Chemical Composition and Bioactive Properties of <i>Camellia oleifera</i> C. Abel Leaves.

ABSTRACT: Camellia oleifera C. Abel is an economically important oilseed crop. This study aimed to investigate the chemical composition and bioactive potential of its leaf extracts, an underutilized by-product, for cosmetic and pharmaceutical applications. Extracts of C. oleifera leaves were prepared using three solvents (water, 50% ethanol, 95% ethanol) via ultrasonication. The total polyphenol and flavonoid contents were quantified, and key bioactivities, including antioxidant capacity, tyrosinase inhibition, and effects on cell proliferation, were evaluated. The 50% ethanolic extract exhibited the highest total polyphenol (337.24 ± 1.94 GAE/g extract) and total flavonoid (189.23 ± 1.12 mg RE/g extract) contents. This extract also demonstrated superior antioxidant activity, with an I
