Protective Effect of Ethanolic Extract of Djulis Hull on Indomethacin-Induced Gastric Injury

Djulis (Chenopodium formosanum), a pseudocereal crop native to Taiwan, is often utilized as a source of grain in the diet because of its high nutritional value. The hull of djulis is discarded as waste during cooking or processing because of its bitter taste. However, recent studies have shown that djulis hull possesses certain benefits, such as antioxidant, blood sugar-lowering, and gut microbiota-regulating properties. Herein, the gastroprotective activity of ethanolic extract of djulis hull (EEDH) against stomach injury caused by indomethacin (IND) in C57BL/6J mice and its mechanism of action was assessed. Preadministration of EEDH significantly attenuated the gastric ulcer caused by IND in a dose-dependent manner (p p < 0.05). Consequently, EEDH can improve gastric injury by regulating antioxidant status and inhibiting proinflammatory signaling pathways, and has the potential to be developed as a functional food for gastric protection
