L., commonly known as yarrow, is a versatile and widely distributed plant species with a rich history of ethnopharmacological significance. This study aimed to evaluate the comparative differences of inflorescence morphotypes. The phytochemical profile of white and pink inflorescence morphotypes was characterised by a complex of thirty-four phenolic and triterpene compounds. The species has distinct morphotypes of white and pink inflorescence. Phenolic and triterpenic profiles were determined, and individual compounds were quantified in inflorescence, leaf, and stem samples of two morphotypes tested. The antioxidant activity of plant extracts was evaluated by free radical scavenging (ABTS) and ferric-reducing antioxidant power (FRAP) assays. Caffeoylquinic acids predominated in all parts of the plant tested. Chlorogenic acid and 3,5-dicaffeoylquinic acid were the principal compounds in the phenolic profile. Betulin, betulinic acid, and α-amyrin were the prevailing triterpenic components in the triterpenic profiles of morphotypes. The predominant flavonoids in inflorescences were flavones, while in leaves, flavonols were the organ-specific compounds. The quantitative differences were observed between plant parts of morphotypes. Leaves consistently displayed the highest amounts of identified compounds and have been testified as the main source of antioxidant activity. Overall, white inflorescences accumulated a higher total amount of compounds compared to pink ones. The observed differences between morphotypes derived from the same population reflect the differences in specialised metabolites and their chemotypes. This study addresses gaps in knowledge, particularly in phenolic and triterpenic profiling of coloured inflorescence morphotypes, enhancing our understanding of chemotypes and morphotypes within the species.
L.，俗称欧蓍草，是一种用途广泛且分布广泛的植物物种，具有丰富的民族药理学意义历史。本研究旨在评估花序形态型的比较差异。白色和粉色花序形态型的植物化学特征由34种酚类和三萜类化合物组成的复合物表征。该物种有白色和粉色花序的明显形态型。测定了酚类和三萜类成分，并对两种测试形态型的花序、叶片和茎样本中的单个化合物进行了定量。通过自由基清除（ABTS）和铁还原抗氧化能力（FRAP）测定法评估了植物提取物的抗氧化活性。咖啡酰奎宁酸在所有测试的植物部位中占主导地位。绿原酸和3,5 - 二咖啡酰奎宁酸是酚类成分中的主要化合物。桦木醇、桦木酸和α - 香树脂醇是形态型三萜类成分中的主要三萜类成分。花序中主要的黄酮类化合物是黄酮，而在叶片中，黄酮醇是器官特异性化合物。在形态型的植物部位之间观察到了定量差异。叶片始终显示出已鉴定化合物的含量最高，并已被证明是抗氧化活性的主要来源。总体而言，白色花序比粉色花序积累的化合物总量更高。来自同一群体的形态型之间观察到的差异反映了特殊代谢产物及其化学型的差异。本研究填补了知识空白，特别是在有色花序形态型的酚类和三萜类分析方面，增强了我们对该物种内化学型和形态型的理解。
