Effects of Microbial Utilization of Phenolic Acids and their .

Reversible sorption of phenolic acids by soils may provide some protection to phenolic acids from microbial degradation. In the absence of microbes reversible sorption 35 days after addition of 0.5–3 μmol/g of ferulic acid or p-coumaric acid was 8– 4% in Cecil Ap horizon and 3 –38% in Cecil Bt horizon soil materials. The reversibly sorbed/solution ratios r/s for ferulic acid or p . ,Benefits of Citrate Over EDTA for Extracting Phenolic Acids . Benefits of Citrate Over EDTA for Extracting Phenolic Acids from Soils and Plant Debris Blum Udo 2004-09- 2 00:00:00 Journal of Chemical Ecology Vol. 23 No. 2 997 BENEFITS OF CITRATE OVER EDTA FOR EXTRACTING PHENOLIC ACIDS FROM SOILS AND PLANT DEBRIS UDO BLUM Department of Botany North Carolina State University Raleigh North Carolina . ,Benefits of Citrate Over EDTA for Extracting Phenolic Acids . The effectiveness of various citrate extractions to recover ferulic acid a phenolic acid from Cecil Ap and Bt soil and plant surface debris crimson clover rye subterranean clover and wheat was compared with that of EDTA extractions. Citrate extractions were equivalent to or better than EDTA in recovering phenolic acids from soil and plant debris. Citrate unlike EDTA did not interfere .

Appli ion of Optimized Procedure to Cereal Cultivars. The optimized hydrolysis method for phenolic acid extraction from cereal samples was as follows: milled cereal grains 0.2 g were homogenized n = 3 in 0.8 mL aqueous ascorbic acid solution 2.5% 0.2 mL aqueous EDTA solution 0.33 M and 4 mL 3.75 M NaOH to give a final concentration of 3 M .

Phenolic Acid Content and Antioxidant Properties of Extruded .

Extraction was performed with 2 g of sample at a temperature of 60 C with 40 mL of solvent in each cycle by three cycles for 0 min 30 min previously optimized . Four different solvent systems ethanol methanol 80% aqueous ethanol and 80% aqueous methanol were evaluated for the extraction of phenolic acids.
Iron binding efficiency of polyphenols: Comparison of effect . Ascorbic acid AA and Ethylenediaminetetraacetic acid EDTA are commonly used to counter act this reaction and increase iron bioavailability. This study was aimed at determining the effect of AA and EDTA on the echol or galloyl iron binding ability of pure phenolics coffee and tea.

Phenolic acid concentrations in plasma . - PubMed Central PMC Other phenolic acids found were vanillic and homovanillic acid 5;4 . We demonstrated that 3MOGA had the strongest antiproliferative activity followed by 34-DHPAA in HCT 6 colon cancer cells among the phenolic acids found in serum and urine . It appears that the echol group is important to the biological activity.
Phenolic acids: Natural versatile molecules with promising . Phenolic acids are also available commercially as dietary supplements viz. grape seed extract or green tea extract. The supplements are typically supplied as antioxidants but the current research confirmed that vegetables fruits and whole grains provide more health benefits rather than antioxidant supplements so there is a tremendous scope .
