Abstract The essential oil from ponkan peel is rich in various antibacterial and antioxidant components and can be used as an important raw material for food, chemical, and medical industries. This study used cellulase assisted steam distillation to extract essential oil from ponkan peel, and compared it with the traditional steam distillation method. The components of the essential oil extracted by two different methods were detected using gas chromatography-mass spectrometry (GC-MS). The scavenging ability of the essential oil solution against DPPH and ABTS cationic free radicals was measured, and the antioxidant activity of the essential oil extracted by the two different methods was analyzed. A total of 25 components were identified by both methods, with 19 components detected in the essential oil extracted by the cellulase-assisted method and 22 components detected in the essential oil extracted by steam distillation. The main components were terpenes and alcohols, with small amounts of aldehydes, phenols, hydrocarbons, etc. Studies on antioxidant activity indicated that both essential oils had good antioxidant properties, with the essential oil extracted by the cellulase-assisted method showing stronger antioxidant activity.
