牡丹是我国重要的观赏植物，主要有三种：牡丹、芍药和伊藤杂交牡丹。黄色的芍药很受欢迎。然而，芍药黄花形成的化学机制尚不清楚。本研究选取了14个具有代表性的样品：芍药品种3个，芍药品种4个，黄茶杂交品种3个，伊藤杂交品种3个。采用HPLC-DAD和HPLC-Q-TOF-MS/MS测定样品的花瓣提取物含量。共分离鉴定了29种黄酮类化合物，包括28种黄酮醇苷类和1种查尔酮衍生物。不同品种（种）花瓣中黄酮类化合物的组成和含量存在显著差异。总黄酮含量为19.430 ~ 143.043 mg•g−1DW。所有样品中均检测到黄酮醇苷。从芍药品种“金轮”、黄茶杂交牡丹品种和伊藤牡丹品种中检测到查尔conaringenin 2′- o -葡萄糖苷。样品中查木素2′- o -葡萄糖苷的含量大于总黄酮的43%。黄茶杂交牡丹和伊藤杂交牡丹的色素类型和含量相似。总黄酮，尤其是槲皮素3- o -没食子苷和查尔木素2 ' - o -葡萄糖苷对芍药黄花的形成起着重要作用。本研究结果为全面了解芍药黄花显色的化学机理提供了依据，为芍药黄花育种奠定了基础。
Paeoniaspecies are important ornamental plants, including three types: tree peony, herbaceous peony, and Itoh hybrid peony.Paeoniawith yellow color is desired and becoming popular. However, the chemical mechanism of the formation of yellow flowers inPaeoniais still unclear. In this study, 14 representative samples were selected: four samples of three species ofPaeonia, four herbaceous peony cultivars, three lutea hybrid tree peony cultivars, and three Itoh hybrid peony cultivars. The petal extracts of the samples were determined by HPLC-DAD and HPLC-Q-TOF-MS/MS. In total, 29 flavonoids were isolated and identified, including 28 flavonol glycosides and one chalcone derivative. There were significant differences in the composition and content of flavonoids in petals of different cultivars (species). The total content of flavonoids was between 19.430 and 143.043 mg • g−1DW. Flavonol glycosides were detected in all samples. Chalconaringenin 2′-O-glucoside was detected from one herbaceous peony cultivar ‘Golden Wheel’ lutea hybrid tree peony cultivars, and Itoh peony cultivars. The content of chalconaringenin 2′-O-glucoside in the samples was more than 43% of total flavonoids. The pigment type and content of lutea hybrid tree peonies and Itoh hybrid peonies are similar. Total flavonoids, especially quercetin 3-O-galloylglucoside and chalconaringenin 2′-O-glucoside contribute greatly to the formation of yellow flowers ofPaeonia. The results of this study provide a comprehensive understanding of the chemical mechanism for yellow flower coloration ofPaeonia, and lay the foundation for yellow flower breeding ofPaeonia.
