glycoside, 4-O-β-D-apifuranosyl-(1→2)-β-D-glucopyranosyl-2-hydroxy-6-methoxyacetophenone (2) and 11 known compounds were isolated from the MeOH extract of the plant Celosia argentea. The structures of the compounds were elucidated on the basis of spectroscopic analysis and chemical methods. Among the isolated compounds, stigmasterol (10) showed moderate inhibitory activities against SGC-7901 and BEL-7404 cells.
