Abstract
Hyperlipidemia (HLP) is a disorder of human lipid metabolism or transport, primarily characterized by abnormally elevated levels of total cholesterol (TC), triglycerides (TGs), and low-density lipoprotein cholesterol (LDL-C) in the blood. It is a key factor contributing to the development of non-alcoholic fatty liver disease, obesity, diabetes, atherosclerosis, and cardiovascular and cerebrovascular diseases. Statistics show that the prevalence of dyslipidemia among Chinese adults is as high as 35.6%, and it has shown a trend of younger onset in recent years, posing a serious threat to public health. Therefore, the prevention and treatment of dyslipidemia carry significant social significance. The pathogenesis of hyperlipidemia is complex and diverse, and currently used medications are often accompanied by side effects during treatment, making the research and development of new therapeutic approaches a current focus. Numerous studies have shown that flavonoids, which are abundant in most medicinal plants, fruits, and vegetables, exert effects on regulating lipid homeostasis and treating hyperlipidemia through a multi-target mechanism. These compounds have demonstrated significant effects in inhibiting lipid synthesis, blocking lipid absorption, promoting cholesterol uptake, enhancing reverse cholesterol transport, and suppressing oxidative stress, inflammation, and intestinal microbiota disorders. This article reviews the latest progress in the mechanisms of flavonoids in the treatment of hyperlipidemia, providing a theoretical basis for future research on drugs for hyperlipidemia.
