Abstract:This research explored the differences in phenolic components and antioxidant activities of Passiflora edulis Sims peel from Sichuan，Guangxi and Fujian，China.The results showed that the total phenolic content in P.edulis Sims peel from three producing areas was（20.51±0.56），（20.15±2.20），and（15.89±0.57）mg GAE/g DW，respectively.Seven phenolic compounds were identified from Sichuan，5 from Fujian and 4 from Guangxi，and the sample from Sichuan contained two unique polyphenols: ellagic acid and sinapic acid-O-hexose，which were different from the other two areas.The rutin content in P.edulis Sims peel from Sichuan and Guangxi was（9.01±1.05）and （8.35±0.84）μg RT/g DW，respectively.The orientin and vitexin contents in P.edulis Sims peel from Sichuan were（0.79±0.05）μg OR/g DW and（0.16±0.01）μg VI/g DW，repextively，and there was no significant difference in orientin and vitexin contents between Fujian and Guangxi.Some differences were observed in the antioxidant activities of the P.edulis Sims peel among the three areas，and the antioxidant activity from high to low was Sichuan > Guangxi > Fujian.Correlation analysis indicated that the total phenolic content and rutin content in P.edulis Sims peel were significantly correlated with the antioxidant activities.Taken together，P.edulis Sims peel was a high quality source of phenolic compounds，but the phenolic compounds and antioxidant activities were different in the three producing areas.In the future，P.edulis Sims peel from different producing areas can be developed as needed to achieve precise utilization.
