graecum tubers and leaves were expressed as microgram of pyrocatechol
equivalent mg of extracts as shown in Table 1.
not analyzed; (a) the sum includes also 3,5-DMP and 2,5-DMP; (b) additionally 0-16 mg/l of 2,6-DMP, 15-60 mg/l of 2,3,4-trimethylphenol, 0-10 mg/l of 2,4-dibutylphenol, 24-243 mg/l of pyrocatechol
39 g/L for the benzethonium chloride, biuret, modified biuret, and pyrocatechol
violet, respectively, and for [lambda], the TUP results were 0.
Pyro, named after the photographic chemical pyrocatechol
, first flew as a kitten tucked into the jacket of New Brighton-bred Mr Bird as he carried out top secret spying missions for the government over enemy territory.
On nearly all his flights,Bob had tucked inside his flying jacket,Pyro the ginger cat, named after the developing fluid pyrocatechol
Then a chemical such as potassium hydroxide, ethylene diamine pyrocatechol
, or hydrazine selectively etches the material.
The developed potentiometric method used as detector a Pt electrode transducer based on logarithmic dependence, which provided the antioxidant activity of several hydrosoluble antioxidants (ascorbic acid, pyrocatechol
, pyrogallol, caffeic acid, chlorogenic acid, gallic acid, tannic acid, uric acid, l-cysteine, and Trolox).
Dye decolorization in the presence of different redox mediators: Both the dyes were incubated with gourd peel peroxidase in the presence of different redox mediators including; 6-dimethoxy phenol, 1-hydroxy benzotriazol, p-cumeric acid, pyrocatechol
, syringaldehyde, syringic acid, vanillin and veratryl alcohol (1.
3+] using the short-term pyrocatechol
violet colorimetric assay (Kerven et al.
Paper mulberry (broussonetia kazinoke): The extracts of root and bark are potent tyrosinase inhibitors[2, 3] The active moiety has been identified as the pyrocatechol
derivative shown at right.
In this method, protein in the sample binds to a pyrocatechol
violet-molybdate complex, resulting in an absorption shift.
Examples are potassium hydroxide, ethylene diamine pyrocatechol
, and hydrazine.
