Dioscorea alata
Céréale tropicale riche en anthocyanines et glucides, utilisée en alimentation.
Dioscorea alata, commonly known as purple yam or ube, is a tropical tuber crop from Southeast Asia valued both as a staple food and for its medicinal properties. It is rich in anthocyanins, diosgenin, allantoin, and resistant starch, contributing to antioxidant, anti-inflammatory, and blood sugar-regulating effects. Modern evidence supports its use as a functional food for metabolic health, while traditional medicine employs it for diabetes and inflammatory conditions.
The anthocyanins (e.g., cyanidin-3-glucoside) in Dioscorea alata exert antioxidant activity by scavenging free radicals and upregulating endogenous antioxidant enzymes via Nrf2 pathway activation. Diosgenin, a steroidal sapogenin, inhibits NF-κB signaling, reducing pro-inflammatory cytokines (TNF-α, IL-6) and COX-2 expression. The mucilage and resistant starch content slow gastric emptying and glucose absorption, improving postprandial glycemic control, while allantoin promotes wound healing through fibroblast proliferation. Additionally, the prebiotic starch enhances short-chain fatty acid production by gut microbiota, supporting metabolic and immune health.
