Abstract

Medlar (Mespilus germanica L) grows wildly in East Azerbaijan province (Arasbaran). Unfortunately, a few studies have been done on medlar in this area, except in limited cases. This research was conducted based on factorial experiment in completely randomized design with three replications. In this research, the Phenolic compounds and antioxidant activity of the peel and pulp of medlar fruit were measured. Also, the extraction Solvents were methanol (85%) and acetone (80%). The results showed that the methanolic extracts had the highest total Flavonoid (415. 00 and 327. 83 mg CE. 100g FW) and total tannin (1132. 67 and 1575. 33 mg CE. 100g FW) in the both of peel and pulp, respectively. Also, the peel antioxidant activity using FRAP method in methanol and acetone Solvents was 1. 17 and 1. 13 mg Fe2(SO4)g FW, respectively, which showed no significant difference at 5% probability level. The highest total phenol (762. 51 and 526. 12 mg GAE. 100g FW) total non-Flavonoid (427. 01 and 365. 46 mg CE. 100g FW) in the both of peel and pulp and antioxidant activity based on DPPH and Fe2+chelating methods (94. 87% and 52. 31%) and antioxidant Composite index in the peel of fruit (98. 86) was obtained in acetonic extracts. In general, the results indicated that medlar fruit are a potential source of natural antioxidants in the part of peel and pulp, and acetone is the best Solvent for the extraction of compounds containing antioxidant activity.
