Microbial Degradation of Rutin

Nature, 1959
COMPARATIVELY little work on the metabolism of rutin has been published. 3,4-dihydroxyphenyl acetic acid and homovanillic acid are found in urine after oral administration of rutin to the rat1,2, and protocatechuic acid accumulates in rat kidney homogenates in the presence of quercetin3.

Rutin in Two Eucalypts

Nature, 1950
MAIDEN1 in 1887 and Smith2 in 1897 noted the presence of rutin (identified by Perkins3) in the leaves of Eucalyptus macrorryncha (F. v. M.) or red stringy bark, which occurs abundantly through the hilly country of Victoria and New South Wales. The increasing importance of rutin in the treatment of capillary fragility has led to the possibility of using

Oscillopolarography of rutin

Chemistry of Natural Compounds, 1978
It has been shown that in the oscillopolarography of rutin the electrochemical reduction is affected by the pH of the solution and the concentration of ethanol. Protonation of the rutin molecules and their adsorption on the electrode in aqueous solutions are observed. The adsorption is reduced by increasing the concentration of ethanol to 50%.

Rutiner kræver mere end rutine

2014
Denne artikel diskuterer teori-praksis relationer ved at rette et overordnet fokus på pædagogisk praksis. I det pædagogiske felt er der en udbredt tendens til at opdele det pædagogiske arbejde i ’videnstunge’ aktiviteter på den ene side og på den anden side aktiviteter, som anses som rent praktiske og angiveligt ’videnstomme’, idet de primært anses for

The determination of rutin in tablets

Journal of the American Pharmaceutical Association (Scientific ed.), 1951
The colorimetric determination of aluminum by means of morin (57,2′,4′-tetrahydroxy-flavonol) has furnished the basis for the colorimetric determination of flavonal compounds. A procedure based on this reaction has been developed for the determination of rutin in tablets.

The occurrence of rutin in sambucus canadensis

Journal of the American Pharmaceutical Association (Scientific ed.), 1949
Using an accepted method for its isolation, the occurrence of rutin has been established in elder during a seasonal growing period. The results show that rutin occurs in amounts up to 0.52 per cent and that there is variation in the amount in plants growing under different conditions. Spectrophotometric assay data are presented.

Theoretical conformational analysis of rutin

Monatshefte für Chemie - Chemical Monthly, 2010
The structural properties of rutin were determined by using a computational multistep progression. In the first step a stochastic strategy based on a molecular mechanics calculation was adopted to obtain a preliminary screening of the low-energy rutin conformations.

Some Physical Properties of Rutin

Journal of the American Pharmaceutical Association (Scientific ed.), 1952
Abstract Approximate solubility of rutin in common solvents and solvent‐water mixtures has been determined at room temperature and near boiling temperatures. Data are presented showing the formation of rutin solvent complexes. Rutin of high purity, free of quercetin and other flavonoids, has been prepared using this principle.
