Isolation and characterization of ferulic acid carbohydrate esters from corn hull (Zea mays)
… hulls (bran) were hydrolyzed with 30 mM oxalic acid in order to release carbohydrate fragments containing ferulic acid. The fragments which were high in ferulic acid also contained high levels of arabinose, xylose, and galactose, which are characteristic of sugars comprising corn hull …

Interactive Effects of Ferulic Acid and Irradiance on Plant Growth and Photosynthetic Rate
… split plot design, the effects of irradiance and ferulic acid (FA) on growth, biomass allocation and plant photosynthetic capacity were monitored in summer greenhouse experiments. The experimental design consisted of two levels of irradiance (ambient sun conditions and ~60% reduction by one layer …

Hull, ferulic acid, para-coumaric acid content and particle size characteristics of various barley varieties in relation to nutrient availability in ruminants
… to corn. Barley grain contains hydroxycinnamic acids (mainly ferulic acid (FA) and ñ-coumaric acid (PCA)) which are cross-linked to polysaccharides, therefore, limit cell wall degradability in the rumen. Paricle size of barley grain also affects the digestion of barley in the rumen. The …

The protective effects of the antioxidant combination of ferulic acid with vitamins C and E against UV-induced photodamage in human skin cells
This study assessed the ability of 0.8 mM ferulic acid (FA), in combination with vitamins C and E, to reduce the effect of UVA-induced photodamage in human epidermal (HaCaTs) and dermal skin cells (primary human fibroblasts (HFbs) and murine 3T3 cells). Pretreatment with the FA and vitamins C and E …

Allelopathic effects of ferulic, gallic, and vanillic acids on corn (Zea mays L.)
… on the activity of femlic, gallic, and vanillic acids on germination and growth of corn (Zea mays L.), radish (Raphanus sativus L.), and peanut (Arachis hypogaea L.) showed that the inhibitory effects of these acids were concentration and growth variable dependent. Ten days after treatment, …

Effects of Hydroxycinnamates and Exogenous Yeast Assimilable Nitrogen on Cider Aroma and Fermentation Performance
… of tannins (phenolic compounds), and/or acid. The phenolic content of some cider apples far exceeds that of white wine, however most cider fermentation practices are directly taken from white winemaking, not accounting for effects of high concentrations of phenolic compounds on yeast …

Studies on lignin biosynthesis and biodegradation
… of Leucaena leucocephala, a tropical hardwood, ferulic acid enriched with ¹³C at either the 1-, 2-, or 3-C atom of the side chain. The plants were grown hydroponically over extended periods of time (28 days) under aseptic conditions in media containing the ferulic acid precursor, and then the …

The E/Z isomerization step in the biosynthesis of Z coniferyl alcohol in Fagus grandifolia Ehrh.
… Experiments with beech bark and 2-¹⁴C-labelled E ferulic acid, E coniferaldehyde, and E coniferyl alcohol revealed that these compounds were efficiently incorporated into both E and Z isomers of coniferyl alcohol. On the other hand, low incorporation of 2-¹⁴C-labelled Z ferulic acid indicated that …

Biological Activity of Phenolics in Chicks and Rats
… with control-fed birds as did chicks fed 0.5% ferulic acid or 0.5% para-coumaric acid. Hepatic lipid, cytochrome b(,5), cytochrome P-450, serum estradiol, egg weight and egg specific gravity were similar for laying hens fed 6% indulin, 6% arenaceous flour or 0% fiber control diets. Rats fed 6 …

Processi di biorefining per l'estrazione di secondary chemical building blocks da sottoprotti dell'agro-industria
… constituted by simple phenols, phenolic acids, hydroxycinnamic acid derivatives, flavonoids and lignans. As in the case of coke production, the removal of the phenolic contents from biomass upgrades also the residual biomass. Focusing on the phenolic component of agrifood wastes, huge …

Improvement of nutritional characteristics and other health benefits of processed maize food products
… (FTIR), but the insoluble-bound hydroxycinnamic acids were difficult to quantify using standard extraction protocols. Therefore, at the onset of the project, a high-throughput method for the extraction of insoluble-bound hydroxycinnamic acids was developed (Chapter 1). The overall concentration …

Comparative Resistance of Maize populations to the maize weevil,Sitophilus zeamais Motschulsky
… to the maize weevil. An attempt at analysing for ferulic acid content in the maize grain failed due to mechanical faults on the only available Gas chromatography/mass spectropy machine in the chemistry department at the University of Zambia. The analysis of ferulic acid could have provided further …

Characterization of indigestible fiber in diets based on corn and soybean meal or corn, soybean meal, and distiller dried grains with solubles and in feces from pigs fed these diets
… total dietary fiber and phenolic acids in a diet based on corn and soybean meal (SBM), and in a diet based on corn, SBM, and distiller dried grains with solubles (DDGS), as well as in feces from pigs fed these diets. The in-vitro disappearance of DM without and with inclusion of …

Potential functionality and digestibility of oryzanol as determined using in vitro cell culture models
… antioxidant activity among γ-oryzanol, ferulic acid and α-tocopherol was also found. With regard to the hypocholesterolemic capacity of γ-oryzanol, the results suggested that the intact γ-oryzanol was poorly absorbed by intestinal cells in vitro. Therefore, it was speculated that the …

Enhanced large-scale production of laccases from Coriolopsis polyzona for use in dye bioremediation
… of mannan oligosaccharides (MO) as elicitor and ferulic acid as inducer were studied using central composite experimental design in liquid cultures of the three strains. The results showed that MO, either added alone or combined with ferulic acid, enhanced laccase activity in the three different …

Key volatile and nonvolatile off-flavor characterization for nine different hemp protein powders
… samples from hulled seeds had significantly more ferulic acid in comparison to the whole hemp seed origin protein samples, which contained more coumaric and caffeic acid. Hulled hemp seed proteins contained more volatiles such as alcohols, furan, and pyrazines while the whole seed proteins powder …

Polysaccharide utilization by the human colonic bacterium, bacteroides intestinalis DSM 17393
… and the enzyme was able to cleave the ferulic acid side chain of every substrate tested in our studies. Moreover, we demonstrated that the bacteria harboring the esterase-enriched cluster do not metabolize the ferulic acid during growth on wheat bran. Thus, the plant phenolic compound …
