Analysis of Nutrient Components of Lily Bulbs from Different Origins

In this study, 20 lily bulbs of different varieties and origins were used as materials, and 47 nutrient components were detected and analyzed by correlation analysis, cluster analysis and principal component analysis. The results showed that, lilies of different (variety) species had the same types of nutrients, and their contents had significant differences. Different lily samples contained higher mineral elements such as starch, pectin, protein, amino acids, potassium, and zinc, and lower content of other nutrients. It had the characteristics of high protein, rich in pectin, potassium, zinc, and low in sodium and fat. The contents of total free amino acids (4.96 g/100 g) and total mineral elements (952.98 mg/100 g) in Asiatic hybrids ‘Tresor’ were the highest. The contents of total fatty acids (215.72 mg/100 g), protein (5.36 g/100 g) and fat (836.37 mg/100 g) of L. lancifolium from Manshuihe in Anhui province were the highest. L. duchartrei had the highest contents of total vitamin (26.91 mg/100 g) and coarse fiber (1.19 g/100 g). The oriental lily ‘Sorbonne’ had the highest starch content (22.89 g/100 g), while the OT lily ‘Conca D'or’ had the highest pectin (431.41 mg/100 g) content. Cluster analysis divided L. lancifolium from three origins into one categories. The contents of total free amino acids, fat-soluble vitamins, protein, and monounsaturated fatty acids were prominent in L. lancifolium. It had high edible and medicinal value. The results of principal component analysis showed that ‘Tresor’ bulbs had outstanding performance in multiple nutritional indicators and were suitable for both in ornamental and edible purposes. This research would provide a reference for the development of edible and ornamental lily materials.
