    Abstract:
    OBJECTIVE: To determine the contents of hesperidin, nobiletin and tangeretin in Citrus reticulata 'Chachi' from various habitats and different collecting periods (from October to December) and study the dynamic change of three flavonoids constituents. METHODS: The HPLC method was used for analysis the contents of flavonoids in Citrus reticulata 'Chachi'. The system used a Diamonsil C18 column (250 mm x 4.6 mm, 5 microm) with gradient mobile phase of acetonitrile-methanol (80:20)-2% acetic acid. The monitoring wavelength was at 283 nm and 330 nm and the column temperature was at 25 degrees C with the flow rate of 1.0 ml/min. RESULTS: The contents of hesperidin, nobiletin and tangeretin in Citrus reticulata 'Chachi' collecting from various habitats descended gradually with the mature of fruit, especially in nobiletin and tangeretin. CONCLUSION: The method was simple, convenient and can be used to provide some foundation for the quality control of Citrus reticulata 'Chachi'.
