Abstract: Plants from the genus Lilium are a rich source of chemical diversity.Currently edible Liliaceae concentrated on traditional varieties such as L.Davidii var.Willmottiae,L.Brownie var. viridulum and L.lancifolium,which are deteriorating because of succession cropping obstacle.Therefore,it’s considerable to select new dual-purpose type varieties.This paper not only studied the nutritive components,active substances and amino acid composition of 12 varieties,but also made a comprehensive evaluation on nutritional quality of lilies with factor analysis.The results demonstrated that the variation coefficient of polyphenols and alkaloids of 12 Lilium species were large,while the variation coefficient of dietary fiber,amino acid and other indicators were relatively small.The contributing rate of cumulative sums of 4 common factors was 90.229%,and the key factors affecting nutrient quality evaluation were functional substances factors,nutrient quality cofactors and carbohydrate factors.According to the comprehensive evaluation,L.regale,L.leucanthum and The Longiflorum× Asiatic hybrids ‘Serrada’ had the highest nutritional quality score,and the traditional edible lilies L.brownie var. viridulum and L.Davidii var. willmottiae (pinglu) also had good nutritional quality.Based on nutrient composition,active material and amino acid composition,this study systematically evaluated 12 Lilium species bulbs to provide a reference for screening new dual-purpose type varieties and enriching the evaluation system of lilies nutrient quality.
