Fractions of waste square timber and waste ordinary plywood were pyrolyzed in a pyrolysis plant equipped with a fluidized bed reactor and a dual char separation system. The maximum bio-oil yield of about 65 wt.% was obtained at reaction temperatures of 450-500 °C for both feed materials. For quantitative analysis of bio-oil, the relative response factor (RRF) of each component was calculated us...

1. The structure of the carbohydrate component of the glycopeptide isolated from the proteolytic digest of ovalbumin has been investigated by chemical and enzymic methods. 2. The results are consistent with the presence of a single carbohydrate prosthetic group, linked through its reducing end group to the peptide chain. 3. Further, all the 2-amino-2-deoxy-D-glucose units appear to be in the N-...

Cereal grains are considered by consumers due to effect on health because of their antioxidant capacity, phenolic content and other phytochemicals. For this purpose, an experiment was conducted to evaluate of morphological and nutritional traits on 10 rice genotypes. Analysis of variance showed a significant different among the genotypes for all traits. Onda, Gharib, Fajr and L2 genotypes had t...

objectives: potato (solanum tuberosum l.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. the objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (solanum tuberosum) cultivars in iran i.e., savalan, agria and sante. materials and methods: phenol...

background & aim: restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) are being imposed because of their carcinogecity . experimental: in this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of  flomideschema parviflorum through response surface methodology by fulin cio-calt...

BACKGROUND Lignocellulosic substrates and pulping process streams are of increasing relevance to biorefineries for second generation biofuels and biochemical production. They are known to be rich in sugars and inhibitors such as phenolic compounds, organic acids and furaldehydes. Phenolic compounds are a group of aromatic compounds known to be inhibitory to fermentative organisms. It is known t...

Glucuronidation, which may take place on the phenolic hydroxyl and carboxyl groups, is a major pathway of metabolism for thyroxine (T4) and triiodothyronine (T3). In this study, a liquid chromatography/mass spectrometry (LC/MS) method was developed to separate phenolic and acyl glucuronides of T4 and T3. The method was used to collect the phenolic glucuronide of T4 for definitive characterizati...

Indo-Malaysian tropical peat swamp forests (PSF) sequester enormous stores of carbon in the form of phenolic compounds, particularly lignin as well as tannins. These phenolic compounds are crucial for ecosystem functioning in PSF through their inter-related roles in peat formation and plant defenses. Disturbance of PSF causes destruction of the peat substrate, but the specific impact of disturb...
