Volvariella volvacea, strain V14, produces multiple forms of extracellular laccase when grown in submerged culture in a defined medium with glucose as sole carbon source, and on cotton waste 'compost' representative of the conditions used for industrial-scale mushroom cultivation. In

The vanillate demethylase genes from Streptomyces sp. NL15-2K were cloned and sequenced. The vanA and vanB gene homologs, which encode the terminal oxygenase subunit (VanA) and the ferredoxin-type reductase subunit (VanB) of the enzyme respectively, were found in the sequenced

Six new acylated flavone C-glycosides, 2''-O-(2'''-methylbutyryl)isoswertisin (1), 3''-O-(2'"-methylbutyryl)isoswertisin (2), 2''-O-(2'"-methylbutyryl)vitexin (3), 2''-O-(2'"-methylbutyryl)orientin (4), 2''-O-(3'",4'"-dimethoxybenzoyl)vitexin (5), and 2''-O-(3'",4'"-dimethoxybenzoyl)orientin (6), and the known flavone C-glycoside, isoswertisin, were isolated from the flowers of Trollius ledebouri. The structures of 1-6 were elucidated by spectroscopic

The HPLC methods for the determination of plasma concentrations of the antispasmodic agent mebeverine (0.01-10 micrograms/mL) and its hydrolysis product veratric acid (0.1-50 micrograms/mL) are presented. Mebeverine was demonstrated to hydrolyze readily in fresh unbuffered human and rat plasma samples
