Evaluation of Stability and In vitro Anti-Cancer Activity of Dihydroquercetin Nanoemulsion
Background: Dihydroquercetin (DHQ), also known as taxifolin, is a flavonoid commonly found in many plants. Dihydroquercetin has been documented to have powerful antioxidant activity and many beneficial properties for human health, especially its ability to inhibit certain types of cancer cells. However, its low solubility and bioavailability are major obstacles to biomedical applications. Moreover, DHQ is chemically unstable and quickly degrades when exposed to alkaline conditions. background: Dihydroquercetin (DHQ), also known as taxifolin, is a flavonoid and commonly found in many plants.
