The experiment was conducted to study the tendency of the change of flavonoids content in pomelo during its growth and development and the characteristics of flavonoids accumulation in different cultivars Guanximiyou. The dried samples of the exocarp, mesocarp, and pulp of Sanhongmiyou and Huangjinmiyou were used for measuring the content of total flavonoids. The results showed that the content of total flavonoids in exocarp decreased first and then increased during growth and development, while the content in mesocarp did not change obviously. Furthermore, the content in pulp showed a decreasing trend. The content in exocarp was the highest at the earlystage, while in mesocarp was the highest at the mature stage of the fruit. The content of total flavonoids in exocarp and pulp of Sanhongmiyou was higher than that of Huangjinmiyou, total flavonoids content in the exocarp of Sanhongmiyou was similar to Huangjinmiyou within 150 days after anthesis. In addition, the variation trend of the two cultivars was consistent throughout the whole growth and development.
