The method of spectral identification of hips and vitamin collection
The invention relates to the chemical and pharmaceutical industry and to a method for the identification of medicinal plant substances - rose hips and vitamin collection № 1 by analyzing the spectral characteristics of alcohol extraction. The method of identification of hips and vitamin collection № 1 includes obtaining alcoholic extract using ethanol with a concentration of 95%, an aliquot of 5-8 ml is placed in a 25 ml volumetric flask, add 5-8 ml of acetic acid 30%, 8 ml of alcohol 2% solution of aluminum chloride, bring 95% ethanol to the mark (pH of the solution 1.6 ± 0.4) and remove the spectrum against the background of a reference solution consisting of 5-8 ml of alcohol extraction and 8 ml of acetic acid 30% brought to the mark 95% ethanol; at the same time, three absorption maxima are simultaneously detected on the absorption spectrum, corresponding to: phenol carboxylic acids at 311 nm for vitamin collection № 1 and 323 nm for rose hips; flavonoids at 411 nm for vitamin collection № 1 and 404 nm for rose hips; anthocyanins at 540 nm for vitamin collection № 1 and 526 nm for rosehips.
The project to develop a cellular model of the placenta became the winner in the Scientific Materials category of the Young Scientists 3.0 competition, organized with the support of the Presidential Grants Foundation and T-Bank.
Ten scientific journals published by RUDN University have been included in the highest level of the state list of scientific publications, the White List.
Forests are not only the lungs of the planet, but also home to millions of species. However, it has remained unclear how underground interactions between trees and fungi affect forest species richness in different climatic conditions. Previous studies have yielded conflicting results: in some regions, the dominance of certain fungi reduced tree diversity, while in others it increased it.
