Abstract

Phytochemical investigation of the flowers of Hosta plantaginea led to isolate of one new flavonoid glycoside,plantanone C( 1) by silica gel,Sephadex LH-20,and RP-HPLC column chromatographies. Its structure was extensively determined on basis of HR-ESI-MS and NMR spectroscopic data. Compound 1 exhibited moderate antioxidant activity against DPPH radical scavenging activity,with an IC50 value of 240. 2 μmol·L~(-1).

Keywords: Hosta plantaginea flowers; Mongolian medicine; antioxidant activity; plantanone C.
