花椒，是一种重要的香料植物，富含挥发性成分，在我国已形成多个栽培品种。不同品种间的遗传变异对挥发性成分有显著影响。对11个枣品种的挥发性成分进行了分析，共检测出52种挥发性成分。结果表明，从花椒中提取的挥发性成分中，棕榈酸、（+）-柠檬烯、植醇、β-香芹烯和乙酸松油酯为特征成分，其中棕榈酸和植醇的贡献最大。结合化学计量学和含量分析的结果，三个Z。确定了丁戊二醇化学型：（+）-柠檬烯、β-香芹烯+乙酸松油酯和棕榈酸+植醇。此外，还探讨了其主要成分的积累动态，并确定了Z的最佳收获期。bungependtileaves（7月下旬或8月初）得到澄清。此外，组织化学分析结果表明，萜类化合物主要积累在油细胞中。不同化学型的油细胞数量存在一定差异。结果表明，花椒挥发油中挥发性成分含量较高，可能影响花椒挥发油的产量和质量。结果表明，不同化学型的Z.花椒可能是导致同一种植资源品质差异的重要因素。因此，本文对Z.研究姜花的化学类型和主要化学成分的富集规律，为姜花的开发利用提供有利的保证，具有重要的理论意义和实用价值。资源和质量控制。
Zanthoxylum bungeanumMaxim., an important spice plant, is rich in volatile components and has formed several cultivars in China. Genetic variation among different cultivars has significant effects on volatile components. In this study, a total of 52 volatile compounds were detected from 11 cultivars ofZ. bungeanum, among which palmitic acid, (+)‐limonene, phytol, β‐caryophyllene, and terpinyl acetate were screened as characteristic compounds, with palmitic acid and phytol contributing the most to the volatile composition. Combined with the results of chemometric and content analyses, threeZ. bungeanumchemotypes were identified: (+)‐limonene, β‐caryophyllene + terpinyl acetate, and palmitic acid + phytol. In addition, the dynamics of the accumulation of its main components were explored, and the optimal harvest period forZ. bungeanumleaves (late July or early August) was clarified. Moreover, histochemical analysis results showed that terpenoids were mainly accumulated in the oil cells ofZ. bungeanumleaves, and there were some differences in the number of oil cells in different chemotypes ofZ. bungeanum, which might affect the yield and quality of volatile components. The results showed that the differences of chemical composition among diverse chemotypes ofZ. bungeanummight be an important factor leading to the quality differences of the same planting resources. Accordingly, the study on the classification ofZ. bungeanumchemotypes and the accumulation patterns of major chemical components is of great theoretical significance and practical value as a favorable guarantee for the development and utilization ofZ. bungeanumresources and quality control.
