Fragrance compounds analysis of chrysanthemum

Abstract Chrysanthemum morifolium is one of the four major cut flowers in the world and has important ornamental and economic value. Flower fragrance is an important ornamental character of chrysanthemum, especially for tea and edible chrysanthemum, and the excellent fragrance determines its commercial value. At present, however, chrysanthemum is mostly chrysanthemum fragrance and medicinal fragrance, and the research on chrysanthemum flower fragrance mainly focuses on the composition and content of fragrancetic substances, and there is no clear classification of fragrance types. Here, we divided chrysanthemum fragrance into six categories by sensory evaluation, and detected the fragrance components and contents of every representative chrysanthemum with different fragrance types by GC-MS. In addition, we analyzed the genetic conservative substances of fruity fragrance chrysanthemum with multi-functional development potential, which provided a theoretical basis for creating new chrysanthemum germplasm with specific fragrance types, which was conducive to accelerating the biological breeding process of chrysanthemum with new fragrance types.
