Zanthoxylum bungeanum extracts were prepared using seven solvents: water, methanol, ethanol, acetic acid, ethyl acetate, chloroform, and benzene. The volatile composition in the extracts was qualitatively analyzed using headspace solid-phase microextraction coupled with gas chromatography mass spectrometry detection, and the alkylamide composition was determined using high-performance liquid chromatography. The extract compositions differed with respect to the solvents. A total of 49 volatile components belonging to four groups, terpenoids, alcohols, esters, and ketones, were identified in the extracts. The Z. bungeanum extracts were either ester or terpenoid type, dominated by linalyl acetate. The extracts were divided into three distinct groups based on principal component analysis and hierarchical clustering analysis. Water, methanol, and ethanol extracts could be applied in the food and pharmaceutical industries.
采用水、甲醇、乙醇、乙酸、乙酸乙酯、氯仿和苯七种溶剂制备了花椒提取物。采用顶空固相微萃取-气相色谱-质谱联用技术对提取物中的挥发性成分进行定性分析，采用高效液相色谱法测定烷基酰胺成分。提取物的成分因溶剂不同而有所差异。提取物中总共鉴定出49种挥发性成分，分属于萜类、醇类、酯类和酮类四组。花椒提取物为酯类或萜类类型，以乙酸芳樟酯为主。基于主成分分析和层次聚类分析，提取物被分为三个不同的组。水、甲醇和乙醇提取物可应用于食品和制药行业。
