| Abstract: | "Nutritional, soluble carbohydrates and aroma volatile profiles of Tunisian wild Swiss chard leaves (Beta vulgaris L. var. cicla) have been characterized. The chemical composition of an ethanol chard leaves extract, as well as its in vitro antioxidant, alpha-amylase and alpha-glucosidase inhibition activities were carefully evaluated. The results of the proximate composition showed that total carbohydrate fraction, mainly as dietary fiber were the major macronutrient (2.43?ª+g/100?ª+g fw), being the insoluble dietary fiber the predominant fraction (2.30?ª+g/100?ª+g). In addition, leaves of Beta vulgaris L. were especially rich in Mg, Fe and Ca (4.54, 2.94 and 2.28?ª+mg/100?ª+g fw) and very poor in Na (0.09?ª+mg/100?ª+g fw). Volatile profile revealed that non-terpene derivatives and sesquiterpene hydrocarbons were the essential classes of volatiles in the chard leaves. Myricitrin, p-cumaric acid and rosmarinic acid were characterized. Moreover, the ethanol extract of wild Swiss chard leaves revealed significant antioxidant capacity. Furthermore, a good enzyme inhibitory effects on alpha-glucosidase and alpha-amylase activities were observed. These findings highlighted the potential health benefits of wild Swiss Chard as a source of nutritional and bioactive compounds" |
