Gallic acid, coumaric acid
, ellagic acid, ferulic acid, mandelic acid and vanillic acid were used as reference standards.
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).
3] reported that coumaric acid
and aqueous leachates of alfalfa leaves caused an increase in alfalfa root diameter due to an expanding of the vascular cylinder and cortex cell layers.
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.
The standard extract contains more than 17% coumarin and parts of coumaric acid
1 Standards Coumaric acid
Catechin Cafeic acid Retention time (minute) 38.
Flavonols, coumaric acid
derivatives and stilbenes were expressed as quercetin, coumaric acid
and transresveratrol equivalents, respectively.
Phytochemicals such as ferulic acid, chlorogenic acid, caffeic acid, coumaric acid
, cinnamic acid, eugenol, berberine have shown synergistic interaction with commercial oral antidiabetic drugs when they are tested in two different cell lines at basal level (Prabhakar and Doble 2009, 2011 a,b,c).
Among phenolic compounds pinocembrin, chrysin and galangin were determined to be present; and 9-octadecanoic acid, palmitic acid, decanoic acid, coumaric acid
and cinnamic acids were demonstrated to exist as organic acids (Table 2).
In spite of the presence of gallic, syringic, chlorogenic, vanillic, caffeic, ferulic, and coumaric acids
in Chenopodium album, only chlorogenic acid was identified as a principle allelochemical (Mallik et al.
