Polyphenol-Rich Citrullus lanatus Rind Extract Mitigates Doxorubicin-Induced Cardiotoxicity: HPLC Profiling and In Vivo Evaluation. (PubMed, Pharmaceutics)
HPLC analysis identified five phenolic acids, i.e., gallic acid, p-hydroxybenzoic acid (PHBA), chlorogenic acid, caffeic acid, and vanillic acid, and two flavonoids, i.e., catechin and hesperetin, with PHBA (163.66 mg/g of extract) being the most abundant. The 500 mg/kg dose demonstrated superior efficacy, comparable to the standard quercetin group. Histopathological examination revealed notable protection of cardiac tissue architecture in the high-dose PRCL-500 group; These findings suggest that PRCL rind extract contains potent compounds having antioxidant and cardioprotective properties and may be used as a natural therapeutic agent against cardiotoxicity.
