Phenolic compounds, bioactive content and antioxidant capacity of the fruits of mulberry (Morus spp.) germplasm in Turkey

Abstract

The study was carried out in 2014 and 2015, and aimed to determine some important biochemical and antioxidant characteristics of the fruits of mulberry (Morus spp.) cultivars and genotypes found in Malatya (Turkey). Phenolic compounds (protocatechuic acid, vanillic acid, ellagic acid, rutin, quercetin, gallic acid, catechin, chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, o-coumaric acid, phloridzin and ferulic acid), organic acids, sugars, vitamin C and antioxidant capacity were analyzed in sampled fruits. The results showed that most of the biochemical content and antioxidant capacities of the cultivars and genotypes were significantly different from one another (p < 0.05). Among the phenolic compounds, rutin (118.23 mg 100 g ) were determined to have the highest values for most of the fruit samples. Malic acid and citric acid were dominant among the organic acids for all the cultivars and genotypes except 44-Nrk-05. Glucose was measured as a more abundant sugar than fructose and sucrose in all samples. Antioxidant capacity, on the other hand, varied between 6.17 and 21.13 µmol TE g -1 among the cultivars and genotypes analyzed.Ke y wor d s: cultivar, genotype, mulberry, phytochemicals

The optimization of extraction process of white mulberry leaves and the characteristic bioactive properties its powder extract

“…Dry mulberry leaves exhibited DPPH radical scavenging activity as 18.1 mg TE/g DM. This agrees with a recent study of Sánchez-Salcedo et al [25] showing slightly lower radical scavenging activity amounting till 12.64 mg TxE/g DW. The water extraction process caused more than fivefold increase of antioxidant activity.…”

Phenolic compounds and phytochemicals in fruits of black mulberry (Morus nigra L.) genotypes from the Aegean region in Turkey

“…Sugar content of mulberry genotypes (mean for 2016 and 2017 ±SE) Genotypes Glucose (g 100 g -1 ) Fructose (g 100 g -1 ) Sucrose (g 100 g -1 ) 64USA01 9.13 ±0.16 b* 6.54 ±0.12 e 1.51 ±0.03 c same study, citric acid, tartaric acid, succinic acid and fumaric acid contents were found to range from 0.48 to 1.03 g 100 g -1 , 0.15 to 0.43 g 100 g -1 , 0.12 to 0.44 g 100 g -1 , and 0.01 to 0.12 g 100 g -1 , respectively. Gundogdu et al (2017) found caffeic acid (21.09-2.44 mg 100 g -1 ), syringic acid (11.91 -1.16 mg 100 g -1 ), and p-coumaric acid (5.67-0.70 mg 100 g -1 ). In this study, it was determined that the genotypes 64USA01, 64USA07, 64USA08, 64USA10 showed desirable features when compared to other genotypes in terms of phenolic compounds.…”

“…The Morus nigra L. species exists almost everywhere in Anatolia and is represented by wildelderly trees (Gundogdu et al, 2017). The height of mulberry trees is 3-15 m, and they have a splayed, rounded, clustered crown structure.…”

Phenolic profiles and antioxidant capacities of mulberry ( Morus atropurpurea Roxb.) juices from different cultivars

“…Species within each of these three states are important genetic sources of biodiversity, which support the diverse array of life on earth. [1][2][3][4][5] Wild black mulberry is a valuable resource in medicinal chemistry, gaining importance for its potential to prevent and treat diseases. [6] Mulberry (Morus, Moraceae) grows across an extensive range of climatic, topographical, and soil conditions.…”
