Floral scent is a crucial characteristic that significantly influences reproductive processes and indicates the ornamental value of many plants. Antique Lotus (, an important ornamental germplasm, has high archaeological and cultural value in China. Although many studies have examined this plant, the floral fragrance characteristics remain unexplored. This study analyzed floral volatile profiles in three floral organs from six Antique Lotus. A combination of dynamic headspace collections and gas chromatography-mass spectrometry analyses revealed a total of 64 volatile components, comprising 38 terpenoids, two benzenoids/phenylpropanoids, and 24 fatty acid derivatives. The stamens were found to contain the greatest number of volatile compounds, while petals exhibit the highest content. Fatty acid derivatives were the primary volatile substances in petals, while stamens and receptacles were dominated by benzenoids/phenylpropanoids. These findings not only lay a foundation for aroma breeding but also provide a theoretical basis for the resource development of Antique Lotus.
花香是一个关键特征，它对植物的繁殖过程有显著影响，并体现了许多植物的观赏价值。古莲是一种重要的观赏种质资源，在中国具有很高的考古和文化价值。尽管已有许多关于这种植物的研究，但花香特性仍未得到探索。本研究分析了六个古莲品种三个花器官中的挥发性成分。动态顶空捕集与气相色谱 - 质谱联用分析相结合，共鉴定出64种挥发性成分，包括38种萜类化合物、2种苯类/苯丙素类化合物和24种脂肪酸衍生物。发现雄蕊中挥发性化合物数量最多，而花瓣中含量最高。脂肪酸衍生物是花瓣中的主要挥发性物质，而雄蕊和花托则以苯类/苯丙素类化合物为主。这些发现不仅为香气育种奠定了基础，也为古莲的资源开发提供了理论依据。
