Helvetica Chimica Acta, 1992
AbstractQuinic acid (1a), shikimic acid (2), and their derivatives were acylated in organic solvents by several lipases and by the protease subtilisin Carlsberg. The most satisfactory results were obtained with methyl (or benzyl) quinate (7a (or 8a)) and lipase from Chromobacterium viscosum adsorbed on Celite, which showed an overshelming preference ...

Colorimetric assay of shikimic acid against quinic acid
Analytical Biochemistry, 1972Abstract Shikimic acid heated with p-hydroxybenzaldehyde and concentrated sulfuric acid produces an intense and stable purple-violet dye with absorption maximum at 590 nm, and can be quantitatively determined in the range from 15 to over 120 ng (0.1 to 0.7 μmole/ml). Under the same conditions quinic acid produces no color reaction. Shikimic acid can

A microcolorimetric method for the determination of shikimic acid
Archives of Biochemistry and Biophysics, 1957Abstract 1. 1. A spectrophotometric determination of shikimic acid, based on the reaction of the periodate oxidation product of shikimic acid with aniline to yield a Schiff's base, is described. 2. 2. Sugars, amino acids, and other organic acid so far tested give no color reaction in the procedure concerned. 3. 3.

1981
A compound of unsuspected importance was isolated in 1885 from the fruit of Illicium religiosum. To this compound was given the name shikimic acid, a name derived from shikimi-no-ki which is the Japanese name for the plant. Shikimic acid (5.7), it transpired from the very elegant studies of much later investigators, is a key intermediate in the ...

Most aromatic compounds in plants are derived from shikimic acid metabolism; many of these substances are phenols. Compounds derived from this pathway are extensively modified and considered under other classes of plant secondary metabolites. Although many types of secondary compounds are produced from intermediates of the shikimic acid pathway (e.g ...

Communications in Soil Science and Plant Analysis, 2001
An uncomplicated, benign-by-design analytical method for the determination of shikimic acid in plant tissue was developed. The method is simple and automated entailing a water extraction followed by liquid chromatographic analyses. Use of reagents, solvents and generation of waste are minimized, and the use of toxic/hazardous reagents is eliminated as ...

Shikimic Acid Pathway: Phenols
2023Plant metabolites having one or more hydroxyl groups attached to an aromatic ring are known as phenols. Phenols are a heterogeneous group of compounds. One of the most important functions of phenols is in plant communication e.g., allelopathy, attracting pollinating and disseminating agents, attracting symbiotic bacteria, and inhibiting pathogens and ...

Preparation of a fluorinated shikimic acid
Journal of Fluorine Chemistry, 1994Abstract The reaction of dialkylaminosulfur trifluoride with shikimic acid (1) gives a single isomer of a product 2 in which two hydroxy groups have been replaced by fluorine.

Shikimic Acid Pathway Metabolites
1981Benzenoid compounds in plants are biosynthesised by two main pathways: the shikimic acid pathway and the acetate-malonate pathway (Chapter 4). In higher plants, a large number of aromatic compounds are derived from phenylalanine, tyrosine and tryptophan, end-products of the shikimic acid pathway.
