Abstract

is an important spice and medicinal plant widely utilized in East and Southeast Asia. Non-targeted metabolomics techniques were employed to study the variations in the content and composition of essential oil from during drying at different temperatures: 40°C, 50°C, 60°C, and 70°C. A total of 260 metabolites were detected using gas chromatography-mass spectrometry (GC-MS), mainly terpenoids and aldehydes. Cineole, the most important component, accumulated abundantly in samples dried at 50°C. A higher temperature (70°C) was conducive to the accumulation of aldehydes. Overall, the optimal drying condition for was determined to be 50°C for 50 h. In addition, nine differential metabolites were screened using variable important in projection and value (VIP > 1 and  < 0.05), which may serve as potential flavor markers to differentiate various drying treatments of . This study provides a novel perspective on understanding the dynamic metabolites changes during the drying process, and establishes a theoretical foundation for the refinement and high-quality processing of .

摘要

是一种重要的香料和药用植物，在东亚和东南亚广泛使用。采用非靶向代谢组学技术研究了在40°C、50°C、60°C和70°C不同温度下干燥过程中其精油含量和成分的变化。使用气相色谱-质谱联用仪（GC-MS）共检测到260种代谢物，主要为萜类化合物和醛类。最重要的成分桉叶油素在50°C干燥的样品中大量积累。较高温度（70°C）有利于醛类的积累。总体而言，确定其最佳干燥条件为50°C干燥50小时。此外，利用变量重要性投影和值（VIP>1且<0.05）筛选出9种差异代谢物，它们可能作为潜在的风味标志物来区分其不同的干燥处理。本研究为理解干燥过程中代谢物的动态变化提供了新的视角，并为其精制和高质量加工奠定了理论基础。
