BACKGROUND
Many diseases are associated with oxidative stress caused by free radicals. The aim of the present study was to evaluate the antidiabetic, antioxidant and antiglycation properties of Eysenhardtia polystachya (EP) bark methanol-water extract.
METHODS
: The antioxidant capacities were
Antioxidant activity (AOA) assay-guided chemical analysis, using a rat pancreas homogenate model, of aerial parts from Eysenhardtia subcoriacea, led to isolation of the new compound subcoriacin (3-(2'-hydroxy-4',5'-methylendioxyphenyl)-6-(3''-hydroxymethyl-4''-hydroxybut-2''-enyl)-7-hydroxycoumarin)
The antioxidant activities of plant extracts from Eysenhardtia platycarpa, E. punctata, and E. subcoriacea (Fabaceae) species, used in Mexican traditional medicine for the treatment of diabetes complications, were analyzed in a rat pancreas homogenate model. Methanolic extracts of E. platycarpa, E.
From the methanolic extract of Eysenhardtia platycarpa (leaves), were isolated the prenylated flavanones: 5,7-dihydroxy-6-methyl-8-prenylflavanone (1), 5,7-dihydroxy-6-methyl-8-prenyl-4'-methoxy-flavanone (2), 5,7-dihydroxy-6-prenylflavanone (3), 5-dihydroxy-7-methoxy-6-prenylflavanone (4),
Eysenhardtia polystachya (EP) is an endemic Mexican plant that has been widely studied for its antidiabetic, antibacterial, and antioxidant properties. Several studies had reported the main components of EP, but their fluorescence properties had not been broadly studied. In a previous study we
