Component Analysis, Quality Measurement and Antioxidant Activity of Sambucus williamsii Seed Oil

The purpose of this study was to extract Sambucus williamsii (SW) seed oil by supercritical carbon dioxide. Volatile components in SW seed oil were analyzed by GC/MS and 17 volatile components were identified. Physical and chemical indexes of the oil were determined by GB code methods and the results showed that these indexes were in accordance with the Chinese national standards. The antioxidant activity of the oil was evaluated by reducing power assay. A significant and linear correlation coefficient between the reducing power activity and the concentration of SW seed oil was found (R=0.9957). The experimental result suggested that SW seed oil had potential antioxidant activity.
