Orchids are experiencing wide success in ornamental, medicinal, and food fields. The reason for their success is correlated with both their morphology and metabolomics, the latter linked to their taste and biological effects. Despite many orchids having already been the subject of chemotaxonomic works, some of them are still untapped, like the case of . is one of the most common species of the genus , present in hedgerows, verges, and light woodland, where it is one of the few herbaceous plants able to be unpleasant to herbivorous animals. Essential oil from roots, stems, leaves, and flowers were analyzed via GC/MS analyses, revealing the presence of 70 compounds, with a clear prevalence of coumarin. The high concentration of this metabolite may explain the resistance of to herbivores, being associated with appetite-suppressing properties and a bitter taste. Non-volatile fractions were analyzed via UHPLC-MS analysis revealing the presence of hydroxycinnamic acid derivatives, polyphenols, and glycosidic compounds, probably responsible for their color and fragrance. Taken together, the herein presented results shed light on both the defensive strategy and the chemotaxonomy of .
兰花在观赏、药用和食品领域都取得了广泛的成功。它们成功的原因与其形态学和代谢组学相关，后者与它们的味道和生物效应有关。尽管许多兰花已经成为化学分类学研究的对象，但其中一些仍未被开发，例如 的情况。 是 属中最常见的物种之一，生长在树篱、路边和稀疏林地中，是少数几种会让食草动物感到不适的草本植物之一。通过气相色谱/质谱分析对根、茎、叶和花的精油进行了分析，结果显示存在70种化合物，其中香豆素明显占优势。这种代谢物的高浓度可能解释了 对食草动物的抗性，这与抑制食欲的特性和苦味有关。通过超高效液相色谱-质谱分析对非挥发性成分进行了分析，结果显示存在羟基肉桂酸衍生物、多酚和糖苷类化合物，这些可能是其颜色和香味的来源。综上所述，本文所呈现的结果揭示了 的防御策略和化学分类学。
