Diplotaxis simplex suppresses postprandial hyperglycemia in mice by inhibiting key-enzymes linked to type 2 diabetes

Abstract Nutritional properties of Diplotaxis simplex Spreng., Brassicaceae, an edible wild cruciferous largely distributed in North Africa, were investigated. Potassium (3690–3780 mg/100 g) and calcium (900–1170 mg/100 g) were the most concentrated minerals. Linoleinic acid was found to be the main fatty acid (25.4–27.7%), followed by palmitic acid (13.2–15.3%). Moreover, lipidic fraction of leaves was characterized by a relatively high rate of ethyl linoleate (14.4%) and phytol (17.6%). Ethyl acetate extract of D. simplex flowers showed concentration-dependent α-amylase (IC50 3.46 m...
