“…The total phenolic contents of the fruits of 15 medlar genotypes varied between 41 mg GAE 100 g −1 in Ton-9 genotype and 411 mg GAE 100 g −1 in Ton-20 genotype, and The difference of glucose content compared to genotypes was insignificant (Table 4). The total phenolic content of the Medlar genotypes in this study was found to be higher than in some previous studies carried in different regions of Turkey, and this value ranged from 9.0 to 293.0 mg GAE 100 g −1 in the other studies (Ercisli et al, 2012;Akbulut et al, 2016;Yılmaz et al, 2016;Akın and Bostan, 2018;Maral and Bostan, 2020). Rop et al (2011) determined that the total phenolic content in the fruit gradually decreased after the full bloom in Medlar and decreased to 145 mg GAE 100 g-1 on the 154th day, and 93 mg GAE 100 g-1 on the 164th day; Selcuk and Erkan (2015) stated that the total phenolic content in the medlar decreased with storage time and that the initial value of 763.03 mg GAE 100 g −1 decreased to 81.15 mg GAE 100 g −1 after 60 days.…”

“…Ascorbic acid within the studied genotypes was ranged from 21.5 mg 100 g −1 (Ton-10) to 44.2 mg 100 g −1 (Ton-9) (Table 2). The content of ascorbic acid in different Medlar genotypes was reported to be of 2.64-87.20 mg 100 g −1 (Akbulut et al, 2016;Akın and Bostan, 2018;Duman, 2019;Ercisli et al, 2012;Glew et al, 2003aGlew et al, , 2003bMaral and Bostan, 2020;Özkan et al, 1997;Ozturk et al, 2019;Pető et al, 2016;Rop et al, 2011;Sarıyıldız, 2019;Selcuk and Erkan, 2015;Vargas et al, 2009;Waźbińska, 2007;Yılmaz et al, 2016) in different agroecological conditions of Turkey and other countries. Differences in ascorbic acid contents could result from the variations in genotypes, variety, ecological factors, years and harvesting period.…”

“…There is large diversity in terms of fruit color, shape and taste in the cultivars and genotypes (Özbek, 1978). Indeed, a few previous studies (Akbulut et al, 2016;Akın and Bostan, 2018;Aygün and Taşçı, 2013;Bostan, 2002;Bostan and İslam, 2007;Duman, 2019;Ercişli et al, 2012;Közen and Bostan, 2016;Maral and Bostan, 2020;Özkan et al, 1997;Sarıyıldız, 2019;Uzun and Bostan, 2019;Yılmaz, 2015;Yılmaz and Gerçekcioğlu, 2013;Yılmaz et al, 2016) have also revealed the diversity of fruit traits and potential of Medlar genetic resources in Turkey. The Black Sea region of Turkey is the place where Medlar is grown common.…”

“…Fruit are very rich sources of bioactive compounds such as phenolics, and also be of different fatty acids (Seçilmiş Canbay et al, 2015), and polyphenol oxidase activity in Medlar fruit is considerably higher than that found in many other fruit species (Akçay et al, 2016). In addition, Medlar is a good source of natural antioxidants, and has potential of use in food and nutraceutical supplement formulations (Akbulut et al, 2016).…”

The Black Sea region of Turkey is where the Medlar population is most common, and Medlar usually grows naturally in this region. This study was carried out to determine the organic acids, sugars and bioactive compounds of promising Medlar (Mespilus germanica L.) genotypes which were grown in Tonya and Sürmene districts of Trabzon province (Black Sea Region of Turkey) in 2017 and 2018. Total of 15 genotypes were evaluated in the study, including 8 genotypes from Sürmene and 7 genotypes from Tonya. As a result, crude protein was ranged from 1.65 to 2.70%, crude oil from 0.10% to 9.40%, soluble solids contents from 9.80% to 20.20%, titratable aciditty from 0.60% to 1.40%, ascorbic acid from 21.5 mg 100 g −1 to 44.2 mg 100 g −1 , malic acid from 590.5 mg 100 g −1 to 1074.5 mg 100 g −1 , succinic acid from 127.0 mg 100 g −1 to 419.0 mg 100 g −1 , and citric acid from 2.0 mg 100 g −1 to 32.0 mg 100 g −1 , fructose from 3255 mg 100 g −1 to 4726 mg 100 g −1 , glucose from 2108 mg 100 g −1 to 3017 mg 100 g −1 , sucrose from 127 mg 100 g −1 to 399 mg 100 g −1 , carbohydrate from 47.3% to 73.1%, total phenolics from 41 mg GAE 100 g −1 to 411 mg GAE 100 g −1 and antioxidant activity 13.1 mmol TE 100 g −1 to 77.8 mmol TE 100 g −1 . It was found large diversity regarding crude oil, SSC, titratable acidity, citric acid, glucose and antioxidant capacity of fruits among the genotypes. It can be said that the fresh fruits of promising Medlar genotypes are particularly promising for the use of nutraceuticals. In particular, Ton-20 and Ton-21 genotypes were remarkable due to their high-quality characteristics and total phenolic content.

“…It is indigenous in southeastern Europe, Anatolia, Crimea, Caucasia and the northern parts of Iraq and Iran. In Turkey, 4352 tons of medlar were harvested in 2017 according to Turkish Statistical Institute (Akbulut et al, 2016, TUIK, 2018. Medlar is a potential source of ascorbic acid and natural antioxidants as well as including phenolics like chlorogenic acid, rutin and p-coumaric acid.…”

The effects of microwave (90 W and 180 W), hot air (60 and 70°C) and vacuum (60 and 70°C with 200 and 300 mbar) drying methods on drying characteristics, total phenolic content, antioxidant capacity, color and in vitro gastrointestinal digestion of medlar pestil were investigated. Medlar showed a good potential for pestil production while being the most applicable in microwave treatments. For drying kinetics, five thin-layer drying models were applied and the Page and Modified Page were the best fitted models. L*, b*, chroma and hue angle decreased while a* generally increased in dried pestils. Dried samples showed a general decrement in phenolics and antioxidant capacity. According to in vitro gastrointestinal digestion, intestinal phase of all the samples resulted with an increment in phenolics, FRAP and DPPH compared to undigested extracts. In conclusion, different drying methods may affect the release of phenolics and antioxidant capacity, while leading to increased bioaccessibility during intestinal digestion.

Medlar (Mespilus) is an important fruit and is rich in nutritional and medical properties. Bioactive content and phenolic compounds of leaf, fruit, and seed samples of common medlar (M. germanica) and Stern’s medlar (M. canescens) were studied. The coefficient of variation showed high values among all the characters and was more than 50.00%, ranging from 59.74 to 196.81%. The leaf of M. canescens showed the highest total phenolic content (14.73 mg/g dry weight, DW) and followed by 13.70 mg/g DW in the seed of M. germanica collected from Ilam province, Iran. The highest flavonoid content was observed in fruits of M. germanica collected from the north of Iran (0.90 mg/g DW), and followed by the leaf of M. canescens (0.53 mg/g DW). The phenolic compounds showed strong variation. Principal component analysis showed that four PCs explained 95.07% of the observed total variance. Ward dendrogram indicated two different clusters based on the characters measured, indicating high variation among the accessions. The current investigation clearly showed the potential value of the common medlar (M. germanica) and Stern’s medlar (M. canescens) germplasm, as different medlar organs are significant sources of phenolic compounds and high antioxidant activity. Therefore, these species can be considered suitable sources of natural antioxidants, and may show potential future use in food and nutraceutical supplement formulations.
