Quercetin is a kind of flavonoid drugs, which is produced mainly by direct extracting from Flos Sophorae or acid hydrolysing from rutin. In this study, microorganism strains that can transfer rutin to quercetin were isolated from soil, screened by TLC and re-screened by HPLC. As a result, strain D97 with the highest transformation ability was obtained. The hydrolyze enzyme was intracellular enzyme and transformation rate was 75.6% within a system comprising of 50mg wet cells in 4mL of 0.3…

Determination of Rutin and Quercetin in Flos Sophorae with Thin Layer Chromatogram Scanner

A TLCS method has been developed for the simultaneous determination of rutin and quercetin in Flos sophorae using a micro-emulsion consisting of soldium dodecyl sulphate and polyamide film.

Comparative study on in vitro anti-free radical activities of quercetin, isoquercetin, and rutin

Three flavoniods have potent anti-free radical effects in a dose- and glycosyl structure-dependent manner and Rutin demonstrated the greatest potency in hydroxyl free radical and superoxide anion (O2-) models and quercet in demonstrated the lowest while the reversed results was observed in ·OH-caused hepatocellular lipid peroxidation and ·OH/RBC membrane models.

Saccharopolyspora flava sp. nov. and Saccharopolyspora thermophila sp.nov., novel actinomycetes from soil.

The generic position of two aerobic, Gram-positive, non-acid-alcohol-fast actinomycetes was established following the isolation of their PCR-amplified 16S rRNA genes and alignment of the resultant

[Comparative study on the antioxidant capacity of quercetin in vivo and in vitro].

The antioxidant capacity of quercetin was stronger than rutin and comparable to vitamin C both in vitro and in vivo, and there was no remarkable absorption peak of quERCetin on HPLC chromatograms and on the other hand, the peak areas of two unknown peaks near quercetusin peak were increased after intragastric administration.

Pseudomonas moraviensis sp. nov. and Pseudomonas vranovensis sp. nov., soil bacteria isolated on nitroaromatic compounds, and emended description of Pseudomonas asplenii.

Two strains of Gram-negative bacteria isolated from soil by selective enrichment with nitroaromatics were subjected to a polyphasic taxonomic study and two novel species, Pseudomonas moraviensis sp.

MEGA5: molecular evolutionary genetics analysis using maximum likelihood, evolutionary distance, and maximum parsimony methods.

The newest addition in MEGA5 is a collection of maximum likelihood (ML) analyses for inferring evolutionary trees, selecting best-fit substitution models, inferring ancestral states and sequences, and estimating evolutionary rates site-by-site.

Some examples were worked out using reported globin sequences to show that synonymous substitutions occur at much higher rates than amino acid-altering substitutions in evolution.

The neighbor-joining method: a new method for reconstructing phylogenetic trees.

The neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods for reconstructing phylogenetic trees from evolutionary distance data.
