Phytochemical screening and evaluation of cytotoxic activity of Pandanus fascicularis L. (Fruits)
Bibliographic record
Abstract
The present study was conducted to evaluate possible phytochemicals present, and cytoctoxic activity of extract of fruits of Pandanus fascicularis L. Phytochemical screening was carried out using the standard test methods of different chemical group. Evaluation of cytotoxic activity was done using the brine shrimp lethality bioassay. The aqueous, methanolic, ethanolic, ethyl acetate, pet ether and chloroform extracts show presence of maximum phytochemicals such as alkaloids, tannins, flavonoids, steroids, saponins, proteins, terpens, phenols, glycosides, carbohydrate in different fractions etc. During cytotoxicity test, the positive control groups showed nonlinear mortality rates at lower concentrations and linear rates at higher concentrations. The LC50 values of Chloroform extract was found 1.0636 µg/ml where the positive control vincristine sulphate showed LC50 at a concentration of 0.200µg/ml. Therefore, the plant extract possess potent cytotoxic effect.

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.
