  "abstract": "Exploring bioactive compounds produced by forest plants is essential to reveal their potential as sources of medicinal chemicals. Sumatran benzoin ( Styrax benzoin ), a resin-producing plant, should be promoted as a forest conservation species that yields bioactive compounds with medicinal properties. Isolating the bioactive compounds found in Sumatran benzoin resin is necessary to determine the economic value of this non-timber forest product. The study aimed to isolate phenolics from Sumatran benzoin resin and evaluate their antioxidant activity to uncover the potential of this forest plant as a source of high-value bioactive compounds. The research stages included preparing raw resin material (obtained via bark tapping), followed by isolation, purification, analysis, and antioxidant testing. Sumatran benzoin resin served as the raw material for bioactive compound isolation. Phenolics were isolated through stepwise maceration of the resin using organic solvents of varying polarities to produce a crude extract. The extract was purified via solvent extraction to yield total phenolics (15.39% yield). Fractionation of the phenolics yielded a vanillin isolate (1.34% yield). The compound is in the form of a yellowish-white crystalline powder with a distinctive and soft aroma of vanillin, a density of 1.056 g/mL, a boiling point of 285 °C, a melting point of 81 °C, soluble in alcohol, ether, chloroform, acetic acid and hot water. The quantity of phenolics in Sumatran benzoin resin is large and the antioxidant power of phenolics is strong (IC₅₀ 22.10 < 50 ppm). The main component of the isolate content is identified as vanillin, which is an important compound for pharmaceutical and industrial raw materials. Sumatran benzoin as a woody forest plant needs to be conserved as a producer of bioactives, a global oxygen source and as an economic source for communities around forest areas.",
