The antioxidant activity of ferulic acid (1), iso-ferulic acid (2), coniferyl aldehyde (3), methyl ferulate (4), and ethyl ferulate (5) were investigated using 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric-reducing antioxidant power (FRAP) assays and autoxidation of triacylglycerols of commercially available sunflower oil (TGSO). The compounds tested for ability to sc...

In structure of the title compound ammonium ferulate monohydrate, NH(4) (+)·C(10)H(9)O(4) (-)·H(2)O, O-H⋯O and N-H⋯O hydrogen bonds link the ammonium cations, ferulate anions and water mol-ecules into a three-dimensional array. The ferulate anion is approximately planar, with a maximum deviation of 0.307 (2) Å.

The anaerobic biodegradation of ferulate and benzoate in stabilized methanogenic consortia was examined in detail. Up to 99% of the ferulate and 98% of the benzoate were converted to carbon dioxide and methane. Methanogenesis was inhibited with 2-bromoethanesulfonic acid, which reduced the gas production and enhanced the buildup of intermediates. Use of high-performance liquid chromatography an...

Coniferyl ferulate, which is noted for its multiple pharmacological activities and chemical instability, is abundant in Angelica sinensis. In this paper, five methods, namely sonication extraction (SE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE), hydrodistillation (HD) and decoction (DC) for extraction of coniferyl ferulate, as well as ferulic acid, Z/E-ligustilid...

Three alkyl coumarates (hexadecyl coumarate, eicosyl coumarate and docosyl coumarate) and five alkyl ferulates (tetradecyl ferulate, pentadecyl ferulate, heptadecyl ferulate, octadecyl ferulate and nonadecyl ferulate) could be tentatively detected in the partially purified HPLC fraction of Ipomoea carnea subsp. fistulosa by high resolution electrospray ionization mass spectroscopy (HRESIMS). Th...

Gamma-oryzanol, a group of phytosterol ferulates found in rice bran, possesses antioxidative activity and other bioactivities. The kinetics of thermal degradation of gamma-oryzanol in stripped rice bran oil (SRBO) were investigated under heating at 132, 160, 192 and 222 degrees C for 480, 140, 60 and 50 h, respectively. Losses of the overall gamma-oryzanol and its components (cycloartenyl ferul...
