This study determined the effect of fermentation by Fresco DVS 1010 starter culture with added probiotic strain Lactobacillus rhamnosus GG and potentially isolate plantarum HM1, at times (0, 8 h) cold storage period (24 h, 4th day, 7th 14th day), on microbial parameters, pH changes, total phenolic content, compounds profile, antioxidant activity buckwheat water- milk-based mashes, flavored cran...

Brachychiton australis (Schott and Endl.) A. Terrac discolor F.Muell. (Malvaceae) are widely grown in Egypt observed as important biological species. Chemical studies of the 70% methanol/water extracts leafy branches both species were carried out based on isolation characterization phytochemical constituents. Chromatographic spectroscopic methods revealed identification twelve phenolics. Eight ...

Phenolic acids existed in many agricultural products especially vegetables and considered as important natural antioxidants. Eleven phenolic commonly were chosen to assess the antioxidant activities using DPPH·, ·ABTS+, ·O2-, ·OH scavenging assays, well ferric reducing power ?-carotene bleaching assays. The results showed that caffeic protocatechuic acid with simple dihydroxylation structures h...

We have investigated the anti-oxidative and glucose-lowering effects of 70% methanolic extract of H. heteroclita fruit pulp (MHE). Anti-oxidative property of MHE was assessed by free radical scavenging assays and compound level screening by LC-MS profiling. In silico analysis and in vivo preclinical validation were also performed using molecular docking and alloxan-induced diabetic model, respe...

OBJECTIVES Stroke poses a crucial risk for mortality and morbidity. Our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats. MATERIAL AND METHODS Rats were randomly divided into four groups, namely Group I (control rats), Group II (ischemia rats), Group III (6 hr ischemia + p-coumaric acid rats) and Group IV (24 hr ischemia + p-coumaric acid rats). Cere...

In this study, we investigated how the extent of ripeness affects the yield of extract, total phenolics, total flavonoids, individual flavonols and phenolic acids in strawberry and mulberry cultivars from Pakistan. In strawberry, the yield of extract (%), total phenolics (TPC) and total flavonoids (TFC) ranged from 8.5-53.3%, 491-1884 mg gallic acid equivalents (GAE)/100 g DW and 83-327 mg cate...

A free and liberated by acid and alkaline hydrolysis phenolic acids from the hips of fourteen species of wildly growing roses were identifed and determined using SPE RP HPLC method. Eleven major phenolic acids (gallic, protocatechuic, gentisic, p-hydroxybenzoic, vanillic, caffeic, syringic, p-coumaric, ferulic. p-hydroxyphenylacetic, salicylic) were quantitatively investigated. The amount of in...

Analysis of phenolic compounds in sixteen Portuguese wild mushrooms species has been carried out by high-performance liquid chromatography coupled to photodiode array detector and mass spectrometer (HPLC-DAD-ESI/MS). No flavonoids were detected in the analysed samples, but diverse phenolic acids namely protocatechuic, p-hydroxybenzoic and p-coumaric acids, and two vanillic acid isomers were fou...

A flow injection analysis (FIA) system was developed for the determination of phosphate efflux from wine lactic acid bacteria (Oenococus oeni and Lactobacillus hilgardii) as an indication of cell membrane damage. The system allowed the direct injection of the cell suspension, avoiding the filtration step, with minimum sample treatment and minimized reagent consumption. The developed system is c...
