Two new flavone glycosides, 3'-hydroxy-5, 7-dimethoxyflavone 4'-O-β-D-apiofuranoside (1), and 5, 7-dimethoxyflavone 4'-O-[β-D-apiofuranosyl(1→5)-β-D-glucopyranoside] (2) along with four known compounds, 4'-hydroxy-5, 7-dimethoxyflavone (3), 2, 6-dimethoxy-1, 4-benzoquinone (4), lupeol (5) and betulin (6) were isolated from the stem and roots of Strobilanthesformosanus. Their structures were elucidated on the basis of their spectroscopic evidence.
