Highest content was located for glucuronic acid (21.98 ), galacturonic acid (16.28 ), and glyceric acid (14.76 ). Glucuronic and galacturonic acids are the most abundant sugar acids in the WZ8040 Autophagy tested SE fruit extract, as they are the important components of plant polysaccharides, like cellulose and pectin. three.1.four. Saccharides Literature data offer data mostly about glucose and sucrose content in SE fruit extracts [13]. We report new data relating to the saccharide content material of SE fruit extract: the monosaccharides comprise 64.12 (263.61 /mL), followed by disaccharides 26.51 (108.98 /mL), and trisaccharides (primarily raffinose) 9.37 (38.52 /mL). Other identified monosaccharides have been fructose, fructose-6-phosphate, arabinose, xylose, and mannose-6-phosphate. Disaccharides were presented by melibiose and trehalose at the same time.Plants 2021, 10,16 of3.1.5. Fatty Acids and Fatty Esters Data regarding the lipid composition of SE fruits are very limited. Most studies identified 4 sterols in SE fruit extract: brassicasterol, campesterol, stigmasterol, sitosterol [11,12]. In our samples, -sitosterol (15.22 /mL) was the only sterol we detected. The newly identified fatty esters incorporated 1-monopalmitin and monooctadecanoylglycerol. Other authors offer data concerning the presence of octadecanoic and octadecadienoic acids too as palmitic, octadecenoic, dehydroabietic, oleic, oleanolic, ursolic, and maslinic acid [12]. We found the highest volume of any fatty acid for octadecadienoic acid (15.65 .41 /mL) comprising 18.41 of all fatty acids (84.98 /mL), and 5 newly identified fatty acid (hexadecenoic, heptadecanoic, hexadecatrienoic, hexadecanoic and octadecatrienoic). Oleanolic, ursolic, and maslinic acid are pentacyclic triterpenes recognized to possess anticancer properties [42,43]. Ursolic acid, particularly, reduces SBP-3264 Purity LPS-stimulated NFB signaling [44], inflammatory cytokine production by inhibition JNK signaling [45], ER tension induced by higher fat eating plan, and NFB associated inflammation [46]. It’s assumed that ursolic acid may also improve insulin sensitivity [47,48]. In our previous study on healthy volunteers we reported that SE fruit tea intake improves lipid profiles, minimizing total and LDL cholesterol serum levels and improving volunteers’ HDL/LDL ratios [22]. The intake of phytosterols including -sitosterol may possibly reduce total serum cholesterol [49] and low-density cholesterol [50]. As brassicasterol, campesterol [11] and -sitosterol are among the phytosterols with known cholesterol-lowering activity [513], it is not surprisingly that SE fruit tea exerts a cholesterol-lowering effect. 3.1.6. Phenolic Compounds Compared with other species of the Sambucus genus, for example S. nigra, S. cerulea, and S. racemose, S. ebulus would be the richest in total hydroxycinnamic acids, catechin, epicatechin and flavonols [15]. Anthocyanins are the predominant colored polyphenols in elderberries. In our study we identified three new anthocyanins: cyanidin-3-O-galactoside (the main anthocyanin in most plants), cyanidin-3-O-arabinoside and cyanidin-3-O-xyloside. In accordance with other studies, we also found in our samples cyanidin-3-O-glucoside, but not cyaniding-3O-sambubioside [14]. Anthocyanins exerts several useful health effects including antioxidant, anti-inflammatory, anticancer, antidiabetic, anti-toxic, cardiovascular and nerve-protective capacities [54]. Flavanols, like catechin and epicatechin, have been previously reported in SE fruits [15,16], as had been.
