Bioaccessibility of Polyphneols from Youngia denticulata, edible wile vegetable, during Simulated Digestion

Abstract

Youngia denticulata is one of family Compositae and a good source of polyphenols. Young stalks of Y. denticulate have been consumed as wild vegetables in Korea. Polyphneols have various biological and pharmacological functions, such as antioxidant, antimutagenic and anticarcinogenic acitivites. For this study, polyphenols of Y. denticulata were determined by HPLC-ESI/MS and monitored the stability and releases of polyphenols using simulated digestion model. The simulated digestion model in the mouth, stomach and small intestine was mimicked with an acidic or neutral condition, respectively. The composition of polyphenols was determine by HPLC analysis.
