Two new chromone glycosides from Drynaria fortunei

Two new chromone glycosides, drynachromoside (1), drynachromoside (2) were extracted from the dry rhizomes of Drynaria fortunei by means of bioactive-screening. Compound 1 exhibited the biochemical effects on the proliferation of MC3T3-E1 cells, while Compound 2 showed inhibitory effects against MC3T3-E1 cells.99
