From the data given in table 1. It can be seen that some amino acids are absent, for example:
valine was not detected in an alcoholic solution of nettle, but its content in the aqueous extract
was 0.12212 mg / ml. In the alcoholic extract of Crataegus L, the valine content is relatively high
and amounts to 0.955871 mg / ml, and in the aqueous extract of the Urtica dioica L plant, the
valine content is one hundred times less and is 0.00908 mg / ml.
The absence of methionine is observed in the extracts of the aerial part of the plant Urtica dioica
L and in the extract of the plant Crataegus L. The content of the alcoholic extract is 0.24054 mg /
ml.
According to the literature, in nettle leaves, the total amino acid content ranges from 0.23 to
13.5%, and in our case, its content in the leaves is 0.196%. But in an aqueous solution of Urtica
dioica L, 17 free amino acids were found with a total content of 0.086%. Amino acids are well
extracted in alcohol solutions. In the leaves of nettle in an alcohol solution, the content of
aspartic acid is 0.016%
The absence of histidine was observed in the composition of the plant Urtica dioica L and in the
plants of Crataegus L. The alcoholic extract was 0.019%, and in the aqueous extract it was
0.013%.
Tryptophan was not detected in the aqueous extract of the nettle plant, but in the alcoholic
extract of 0.02898 mg / ml. In the alcoholic extract of hawthorn plants, the tryptophan content is
0.11960 mg / ml, and in the aqueous extract 0.08727 mg / ml,
The amino acid glycine was found in all samples, and the highest content in the aqueous extract
of hawthorn was 0.37282 mg / ml. In nettle with an alcoholic extract 0.08116 mg / ml, in an
aqueous extract 0.01563 mg / ml. In hawthorn with alcohol extract 0.102215 mg / ml.
As can be seen from the data in Table 1, glutamine, serine, glycine, aspartic acid, threonine,
alanine, arginine, cysteine, proline, and valine predominate in the leaves in the alcoholic extracts
of the Crataegus L plant. The total content is 0.72%.
