Abstract
Antioxidant compounds are widely present in natural products and play a crucial role in delaying aging and preventing chronic diseases. With the advancement of modern medicine, extracting antioxidant components from natural products for pharmaceutical development has become a research hotspot. This study aims to systematically investigate extraction methods of antioxidants from natural products and evaluate their application value in drug development. By reviewing extensive literature, multiple natural products rich in antioxidants were selected, and advanced extraction techniques such as solvent extraction, supercritical fluid extraction, and enzymatic hydrolysis were employed to extract the components. High-performance liquid chromatography and mass spectrometry were utilized for qualitative and quantitative analysis of the extracts. The study demonstrated successful extraction of various antioxidant active components including flavonoids, polyphenols, and alkaloids from natural products, which exhibited excellent free radical scavenging ability and me tal ion chelating capacity. In terms of drug development, the extracted antioxidant components were applied in the research of anti-tumor, cardiovascular diseases, and neurodegenerative diseases, revealing their effectiveness in improving cellular oxidative stress status, inhibiting inflammatory responses, and protecting cells from damage. Innovatively integrating multiple extraction technologies, this study enhanced the extraction efficiency and purity of antioxidant components, providing new insights into the in-depth research and rational utilization of antioxidants from natural products, and laying a theoretical foundation for developing novel antioxidant drugs based on natural products.
