The propolis used in this study is from Brunei Darussalam, including G. thoracica, H. itama, and T. binghami. This focuses on evaluating phytochemicals, the total content of polyphenols flavonoids, marker compounds, anti-fungal activity Brunei. Until now, research compounds contained still being carried out. However, literature chemical compound limited. results using LC-MS/MS found as many 21 ...

A large amount of phenolic compounds in sweet potato leaves are a potential source antioxidants. However, polyphenol is sensitive under certain food processing, thereby needs innovation such as microencapsulation to maintain its stability. This study aimed determine the encapsulation efficiency and characterization leaf extract using maltodextrin (10% 20%) combined with Konjac glucomannan (0.5%...

Sargassum fusiforme (SF), a perennial brown, is often steamed for consumption. SF contains many bioactive compounds; however, the effect of steaming these compounds unknown. This study investigates phenolic component contents and antioxidant antiaging activities fresh (SF) (SSF) extracts in different solvents (95% ethanol, 95% methanol, hot water). Total polyphenol flavonoid content was highest...

Perennial ryegrass (Lolium perenne L.) contains phenolic compounds esterified to cell walls, and it also soluble in the vacuole. Soluble of perennial may be important performance grazing animals, due their roles as substrates for polyphenol oxidase antioxidants. However, compound profile has not been completely identified, making difficult determine which could animal performance. This review s...

Background Diabetes mellitus type 2 (DM2) is associated with increased oxidative stress and oxidative damage to DNA. An appropriate intake of antioxidants via the diet can improve this disturbed oxidative status [1]. Apples are the most widely consumed fruits in Europe and represent a major source of antioxidants due to their high polyphenol content [2]. Apple pomace as a polyphenol-rich byprod...

Obesity is a metabolic disorder disease and excessive fat accumulation. Synthetic antiobesity (antihyperlipidemic) drugs are considered to cause some side effects. Therefore, the investigation of novel agents, with less adverse effects, major challenge in future research, such as from plant extracts. Thus, this research aimed investigate antihyperlipidemic purified polyphenol water lettuce (Pis...

The effects of copper pollution on the polyphenol content, color, and antioxidant activity of wine, as well as correlations among these factors, were investigated. Copper had clear influences on wine polyphenol content. At low copper concentrations, the concentrations of nearly all polyphenols increased, and the antioxidant activity values of the wine also increased. When the copper concentrati...

Inhibition of copper-mediated DNA damage has been determined for several polyphenol compounds. The 50% inhibition concentration values (IC(50)) for most of the tested polyphenols are between 8 and 480 μM for copper-mediated DNA damage prevention. Although most tested polyphenols were antioxidants under these conditions, they generally inhibited Cu(I)-mediated DNA damage less effectively than Fe...
