Potential health benefits of combined extracts from germinated brown jasmine rice (Oryza sativa L.), Moringa oleifera leaves, and Cordyceps militaris

Abstract

ABSTRACTExtracts from powders of geminated brown rice (Oryza sativa L.), Moringa oleifera, and Cordyceps militaris were combined in various ratios and their health-beneficial properties were investigated. All combined extracts exerted the synergistic effects on antioxidant activity as well as inhibitions against α-amylase and α-glucosidase. Extract formulas T4 (70% germinated brown jasmine rice, 20% M. oleifera dry leaves, and 10% C. militaris) and T2 (80% germinated brown jasmine rice, 10% M. oleifera dry leaves, and 10% C. militaris) elicited the significantly highest antioxidant activity and the significantly highest inhibition against α-glucosidase, respectively. Both formulas exhibited the significantly highest inhibition against α-amylase. As compared to each other, extract formulas T4 and T2 possessed the higher glucose consumption-promoting and antiinflammatory activities, respectively. Both formulas were not toxic to normal RAW-264.7 and SW-480 human colon cancer cells. Bioactive compounds with health-supporting properties were identified using UHPLC-QTOF-MS/MS. These combined extracts can be promising therapeutic food.
