Abstract
Introduction: Sargassum polycystum is one of marine algal which has a potent antioxidant anticancer activities. This research aims to investigate phytochemical composition, antioxidant activity, and in vitro cytotoxicity of marine algal Sargassum polycystum on cervical HeLa cancer. Methods: Sargassum polycystum collected from Dompu beach, Lombok, Nusa Tenggara Barat Province, Indonesia, were extracted into organic solvent of n-hexane, ethylacetate, chloroform and ethanol, respectively. Subsequently, Sargassum polycystum extracts were applied for Thin Layer Chromatography (TLC) analysis, phytochemistry test, total phenolic and total flavonoid contents, as well as for antioxidant activity test by DPPH (2,2-diphenyl-1-picrylhydrazyl) method, and in vitro cytotoxicity evaluation on HeLa cells by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5diphenyltetrazolium bromide) assay. Results: Phytochemical analysis of S. polycystum extracts are positive for metabolites of flavonoid, steroid, tannin and glycoside. TLC analysis revealed that S. polycystum extracts containing four phytochemical components. Ethylacetate extract of S. polycystum showed the highest total phenolic content, and exhibited greater antioxidant activity than ethanol extract. Total phenolic and total flavonoid content in ethylacetate extract are 548.61 g/mL and 40.06 g /mL, respectively. Ethylacetate extract of S. polycystum with IC 50 value of 298.3 g/mL is assigned to have a weak antioxidant activity against DPPH free radical. The results indicate that antioxidant activity of ethylacetate extracts of S. polycystum is directly correlated with its total phenolic and flavonoid content. Moreover, S. polycystum extracts demonstrated a strong anticancer activity on cervical HeLa cells with IC 50 ranging from 38.3 g/mL to 112.8 g/mL. Conclusion: This work confirmed that S.polycystum are promising natural antioxidant and anti-cervical cancer agents.

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
