THE POSSIBILITY OF USE OF EXTRACTS FROM HIGHER HYDROPHYTES AND GEOPHYTES OF THE ASTRAKHAN REGION FOR THE NEEDS OF COSMETOLOGY - Biochemistry and Biotechnology: Research and Development - page 150

At this stage of the experiment is carried out the selection of individual components of
the studied extracts of higher water plants of the Volga river and terrestrial plants of the
Astrakhan region, and planned their integrated use in the preparation of cosmetic products for
various purposes.
3. R ESULTS
The results of experiments to determine the chemical and carbohydrate composition
suggest that the water content in air-dry plant pondweed Potamogeton perfoliatus L. is about
9.3 %. Dry matter freshwater grass (90.7 %) consists of organic materials: ash (20.4 %), crude
protein, soluble and insoluble carbohydrates.
As part of perfoliate pondweed contains large amounts of carbohydrates, including in
particular tissue - 19.7 %, and pectin - 18.4 %, as well as easily-hydrolysable and soluble
carbohydrates in an amount of 11.2 % and 9.6 % respectively. Contents in the ether-soluble
substances is about 1.7 % of total nitrogen in dry matter is negligible (7.5 %).
Thus, high levels of carbohydrates and minerals, as well as microbiological safety
perfoliate pondweed indicates the possibility of using water plants as raw material for extracts
[16].
Research activity of extracts of these plants in the experiments show a direct effect on the
suspension of Staphylococcus aureus in culture.
Highest antimicrobial activity against a Staphylococcus aureus , isolated from the external
environment, have kidney extracts of black poplar, since as a result of the hydroalcoholic
extraction of flavonoids are allocated, in particular pinotsembrin and pinostrobin and whose
presence and cause a high antimicrobial activity of extracts.
The greatest antimicrobial action has extracts of poplar buds black - when you make them
in IPA almost complete suppression of significant growth and development of colonies of
Staphylococcus aureus in comparison with single colonies under the influence of other
extracts.
Antimicrobial activity of extracts of other plants in relation to Staphylococcus aureus is
due to release from the original extraction of flavonoids and flavones, including extracts of
Glycyrrhiza glabra - naringenin, quercetin, kempfelola, Achillea micranta and Helichrysum
arenarium - naringenin, quercetin, azulene, etc. [7].
An examination of the chemical components of the extracts of various plants used in this
report by thin-layer chromatography, gas chromatography / mass spectrometry showed,
according to other studies and the literature, in an extract of the roots and rhizomes of
Glycyrrhiza glabra the presence of glucopyranoside, dioksiflavonon, naringenin,
parengenina, caffeine and other ingredients; inflorescences Helichrysum arenarium , Achillea
micranta the presence of quercetin, azulene, kaempferol, and others; and in extracts of
Populus nigra , according to published data, the presence of pinotsembrina and pinostrobina,
according to experimental data in the presence of asarone in aire marsh ( Acorus calamus )
[1,2,3,5,6,10,15].
