Abstract

Two new compounds, II and III, were isolated, together with 4-hydroxynicotinamide, from the fronds of both Arachniodes nigrospinosa and A. festina. The structures of II and III were elucidated as (E)-1-(2,3,4,6-tetramethoxyphenyl)but-2-en-1-one and (E)-1-(2,3,4,6-tetramethoxyphenyl)pent-2-en-1-one, respectively. Ryomenin (I) was isolated from the fronds of A. mutica.
