As one of the serial studies on the specific and indigenous plants of Mt. Chiri the constituents of aerial part from filipendula formosa (Rosaceae) were investigated. From of the MeOH extract, five flavonol glycosides, kaempferol-3-O-$eta$-D-galactopyranoside, querecetin-3-O-$eta$-D-galactopyranoside, quercetin-3-O-$alpha$-Lrhamopyranosyl (1 6)-$eta$-D-galactopyranoside, kaempferol-3-O-$alpha$-L-rhamnopyranosyl (1 6)-$eta$-D-galactopyranoside and quercetin-7-O-$eta$-D-glucopyranosy-3-O-$eta$-D-galactopyranoside were isolated by column chromatographic separation using Amberlite XAD-2 and Sephadex LH-20, and identified physicochemical evidences (IR, FAB-Mass, $^1H,{;}^{13}C-NMR$).
