Abstract

This study was carried out to determine the bioactive compounds of superior medlar genotypes grown in Terme district (Samsun province in the Black Sea region of Northern Turkey) in 2017 and 2018. In the genotypes, the ascorbic acid varied from 24.6 mg 100 g-1 to 35.1 mg 100 g-1; organic acid contents (citric, malic, succinic) from 2.4 mg 100 g-1 to 13.0 mg 100 g-1, from 576.5 mg 100 g-1 to 707.4 mg 100 g-1, from 111.9 mg 100 g-1 to 188.5 mg 100 g-1, respectively; sugar contents (sucrose, glucose, fructose) from 111.9 mg 100 g-1 to 227.4 mg 100 g-1, from 2226.9 mg 100 g-1 to 2955.5 mg 100 g-1, from 3530.7 mg 100 g-1 to 4740.8 mg /100 g-1, respectively; the total phenol content from 24.0 mg GAE 100 g-1 to 107.4 mg GAE 100 g-1 and antioxidant activity from 9.1 mmol TE 100 g-1 to 50 mmol TE 100 g-1. It can be said that some genotypes are remarkable in terms of total phenolic, antioxidant activity and ascorbic acid contents.
