Abstract

fetched live from OpenAlex

Nowadays flowers and fruits of various types of hawthorn are widely used as cardiotonic drugs in Russian Federation. In our opinion a promising species for harvesting raw materials is Quebec hawthorn (Crataegus submollis Sarg., Rosaceae). Quebec hawthorn is successfully cultivated on the territory of the Russian Federation and is characterized by rapid growth and high yield in comparison with wild species. An additional point is that one of the possible types of raw materials are hawthorn leaves widely used abroad. Quebec hawthorn leaves contain flavonoids, among which there is a hyperoside. The maximum of the absorption curve of the extract solution of Quebec hawthorn leaves with an aluminum chloride solution of 412 nm. We have developed a quantification method for determination the total flavonoids in the Quebec hawthorn leaves calculated as hyperoside. It was established that the optimum extraction solvent for this raw material is 70% ethanol. The level of content and dynamics of accumulation of the total flavonoids in the Quebec hawthorn leaves during the growing season of 2017 was studied. The maximum content of total flavonoids in the Quebec hawthorn leaves (3.12 ± 0.05% calculated on hyperoside) is observed in May, during plant flowering. The liquid extract based on Quebec hawthorn leaves possesses moderate antidepressant activity. For this reason, leaves of Quebec hawthorn leaves are promising medicinal plant raw materials.

Teacher imitation

Not 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.
