Antitumor constituents from Alternanthera philoxeroides

Abstract

Two new compounds, alternanthin B (1) and N-trans-feruloyl-3,5-dimethoxytyramine (2), along with four known compounds (3-6) were isolated from the aerial parts of Alternanthera philoxeroides. Their structures were elucidated on the basis of spectroscopic methods. The antitumor activity of the isolated compounds was also evaluated.
