Cytotoxic Activity of Selected Nigerian Medicinal Plants
Bibliographic record
Abstract
The study investigated eight Nigerian medicinal plants: Artocarpus communis fruit (Ac-F), Cassia sieberiana root bark (Cs-R), Eugenia uniflora leaf (Eu-L), Hibiscus rosa-sinensis flower (Hr-F), Laportea aestuans aerial part (La-A), Massularia acuminata stem bark (Ma-S), Trichilia heudelotii leaf (Th-L), and Xylopia aethiopica fruit (Xa-F), for anticancer activity. The alcoholic extracts of the plants were tested against human prostate DU-145, breast JIMT-1, and pancreatic BxPC-3 cancer cell lines using Methanethiosulfonate (MTS) assay, where chlorambucil was used as positive control. The active fractions were solvent-partitioned and tested against the three cancer cell lines. The results showed a concentration dependent decrease in cancer cell viability and cytotoxicity of four of the extracts, namely Massularia acuminata stem bark (Ma-S), Xylopia aethioipica fruit (Xa-F), Laportea aestuans aerial part (La-A), and Eugenia uniflora leaf (Eu-L). The petroleum ether fraction of X. aethiopica fruit (XP) demonstrated the greatest anticancer activity. At 75 µg mL−1, XP (37.2 ± 4.4%) was comparable to chlorambucil (39.88 ± 2.41%), in its cytotoxicity against breast cancer cell line JIMT-1.

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.
