Green mustard leves were found to effectively prevent lipid peroxidation of bovine-brain tissue by ascor-bate/Fe system, The 50% methanol extracts mustard leaves were separated into four solvent faction using n-hexane,. EtOAc, n-BiOH and water. Then n-BiOH fraction exclusively exhibited the antioxidative activities at concentration above 100 $\mu\textrm{g}$/mL/ The n-BuOH fraction was further isolated to a single compound using TLC analysis and silica gel chromatography. The active antiodidative compounds were identified as sinapic acid methyl ester and ferulic acid methyl ester by $^{1}$H-NMR and $^{13}$ C-NMR, The sinapic acid methyl ester and ferulic acid methyl ester were prepared by methylating of sinapic acid and ferulic acid with diazomethane. The results strongly suggested that sinapic acid and ferulic acid could be emplyed as a potential antioxiative agents for preventing the bovine brain lipid peroxidation. lipid peroxidation.

This study was conducted to develop a simultaneous analysis method for ferulic acid, caffeic acid, catechin and taxifolin from Health Functional Food (HFF) Pinus Pinaster bark extract. The simultaneous analytical method for ferulic acid, caffeic acid, catechin and taxifolin is carried out using UPLC-MS/MS. The method validation was performed to determine selectivity, linearity, accuracy, limit of detection (LOD), limit of quantification (LOQ) and precision for ferulic acid, caffeic acid, catechin and taxifolin. LC-MS/MS method was established using an Acquity UPLC BEH $C_{18}$ Column and was applied for these 4 compounds. Product-ion traces, at m/z $194.2{\rightarrow}133$, $180.2{\rightarrow}135$, $290.3{\rightarrow}245$, $304.3{\rightarrow}248$, were used for quantitative analysis of ferulic acid, caffeic acid, catechin and taxifolin, respectively. Excellent linearity ($r^2=0.999$) was observed for ferulic acid, caffeic acid, catechin and taxifolin in the concentration range (50-2500 mg/L). The observed recoveries of these 4 compounds were found to be between 84.9 and 104.9%, while precision was between 1.20 and 4.43% relative standard deviation (% RSD).

The inhibitory effect of ferulic acid and related phenolic compounds on the growth of normal cell lines and can­cer cell line was evaluated by the MTT and XTT methods. Ferulic acid decreased the cell viability of human skin melanoma cells by the MTT method and the cell adhesion activity of human oral epithelioid carcinoma cells by the XTT method. These results suggest that ferulic acid has a potential anticancer activity.

Changes in polyamine titers and enzyme activities during radicle growth of Glycine max were studied in order to investigate the effect of ferulic acid in regulation of polyamine biosynthesis. Among eight compounds used, gallic acid stimulated the radicle growth and ferulic acid inhibited it significantly. During the radicle growth of Glycine max, the content of putrescine was shown the highest level at the second day, while at the fourth day spermidine was the highest and spermine followed. Ornithine decarboxylass (ODC, EC 4.1.1.17) seems to be responsible for biosynthesis of putrescine. As the concentration of ferulic acid (0.001, 0.01, 0.1 mM) treated increased, the content of spermine was gradually enhanced and putrescine was increased at 0.001~0.01 mM, decreased after 0.1 mM concentration but spermidine was not affected. Ferulic acid elevated ODC and S-adenosylmethionine decarboxylass (SAMDC, EC 4.1.1.50) activity. ODC activity was increased more than 120% and SAMDC activity was increased about 50% more than that of the control. Diamine oxidase (DAO EC, 1.4.3.6) activity was enhanced about 20% at low concentration, decreased after then.

Diabetes mellitus (DM) is one of the main global health problems. Chronic exposure to hyperglycemia can lead to cellular dysfunction that may become irreversible over time, a process that is termed glucose toxicity. Our perspective about glucose toxicity as it pertains to the pancreatic β-cell is that the characteristic decreases in insulin secretion are caused by regulated apoptotic gene expression. In this study, we examined whether ferulic acid protects INS-1 pancreatic cells against high glucose-induced apoptosis. High glucose concentration (30 mM) induced glucotoxicity and death of INS-1 pancreatic β cells. However, treatment with 1, 5, 10, or 20 μM ferulic acid increased the cell viability in a concentration-dependent manner. Treatment with ferulic acid dose-dependently decreased the intracellular levels of reactive oxygen species, thiobarbituric acid reactive substances, and nitric oxide in INS-1 pancreatic β cells pretreated with high glucose. These effects influence the apoptotic pathway, increasing the expression of the anti-apoptotic protein Bcl-2 and reducing the levels of pro-apoptotic proteins, including Bax, cytochrome C, and caspase 9. Annexin V/propidium iodide staining indicated that ferulic acid significantly reduced high glucose-induced apoptosis. These results demonstrate that ferulic acid is a potential therapeutic agent to protect INS-1 pancreatic β cells against high glucose-induced apoptosis.

This study aimed to evaluate the dietary effects of ferulic acid-based preparation on the performance, blood profiles, and microflora of broiler chicks. A total of 400 chicks (1 day old Ross × Ross) were divided into 20 groups and assigned to four treatments: a basal diet (control) or a treatment diet containing 0.1%, 0.2%, or 0.3% ferulic acid-based preparation. The birds were fed from 1 to 30 d of age. Average daily gain improved compared to that in the control group in all periods (P<0.05). There was no significant difference between treatments in Average daily feed intake during all periods. Feed conversion ratio during starter (day 1 to 21) and total day 1 to 30 periods significantly improved (P<0.05) in the treatments containing ferulic acid-based preparation compared to that in the control. The total cholesterol levels in all the treatments containing ferulic acid-based preparation were significantly lower than that in the control (P<0.05). The globulin content was significantly higher (P<0.05) in the treatment with 0.2% and 0.3% ferulic acid-based preparations than that in the control and 0.1% ferulic acid-based preparation treatments. Among the treatments, there was no significant difference in the total number of cecal bacteria. The number of lactic acid bacteria significantly increased in all treatments containing ferulic acid-based preparation compared to that in the control (P<0.05). The number of coliforms significantly decreased in all treatments containing ferulic acid-based preparation compared to that in the control (P<0.05). In conclusion, the addition of ferulic acid-based preparation to the diet improved broiler performance, blood profiles, and intestinal flora.

Ferulic acid is a phenolic compound that serves as a major biosynthetic precursor of vanillin in higher plants. We investigated the ability of the 3 commercial enzymes - Ultraflo L, Viscozyme L, and ${\alpha}-Amylase$ - to induce the release ferulic acid from the Ipomoea batatas L. (sweet potato) stem. The rate of release for ferulic acid was optimal when Ultraflo L (1.0%) was used compared with the other enzymes, whereas Viscozyme L was most effective for the release of vanillic acid and vanillin. Thus, these enzymes may be useful for the large-scale production of ferulic acid and other phenolic compounds from sweet potato stem.

The antioxidant effects of 700 ppm ginseng extract, 100ppm caffeic acid, ferulic acid, vanillic acid, or ${\alpha}-topherol$ on the 1% linoleic acid aqueous buffer system was studied by measuring malondialdehyde (MDA) and headspace oxygen. The compounds showed antioxidant activities in the following order: $caffeic\;acid{\geq}ferulic\;acid\;>\;{\alpha}-tocopherol$>ginseng extract>vanillic acid, with the oxidation inhibition ratio of 63.5, 62.9, 52.3, 51.2 and 5.6% of the control according to MDA results. The mixture of 100 ppm caffeic acid, 100 ppm ${\alpha}-tocopherol$ and 700 ppm ginseng extract had a high oxidation inhibition ratio of 91.2%. Headspace oxygen results had a similar trend with the MDA results. Headspace oxygen results showed that the antioxidant activities were in order of ferulic acid>caffeic acid>${\alpha}-tocopherol$>ginseng extract>vanillic acid and headspace oxygen contents were 18.56, 17.78, 17.17, 16.65 and 15.95%, respectively.

Ferulic and caffeic acids are hydroxycinnamic acid derivatives, which are potent plant antioxidants. Their free radical scavenging abilities in aqueous solution exposed to DPPH radical, and chemical stabilities against oxidative stress like high temperature and metal ion, were evaluated. To improve the stability of ascorbic acid solution, ferulic acid or caffeic acid was incorporated into ascorbic acid solution. Stability improvement of ascorbic acid was verified through $SC_{50}$ value change according to storage time. Ascorbic acid in combination with ferulic acid or caffeic acid was encapsulated with high efficiency inside BGsome. In this form, its stability was remarkably enhanced compared to that in free aqueous solution.
