Extracts of the Canadian goldenrod (Solidago Canadensis L.) – promising agents with antimicrobial, anti-inflammatory and hepatoprotective activity
Bibliographic record
Abstract
S. canadensis L. and S. virgaurea L. are the most common species of Solidago L. in Europe and with a long tradition of use in medicine for various therapeutic purposes: diseases of the urinary tract, gastrointestinal tract, diabetes, allergies and antiseptic purposes. Therefore, the research of species of the Solidago genus, which have a rich content of natural BACs, and the development of new effective medicinal products of plant origin are relevant. The aim. The method of work is the phytochemical and pharmacological study of extracts of the Canadian goldenrod herb, obtained by ethanol solutions of various concentrations, for the innovative perspective of creating new medicines based on them with antimicrobial, anti-inflammatory and hepatoprotective activity. Materials and methods. The objects of the study were extracts of herb from Canadian goldenrod, obtained using purified water, 40 %, 70 % and 90 % ethanol. Phytochemical study of the extracts was performed by TLC and spectrophotometry. Study of acute toxicity, antimicrobial, anti-inflammatory and hepatoprotective activity of extracts was carried out according to standard methods. Research results. A study of the phytochemical composition and pharmacological activity of extracts of herb from Canadian goldenrod obtained with different solvents. It was established that extracts of herb from Canadian goldenrod show anti-inflammatory activity. The most pronounced antiexudative activity is shown by the extract of the Canadian goldenrod herb (extractant - 40 % ethanol), reducing the degree of swelling by 24.77 %. Herb extracts from from Canadian goldenrod in acute toxic liver damage show moderate hepatoprotective activity, which is somewhat inferior to the comparative drug "Silibor". A more intense and effective effect on the hepatobiliary system was shown by the extract of the Canadian goldenrod herb (extractant - 40 % ethanol). Conclusions. The perspective of creation based on herb of Canadian goldenrod new drugs with hepatoprotective activity. The most promising substance turned out to be an extract of herb from Canadian goldenrod obtained with a 40 % ethanol solution.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
