Studies on comparison between major nutritional ingredients in different esculent chrysanthemum (Dendranthema × grandiflorum) varieties.

Studies were carried out on the contents of microelements,amino acids,total flavonoids, proteins,soluble sugars,Na and K in ten esculent chrysanthemum ( Dendranthema × grandiflorum) varieties. The results showed that Fe and Zn contents of esculent chrysanthemum were higher and Cu was next; while,Se was the lowest. In general,the microelement contents of Long5 and Xiab were higher than the others. The amino acids showed that,the contents of glutamic acid,aspartic acid,proline and leucine in esculent chrysanthemum were higher. Among different varieties,Amino acid contents of Long4 were the highest. Those of Long5,Long2 and Long1 were the next. Total flavonoid contents of Long1 and Long2 were significantly higher than the others. Protein content of Xiab was the highest. Those of Zaoch,Long2 and Long5 were the next. The differences of soluble sugar,K and Na contents between various varieties were not significant.
