摘　　要：采用水蒸气蒸馏法、超临界CO_(2)提取法提取澳洲檀香精油,利用气相色谱-质谱结合解卷积和保留指数技术分析鉴定澳洲檀香精油成分,并用峰面积归一化法确定精油成分相对含量,同时结合其对DPPH自由基清除能力,比较不同精油之间的抗氧化活性区别。结果显示,与传统水蒸气蒸馏法相比,超临界法提取获得的澳洲檀香精油得油率更高、提取时间更短,其最优工艺提取条件为萃取压力25 MPa、萃取温度75℃、萃取时间4 h,得油率达到2.23%;从水蒸气蒸馏法、超临界提取法所得精油中共鉴定出33种化合物,其主要化学成分基本相同,并均含有较高含量的香榧醇、Z-α-檀香醇、反式,反式-金合欢醇、α-红没药醇、Z-β-檀香醇、澳白檀醇、反式-α-香柠檬醇、β-红没药醇等醇类成分;超临界法提取的精油清除DPPH自由基能力优于水蒸气蒸馏法提取的精油,并具备一定的抗氧化能力。研究结果可为澳洲檀香的高效提取及其精深加工利用提供了理论支持和技术参考。The essential oil of Australian sandalwood was extracted using hydrodistillation and supercritical CO_(2)fluid extraction methods.The components of the Australian sandalwood essential oil were analyzed and identified by GC-MS combined with deconvolution and retention index techniques,and the relative contents of the oil components were determined by normalizing the peak areas.Additionally,the antioxidant activity differences between different oils were compared based on their DPPH radical scavenging abilities.The results showed that,compared to the traditional hydrodistillation method,the supercritical fluid extraction yielded a higher amount of Australian sandalwood essential oil in a shorter period.The optimal conditions for this process were as follows:extraction pressure at 25 MPa,extraction temperature at 75℃,and an extraction duration of 4 hours,resulting in an extraction rate of 2.23%.A total of 33 compounds were identified from the oils obtained through both hydrodistillation and supercritical extraction methods.The primary chemical components measured by these two extraction methods were essentially identical,containing high levels of alcohols such as nuciferol,Z-α-santalol,trans,trans-farnesol,α-bisabolol,Z-β-santalol,cis-lanceol,Z-α-trans-Bergamotol,andβ-bisabolol.The oil extracted via the supercritical method exhibited superior DPPH radical scavenging ability compared to that extracted by hydrodistillation and demonstrated notable antioxidant capacity.This study provides theoretical support and technical reference for the efficient extraction and deep processing of Australian sandalwood.
