Two new prenylated flavonoids, named scariosin (1) and isorhynchospermin (2) were isolated from the leaves of paracalyx scariosa together with kaempferol, quercetin, kaempferol 3-O- rutinoside and rutin. The structures of (1) and (2) were characterized as 8-C- prenyl- taxifolin 7,3'-dimethylether and 6-C-prenylquercetin 7,4'-dimethylether by their chemical and spectra data, respectively.
