Abstract
Wild berries are a rich source of various biologically active substances. This paper focuses on the investigation of most common Russian forest berries on the total content and profile of anthocyanins, proanthocyanidins and total antiradical and antioxidant activity in 1-diphenyl-2-picrylhydrazyI (DPPH) and ferric reducing antioxidant power (FRAP) tests. Among berries analyzed were representatives of Ericacea family – bilberry, blueberry, crowberry, lingonberry, cranberry (V. oxycoccus and V. macrocarpon), of Caprifoliaceae family – honeysuckle, elderberry, vilburnum and Rosaceae family – chokeberry and saskatoon berry. Total anthocyanins were determined by pH-differential spectrophotometry, anthocyanin profile – by HPLC-TOF-mass-spectrometry, sum of proanthocyanidins – was estimated by colorimetry after butanol-hydrochloric acid hydrolysis. More than 100 samples of berries were selected from the northwestern and northern regions of the European part of Russia and western Siberia. The obtained data on the specific composition of anthocyanins and antioxidant properties of domestic berries are relevant to assess their potential effectiveness as a raw material for biological active food supplements and fortified foods and to develop criteria for authenticity and nutritional value of the berry raw materials.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
