Abstract

This study investigated the optimal extraction conditions for maximizing oil and bark extract yield from Mangium (Acacia mangium Willd.) using the Soxhlet method and decoction, respectively. Response surface methodology (RSM) was employed to analyze and optimize the effects of extraction time, solid-to-solvent ratio, and particle size. A Box-Behnken design (BBD) with 17 experimental runs was conducted for each extraction method. Statistical analysis revealed that particle size significantly impacted both oil and bark extract yield. Optimized conditions for oil extraction were determined to be 8 hours extraction time, 1:14. g/ml solid-to-solvent ratio, and particle size below 0.850 mm, with a predicted yield of 8.6%. On the other hand, bark extract yield was maximized under 3.55 hours extraction time, 1:11 g/ml solid-to-solvent ratio, and 0.1 cm particle size, achieving a predicted yield of 6.7%. Additionally, a quadratic polynomial model was found the most suitable model for each analysis with an equation of Y= 11.77 0.10A + 12.90B-7.97C+1.41C2 for the seed oil, and Y = 4.44+ 1.44A- 3.68C 0.20A2+0.89C2 for the bark extracts. Moreover, the phytochemical analysis identified Coumarins, Phytosterols, and Quinones in the seed oil, while the bark extract contained Cardiac Glycosides, Flavonoids, Tannins, Quinones, Saponins, and Terpenoids. These bioactive compounds suggest potential applications in cosmetics, external medicines, wood preservative treatment, and other areas requiring antimicrobial and antioxidant properties. This research work has successfully optimized the extraction process for both oil and bark extract from Mangium, and characterized their phytochemical content, revealing. potentially suitable applications.
