Analysis and evaluation of nutritional components in 6 species of Dendranthema morifolium

Dendranthema morifolium ( Ramat.) Tzvel.cv.‘huangfeiwu', D.morifolium.cv.‘huangshanhuangju', D.Morifolium.cv.‘yinsidaju', D.Morifolium.cv.‘jinsidaju', D.morifolium.cv.‘baixianju'and D.Morifolium.cv.‘bianliangziyu'have long been cultivated in Kaifeng for ornamental.In order to extend and expand the D.Morifolium from viewing to the edible direction, enrich edible species and establish a food industry chain, the contents of water, polysaccharides, crude fat, vitamin C, mineral elements and amino acids in the 6 species of D.Morifolium were analyzed and evaluated.The results showed that the nutrients of D.Morifolium were rich.The contents of water, polysaccharides, vitamin C, crude fat were 70.42% ~88.85%, 18.94% ~25.39%, 21.70 ~62.70 mg/100 g and 3.60% ~ 7.10% respectively. The contents of Fe was 163.84 ~ 234.87 mg/kg, whereas Mg was993.27~2698.55 mg/kg, Ca was 3183.38~5115.60 mg/kg, Zn was 14.54~38.35 mg/kg, K was 26302.43~33070.04 mg/kg, Na was 101.87 ~ 405.48 mg/kg and Mn was 32.71 ~ 43.84 mg/kg. In the same time, 16 kinds of amino acids were determined, including 7 essential amino acids, accounted for 21.80% ~ 29.23% of total amino acids. Nutrition quality in 6 species of D.Morifolium were evaluated by Principal component analysis. Results indicated ‘Huangshanhuangju'and ‘Jinsidaju'were the best species, which could be developed for excellent edible species.
