Cellular antioxidant activity and Caco-2 cell uptake characteristics of flavone extracts fromLabisia pumila

Summary The structures of two extracts of flavone , obtained from the stem (L40) and leaf (S40) of Labisia pumila (LP), were identified through UHPLC‐MS/MS analysis. An 2,2′‐azobis[2‐methylpropionamidine] dihydrochloride (AAPH)‐induced hemolysis model was used and the results indicate the protective effects of flavone extracts on erythrocytes against AAPH‐induced oxidative stress, in which L40 treatment performed the better.
