This study identified the secondary metabolites present and determined the antioxidant activity of 31 edible wild fruits grown in Benguet province, Cordillera Administrative Region, Philippines. Total polyphenol and flavonoid content were estimated using Folin-Ciocalteu and aluminium chloride method respectively. Antioxidant activity was measured through diphenyl-1-picrylhydrazyl assay. Based o...

ALTERATIONS IN BIOCHEMICAL COMPONENTS IN MESTA PLANTS: Yellow vein mosaic disease of mesta (kenaf, Hibiscus cannabinus L.; and roselle, H. sabdariffa L.) is a new entrant to the disease scenario and it is associated with a novel monopartite Begomovirus. Changes in different biochemical parameters in diseased mesta plants were observed as compared to healthy ones. Isozyme pattern and assays of d...

Soymilk is fermented with probiotic lactobacilli (Lactobacillus rhamnosus NCDC 19, 24 and cheese isolates: L. rhamnosus C2, C6 and L. casei NCDC 17, 297) @1.0% for 24 h at 37oC. We find that in fermented soymilk both the inhibition of ascorbate autoxidation, and the reducing activity of polyphenol content and increasing of proteolysis varied with the starters used, but nevertheless are signific...

−− Clarification of apple juice by flocculation and precipitation with bentonite and gelatin is explained on a more systematic basis, essentially through the determination of turbidity and zetapotential. Apple juice was also treated with Polyvinylpolypyrrolidone (PVPP) to remove total polyphenol. Gelatin-particle complex was evaluated as the increase in juice turbidity after the adding of tanni...

the acorn is an edible nut of oak trees (quercus spp.) that had been used for human nutrition for a long time. besides nutritious components, acorn contains considerable amounts of phenolic substances. at present study, two different varieties of iranian oak acorns, namely, q. branti var. persica (qb) and qcastaneifolia var. castaneifolia (qc) were used. the total polyphenol content measured in...

The aim of this study was to examine the possible antioxidant and antidiabetic effects of the aqueous extracts of four Flemingia species in Taiwan. A number of methods were employed for this investigation, including ABTS radical monocation scavenging, FRAP (ferric reducing antioxidant power) method, DPPH (1, 1-diphenyl-2-picrylhydrazyl) radical scavenging, total polyphenol content, total flavon...

Although the beneficial effects of moderate wine intake are well-known, data on antioxidant capacity of grape juices are scarce and controversial. The purpose of this study was to quantify total polyphenols, anthocyanins, resveratrol, catechin, epicatechin, procyanidins, and ascorbic acid contents in grape juices, and to assess their possible antioxidant activity. Eight Vitis labrusca juices--w...

Garlic (Allium sativum L.) is used as both a food and traditional medicine for several illnesses throughout the world. 7 garlic cultivars (Novozamocky, Lumir, Mojmir, Havran, Garpel, Eden Rose, Bjetin) were analyzed in this study. Since modern consumer demands encourage consumption of foods with positive effects on human health, research into nutritional properties chemical composition crops, l...

introduction: tea (camellia sinensis), is the most widely beverage after water across the world. the most important chemical composition in tea is phenolic compounds (catechins) that have antioxidant and anticarcinogenic properties and are benefited for cardiovascular disease. there are two major kinds of tea, black tea and green tea. green tea, is originated in china and dates back to several ...
