Health functional properties of unhulled red djulis (Chenopodium formosanum) in anti-aging

Red djulis (Chenopodium formosanum) is a native grain plant, and shows that it has anti-oxidant and anti-inflammatory effects. However, it was still unclear whether unhulled red djulis extracts promoted collagen production and anti-aging. This study aimed to explore whether the unhulled red djulis extracts had anti-aging properties. Using unhulled red djulis extracts to treat human fibroblasts for functional analysis, and used HPLC to analyze the effective components of red djulis. This study found that unhulled red djulis extracts can increase the repairing ability of the skin cells, and increased skin-barrier-related genes, antioxidant-related genes expression. In addition, it increased collagen-related genes, and inhibited AGEs and melanin formation. Finally, we isolated six active ingredients from the unshelled Red Julie extract, which can increase collagen. Thus, the unhulled red djulis extracts can affect gene expressions related to the skin barrier, antioxidation, and collagen.
