Phenolic acids ofIris ensata

Antimutagenic effect of phenolic acids.

In the present study, the Salmonella typhimurium tester strain TA 100 was used in the plate-incorporation test to examine the antimutagenic potential of caffeic, ferulic and cichoric acids extracted from plant species of genera Echinacea (L) Moench, as well as of another phenolic acids, on 3-(5-nitro-2-furyl)acrylic acid (5NFAA) and sodium azide mutagenicity. All tested compounds possess antimu...

The phenolic acids of human urine; paper chromatography of phenolic acids.

In the course of an investigation of the metabolism of aromatic compounds in phenylketonuria, it was found that, along with the abnormal metabolism of phenylalanine in this disease, there are other striking deviations from normal. These are manifested by the excretion of greatly increased amounts of some indole acids (1) and phenolic acids (2,3) which are present in normal human urine in small ...

Phenolic acids in wheat coleoptile cell walls.

The phenolic constituent of nonvascular cell walls of wheat (Triticum aestivum L.) coleoptiles, which yields vanillin upon nitrobenzene oxidation, is not lignin as I previously claimed. It seems to be mainly ferulic acid bonded to carbohydrate, probably by an ester linkage. The acid is associated with a fraction of the wall rich in arabinose and xylose, although it is not known whether it is es...
