Chemical Composition and Antioxidant Activity of Essential Oil from Elsholtzia Bodinieriri Vaniot

Abstract

To study the chemical constituents and antioxidant activity of essential oil from Elsholtzia Bodinieriri Vaniot. [Method] The oil from Elsholtzia Bodinieriri Vaniot was obtained by distillation and identified by gas chromatographmass spectrometer (GC-MS). Antioxidant activity of essential oil was testified through DPPH radical scavenging activity. [Results] The content of essential oil in Elsholtzia Bodinieriri Vaniot was 2.56‰. There were 16 components identified in the essential oil (accounted for 80.29% of all), and eucalyptus alcohol was the highest content component in essential oil (accounted for 43.57%). In the DPPH radical scavenging assay, the reaction time was 60min. In the range of 1.83- 18.29g/mL, the reducing power of essential oil was increased linearly along with its concentration. And its line fitting equation was y = 3.0058x +13.181 ( R2 = 0.9990), which IC50 value was 12.25g/mL. [Conclusion] The essential oil from Elsholtzia Bodinieriri Vaniot has good antioxidant activity.
