Abstract
The results of solid-phase analysis of complexes of flavonoids with Ca(II) and Al(III), which were obtained from the aqueous extract of the inflorescences of the canadian goldenrod, are presented. The methods of reflectance spectroscopy in the visible range and colorimetry (CIE XYZ, CIE L*a*b* systems) were used to characterize the preparations. A bathochromic shift of the long-wave band in the reflectance spectra of the complexes relative to unassociated flavonoids was revealed, which is associated with an increase in the degree of conjugation in the chromophore system as a result of binding with metal ions. The criteria of differential spectrophotometry and colorimetry are proposed to confirm the differences between the complexes of flavonoids with Ca(II) and Al(III). The obtained results confirm the prospect of expanding the raw material base for obtaining biologically active metal complexes of flavonoids, improve the methodological basis of non-destructive analysis of dyes such as aluminum lakes, and can also be used in the development of biohybrid materials.

Full frame distilled prediction
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
