Abstract Horseradish (Armoracia rusticana) is a perennial crop belonging to the Brassicaceae family. Horseradish root is used as a condiment due to its extremely pungent flavour, deriving from the high content of glucosinolates and their breakdown products such as isothiocyanates and other sulfur compounds. Horseradish also has a long history in ethnomedicine. In this study the anti-inflammatory potential of three accessions of Armoracia rusticana on lipopolysaccharide from E. coli treated J774A.1 murine macrophages was evaluated. Our results demonstrate that Armoracia rusticana reduced nitric oxide, tumor necrosis factor-α and interleukin-6 (IL-6) release and nitric oxide(NO) synthase and cyclooxygenase-2 (COX-2) expression in macrophages, acting on nuclear transcription factor NF-κB p65 activation. Moreover Armoracia rusticana reduced reactive oxygen species (ROS) release and increased heme-oxygenase-1 expression, thus contributing to the cytoprotective cellular effect during inflammation.

J Agric Food Chem. 2015 Mar 25;63(11):2947-55. doi: 10.1021/jf505591z. Epub  2015 Mar 16. Correlation
 of quinone reductase (QR) activity and allyl isothiocyanate formation among 
different genotypes and grades of horseradish roots.
Horseradish (Armoracia rusticana)
 is a perennial crop and its ground root tissue is used in condiments 
because of the pungency of the glucosinolate (GS)-hydrolysis products 
allyl isothiocyanate (AITC) and phenethyl isothiocyanate (PEITC) derived
 from sinigrin and gluconasturtiin, respectively. Horseradish roots are 
sold in three grades: U.S. Fancy, U.S. No. 1, and U.S. No. 2 according 
to the USDA standards. These grading standards are primarily based on 
root diameter and length. There is little information on whether root 
grades vary in their phytochemical content or potential health promoting
 properties. This study measured GS, GS-hydrolysis products, potential 
anticancer activity (as quinone reductase inducing activity), total 
phenolic content, and antioxidant activities from different grades of 
horseradish accessions. U.S. Fancy showed significantly higher sinigrin 
and AITC concentrations than U.S. No. 1 ,whereas U.S. No. 1 showed 
significantly higher concentrations of 1-cyano 2,3-epithiopropane, the 
epithionitrile hydrolysis product of sinigrin, and significantly higher 
total phenolic concentrations than U.S. Fancy.
