Content of total phenols and total anthocyanins was estimated in edible fruits from Bosnia by photometric methods. Cyanidin-3-galactoside chloride was used as a standard for determination of total anthocyanins, and galic acid served as a standard for determination of total phenols. Total content of phenols was 12.7 mg/g in elderberry fruits, 10.4 mg/g in bilberry, 9.8 mg/g in blackberry, 8.8 mg...

The treatment of paper mill effluent for COD, TOC, total phenols and color removal was investigated using combined activated sludge-ozonation processes and single processes. The combined activated sludge-O3/pH 10 treatment was able to remove around 80% of COD, TOC and color from Kraft E(1) effluent. For the total phenols, the efficiency removal was around 70%. The ozonation post treatment carri...

Laccases (benzene diol: oxidoreductases, EC 1.10.3.2) are able to catalyze the oxidation of various compounds containing phenolic and aniline structures using dissolved oxygen in water. Laccase structural features and catalytic mechanisms focused on the polymerization of aromatic compounds are reported. A description about the most recent research on the biosynthesis of chemicals and polymers i...

Picea smithiana is one of the plants belongs to family pinaceae that has not been explored scientifically from pharmaceutical point of view. The present study targeted to explore the antioxidant potential of Picea smithiana growing in Bhadewah region (Shoj dhar) at the altitude of 11000 feats of Jammu and Kashmir, India. Three types of extracts were prepared from leaf and Bark part of the plant...

A method for the superheated water chromatography of phenols was developed using a poly(styrene-divinylbenzene) (PSDVB) stationary phase. The stationary phase of superheated water chromatography must be stable against the attack of water. A durability test for PSDVB packings and octadecylsilyl (ODS)-silica gels indicated that PSDVB packings were stable in superheated water in the temperature ra...

The aim of the paper is to present microbial transformation reactions as a step in the preparation of drugs or their key intermediates from plant derived compounds. Described are some successful applications of microbial transformation processes for preparation of steroid drugs and/or their important intermediates as well as some microbial transformations of terpenes, alkaloids, flavonoids and ...
