Abstract
Psoralea corylifolia is a well-known medicinal plant, traditionally used against several diseased conditions. The present study was conducted to investigate the phytochemical composition and antimicrobial activity of P. corylifolia seeds. Non/less-polar fraction of methanolic seed extract was subjected to gas chromatography-mass spectrometry (GC-MS) for phytochemical analysis. A total of fourteen compounds were identified which include aromatic, sesquiterpenes, furocoumarins, sterols, fatty acid and their methyl esters. The predominant compounds were epoxycaryophyllene (3), isopsoralen (6), psoralen (7) and bakuchiol (9). Identification of these compounds was also strongly supported by Kovat’s Retention Indices. Furthermore, the n-hexane soluble fraction showed significant antimicrobial activity against several bacterial strains. P. corylifolia seeds represented a unique chemical composition with considerable antimicrobial activity which not only validates their traditional medicinal uses but also indicates their potential as a source of natural antimicrobial compounds.

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
