Abstract: In order to investigate both the nutritional and edible value of lily petals and select the high-nutrition lily species or cultivars,the basic nutrients of 14 species or cultivars of lily petals were probed. This paper not only detected the nutritive components,active substance,mineral elements and amino acid composition of 14 varieties and compared the results with those of traditional edible lily bulbs referring to relevant literature,but also analyzed the results by using principal component analysis and cluster analysis to develop quality screening and comprehensive evaluation research. The results demonstrated that lily petals were rich in carbohydrate,protein and mineral elements. The principal component analysis of 16 nutrient indicators were carried out,and the cumulative contribution of the 6 principal components was 86.085%. Based on the scores of 14 species or cultivars of lily petal,the top 5 members were ‘L.lancifolium’,the Longiflorum×Asiatic hybrids ‘Dazzle’,L.leucanthum var.centifolium,the Longiflorum×Asiatic hybrids ‘signum’,the Longiflorum×Asiatic hybrids ‘El divo’. Fourteen lily petals were divided into four categories through cluster analysis,according to the result of principal component analysis,‘L. lancifolium’ had comprehensive high quality.In conclusion,this research could provide a theoretical basis for the development and utilization of the germplasm resources of lily petal,diversifying crops producing healthy food and initiating intensive processing of whole crop lily.
