Bioactive compounds analysis in ethanolic extracts of Citrus maxima and Citrus sinensis exocarp and mesocarp

The composition of phenolic compounds of ethanolic extract taken from mesocarp and exocarp parts of Citrus maxima and Citrus sinensis peels cultivated in Iran have been identified. The Phenolic compounds in ethanolic extracts were quantified using HPLC-DAD. Different amounts of phenolic compounds were detected in the samples including hesperidin, t-ferulic acid, catechin, sinapic acid, vanillin, chlorogenic acid and caffeic acid. The most represented compound in both plants was hesperidin. It was the main phenolic compound detected in both exocarp and mesocarp parts of both species, with the maximum amount belonging to mesocarp of C. sinensis. The average amount of hesperidin detected in mesocarp and exocarp of C. maxima was 15.04 and 7.42 mg g(-1) dry weight, while it was 17.34 and 7.63 mg g(-1) dry weight for C. sinensis.

Automated summary

The composition of phenolic compounds in ethanolic extracts of Citrus maxima and Citrus sinensis peels cultivated in Iran was identified using HPLC-DAD, with hesperidin being the most represented compound. The mesocarp of C. sinensis had the highest amount of hesperidin, with different amounts of phenolic compounds detected in both exocarp and mesocarp parts of the two species.
