BRBs contain chemopreventive -rich composition, including anthocyanins, ellagic acid, ferulic acid, coumaric acid
and quercetin, phytosterols in addition to folic acid and selenium.
DPPH (2,2-diphenyl-l-picrylhydrazyl), ABTS (2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid), Folin-Ciocalteu (FC) reagent, capsaicin, dihydrocapsaicin myricetin, catechin, resveratrol, gallic acid, coumaric acid
, caffeic acid, ferulic acid, sinapic acid, and chlorogenic acid were purchased from Sigma-Aldrich (St.
The coumaric acid
and the hydroxybenzoic acid potentiate the IAA oxidase system, responsible for its inactivation, causing the roots inhibition (Souza Filho & Alves, 2002).
13a 8 Syringic acid nd nd 9 Vanilin nd nd 10 p- Coumaric acid
The damaged and control leaves are statistically similar, although the content of ferulic acid content is higher in the damaged samples, and that of coumaric acid
is higher in the controls.
The chlorogenic acid and coumaric acid
of tomato reduces the effects of carcinogens on body that are generated due to smoking.
HPLC analysis indicated that the major polyphenols in the SFE extracts consisted of chlorogenic acid, caffeic acid, syrigin, procyanidin B2, (-)-epicatechin, cinnamic acid, coumaric acid
, phlorizin and quercetin, of which procyanidin B2 had the highest content of 231.
These esters, most importantly ferulic and coumaric acid
esters, can be synthesized into volatile phenols by yeast.
According to study findings, the ORAC results showed that, of the tested compounds, ferulic acid performed the best, followed by coumaric acid
, propyl gallate, gallic acid and vitamin C (ascorbic acid).
Garlic contains lots of phytochemicals, such as allicin, saponin and coumaric acid
," adds Zied.
Simultaneous determination of quercetin, rutin and coumaric acid
in flowers of Rhododandrum arboreum by HPTLC.
They found that the activity of ferulic acid was greater than that of coumaric acid
, which was greater than that of propyl gallate.
