چکیده انگلیسی
Lemon fruits are well-known for their economic, nutrition and health values. In this study, the maturity degree, phenolic compounds and antioxidant capacity of Eureka lemon [Citrus limon (L.) Burm. f.] fruits harvested at different months of the year were investigated. We found that the fruits harvested in November outperformed others in terms of weight, total sugar and soluble solid content (SSC). The Ï-coumaric acid, ferulic acid, eriocitrin and hesperidin were the predominant phenolic compounds in lemon fruits. The highest total phenolic content (TPC, 3.49â±â0.05âmg GAEâgâ1 FW), total flavonoid content (TFC, 1.46â±â0.05âmg REâgâ1 FW), sum of individual phenolic acids content (269.36âμgâgâ1 FW) and their antioxidant potency composite (APC) index (100.00%) were found in the pulps of April fruits. The maximum of sum of individual flavonoids content (3098.42âμgâgâ1 FW) exhibited in August. For the peels, the highest TFC (6.35â±â0.24âmg REâgâ1 FW) and APC (95.14%) appeared in April fruits, while the highest TPC (7.96â±â0.17âmg GAE gâ1 FW) and sum of individual flavonoids content (9003.91âμgâgâ1 FW) occurred in the August. However, the maximum of sum of individual phenolic acids content (769.28âμgâgâ1 FW) was detected in June fruits. We also found that soluble solid content (SSC) of the pulps of lemon fruits were negatively correlated with their TPC and APC. TPC also decreased with the increase in SSC of peels. Most importantly, our study indicated that the contents of phenolic compounds and antioxidant activity of lemon fruits varied significantly with their maturity degrees depending on different harvest time, and this information is essential for a better use of different lemons fruits resources.
