Optimization of the Extraction Process of Essential Oil from Waste Leaves and Stems of Artemisia selengensis by Response Surface Methodology and Activity Analysis
摘要
Abstract
Artemisia selengensis is rich in nutrients,but only its fresh and tender young stems are edible.The discarded leaves and stems are prone to decay and deterioration,causing environmental pollution and hindering the development of a circular economy.In this study,essential oil was extracted from waste leaves and stems of A.selengensis by steam distillation.Based on single-factor experiments,the extraction yield of A.selengensis essential oil was used as evaluation index.Combined with Box-Behnken design(BBD)and response surface methodology(RSM),the optimal extraction conditions were determined as follows:extraction time of 5.5 h,solid-liquid ratio of 1∶18,and sodium chloride concentration of 20％,under which the maximum extraction yield reached 0.49％.The main components of the essential oil were analyzed by gas chromatography-mass spectrometry(GC-MS).The results indicated that the essential oil contained various compounds,including olefins,phenols,fatty acids,alcohols,ketones,and esters.Antibacterial assays showed that the essential oil exhibited inhibitory effects against Staphylococcus aureus,Escherichia coli,and Saccharomyces cerevisiae.The antioxidant results showed that the DPPH radical scavenging rate of the essential oil was(85.84±0.52)％,with a scavenging capacity of(148.43±1.29)μmol Trolox/100 g essential oil,while the ABTS radical scavenging rate was(16.34±0.43)％,with a scavenging capacity of(99.48±6.69)μmol Trolox/100 g essential oil,indicating that the essential oil possessed antioxidant activity.关键词
