Phenolic acids and tanshinones are two groups of bioactive ingredients in Salvia miltiorrhiza Bunge. As a heavy metal elicitor, it has been reported that Ag+ can induce accumulations of both phenolic acids and tanshinones in S. miltiorrhiza hairy roots. In this study, the effects of Ag+ treatment on accumulations of six phenolic acids and four tanshinones in S. miltiorrhiza hairy roots were inv...

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...

Humic substances (HS) from well waters, fertilizers, and synthetic phenolic polymers were characterized by elemental and UV-VIS spectroscopic analyses. Capillary zone electrophoresis (CZE) with UV absorption detection was used to analyze the lignin-derived phenolic distribution in the degradation residues after alkaline CuO oxidation of HS samples. Eleven phenols with p-acetyl, vanillyl and syr...

Woodland sage (Salvia nemorosa) is an important native medicinal plant in Iran and is considered as a rich source of phenolic and flavonoids compounds. The present research was conducted with respect to the optimization of medium for biomass accumulation and secondary metabolite production in cell suspension culture of S. nemorosa. In this research the effects of total nitrogen content (0, 15, ...

The influence of phenolic (p-coumaric, caffeic, ferulic, gallic and protocatechuic) acids on glucose and organic acid metabolism by two strains of wine lactic acid bacteria (Oenococcus oeni VF and Lactobacillus hilgardii 5) was investigated. Cultures were grown in modified MRS medium supplemented with different phenolic acids. Cellular growth was monitored and metabolite concentrations were det...

The present work aims to assess the antibacterial potential of phenolic extracts, recovered from plants obtained on the North East of Portugal, and of their phenolic compounds (ellagic, caffeic, and gallic acids, quercetin, kaempferol, and rutin), against bacteria commonly found on skin infections. The disk diffusion and the susceptibility assays were used to identify the most active extracts a...

Ferulic acid is a natural compound that possesses multiple physiological and pharmaceutical functions. The chemical, physical, and pharmaceutical properties of this phenolic acid can be improved by derivatives with other active compounds. This sentence (Hence, such improvements can widen the applications of ferulic acid in the food, cosmetic, and pharmaceutical industries.) has been deleted. Th...

Phenolic compounds in loquat fruit were identified as 5-caffeoylquinic acid (chlorogenic acid), neochlorogenic acid, hydroxybenzoic acid, 5-p-feruloylquinic acid, protocatechuic acid, 4-caffeoylquinic acid, epicatechin, o-coumaric acid, ferulic acid, and p-coumaric acid. Neochlorogenic acid was found to be dominant in the early stages of loquat fruit development. Both the concentrations and typ...

Background: Sugarcane is widely consumed by people of the tropics and subtropics. Antioxidants in concentrated sugarcane extracts extracted from sugarcane products using resins are highly stable, and their antioxidant activity is not significantly reduced by prolonged heating or clarification. Methods and Results: This study investigated the extraction processing and evaluated the antioxidant a...

This paper presents grey structure activity relationship analysis for phenolic acid phenethyl esters from the bioactivity on oral cancer SAS, OEC-M1 and human breast cancer MCF-7. First of all, 14 compounds of phenolic acid phenethyl esters are synthesized, while the bioactivity (cytotoxicity) on the cancer cells SAS, OEC-M1, MCF-7 is tested. Next, the relationship weighting of functional group...
