Intracellular antioxidant detoxifying effects of diosmetin on 2,2-azobis(2-amidinopropane) dihydrochloride (AAPH)-induced oxidative stress through inhibition of reactive oxygen species generation.
Diosmetin could significantly restore AAPH-induced increase of intracelluar antioxidant enzyme (SOD, GPx, and CAT) activities to normal levels, as well as inhibit intracellular malondialdehyde (MDA) formation. Expand
Interaction between four flavonoids and trypsin: effect on the characteristics of trypsin and antioxidant activity of flavonoids
Summary Interaction of flavonoids and enzyme may affect characteristics and physiological activities of both components. In this study, the effects of the interaction between four flavonoidsExpand
Aged Oolong Tea Reduces High-Fat Diet-Induced Fat Accumulation and Dyslipidemia by Regulating the AMPK/ACC Signaling Pathway
EAOTs may inhibit obesity by up-regulating energy expenditure and fatty acid oxidation while inhibiting fatty acid synthesis and inflammation. Expand
Preparative separation of flavonoids in Adinandra nitida leaves by high-speed counter-current chromatography and their effects on human epidermal carcinoma cancer cells
Abstract Preparative separation of camellianins A and B in Adinandra nitida leaves, which is a flavonoid-rich plant source with great practical prospects, was conducted by high-speed counter-currentExpand
Recrystallization of dihydromyricetin from Ampelopsis grossedentata and its anti-oxidant activity evaluation.
DMY treatment significantly inhibited the obvious increase of anti-oxidant enzymes levels (superoxide dismutase [SOD]; glutathione peroxidase [GPX], and catalase [CAT]) induced by AAPH radicals, suggesting that stress defense mechanisms are associated with protection of DMY against intracellular oxidation.

Preparation, purification and identification of cadmium-induced osteoporosis-protective peptides from chicken sternal cartilage
Abstract Five novel peptides (GGAP, QIGPA, QLGPA, MPKYA and QGPAN) were identified from the purified sub-fraction (F1-c) of chicken sternal cartilage hydrolysate produced using alcalase (E/S 0.50%,Expand
Purification, Characterization, and Bioactivities of Polyphenols from Platycladus orientalis (L.) Franco.
Molecular docking studies indicated that apigenin, myricetin, luteolin, kaempferol, and quercetin effectively inhibit xanthine oxidase by forming hydrogen bonds with the amino acid residues and binding to the active site of the enzyme. Expand
Preparation and Physicochemical Properties of the Complex of Naringenin with Hydroxypropyl-β-Cyclodextrin
The result showed that naringenin had been molecularly dispersed in the HP-β-CD matrix, not forming a new compound and HPLC analysis showed that the solubility of naringein in water was enhanced from 4.38 μg/mL to 1,272.31 μg/ mL. Expand
A polysaccharide isolated and purified from Platycladus orientalis (L.) Franco leaves, characterization, bioactivity and its regulation on macrophage polarization.
Investigation of the structure and bioactivity of a novel polysaccharide from Platycladus orientalis (L.) Franco leaves attempted to elucidate the regulation of macrophage polarization and support the potential application of POP2 as bioactive ingredient for functional foods. Expand
Tyrosinase inhibitory effects and antioxidative activities of novel cinnamoyl amides with amino acid ester moiety.
Nine cinnamoyl amides with amino acid ester (CAAE) moiety were synthesized by the conjugation of the corresponding cinnamic acids with amino Acid esters, and their inhibitory effects on the activities of mushroom tyrosinase were investigated. Expand
