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