This study aims to investigate the role of PF in modulating HIF\u20101\u03b1\u2010mediated mitophagy both in\u00a0vivo and in\u00a0vitro, thereby elucidating its impact on liver fibrosis. The rat model of hepatic toxicity and chronic inflammation was established via CCl\n                    <jats:sub>4<\/jats:sub>\n                    injection, followed by preventive administration of PF in three dosage tiers (100, 150, 200\u2009mg\/kg\/d). Additionally, HSC\u2010T6 cells were subjected to exposure to cobalt chloride (CoCl\n                    <jats:sub>2<\/jats:sub>\n                    , 200\u2009\u03bcM) to mimic hypoxic conditions. Lentiviral transfection was employed to establish stable cell lines with either overexpression or knockdown of HIF\u20101\u03b1, aiming to delineate the functional significance of HIF\u20101\u03b1 in hepatic stellate cells (HSCs) activation. The severity of liver inflammatory response and fibrotic progression was evaluated with several pathological stainings. Levels of mRNA were detected by qPCR. Expression levels of protein were assayed with Western blot. The protein content and distribution were also visually detected through IHC and IF staining. ROS was detected by DCFH\u2010DA, and mitochondrial membrane potential was quantitatively assessed using JC\u20101 staining. Our results demonstrated that PF treatment significantly reversed CCl\n                    <jats:sub>4<\/jats:sub>\n                    \u2010induced liver fibrosis, effectively reducing hepatic inflammation and oxidative damage. PF also inhibited mitophagy by suppressing the HIF\u20101\u03b1 pathway, thereby attenuating HSCs' activation. This study uncovers a novel mechanism involving HIF\u20101\u03b1\u2010mediated mitophagy in HSCs and provides evidence that PF alleviates hepatic fibrosis by inhibiting this process, leading to reduced inflammation and oxidative damage. These findings suggest that PF could be a natural and vital medicine to treat liver fibrosis.\n
