Four new glycosides isolated from Gerbera delavayi Franch

). The structures of isolated compounds were elucidated by analysis of 1D and 2D NMR, HR-ESI-MS, acid hydrolysis, as well as comparing with the literature. The isolated compounds were examined the effects of nitric oxide (NO) production inhibition in lipopolysaccharide (LPS)-induced RAW264.7 macrophage cells, and Gerbelavinside C presented a certain inhibitory activity.
