摘  要：
Contents of sugar,mineral elements,protein,amino acids,and fatty acid in fruits and leaves of Malus toringoides and Malus transitoria cultivars growing in Luhuo area of Sichuan,China were measured. The results showed that the fruits and leaves of the two alpine crabapples contain abundant nutritional materials. In fruits of the species the total sugar contents were 19. 045% and 19. 163% respectively; the vitamin C contents were 2. 433 mg·kg -1 and 2. 133 mg·kg -1 respectively; the Vitamin B2 contents were 3. 00 mg·kg -1 and 2. 30 mg·kg -1 respectively; the protein contents were 1. 171% and 1. 252% respectively; the content of 17 amino acid were ranged 0. 03% ～ 0. 50% and 0. 03% ～ 0. 45% respectively. The fruits contained complete mineral elements. There was significant difference in contents of Mn, Asp and Cys in fruits between the two species. The index of unsaturated fatty acid in fruits of M. toringoides was higher than that of M. transitoria. In leaves of Malus toringoides and Malus transitoria the polysaccharide contents were 21. 664% and 21. 166% respectively; the vitamin C contents were 2 574. 000 mg·kg -1 and 2 381. 090 mg·kg -1 respectively; the protein contents were 25. 160% and 27. 500% respectively; the contents of N,Ca,Cu,Fe,K,Mg,Mn, Na,P,S,Z and Se were relatively high and there were significant differences in 6 kinds of elements between the two species. There was significant difference in contents of disaccharide and glucose in leaves between the two species. The index of unsaturated fatty acid in leaves of M. toringoides was higher than M. transitoria.
