Botanical origin characterisation of tannins using infrared spectroscopy
Food Chemistry, 2018Different approaches to analysing the botanical origin of tannins have been proposed in the last fifteen years, but are generally time consuming and require the use of advanced instrumentation. This study aims to suggest an effective, easy, rapid and cheap method based on the acquisition of FT-IR spectra of 3g/L hydroalcoholic tannin solutions ...

Anti-HBV agents derived from botanical origin
Fitoterapia, 2013There are 350,000 hepatitis B virus (HBV) carriers all over the world. Chronic HBV infection is at a high risk of developing liver cirrhosis and hepatocelluar carcinoma (HCC), and heavily threatened people's health. Two kinds of drugs approved by FDA for anti-HBV therapy are immunomodulators (interferon α, pegylated-interferon α) and nucleos(t)ide ...

Botanical origin of Mei-gui Hua in Chinese markets
Journal of Natural Medicines, 2017The petals or buds of Rosa species have been used as an important Chinese crude drug called "Mei-gui Hua" and also an ingredient for herbal tea in China. The 15 flavonol glycosides in 34 commercially available "Mei-gui Hua" were quantitatively determined by UPLC, and the data were compared with those of known Rosa sp. belong to Cinnamomeae, Gallicanae,

Identification of Flavonoid Markers for the Botanical Origin of Eucalyptus Honey
Journal of Agricultural and Food Chemistry, 2000European Eucalyptus honeys showed a common and characteristic HPLC profile in which the flavonoids myricetin (3,5,7,3',4', 5'-hexahydroxyflavone), tricetin (5,7,3',4',5'-pentahydroxyflavone), quercetin (3,5,7,3',4'-pentahydroxyflavone), luteolin (5,7,3', 4'-tetrahydroxyflavone), and kaempferol (3,5,7, 4'-tetrahydroxyflavone) were identified.
