The Potential of Flavonoid Antioxidants in Dragon Fruit Skin (Selenicereus undatus) for Cardiovascular Health

Abstract

This study aims to examine the potential of flavonoid antioxidants found in dragon fruit peel (Selenicereus undatus) in supporting cardiovascular health. Flavonoids, as bioactive compounds with antioxidant properties, have an important role in protecting the body from oxidative stress that can damage cells and tissues, including the cardiovascular system. With a qualitative approach through literature studies and library research, this study analyzes secondary data from various scientific sources to explore the effects of flavonoids on reducing the risk of cardiovascular disease. Studies show that the flavonoid content in dragon fruit peel is able to suppress the lipid oxidation process, lower cholesterol levels, and inhibit inflammation which is a major risk factor for cardiovascular disease. In addition, the high antioxidant activity of these flavonoids has the potential to strengthen the walls of blood vessels and improve blood circulation, so that it can prevent atherosclerosis and hypertension. The results of this study support the use of dragon fruit peel as a source of natural antioxidants that have the potential to be used as a supplement in the prevention of cardiovascular diseases. A further recommendation is to conduct clinical research to test the effectiveness of flavonoids from dragon fruit peel in cardiovascular health applications in more depth.
