“…The minerals content of WML-P is in Table 1D. Among minerals, Ca and Mg were present in the highest amounts and were similar to those found in Thai and Serbian WML [39,40]. Content of Fe and Mn, cofactors of many enzymes, including catalase in photosynthetic cells, did not change after conditioning.…”

This study evaluated the effect of adding a new step, termed conditioning, to the traditional processing of leaves from Morus alba var. zolwinska wielkolistna grown in Poland (WML-P). This step, modeled on tea leaves processing, was conducted in a controlled environment on a semi-technical scale. The primary goal was to evaluate the effect of the WML-P conditioning for 1–4 h at 32–35 °C on the content of bioactive compounds (total phenolics, phenolic acids, flavonols, 1-deoxynojirimycin) and antioxidant activity (radical scavenging against DPPH, antioxidant capacity, chelating activity and ferric reducing antioxidant potential) of the lyophilized extracts. For the first time WML-P extracts content was comprehensively characterized by assessing dietary fiber fractions, fatty acids, amino acids, macro- and microelements and chlorophyll content. Compared to the traditional process, adding the conditioning step to WML-P processing resulted in an increased total phenolics content, radical scavenging capacity, ability to quench 2,2-diphenyl-1-picrylhydrazyl (DPPH•) and iron-chelating ability in the lyophilized extracts. The beneficial effect depended on conditioning time. The highest flavonols and phenolic acids content were found after 2-h conditioning. We concluded that adding a 2-h conditioning step to traditional WML-P processing results in getting WML-P lyophilized extract with increased bioactive compounds content and high antioxidant activity.

The present study aimed to evaluate chemical and biological potential of aronia stems for providing new raw material for food and pharmaceutical industries. Aqueous extracts of aronia stems were prepared by three different techniques (microwave-assisted, ultrasoundassisted and subcritical water extraction). For biological activities, antioxidant, antimicrobial and cytotoxic activities were evaluated. For chemical characterisation, phenolic compounds and essential elements were analysed as well as total phenolic contents. Subcritical water extracts exhibited the strongest antioxidant activity with the highest content of phenolics. Minimum inhibitory concentrations for analysed extracts were in the range from 9.76 to 156.25 μg/mL in antimicrobial assays. The extracts exerted prominent cytotoxicity against different cell lines. Rutin was detected as the major compound in the studied extracts and these extracts were also rich in essential elements. Our study suggested that subcritical water extract of aronia stem could be considered as a new raw material in developing novel functional/industrial products.

“…Noordulin et al (2015) described that different mulberry genotypes and harvest time also influenced the calcium content. Other scientists have also confirmed the dependence of Ca levels on the characteristics of a cultivar (Radojković et al, 2014).…”

“…They discovered that the Mg content significantly increased with maturity. According to Radojković et al (2014), the first macroelement found in the extract of the M. alba and M. nigra leaves was Mg and the second was Ca. The increasing trend of Ca and Mg with the age of the leaf could be attributed to a limited mobility of these elements in the phloem (Leece, Gilmour, 1974).…”

“…Mineral elements play important roles in biological reactions and have structural functions. The mulberry leaves contain a variety of nutrients, including macroelements (Radojković et al, 2014;Srivastava et al, 2006). As reported by many authors, the chemical contents of plant (mulberry) leaves are influenced by many factors, such as genetics, environment, climatic conditions, irrigation, fertilizing and soil conditions (Chetri et al, 1999).…”

The aim of this study was to evaluate the agrochemical and biological quality indicators of soil and to determine the best harvest time to maximize the nutrient contents of white mulberry leaves (Morus alba L.) from two different cultivars. Mulberry leaves were analysed to determine the seasonal changes in the contents of Ca, K, P, Mg and S. The study was carried out on 7-year-old mulberry trees belonging to Morus alba L. cultivated in an organic farm in the Kaunas District of Lithuania in 2016 and 2017. The soil agrochemical and biological indicators and mulberry leave samples were analysed two times during the tree vegetation period. The soil samples were collected in May and September (in the 2nd ten-day period) and leaves in June and September (in the 2nd ten-day period). The study revealed that a decreasing tendency for soil agrochemical indicators was observed throughout the entire period of growth of mulberry trees. At the end of the vegetation period the contents of nitrogen, available phosphorus and available potassium significantly decreased by 7.93, 24.85 and 25%, respectively, compared with that taken in May. At the end of the mulberry tree vegetation period the microbial biomass and dehydrogenase activity in the soil significantly decreased, by 20.39 and 17.95%, respectively, compared with that taken in the beginning of the vegetation period. The study revealed that harvest months had a statistically significant impact on the levels of the examined elements among the two Morus cultivars. It was found that the main macroelement in the leaves of both cultivars was Ca followed by K, P, Mg and S. However, the highest Ca, Mg, P and S contents in ‘Turchanka’ leaves increased with maturity. Importantly, the amount of macronutrients in the mulberry leaves varied in accordance with the cultivar and the harvest time. These results can help farmers to select a cultivar and harvest time that would allow them to produce mulberry leaves with superior quality. Leaves collected from mulberry plants grown in Lithuania plantations may be used as a food supplement to help meet the recommended daily intakes of some macrominerals for adults.
