Abstract

Varieties of chrysanthemums are among the world's most valuable edible ornamental crops. However, the availability and relationship between the bio-chemicals of chrysanthemums and their morphological variations remain unclear. We developed liquid chromatography mass spectrometry to construct a spectral tag library to identify and quantify chemicals of 7 caffeoylquinic acids, 21 flavones and flavonols, 4 carotenoids, and 13 other compounds in 27 cultivars and representative tea of Chrysanthemum morifolium. A correlation analysis found that more acacetin 7-O-galactoside (23) resulted in lighter colored flowers and less acacetin (43) and kaempferol (44) was associated with yellow flowers. Hot-HO extraction of C. morifolium tea showed that most flavonoids and caffeoylquinic acids dissolved out at 30 min, with 20.977 and 8.958 mg/g GW indicated that C. morifolium, which is used in food and tea, is rich in flavonoids and carotenoids. The results improve our understanding of flavonoid biosynthesis and the mechanisms responsible for flower color.

摘要

菊花品种是世界上最有价值的可食用观赏作物之一。然而，菊花的生物化学物质及其形态变异的可用性和关系尚不清楚。我们开发了液相色谱-质谱联用技术，构建了一个光谱标签库，以鉴定和定量分析 7 种咖啡酰奎宁酸、21 种黄酮类和黄酮醇、4 种类胡萝卜素以及 27 个品种和代表性的菊花中的 13 种其他化合物。相关分析发现，更多的芹黄素 7-O-半乳糖苷（23）导致花色较浅，而芹黄素（43）和山奈酚（44）与黄花有关。菊花茶的热-HO 提取表明，大多数类黄酮和咖啡酰奎宁酸在 30 分钟内溶解，其中 20.977 和 8.958 mg/g GW 表明，用于食品和茶的菊花富含类黄酮和类胡萝卜素。研究结果提高了我们对类黄酮生物合成和花色形成机制的认识。
