Celandine -
Chelidonium majus L
. - belongs to the
Papaveraceae
family. Celandine
grows
on cool lands, among shrubs, on forest edges, in ravines,
in places, in settlements,
in gardens and fields. The celandine plant is found in Europe, Altai,
Central Asia,
Siberia and the Far East. It grows in small groups, but in some cases, it can also form
thickets. Celandine loves moist and fertile soils.
The celandine plant exhibits such pharmacological effects as antimicrobial, antiviral,
anti-inflammatory, antispasmodic. Dry extracts obtained from medicinal plants are used
for new drugs. Based on this, a dry extract was obtained from grass celandine.
The resulting extract was evaluated according to the following parameters:
appearance, exposure, weight loss on drying, moisture content, amount of heavy metals,
microbiological purity and quantitative determination of the amount of alkaloids. These
studies were identified using the methods presented in the following regulatory
documents: "UzR SF I, RF SF XIV, IPA.1.4.1.21 "Extracts", European Pharmacopoeia,
9
th
edition "Extracts"".
Based on the results obtained, the extract is a brown powder with a specific odor. Its
authenticity was determined by carrying out quality tests
on the main influencing
substance, i.e. alkaloids. Under the influence of 10% sulfate and silicon tungstic acid, a
white-yellowish precipitate precipitated.
According to the requirements of regulatory documents, during drying, the mass loss
should not exceed 5%. In the analyzed dry extract, this index was 3.92%.
The color of the prepared solution for determining the amount of heavy metals, the
color of the solution is not darker than the color of the standard solution, that is, the dry
extract, which is also analyzed for this indicator, corresponds
the requirements of
Normative Documents.
No bacteria were found in 1 g of dry extract of
Pseudomonas aeruginosa
,
Staphylococcus aureus, Escherichia coli
. It was found that the total number of aerobic
microorganisms is no more than 10
4
КОЕ, yeast and mold fungi - from 10
2
КОЕ, bile-
resistant enterobacteria - no more than 10
2
КОЕ.
To determine the amount of accumulation of alkaloids in
relation to the chelidonin
contained in the dry extract of celandine, the method presented in the pharmacopoeia
was used: this index was 1.3%.
According to the results of the studies, the dry extract of the celandine according to
the indicators corresponds to the qualitative and quantitative requirements of the current
normative documents. In the future, the dry extract is planned to be used as the basis for
obtaining a wound healing and anti-inflammatory ointment.
