Abstract
Health beneficial properties of Rosa canina species are mainly attributed to rose hips, while the leaves are usually discarded as waste. In the present study we investigated chemical constituents as well as antimicrobial and antibiofilm potential of R. canina methanolic leaf extract. Chemical analysis showed that dominant phenolic compounds are quercetin and isorhamnetin derivatives (isoquercetin and isorhamnetin-3-O-rutinoside). Among the tested bacteria, Pseudomonas aeruginosa and Salmonella typhimurium were the most susceptible to the activity of R. canina leaf extract with MIC and MBC values both 0.009 mg mL(-1). For most of the bacterial strains investigated the extract showed significantly higher activity compared to the used standard compounds streptomycin and ampicillin. Also the tested extract powerfully inhibited in vitro biofilm growth in Pseudomonas aeruginosa, Staphylococcus aureus, Leishmania monocytogenes and Escherichia coli at sub MIC-levels. With concentrations equal to 1/4 and 1/8 of MIC values biofilm growth of P. aeruginosa and E. coli was inhibited by 90%. The obtained results are significant for a wider and efficient use of R. canina leaves.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
