The flora of Kazakhstan is rich in promising little-studied plants that are used in
traditional medicine, but additional research is required
for their introduction into
medicine. The objects of the study are the aerial part of the plant of the genus
Myricaria
(Myricaria bracteata Royle)
, collected in the Almaty region Enbekshikazakh district,
the Zaili Altau ridge,
the gorge of the Turgen River, in the vicinity of the village of
Batan.
In this work, methods of investigating the quality of raw materials of the
M.bracteata
plant have been worked out: humidity - 4.75%, total ash - 5.78%, sulfate ash - 10.85%,
extractive substances - 25.54% (70% water-ethyl alcohol).
The content of macro- and
microelements was determined by atomic absorption spectroscopy. The highest content
of iron is - 3.38% and potassium is - 0.35%.
The qualitative and quantitative composition of the plant was studied, carbohydrates,
organic acids, coumarins, tannins, flavonoids and terpenoids were found. The highest
content of tannins is 7.84%, carbohydrates - 6.77% and flavonoids - 4.12%.
Technological parameters for obtaining the substance from the
M.bracteata
plant have
been worked out: the extractant - 70%
water-ethyl alcohol, the ratio of the extractant
and raw materials - 1:9, the extraction time - 24 hours, the temperature - 24-25℃. Fatty
acid components were determined qualitatively and quantitatively by gas-liquid
chromatography (GLC). During which 8
fatty acids were identified, among which
unsaturated fatty acids predominate - linoleic - 47.8% and oleic acids - 33.4%, and
among saturated ones - palmitic acid - 10.6%. Vitamins A,
E were determined by the
fluorimetric method of analysis, which showed that in the studied plant species the
highest content of vitamin E (tocopherol) is 3.5 mg/100 g.
In the aqueous extract, 20
amino acids were identified by GLC methods, and vitamin C was determined by the
titrimetric method in an amount of 10.1 mg/100 g. CO
2
extract
was obtained by
supercritical fluid extraction. The GC/MS method was used to study the component
composition of the CO
2
extract, which identified 51 components in the carbon dioxide
extract. The analysis of antioxidant components showed that the content of fat-soluble
antioxidant was 1.67±0.03 mg/100g, and the content of water-soluble antioxidant was
2.93±0.04 mg/100g.
