A mixture of extracts from two common vegetables, red pomegranate and turmeric, when photoexcited at 380 nm, produced almost pure white light emission (WLE) with Commission Internationale d'Eclairage (CIE) chromaticity index (0.35, 0.33) in acidic ethanol. It was also possible to obtain WLE in polyvinyl alcohol film (0.32, 0.25), and in gelatin gel (0.26, 0.33) using the same extract mixture. T...

Bioactive polyphenolics are ubiquitously present in plants and may play an important role in the prevention and management of certain human diseases. Three known flavonoids viz Kaemperol-3-O-rutinoside (1), quercetin-3-O-glucoside (2) and kaemperol-3-O-glucoside (3) and inseparable mixture (1:1) of quercetin-3-O-glucose/galactose (4) were isolated, and identified for the first time from Holarrh...

This review will discuss some of the antioxidant assays and biomarkers/measurements used to assess the effect of dietary components on ameliorating in vivo oxidative stress. Although the development of dietary antioxidants has become a major component of the dietary supplement market, this review will focus on foods (primarily fruits and vegetables) and their impact on biomarkers of oxidative s...

In the 70s, reports began to appear of phenolic metabolites of brown algae with the characteristics of tannins; these compounds, initially termed phaeophyte tannins, marine algal polyphenols or polyphloroglucinols, are known as phlorotannins, the youngest group of plant polyphenolics. Despite over 40 years of research in phlorotannins, this area is still in the exponential growth phase; however...

An ultrasound-enzyme-assisted extraction (UEAE) was optimized to extract, simultaneously, the hydrophilic and lipophilic compounds from three berry pomaces (raspberry, strawberry blackberry). First, an enzyme screening designated a thermostable alkaline protease as most suitable recover, in aqueous medium, highest yields of polyphenols oil efficient way. Secondly, selected coupled ultrasounds (...

Peatlands are shaped by slow litter decomposition, but threshold decomposition rates that allow peat formation remain unclear. Can agroforestry in the tropics be compatible with paludiculture allows formation? We explored determinants of wet agroforests adjacent to tropical peatlands Central Kalimantan (Indonesia) litterbag studies (up 16 weeks) standing sources estimate rate constants, charact...
