This study aimed to develop a new type of functional citrus beverage (Citurs-F) containing flavonoids extracted from the young fruits of satsuma mandarin ($Citrus$ $unshiu$) and matured fruits of Jeju native dangyooja ($C.$ $grandis$). We made beverages that contained 30% of satsuma mandarin extract with different percentages of concentrated dangyooja-derived flavonoid extracts. In sensory evalution, the highest response indices of color, taste and aroma were from the beverages based on the 30% young fruit extracts plus 15% (Citrus-F-15) and 20% (Citrus-F-20) flavonoids extract from the dangyooja using the KILO prep. In the changes of body weight after oral administration of the Citrus-F, the rat group with HF diet plus the Citrus-F decreased the body weight compared to the rat group fed only HF diet. This effect was to be continued for 9 weeks until the end of experiment. In the lipid content in blood, the rat group with oral administration of citrus extractions merely tended to resolve it in serum test. However, all the 0.1% Citrus-F-15 and Citrus-F-20 treated rat groups from the beginning or after 5 weeks appeared the lowest lipid contents in the blood. In the cholesterol contents, the rat group feeding the KILO-prep's extraction from the beginning weren't significantly recognized them in the group but the rat group feeding 0.1% Citrus-F-15 acted to reduce in the cholesterol contents from 5 weeks. The results indicated that the Citrus-F-15 with rich flavonoids might be main source alleviating the vascular diseases and obesity in human diet.
