Rhyncosides A-F, phenolic constituents from the Chinese mangrove plant Bruguiera sexangula var. rhynchopetala.
Chemical investigation on the stem of a Chinese mangrove plant Bruguiera sexangula var. rhynchopetala (Rhizophoraceae) resulted in the isolation and characterization of four new phenolic glycosides rhyncosides A-D (1-4), and two new lignan derivatives namely rhyncosides E-F (5-6), along with twelve known phenolic constituents. Their structures were determined by extensive spectroscopic data analyses.
