Features of Microelements and Low-Molecular Weigh Antioxidants Accumulation in Plants Ofthe Genus Rosa L.

Abstract

Wild roses are an important group of plants used as row material for pharmaceutical, cosmetic and food industries. The aim of this study was to determine the microelements (Mn, Fe, Zn, Cu, Cr, Ni, Pb, Co, Cd) content and distribution in the aboveground and underground parts of the Rosa acicularis, R. davurica, R. rugosa, growing in Baikal region. It was found that R. rugosa plants are characterized by a higher Cu content and a low level of Mn; the hips of these plants also accumulate Fe, Zn, and Co. In the sepals, leaves, stems and roots of R. davurica the highest concentrations of Fe are noted, and in the vegetative and generative organs of R. acicularis – Cr. Transport of Zn, Cu, Ni in aboveground parts of plants is mainly acropetal, the remaining elements translocation in basipetal direction. Cd belongs to the elements of strong accumulation in plants of all three species, in addition, species-specific features of some elements accumulation in aboveground and underground organs are revealed. It was found that the fruits, leaves, and stems of Rosa acicularis and Rosa rugosa can serve as a potential source of Mn, Cr, and Co.

Soil quality Change Following Compost and Farmyard Manure Application in Maize and Cassava based Agro-ecosystems of Mvomero and Masasi -Tanzania

“…It was found that R. rugosa (growing in Baikal region) plants are characterized by a higher Cu content and a low level of Mn; the hips of these plants also accumulate Fe, Zn, and Co in the sepals, leaves, stems and roots. It has been shown that rose hips, as well as the leaves and stems of Rosa rugosa, can serve as a potential source of Mn, Cr, and Co for the human body [85]…”

Developing a New Collagen Peptide Serum Containing Gold Nanoparticles for Cosmetic Purposes

“…Typically, compounds such as citric acid and sodium borohydride, which can be toxic, are employed in the reduction process. However, recent studies have explored alternative methods, utilizing extracts from natural sources such as honey, polysaccharides, microorganisms, and plants like Rosa rugosa, Terminalia catappa, and Zingiber officinale for gold nanoparticle synthesis [5][6][7][8]. Interestingly, the concentration of the reducing agents in these methods has been shown to influence the size and shape of the resulting nanoparticles.…”
