We describe here a method using HPLC for the simultaneous determination of albiflorin, paeoniflorin, glycyrrhizin and six flavanone glycosides (liquiritin, liquiritin apioside, naringin, neohesperidin, hesperidin and narirutin) in the Kampo medicines, Shigyaku-san and Haino-san. All nine components were separated in less than 40 min by linear gradient elution using a mobile phase containing aqu...

Antibacterial and antifungal activity of ethanolic extract of grapefruit (Citrus paradisi Macf., Rutaceae) seed and pulp was examined against 20 bacterial and 10 yeast strains. The level of antimicrobial effects was established using an in vitro agar assay and standard broth dilution susceptibility test. The contents of 3.92% of total polyphenols and 0.11% of flavonoids were determined spectrom...

A ultraperformance liquid chromatography (UPLC)-photodiode array (PDA) detection method was established for the simultaneous determination of seven constituents in Fructus aurantii-Magnolia bark decoction: naringin, hesperidin, neohesperidin, narirutin, meranzin hydrate, honokiol and magnolol. These were separated in <17 min using a C18 column with gradient elution using (a) acetonitrile, (b) w...

Abstract This study assessed the protective effect of citrus flavanone, naringin (Nar), and its nanoformulation against di(2-ethylhexyl)phthalate (DEHP) toxicity in albino rats. Keeping green nanotechnology as cornerstone, nanoparticles Nar were synthesized characterized using electron microscopy (transmission scanning microscopy), particle size distribution, Fourier transform infrared spectros...
