INTRODUCTION
Nettle (Urtica dioica L.) has a long history of wild-caught and human consumption. Although not
fully domesticated, the species remains popular even today for food and medicine, as reported,
for example, in Nepal and Poland [1,2].
Although the U. Dioica plant is recognized as an edible and highly nutritious plant, research
attention has focused more on its importance in non-traditional medicine. Clinical trials have
confirmed the efficacy of nettle root in the treatment of benign prostatic hyperplasia. Dried nettle
leaf preparations have also been shown to relieve symptoms associated with allergic rhinitis [3].
Urtica dioica has been reported to have various pharmacological properties such as: antibacterial,
antioxidant, analgesic, anti-inflammatory, antiviral, immunomodulatory, hepatoprotective, anti-
colytic and antitumor effects. The authors summarize information on ethnopharmacology,
phytochemistry, biological activity and toxicological summary of Urtica dioica [4,5].
Nettle herb contains flavonoids, phenolcarboxylic acids (caffeoyl malic, caffeic, chlorogenic),
tannins,
amines,
sterols,
carotenoids,
glucoquinones,
enzymes,
polysaccharides,
hydroxycoumarins, vitamins of group B, C, K macro - and microelements. In the leaves,
rhizomes and seeds of stinging nettle, 12 amino acids were identified, the total content of which
ranges from 0.23 to 13.5%. The leaves are dominated by aspartic acid, threonine, serine, alanine,
and in the roots - aspartic acid, threonine, serine [6].
Amino acids are one of the most natural universal regulators of metabolism and vital activity of
the human body. Compounds of this class are essential elements of normal human and animal
nutrition [7].
In tinctures of stinging nettle, 18 amino acids were identified. The content of the sum of free
amino acids in HMO (homeopathic matrix tinctures) is from 0.02 to 0.21% bound - from 0.03 to
0.29%, it was found that it is higher in HMO from fresh raw materials than in those from dried.
When comparing the content of amino acids before and after hydrolysis, it was found that amino
acids in HMO are predominantly in a free state. The discovered compounds can contribute to the
pharmacological action of medicinal plants and nettle preparations [8].
To determine amino acids in medicinal plant raw materials, a method was developed for the
separation and determination of the amount of free amino acids in aqueous extracts from
medicinal plant materials by TLC (using the example of sea buckthorn fruits and stinging nettle
leaves). The set of amino acids is individual for each type of plant material, and also depends on
the method of its conservation; this chromatographic profile for amino acids can be used to
standardize raw materials [9].
Pontic hawthorn (Genus Crataegus L) is represented by 15 species, but many of them differ in
very insignificant characters. The fruits of many species of hawthorn are used by the population
to one degree or another, but the most important is the Pontic hawthorn (Crataegus. Pontica C.
Koch.) Or "duliana" [10]. Hawthorn is a well-known food and medicine. Since ancient times, it
has been used as an effective medicine. Ancient medicine believed that when taken orally,
