Abstract:

To determine the most optimal extraction process for angelica volatile oil and its antioxidant activity. In this experiment, authentic Angelica sinensis was used as the test material and the single factor and response surface analysis methods were adopted. The particle size of angelica granules, water addition ratio, and extraction time were investigated. In addition, volatile oil yield was evaluated, and the volatile oil extraction process was optimized. Under the conditions of this process, the volatile oil of A. sinensis was extracted, and the antioxidant activity of the volatile oil was determined based on the DPPH free radical scavenging rate. The results showed that the optimum process parameters were particle size of 24 mesh, water addition ratio of 6, and extraction time of 7 h. Under these conditions, the extraction rate of volatile oil from A. sinensis was high.The antioxidant assay showed that when the concentration of A. sinensis volatile oil was 1.2 mg/mL, the DPPH radical scavenging rate was 51.9%. The process optimized by the single factor and response surface model was stable, and the extraction rate of the volatile oil was high. The volatile oil produced under these conditions had good antioxidant activity, which can provide scientific and rational guidance for clarifying and optimizing the process parameters for extracting A. sinensis volatile oil.

Key words: Angelica sinesis, volatile oil, response surface methodology, antioxidant
