The compositions and contents of flavonoids in ripe fruits of 25 strains of Xinjiang wild apple (Malus sieversii) and 3 varieties of local cultivated apple (Gala,Xialimeng and Red Crabapple) were measured using ultra-high performance liquid chromatography & quadrupole-time-of-flight mass spectrometer (UPLC-QTOF-MS).The results showed that there were 9 kinds of flavonoids with higher contents in Xinjiang wild apple.The compositions of flavonoids in Xinjiang wild apple and local cultivated apple were almost the same,but their contents had significant difference.The contents of chlorogenic acid,procyanidin B2 and epicatechin in Xinjiang wild apple fruit were much higher than those in local cultivated apple,especially epicatechin.Its content was the highest in GL183,which was 82.13 times of that in Gala.And the contents of chlorogenie acid,procyanidin B2 and epicatechin in Xinjiang wild apple strain GL026,GL030,GL053-1,GL172,GL179 and GL183 were higher than the average level.
