Biological Activities
Compounds
Conditions
Rhododendron oldhamii leaf extract demonstrates significant therapeutic potential by treating the accumulation of fat induced by free fatty acids (FFA) in HepG2 cells. Research indicates that this plant effectively treats non-alcoholic fatty liver disease (NAFLD) through both in vitro and in vivo mechanisms. Specifically, the extract works to treat fatty liver syndrome in mice that have been subjected to a high-fat diet (HFD). Furthermore, the ethyl acetate fraction of the plant helps treat total cholesterol (TC) levels by reducing them in subjects with HFD-induced NAFLD. These combined effects highlight the ability of Rhododendron oldhamii to combat various markers of metabolic dysfunction.
Preparations
Parts used
Rhododendron oldhamii leaf extract has emerged as a promising natural agent for addressing metabolic health concerns. Recent studies indicate that extracts derived from the plant's leaves can significantly improve fatty liver syndrome by increasing lipid oxidation. Specifically, the ethyl acetate fraction of the leaf demonstrates a strong ability to inhibit free fatty acid-induced fat accumulation in cells. Research involving mice suggests that these leaf extracts also help reduce total cholesterol and triglyceride levels in cases of non-alcoholic fatty liver disease. Consequently, the unique phytochemicals found within the Rhododendron oldhamii leaf hold great potential for development as effective natural health products.
