Abstract

A change in the composition of specialized metabolites is often observed in stressed plants. Phytochemicals play an important role in adapting plants to the environment, particularly overcoming stress conditions such as temperature, humidity, and light intensity. In this study, seasonal variations in the concentrations of volatile organic compounds (VOCs) were analysed in species of . The article presents the effect of sample storage on volatile organic compounds present in liverwort cells and whether the collection habitats of the sample affect the content of phytochemicals. The VOCs of the species within the liverwort were analysed by GC-MS. Compounds were isolated from plant material using the HS-SPME technique. The samples were collected over several years (2019-2021). Of the several dozen samples collected, 79 compounds were isolated, of which 47 were identified.

摘要

在胁迫环境下，植物的次生代谢产物组成通常会发生变化。植物化学物质在植物适应环境方面发挥着重要作用，特别是在克服温度、湿度和光照强度等胁迫条件方面。在这项研究中，分析了种植物中挥发性有机化合物 (VOC) 的季节性变化。本文介绍了样品储存对存在于地钱细胞中的挥发性有机化合物的影响，以及样品的采集生境是否会影响植物化学物质的含量。采用 GC-MS 分析了地钱属植物的 VOC。使用 HS-SPME 技术从植物材料中分离化合物。样品是在几年内（2019-2021 年）采集的。在所采集的数十个样本中，分离出了 79 种化合物，其中 47 种得到了鉴定。
