Three Weissella confusa and five Weissella cibaria strains were previously isolated from human faeces and their potential as probiotics was examined in this work. Resistance to low pHs (pH 2.0 and 3.0) and 0.3% bile salt were examined. Enzyme activities, susceptibilities to heat treatment and various antibiotics, and adhesion capacities to Caco-2 cells were(More)
BACKGROUND Since oxidative stress has been implicated in a neurodegenerative disease such as Alzheimer's disease (AD), natural antioxidants are promising candidates of chemopreventive agents. This study examines antioxidant and neuronal cell protective effects of various fractions of the methanolic extract of Erigeron annuus leaf and identifies active(More)
In vitro antioxidant activities and neuronal cell protective effects of ethanol extract from roasted coffee beans were investigated. Colombia arabica coffee (Coffea arabica) green beans were roasted to give medium (230°C, 10 min), city (230°C, 12 min) and french (230°C, 15 min) coffee beans. Total phenolics in raw green beans, medium, city and(More)
The ethylacetate (EtOAc) fraction of blueberry leaf extract was investigated to examine the in vivo antiamnesic effects against amyloid β protein (Aβ)-induced learning and memory deficit. The fraction showed the highest antioxidant activities, and the generation of intracellular reactive oxygen species was significantly decreased. Cell viability assays(More)
BACKGROUND In vitro antioxidant activities and neuron-like PC12 cell protective effects of solvent fractions from aged garlic extracts were investigated to evaluate their anti-amnesic functions. Ethyl acetate fractions of aged garlic had higher total phenolics than other fractions. METHODS Antioxidant activities of ethyl acetate fractions from aged garlic(More)
