Relationship between the UPLC Fingerprints of "Chachi" Leaves and Their Antioxidant Activities.

"Chachi" (CRC) leaves contain abundant flavonoids, indicating that they possess good nutritional/pharmacological research and development potential. This study aims to explore chemical antioxidant quality markers based on the spectrum-effect relationship and quality control strategy of CRC leaves. The ultrahigh performance liquid chromatography (UPLC) system was used to establish chromatographic fingerprints of "Chachi" leaves.
