Abstract
The regular consumption of polyphenol-rich foods is essential to prevent the onset of diseases. Wild fruits are known to possess higher levels of bioactive components than the domesticated fruits because of the severe environmental conditions they are grown in. The aim of this study was to evaluate the phytochemical profiles, and antioxidant and antiproliferative activities of a wild pink bayberry fruit after in vitro digestion and to compare them with results obtained with a chemical extraction method. A low release of total phenolics and anthocyanins was observed after digestion compared with chemical extraction, while more flavonol contents were found by HPLC analysis. The digesta samples demonstrated low levels of extracellular antioxidant activity (EAA) and cellular antioxidant activity (CAA). However, the cellular uptake rate was increased during the in vitro digestion, and the largest value of 75.35% was obtained in the colon step. Notably, the antiproliferative activity in the colon digesta (10.14 ± 0.13 mg mL-1) was close to that of extracts (7.6 ± 0.63 mg mL-1). Pearson correlation analysis revealed that EAA and CAA were significantly correlated with TPC, while the antiproliferative activity was significantly correlated with the total contents of three flavonol compounds (quercetin, kaempferol, and myricetin). Our observations provide new insights into the bioactivity variation of whole fruits as affected by simulated digestion.

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
