Antibacterial and Antifungal Activity Essay of Alkaloids Extracted from Four Combretaceae Used in Senegal
Bibliographic record
Abstract
The use of medicinal plants remains important in West Africa where Combretaceae are among the most widely used for the treatment and herbal teas. The objective of this study is to extract total alkaloids from four plants of the Combretaceae family and test their antibacterial and antifungal activities. The results of the extraction showed that Combretum glutinosum is the richest with 0.61% in alkaloids. It is followed by Anogeissus leiocarpus, 0.13%. The study of antimicrobial activity has globally shown that alkaloids are more active against fungi than against bacteria. In this study, the lowest MIC, 93µg/ml, was obtained with alkaloids from Guiera senegalensis against Staphylococcus aureus. On the other hand, the total alkaloids extracted from Combretum glutinosum are the only ones that are active against all strains, both bacterial and fungal.

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.
