감귤 과즙의 플라보노이드 조성 특성

초록

Flavonoids in juice of 67 citrus genetic resources were analyzed using LC-MS/MS, in order to increase utilization of genetic resources as both breeding and functional materials. Analytical condition was established for ten kinds of flavonoid components known to exist in citrus fruits such as hesperidin by LC-MS/MS, and the analytical method was verified through specificity, linearity, and detection limit. In citrus juice at 80% coloring stage, content of hesperidin and narirutin were generally high, but in sour orange and grapefruit, naringin contents was higher than hesperidin. Total flavonoid content was high in Hayaka' , Sanguinelli', 'Grapefruit', 'Morita navel', 'Kinok uni' and 'Mihocore' . And 'Dangyuja', Jigak' and 'Byungkuyl' which are Jeju native citrus, has specifically high content of certain flavonoids. These resources could be used as not only sources of functional materials but also breeding materials.
