title: Profiles of Glucosinolates, Their Hydrolysis Products, and Quinone Reductase Inducing Activity from 39 Arugula (Eruca sativa Mill.) Accessions.
abstract: Glucosinolates, their hydrolysis product concentrations, and the quinone reductase (QR) inducing activity of extracts of leaf tissue were assayed from 39 arugula (Eruca sativa Mill.) accessions. Arugula accessions from Mediterranean countries (n = 16; Egypt, Greece, Italy, Libya, Spain, and Turkey) and Northern Europe (n = 2; Poland and United Kingdom) were higher in glucosinolates and their hydrolysis products, especially glucoraphanin and sulforaphane, compared to those from Asia (n = 13; China, India, and Pakistan) and Middle East Asia (n = 8; Afghanistan, Iran, and Israel). The QR inducing activity was also the highest in Mediterranean and Northern European arugula accessions, possibly due to a significant positive correlation between sulforaphane and QR inducing activity (r = 0.54). No nitrile hydrolysis products were found, suggesting very low or no epithiospecifier protein activity from these arugula accessions. Broad sense heritability (H(2)) was estimated to be 0.91-0.98 for glucoinolates, 0.55-0.83 for their hydrolysis products, and 0.90 for QR inducing activity.
