“…Extracts of fruit, leaf, root and stem bark of the plant are used to treat various ailments such as cough, diarrhea, skin infections, jaundice, snake bites, chest diseases, cold, dysentery, stomach disorders, lactation disorders, liver disease, epilepsy, tuberculosis, helminthiasis, infertility, and diabetes mellitus [5,6]. Constantly developing technology, environmental pollution, contaminated waters, radiation, heavy metals, pesticides and oxygen metabolism in living cells cause the formation of free radicals in the human body [7]. Free radicals are known to cause many diseases, particularly cancer.…”

Objective: The aim of this study was to determine the antioxidant and antimicrobial activity of Ficus sycomorus fruit and leaf extracts obtained from the Turkish Republic of Northern Cyprus. Materials and Methods: Fruits and leaves of F. sycomorus were collected from the Kyrenia region of Northern Cyprus in July 2018. The leaf and fruit samples were extracted with the distilled water, methanol, ethanol, acetone and chloroform solvents (1:10 [w/v]). After evaporation, samples were suspended in methanol at the final concentration of 100 mg/mL. The antimicrobial activity of the leaf and fruit extracts was evaluated using the Kirby-Bauer Disk Diffusion Method. Total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were determined using the methods reported by Stankovic in 2011 and Sharm and Vig in 2013. Antioxidant activity of samples was tested using free radical scavenger method. Results: The leaf extracts of F. sycomorus was active. The inhibition zone diameters ranged from 1.8mm to 13.00 mm. Fruit extracts and methanol controls showed no inhibitory effect on strains. However, bacteriostatic activity against Enterococcus faecalis was observed in fruit-water extract. The highest antimicrobial activity was shown against Staphylococcus aureus (13 mm) for ethanolic extracts at 100 mg/mL concentration. Minimal inhibition concentration (MIC) for ethanolic extract was observed starting at 25 mg/mL concentration against S. aureus. Although, no antimicrobial activiy was observed in fruit extracts, the highest 2,2-diphenyl 1-picrylhydrazyl (DPPH) activiy and phytochemical content were recorded in fruit extracts. Conclusion: These results demonstrate that leaf extracts of F. sycomorus can be used as a curative agent for the treatment of S. aureus and fungal infections and may be effective against pathogenic microorganisms that are resistant to antibiotics. Antioxidant content of fruit and leaf extracts can be effective against the negative effects of free radicals.

“…Therefore, it has a high antioxidative capacity (Amodio et al, 2007). It is accepted that the consumption of foods with high antioxidant capacity has a positive effect on health by reducing oxidative stress (Kasnak and Palamutoğlu, 2015). Antioxidant activity can be determined using certain radicals such as 2,2diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) or can be estimated because it correlates with total phenolic and ascorbic acid contents (Moharram and Youssef, 2014).…”

The study aims to determine the extraction parameters for maximal phenolic compounds and antioxidant activity from kiwifruit by using response surface methodology (RSM). Box-Behnken experimental design of RSM was applied to determine the effect of extraction parameters. Three independent variables were selected at three levels: methanol concentration (A: 60-75-90 %), ultrasound time (B: 5-10-15 min.), and mass of sample (C: 1-2-3 g). Conditions for maximum phenolic yield were found as A = 90%, B= 7.71 min, and C = 3 g, under this condition, DPPH of 88.96 %, ABTS of 739.07 mg/100g FW and TPC of 299.14 mg/100g fresh weight has been obtained.

“…Gıdalardaki antioksidanlar insan sağlığı üzerine olumsuz etki yapan serbest radikalleri azaltan ya da yok eden maddelerdir [20]. Ayrıca, antioksidanlar anormal hücre çoğalmalarını önleyip, oksidasyondan dolayı zarar gören hücreleri de onarmaktadırlar [21]. Meyvelerin antioksidan içerikleri arasındaki bu farklılıklara çeşitlerin genetik özellikleri, hasat zamanı, ekoloji, depolama süresi ve depolama koşullarının etki edebileceği düşünülmektedir [22].…”

Hosui ve Kosui Asya armut çeşitlerinin gelişme, verim ve meyve kalite özellikleri incelenmiştir. Çeşitlerin gövde gelişme düzeyleri 11.73 cm 2 (Hosui) -24.03 cm 2 (Kosui); taç gelişme düzeyleri ise 1.13 m 3 (Hosui) -25.60 m 3 (Kosui) arasında belirlenmiştir. En erken çiçeklenme Kosui'de (30 Mart) en geç ise Atago'da (02 Nisan) gerçekleşmiştir. Çeşitlerin hasatları 22 Ağustos (Hosui) -21 Eylül (Chojuro) tarihleri arasında yapılmıştır. Ağaç başına verim bakımından Atago çeşidi (37.39 kg/ağaç) en verimli bulunmuştur. Çeşitlerin meyve ağırlıkları 113.44 g (Hosui) -326.40 g (Chojuro); meyve sertlikleri 13.97 lb (Hosui) -16.91 lb (Chojuro); suda çözünebilir kuru madde miktarları (SÇKM) % 11.60 (Atago) -% 14.20 (Hosui) ve titre edilebilir asitlik değerleri 0.10 g/100 ml (Hosui) -0.26 g/100 ml (Atago) arasında saptanmıştır. Hosui en parlak (L*67.53) ve en koyu sarı (b* 38.91), Chojuro (a* 13.65) en kırmızı meyveleri oluşturmuştur. Toplam antioksidan değerleri 0.663 (Kosui) -1.086 (Chojuro) µm/g arasında olduğu tespit edilmiştir. Çeşitlerde oksalik asit, süksinik asit ve malik asit diğer organik asitlere göre en yüksek değerleri vermiştir.
