Abstract Hydroxycinnamoyl shikimates were reported in 2005 to be intermediates monolignol biosynthesis. 3-Hydroxylation of p -coumarate, originally thought occur via coumarate 3-hydroxylase (C3H) from -coumaric acid or its CoA thioester, was revealed the action coumaroyl shikimate 3?-hydroxylase (C3?H) utilizing -coumaroyl as substrate, itself derived -coumaroyl-CoA hydroxycinnamoyl-CoA: hydrox...

BACKGROUND Commonly occurring diseases can have the origin in oxidative processes ongoing in the human body. Vegetables of Brassicaceae family are the essential sources of natural antioxidants, especially phenolic compounds, in the human diet. The research was aimed to estimate the content of phenolic compounds in selected vegetables and their quantity changes during hydrothermal processes. M...

Interest in edible beans as nutraceuticals is increasing. In the present study, the individual phenolic acids, the total phenolic content (TPC), the total flavonoid content (TFC), and the antioxidant and antidiabetic potential of 13 varieties of rice beans from China were investigated. Eight phenolic compounds (catechin, epicatechin, p-coumaric acid, ferulic acid, vitexin, isovitexin, sinapic a...

An investigation to optimize the extraction of phenolic acids from black cohosh using a pressurized liquid extractor system was studied with the aim of developing a generalized approach for sample preparation of phenolic compounds from plant matrices. Operating parameters such as solvent composition, solid-to-solvent ratio, temperature, particle size distribution, and number of extraction cycle...

BACKGROUND Hydroxycinnamates (HCs) are mainly produced in plants. Caffeic acid (CA), p-coumaric acid (PA), ferulic acid (FA) and sinapic acid (SA) are members of the HC family. The consumption of HC by human might prevent cardiovascular disease and some types of cancer. The solubility of HCs is increased through thioester conjugation to various compounds such as quinic acid, shikimic acid, mali...

The beneficial health effects of cranberries have been attributed to their (poly)phenol content. Recent studies have investigated the absorption, metabolism and excretion of cranberry (poly)phenols; however, little is known about whether they follow a dose response in vivo at different levels of intake. An acute double-blind randomized controlled trial in 10 healthy men with cranberry juices co...

The aim of the work was to determine main groups polyphenolic compounds in Quercus rubra L. raw materials.
 Materials and methods. leaves annual shoots Northern Red Oak used for research were collected August Lisnyky village Obuhiv district Kyiv Oblast (Ukraine). Determination component composition quantitative content flavonoids (including separately catechins), hydroxycinnamic acids, phe...

Ramie is an important fiber feed dual-purpose crop in China and plays role the national economy. However, ramie yield quality can be reduced after many years of continuous cultivation. Currently, relatively little research has been conducted on rhizosphere metabolites their pathways cropping. Therefore, a healthy group (CK) obstacle groups (XZQG, JZ, DJY, GXD) with 8 cultivation were selected f...
