Improved antioxidant activities of spice require enrichment of distinct yet closely-related metabolic pathways.

The researchers used a reverse association strategy to identify target metabolic pathways for increased production of phytochemicals. They found enrichment of isoprenoids and fatty acids biosynthetic pathways, indicating a need for enrichment of specific metabolic pathways to achieve improved antioxidant effects in spices.

Effects of topping on rhizome, and analysis of chemical composition, antioxidant activity and α-amylase and α-glucosidase inhibition of the aerial parts in Polygonatum cyrtonema.

Topping the aerial part of Polygonatum cyrtonema increases rhizome yield and saponin content. The stem, leaves, and flowers have strong antioxidant and hypoglycemic activities, along with high polyphenol, flavonoid, protein, and amino acid content. This research suggests the potential for developing these parts for various applications.
