Phytochemical parameters and antioxidant activity of new cherry silverberry biotypes (Elaeagnus multiflora Thunb.)

Abstract

This paper analyses the phytochemical composition, and antioxidant activity of new selected biotypes of cherry silverberry grown in Poland. In addition, the polyphenolic contents, sugars, and vitamin C, as well as organic acid profile were evaluated. Among the researched compounds, two sugars, seven organic acids, and six fatty acids were reported in new studied biotypes of cherry silverberry. Some new biotypes presented a high contents of vitamin C, linoleic, α-linoleic acids (si1, and si2), glucose, fructose, ash (si5, and si4), other fatty acids, organic acids, and antioxidant activity (si0, and si3). They displayed an average contents of polyphenols [5.68 g GAE/100 g dry matter (d.m.)], vitamin C (15.13 mg/100 g), ash (0.56%), fatty acids (89.99%), organic acids (22.41 g/100 g d.m.), sugars (47.96 g/100 g d.m.), and high antioxidant activity of 3.62 mM Trolox (TE)/100 g d.m. (FRAP assay), and 5.11 mM TE/100 g d.m. (DPPH assay). The new biotypes of cherry silverberry cultivated in Poland might be a good source for the production of functional foods, and direct consumption. Moreover, cherry silverberry is an inquisitive material with a different phytochemical components, and according to the principal component analysis, strongly dependent on the biotype.

In Vitro Biological Activities of Fruits and Leaves of Elaeagnus multiflora Thunb. and Their Isoprenoids and Polyphenolics Profile

“…Fruits of this species, being suitable for direct consumption and processing, have been ascribed health-promoting properties [2,3]. Today, this species is grown in the eastern part of the United States and in Europe, including Poland, as not only an ornamental plant but also a plant usable for homemade processing [4,5]. As demonstrated in the study conducted by Bieniek et al [4], this plant grows very well in the moderate climate of Poland and is characterized by the ease of cultivation and resistance to diseases.…”

Distribution of Polyphenolic and Isoprenoid Compounds and Biological Activity Differences between in the Fruit Skin + Pulp, Seeds, and Leaves of New Biotypes of Elaeagnusmultiflora Thunb

“…All plants were planted with 4 × 2 m 2 spacing in Albic Luvisolx (Arenic) soil, which was deeply flattened and produced from clays of pH 6.8 in KCl [5]. The shrubs started to fructify in the third year after planting.…”

“…After 10 min of reaction, absorbance was measured at 734 nm for ABTS and 593 nm for FRAP. Determinations by ABTS and FRAP methods were performed using a UV-2401 PC spectrophotometer (Shimadzu, Kyoto, Japan) [5]. All antioxidant assays were performed in triplicate and expressed as mmol of TE per 100 g d.w.…”

“…Only 14 compounds belonging to phenolic acids and flavan-3-ols have been identified so far [3]. Polyphenols are important compounds due to their beneficial effects, including anticarcinogenic, antiinflammatory, antioxidant, antitumor, and antidiabetic, as well as anti-atherosclerotic, activities [4,5]. In addition, they are the focus of interest in the food industry due to their high nutritive value [3].…”

“…The accumulation of polyphenolic, terpenoid, or polysaccharide compounds in a plant can be effective only upon sufficient access of light, phosphorus content in the soil, and-last but not least-soil organic matter [8]. As demonstrated by Lachowicz et al [5], contents of the basic physicochemical compounds were significantly affected by the novel cultivars analyzed. In addition, these cultivars can be excellent components of health-promoting and other beneficial products intended for human consumption (functional foods, nutraceuticals, supplements, nutricosmetics, etc.)…”
