In angiosperms, OMTs (EC 2.1.1.6) are bispecific and catalyze the methylation of caffeic acid to ferulic acid and 5hydroxy-ferulic acid to sinapic acid using S-adenosyl-L-Met as methyl donor. The resulting products, ferulic acid and sinapic acid, may subsequently be converted to the corresponding alcohols that are incorporated in lignins. In gymnosperms, where syringyl lignins are absent, OMTs ...

background: artemisia dracunculus l. belongs to the anthemideae tribe of asteraceae family. this plant has been used in traditional folk medicine. also, it's anti-bacterial, anti-fungal, antioxidant, anti-inflammatory and hepatoprotective activity has been proved. objective: the purpose of this study was to evaluate the antioxidant activity of leaves and inflorescence of a. dracunculus and...

Mustard bran is enriched with bioactive phenolic compounds and glucosinolates, yet it underutilized as a low-value processing by-product. Here, we investigate the effects of solid-state fermentation (SSF) using various food-grade microorganisms (Aspergillus spp., Rhizopus Bacillus subtilis, Saccharomyces cerevisiae) on phytochemical composition antioxidant activities oriental mustard yellow bra...

Abstract: Background: Streptozotocin (STZ) induced neuropathy is widely used preclinical model for diabetic (DN). DN majorly resulted due to nitrosative and oxidative stress by hyperglycemia. Phenolic acids are polyphenols with free radical scavenging anti-inflammatory neuroprotectiveaction. Methods: In this study STZ (55mg/kg, i.p) was administered in male Wistar rats animals hyperglycemia (fa...

The autotoxins of muskmelon are one the most important reasons for continuous cropping obstacle muskmelon, which main components phenolic acids. Phenolic acids can inhibit growth and development plants. purpose this study was to screen strains that degrade in soil. Using as sole carbon source, were isolated screened by dilution plate method, could efficiently various abilities measured HPLC, ef...

The simultaneous extraction and enzymatic hydrolysis of sinapine from a mustard residue was designed for the recovery sinapic acid, high value-added phenolic acid. An initial screening allowed identification sinapoyl esterase activities in commercial cocktails (Depol 740 L, Ultraflo XL, Deltazym VR AC-100, Pectinase-PL “Amano”) mono-enzymatic solution rumen feruloyl esterase. These were not ver...

In 1825 Henry an(l Garot ( 5) isolated an alkaloidlal amine from black mustard seedls. This new natural product was namiied sinapine, an(l in 1897 Gadamer (4) propased its structure (fig 1) to be that of the choline ester of sinapic aci(l. Later studies (10, 11) showed that siniapine is wi(lelv (listributedl among members of the family Cruciferae. This compoun(l appeared to be of bioclhelmlical...
