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
Hosta plantaginea was a traditional Chinese medicinal plants used to treat inflammatory and painful diseases with partial scientific validation. Solvent extractions followed by repeated chromatographic purification of the H. plantaginea flowers led to the isolation of one new flavonoid glycoside,
Two new phenolic glucosides, hostaflavanone A (1) and anti-1-phenylpropane-1,2-diol-2-O-β-d-glucopyranoside (2), together with six known compounds, anti-1-phenylpropane-1,2-diol (3), phenethyl-O-β-d-glucopyranoside (4), phenethanol-β-d-gentiobioside (5), phenethyl-O-rutinoside (6), (1S,
Flowers of Hosta plantaginea have been used for the treatment of inflammation-related diseases in traditional Chinese medicine with limited scientific validation. In the present work, we reported one new rare methyl-flavonoid, plantanone D (1) and one known compound 4-hydroxybenzoic
Cold temperatures are a major source of stress for plants and negatively impact crop yield. A possible way to protect plants is to treat them with antifreeze proteins (AFPs). Here, we investigated whether fish AFPs can shield the rare ornamental species Hosta capitata from low-temperature
Ethnopharmacological relevance: The genus Hosta (Liliaceae family) represents an interesting source of natural bio-constituents, and the 50 species of this genus are widespread in the world. Five species have been used as traditional East
