        abstract = {Benzoin absolute essential oil is a high-value oleoresin derived from the dried sap of the Styrax benzoin tree.
One type of Styrax benzoin traded in Indonesia is black Sumatran incense. Reflux extraction method with ethanol is used
to gain the benzoin absolute essential oil. The purpose of this study is to investigate the antioxidant activity of benzoin
absolute essential oil produced using ethanol reflux extraction. Antioxidant test showed that black Sumatran Incense has
active antioxidant properties with IC50 value is 90.03; the antioxidant activity shows potential alternative utilization of
this essential oil industry, especially those derived from incense resin and its derivatives.}
