Abstract:
Objective To investigate the dynamic variation of flavonoids contents in the flowers of Citrus grandis at different flowering periods. Methods The content of total flavonoids in the flowers of Citrus grandis was determined by means of ultraviolet-visible absorption spectroscopy ,and the contents of naringin and rhoifolin were determined by HPLC. Results The content of total flavonoids in the flowers during the flower withering period ,the young fruit period ,the blossom period,and the budding period was 306.90 mg.g-1,277.93 mg.g-1,215.55 mg.g-1 and 162.74 mg.g-1 respectively. The naringin content during the above four different periods was 246.31 mg.g-1,213.93 mg.g-1,175.94 mg.g-1 and 130.90 mg.g-1 respectively. The rhoifolin content during the four periods was unchanged. Conclusion The contents of total flavonoids and naringin in flowers of Citrus grandis during flower withering period are the highest.
