Abstract

AbstractThe compound Honokiol, derived from the bark of Magnolia officinalis, possesses the ability to induce apoptosis and inhibit cellular damage caused by reactive oxygen species. The objective of this study was to investigate the toxicological and histopathological effects of Honokiol on zebrafish (Danio rerio) through conducting a semistatic acute toxicity test involving immersion in an Honokiol‐containing solution. The results showed that the toxic effects of Honokiol on zebrafish were primarily manifested in the liver and gills. When exposed to 0.6 mg/L of Honokiol, it could lead to liver hemorrhage as well as swelling and necrosis of gill tissues, and high concentrations of Honokiol could trigger inflammatory responses. Additionally, research found that Honokiol could induce apoptosis in liver and gill tissues through the P53 pathway and possessed the ability to enhance antioxidation. The present findings significantly contribute to a more profound understanding of the toxic impact of Honokiol and its underlying mechanism, thereby providing a valuable reference for the future safe utilization of Honokiol and related pharmaceutical advancements.
