Phenolic compounds are important inhibitors of the microorganisms used in the Acetone-Butanol-Ethanol (ABE) fermentation. The degradation of phenolic compounds in a wood pre-hydrolysate, a potential substrate for the production of ABE, was studied in this article. First, physicochemical methods for detoxification such as nanofiltration and flocculation were applied and the best combination was ...

The effect of two anti-fungal treatments (metrafenone and boscalid + kresoxim-methyl) on the color and phenolic profile of Tempranillo and Graciano red wines has been studied. To evaluate possible modifications in color and phenolic composition of wines, control and wines elaborated with treated grapes under good agricultural practices were analyzed. Color was assessed by Glories and CIELab par...

We report a flexible de novo synthesis of phenolic dihydroxanthene fluorophores. The synthesis relies on a one-pot formation of an aldehyde intermediate which can be diversified in 60-70% overall yield, providing an efficient access to this family of near-infrared emitting fluorophores.

Total polyphenols content and a partial phenolics composition from pulp and peel of organically and conventionally produced Malus domestica, Annurca were investigated. Furthermore, the antimicrobial effect of these compounds against useful and pathogen microorganism was examined. Finally, their mutagenic activities were evaluated. Organically grown apples showed a greater content of polyphenols...

The induction of carbon-based secondary metabolites in leaves following damage has been proposed to be a result of a shift in the carbon:nutrient balance, when growth is limited by nutrients in relation to carbon. Here we test this hypothesis using seedlings of a tropical tree, Shorea leprosula (Dipterocarpaceae). In the short term, we analysed the phenolic content of leaves 7 d after damage on...

BACKGROUND The five kashayams (kwaths - decoctions) Manjishtadi kashayam (MK), Rasna erandadi kashayam (REK), Sahacharadhi kashayam (SK), Maharasnadi (or Rasna dwiguna bhagam) kashayam (MRK) and Dhanwantharam kashayam (DK) are widely used in the management of diseases manifested due to vitiation of vata and vatarakta (mostly diseases of connective tissues, bones, joints and nervous system). Fre...

In the research it was examined the changes in total phenolic contents and seven major phenolic compounds (gallic acids, +(−) catechin, catechol, Chlorogenic acid, o-coumaric acid, rutin and quercetin) of two litchi cultivars (Purbi and Bedana) shoot tips and fruits (for zygotic embryos) collected in different months, in order to determine their effects on the explants browning during establish...

Plant-derived compounds limiting mycotoxin contamination are currently of major interest in food and feed production. However, their potential application requires an evaluation of their effects on fungal secondary metabolism and membrane effects. In this study, different strains of Fusarium culmorum and F. graminearum sensu stricto were exposed to trans-cinnamic and chlorogenic acids on solid ...

In the present work, the phenolic composition, and antioxidant and antimicrobial properties of twenty-four samples of naturally fermented table olives from the northeast of Portugal were evaluated. The analysis of phenolic composition was performed by HPLC/DAD, and ten compounds were identified, hydroxytyrosol, verbascoside derivate and hydroxytyrosol glycol being the most abundant. Total pheno...

Phenolic profile, antioxidant potential and pigment contents of wild watercress (Nasturtium officinale L.) were studied to assess the potential for future studies and its applications in neutraceuticals and bioactive functional ingredients. Different extracts of watercress (roots, stem and leaves) were analysed for pigment composition, total phenolic contents, and radical scavenging activity. T...
