Abstract

Abstract:

In order to characterize the quality of pummelo fruits in Sichuan area, and provide useful information for exploitation and utilization of these pummelo, composition and content of flavor compounds were analyzed. The basic physiology indexes of pummelo fruits were measured and evaluated. High performance liquid chromatography (HPLC) was employed to detect and analyze the sugars, organic acids and volatile compounds of five pummelo cultivars. In addition, 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH), ferric reducing antioxidant power (FRAP) and 2,2'-azino-bis (3-ethylebnzthiozoline-6)-sulphonic aciddiammonium salt (ABTS) methods were used to evaluate the antioxidant activities. The results showed that citric acid, sucrose, gallic acid and naringin were the major organic acid, sugar, phenolic acid and flavonoid of Guanxi Miyou, respectively. Lycopene and β-carotene were the main color of red-fleshed and yellow-fleshed pummelo. Among them, SanhongMiyou had the best color performance, its total flavonoid content was 13.34 mg·g^-1, which was about 1.6 times that of Guanxi Miyou, and the contribution of naringin was the largest, which was 807.47 μg·g^-1, significantly higher than other cultivars. SanhongMiyou had the highest score of principal component analysis (PCA), which had the highest content of total flavonoids than other cultivars,and had the strongest antioxidant capacity, the values of DPPH and ABTS were 133.04 μmol·g^-1 and 5.92 μmol·g^-1, respectively. HuangjinMiyou was rich in the content of total sugar (10.20%), its total acids content (7.5 g·L^-1) was lower than other four cultivars. However, it showed the more serious of granulation phenomenon and the weakest of the antioxidant capacity,andits score of PCA was the second. Comprehensivequality of SanhongMiyou and HuangjinMiyou in Sichuan areawere better than other three cultivars, which could be used as materials for the variety selection and functional processing of pummelo in Sichuan area.
