Boz H. (2015): Ferulic acid in cereals – a review. Czech J. Food Sci., 33: 1–7. Phenolic acids represent the most common form of phenolic compounds in the cereal grain and many other plants. The phytochemical ferulic acid is found in the leaves and seeds of many plants, but especially in cereals. It is the most abundant phenolic acid in common cereals, representing up to 90% of total phenolic c...

Previous studies have reported on the glucose and lipid-lowering effects of ferulic acid (FA) but its anti-obesity potential has not yet been firmly established. This study investigated the possible anti-obesitogenic effects of FA in mice fed a high-fat diet (HFD) for 15 weeks. To assess the antiobesity potential of FA, 32 male Swiss mice, weighing 20-25 g (n=6-8 per group) were fed a normal di...

The association of ferulic acid, an alkali-extractable phenolic acid in amaranth (Amaranthus caudatus L., Amaranthaceae) insoluble fiber (trans-ferulic acid: 620 microg.g-1, cis-ferulic acid: 203 microg.g-1), and non-starch polysaccharides was investigated. Enzymatic hydrolysis of insoluble amaranth fiber released several feruloylated oligosaccharides that were separated using Sephadex LH-20-ch...

Ferulic acid (FA) is widely used as an antioxidant, e.g., as a Ultraviolet (UV) protectant in cosmetics and in various medical applications. It has been produced by the hydrolysis of γ-oryzanol found in rice bran oil soapstock. In this study, the base-catalyzed, homogenous hydrolysis of γ-oryzanol was conducted using various ratios of potassium hydroxide (KOH) to γ-oryzanol, initial concentrati...

Dietary ferulic acid (FA), a significant antioxidant substance, is currently the subject of extensive research. FA in cereals exists mainly as feruloylated sugar ester. To release FA from food matrices, it is necessary to cleave ester cross-linking by feruloyl esterase (FAE) (hydroxycinnamoyl esterase; EC 3.1.1.73). In the present study, the FAE from a human typical intestinal bacterium, Lactob...

Coffee and green tea are two of the most widely consumed hot beverages in the world. Their respective bioavailability has been studied separately, but absorption of their respective bioactive phenolics has not been compared. In a randomised cross-over design, nine healthy subjects drank instant coffee and green tea. Blood samples were collected over 12 h and at 24 h to assess return to baseline...

An ethanolic extract of Allium tuberosum Rottl. demonstrated potent choline acetytrasferase (ChAT) activating activity (45%) among 30 screened Korean edible plants. The ChAT activator of A. tuberoum Rottl. was purified and identified as ferulic acid [4-hydroxy-3-methoxycinnamic acid] via silica-gel open-column chromatography, HPLC, EI-MS, and 1H/13C-NMR. The ferulic acid from A. tuberoum Rottl....

New thiazolidine-4-one derivatives of ferulic acid have been synthesized in one step ("one-pot") by cyclization of ferulic acid hydrazide with different aromatic aldehydes and mercaptoacetic acid. The structure of the synthesized compounds was proved by infrared (IR) and nuclear magnetic resonance (H-NMR) spectroscopy. The in vitro antioxidant potential of the synthesized compounds was evaluate...

Rice is an important energy source for people worldwide. The rice grain consists of an endosperm, a bran layer and a germ. However, polished rice lacks the bran and germ, which are abundant in dietary fiber, vitamins and minerals. Polished rice is one of the main staples in Asian countries. On the other hand, pre-germinated brown rice (PGBR) is rapidly becoming popular as a health food in Japan...

Chronic neuroinflammation and oxidative stress contribute to the neurodegeneration associated with Alzheimer's disease and represent targets for therapy. Ferulic acid is a natural compound that expresses antioxidant and anti-inflammatory activities. Nitric oxide is also a key modulator of inflammatory responses. Grafting a nitric oxide-releasing moiety onto anti-inflammatory drugs results in en...
