A, the cultivar and harvest time (and various other factors) dramatically affect levels of total anthocyanins (pictured), cyanidin, ellagic acid, p-coumaric acid, chlorogenic acid, caffeic acid, ascorbic acid, and pelargonidin in 22 cultivars of field-grown strawberries (redrawn from ref. 54). B, similarly, a variety of factors influence the glucosinolate content of broccoli, which translates directly to NAD(P)H quinone:oxidoreductase 1 (NQO1) induction in Hepa1c1c7 cells (pictured) and is exclusively attributed to sulforaphane content. Data are from 28 broccoli cultivars grown to the three-day-old stage in the authors’ lab, as summarized in reference 13.
