Screening of Biological Activities of Ethanol Extracts from Several Varieties of Endives
Bibliographic record
Abstract
We investigated the biological activities of ethanol extracts obtained from five endive cultivars. Free radical-scavenging activities of extracts from Redoria, Halifax, Vintor, Kibora, and Metafora cultivars were 94.2%, 60.8%, 66.6%, 70.0% and 67.4%, respectively. The extract from Redoria showed the highest activity among all the tested samples including BHT (Butylated hydroxyanisole) and vitamine C, known as antioxidant. Endive extracts slightly (17.5 - 38.6%) inhibited -glucosidase activity. However, there is no inhibitory activity against -amylase. In terms of proteolytic activity, all endive extracts showed strong activity than pancreatin (used as a positive control), and the extract of Redoria also exhibited stronger activity than other extracts as well as free radical scavenging activity. These results indicate that endive, especially the Redoria cultivar, can be used as a natural resource for development of antioxidants or materials aiding digestion.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
