Variation of Flavonoids in Different Juices of Citrus Cultivated in China
The aim of this study was to determine the levels of ten flavonoids in hand-squeezed juices from 51 citrus varieties (15 mandarins, 21 sweet oranges, 2 lemons, 4 grapefruits, 3 pumelos and 6 citrus hybrids) cultivated in China. Hesperidin was found to be the major flavonoid followed by narirutin and didymin in orange juice and mandarin juice. The contents of narirutin and didymin in orange juice were considerably higher than those in mandarin juice, respectively. Naringin and narirutin were the major flavonoids in grapefruit juice and pumelo juice, and the total FGs content in grapefruit juice was observably higher than pumelo juice. Only hesperidin and narirutin were detected in lemon juice, which the total FGs content was the lowest among all the citrus juices. PMFs were only detected in orange juices and mandarin juices. The major PMFs in orange juice were sinensetin, nobiletin, and tangeretin, while nobiletin, tangeretin and sinensetin in mandarin juice. The ratios of flavonoids in different species were compared, and there were great differences among different species. For example, the ratios of hesperidin to narirutin in common sweet orange, navel orange, Ponkan and Satsuma mandarins were 6. 59, 3. 74, 12.26 and 2. 59, respectively. The results showed the flavonoids could be used as marker for orange juice adulteration.
