The total flavonoids of Houttuynia cordata are determined by UV-Vis spectrophotometry. The extraction condition of flavonoids from Houttuynia cordata includes: the extraction temperature is 70 ̊C, solid-liquid ratio is 1:20, solvent is 80% ethanol, extraction time is 65 min. We studied the antioxidation of flavonoids in Houttuynia cordata, and results showed that flavonoids had strong reducing c...

Antioxidant peptide, referred as Trp-Gly-Pro-Gly-Val-Glu (WGPGVE), was isolated and identified from porcine plasma which hydrolysised 5 h by alkaline protease. The sequence of WGPGVE had hydrophobic amino acids G, V, aromatic W, acidic acid E, well its values hydroxyl, ABTS, DPPH radicals scavenging rates iron chelating rate were improved 30.15%, 10.05%, 38.69%, 51.40% respectively, compared to...

Anthocyanins (ACN) are natural colorants that provide bright colors to food products. However, their limited stability in matrices represents a challenge application. Whey protein (WP) has the potential interact with ACN and enhance color stability. This study compared effects of WP preheating temperature on color, (heat, UV light storage) antioxidation capacity three different commercial ACN-b...

The Yinzhihuang injection, a traditional Chinese medicine, has been the recent target of increasing interest due to its anti-inflammatory properties. The molecular basis by which Yinzhihuang injection could cure Riemerella anatipestifer (RA) serositis in ducks is unclear. This study evaluated the antibacterial, anti-inflammatory and antioxidant effects of Yinzhihuang injection, using disease mo...

We have reported that low-dose, unlike high-dose, irradiation enhanced antioxidation function and reduced oxidative damage. On the other hand, ischemia-reperfusion injury is induced by reactive oxygen species. In this study, we examined the inhibitory effects of prior low-dose X-irradiation on ischemia-reperfusion injury in mouse paw. BALB/c mice were irradiated by sham or 0.5 Gy of X-ray. At 4...

Accumulating evidence has suggested that NAD (including NAD+ and NADH) and NADP (including NADP+ and NADPH) could belong to the fundamental common mediators of various biological processes, including energy metabolism, mitochondrial functions, calcium homeostasis, antioxidation/generation of oxidative stress, gene expression, immunological functions, aging, and cell death: First, it is establis...

Depressive disorder will be the second highest disease burden worldwide, which will impair life quality, reduce productivity, and increase disability and mortality. LBP is the main active fraction purified from Lycium barbarum. The aim of this study was to evaluate the potential therapeutic effects of LBP on depressive mice induced by reserpine, as well as the relevant mechanisms. The antidepre...
