5-O-Cinnamoylquinic acid is primarily recognized for its antioxidant properties, making it valuable in the formulation of skincare products. It helps protect the skin from oxidative stress caused by environmental factors like UV radiation and pollution. Additionally, it is studied for its potential anti-inflammatory effects, which could be beneficial in treating skin conditions such as acne or eczema. In the food industry, it is explored as a natural preservative due to its ability to inhibit the growth of certain bacteria and fungi, thereby extending the shelf life of perishable items. Research also suggests its role in supporting metabolic health, particularly in managing blood sugar levels, which could have implications for dietary supplements targeting diabetes or weight management.
