Abstract
ABSTRACT The antioxidant activity of enzymatic extracts from Perilla frutescens var. crispa was evaluated using 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical, hydroxyl radical and alkyl radical‐scavenging activity by employing an electron spin resonance methodology. P. frutescens var. crispa was enzymatically hydrolyzed by eight carbohydrases (Dextrozyme, AMG, Promozyme, Maltogenase, Termamyl, Viscozyme, Celluclast, BAN [Novo Co., Novozyme Nordisk, Bagsvaerd, Denmark]) and nine proteases (Flavourzyme, Neutrase, Protamex, Alcalase, PP‐trypsin [trypsin from porcine pancreas; Novo Co.], papain, pepsin, α‐chymotrypsin, BP‐trypsin [trypsin from bovine pancreas; Sigma Chemical Co., St. Louis, MO]). The DPPH radical‐scavenging activities of Dextrozyme and Neutrase extracts from P. frutescens var. crispa were the highest and the IC 50 values were 60.12 and 112.81 µg/mL, respectively. All enzymatic extracts of P. frutescens var. crispa scavenged hydroxyl radical and the scavenging activity increased in a dose‐dependent manner; the IC 50 values of Viscozyme and BP‐trypsin, which showed the highest activity, were 0.78 and 0.26 mg/mL, respectively. In addition, the Termamyl and Protamex extracts of P. frutescens var. crispa showed the highest alkyl radical‐scavenging activities, and the IC 50 values were 248.13 and 415.23 µg/mL, respectively. The Viscozyme and BP‐trypsin extracts from P. frutescens var. crispa showed protective effect against H 2 O 2 ‐induced DNA damage. These results indicate that enzymatic extracts of P. frutescens var. crispa possess antioxidant activity. PRACTICAL APPLICATIONS Perilla frutescens var. crispa could be used to produce protein and carbohydrate extracts with antioxidative activeity. Many industrial commercial enzymes, such as Promozyme, Celluclast 1.5 L FG, Maltogenase L, Viscozyme L, Termamyl SC, Dextrozyme E, AMG 300 L, Protamex, Flavourzyme 500 MG, Neutrase 0.8 L, Puncreatic Trypsin and Alcalase 2.4 L, could also be used to attain the extracts processing the high antioxidative activity. The extracts can be used as natural antioxidants.

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
