Potential Nutritional Value of the Macrophyte Vossia cuspidata (Roxb.) Griff. (Poaceae) in a River Nile System, Egypt

Abstract

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ A QUATIC plants are of real interest for their nutritive value. The present study aimed at investigating the forage potentiality of the aquatic macrophyte Vossia cuspidata (Roxb.) Griff (Poaceae). Two islands in the River Nile system in Greater Cairo, Egypt were selected for sampling the leaf laminae from V. cuspidata in eighteen quadrates (0.5x 0.5m each) during February (winter), and August (summer) of 2017. The chemical analyses revealed that there were no significant differences between the contents of summer and winter leaves in their percentages of moisture, dry matter, ash, nitrogen-free extract, neutral detergent fibers, acid detergent fibers, acid detergent lignin, cellulose, and hemicellulose. The leaves were characterized by a high percentage of dry matter (DM, ≈ 92%), low moisture content (7.94-7.27% DM), high crude fibers (24.1-38.2%DM), moderate crude protein (7.2=19.2%), and low lipids content (1.7-2.0% DM). The plant is rich in many important elements (K, Ca, P, Cu, and Zn). The ratio of Ca/P (= 2.43) is within the adequate range for animal forage. The other parameters of the nutritive values of the leaves and their importance to animal feeding were discussed. The leaves of V. cuspidata are recommended as good forage for beef cattle and lactating cows.

The Activity of Vossia cuspidata Polysaccharides-Derived Monometallic CuO, Ag, Au, and Trimetallic CuO-Ag-Au Nanoparticles Against Cancer, Inflammation, and Wound Healing

“…In all spectra, the bands at 3500-3200 cm −1 were assigned to O-H stretching vibration, the bands at 2850-3000 were assigned to C-H stretching, 1700-1850 cm −1 bands were assigned to the carbonyl group, 1600-1650 cm −1 alkenyl aliphatic C=C stretch, 1400-1600 cm −1 -alkenyl aromatic C=C stretch, 1350-1401.73 cm −1 (C-H bending), vibration at 1078.26-1300 cm −1 -C-O group [30][31][32]. The biomolecules in the PS extract converted metal ions into metal NPs, resulting in nanoparticle stability and a decrease in bands [33] as presented in Fig. 2b.…”

“…Vossia cuspidata (Hippo grass in English) is a perennial emergent macrophyte of the Poaceae family [28]. Although the plant is rarely studied in its distribution areas, it is a promising forage and medicinal plant that has many important constituents such as proteins, carbohydrates, glucosides, alkaloids, terpenoids, and flavonoids, in addition to a valuable essential oil [29][30][31][32][33]. The biosynthesis of CuO/ Ag/ Au monometallic and CuO-Ag-Au trimetallic nanoparticles using the extracted PS of V. cuspidata leaves was not yet reported.…”
