Some research has shown that phytosteryl ferulates
could be therapeutic or preventive agents against gastrointestinal inflammatory diseases.
Other modifications that accompany CAD deficiency include reduced levels of p-coumarate esters and ferulate
ethers, reduced deposition of S or G lignins, and increased deposition of unusual phenylpropane units or aldehydes into lignin or cell walls (Kim et al.
In one such study cinnamate, p-coumarate, ferulate
, caffeate, and p-chloro cinnamate esters of triterpenes betulinic acid, oleanolic acid and ursolic acid were prepared and evaluated for their antimycobacterial activity and it was observed that p-coumarate and ferulate
esters resulted in 8-fold and 4-fold increase of activity of parent triterpenes respectively .
Involvement of Guanylate cyclase and K+ channels in relaxation evoked by ferulate
nitrate in rat aorta artery.
Three active principles are interlocked: ethyl ferulate
, a natural antioxidant with UV absorbing properties, neutralizes dangerous oxygen radicals and reduces the dose of UV radiation which penetrates the skin; camosolic acid, which combats free radicals--one of the main causes of DNA and cell damage; and uridine monophosphate (UMP), a biochemical precursor to the synthesis of nucleotides, supports the repair of DNA in the cell.
The released Na ferulate
was separated from the [Na.
Corn fiber oil (CFO) contains high levels of three natural cholesterol-lowering phytosterol components: ferulate
phytosterol esters, free phytosterols and phytosterol fatty acyl esters.
, a salt of ferulic acid, is used in China for treatment of cardiovascular and cerebrovascular diseases (Wang and Ou-Yang 2005).
The composition of carnosolic acid and ethyl ferulate
fights against free radicals that damage skin cells thus effectively preventing the occurrence of UV damage.
Phenolic components of the cell wall, such as etherified ferulic acid, which acts as a ferulate
bridge between lignin and hemicellulose, also regulate digestibility of smooth bromegrass forage (easier and Jung, 1999).
Cosmetic Active 2 (INCI: Helianthus annuus (sunflower) seed oil, ethyl ferulate
, polyglycetyl-5 trioleate, rosmarinus officinalis (rosemary) leaf extract, water, disodium uridine phosphate) combines ethyl ferulate
and carnosolic acid from rosemary to combat ROS and counteract indirect DNA damage and mutations.
