Exploring Tectona grandis Linn. f. Leaf Extract as a Functional Feed Additive with Antioxidant and Nutraceutical Potential for Livestock
Year: 2025
Type: article
Abstract: This study investigated the phytochemical composition, antioxidant activity, and safety of Tectona grandis leaf extracts at four maturity stages. Ethanolic extracts were screened for secondary metabolites and analyzed using GC–MS, together with heavy metal determination, phenolic profiling, and antioxidant assays. Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, glycosides, tannins, saponins, and coumarins, with clear variation among leaf stages. GC–MS analysis detected multiple bioactive constituents, including phytol, n-decanoic acid, and heptadecenal. These compounds have been previously reported to exhibit antioxidant, antimicrobial, and anti-inflammatory properties. Heavy metal analysis showed very low cadmium concentrations (0.001–0.004 mg/kg), undetectable lead levels (
