Brown seaweed (&lt;em&gt;Sargassum polycystum&lt;/em&gt;) can be used as a raw material in the industry and as a medicinal plant. Maintaining the quality of a compound requires an analytical method that can identify the diversity of metabolome profiles. &lt;strong&gt;Objective: &lt;/strong&gt;This investigation seeks to discover the metabolite profile of S. &lt;em&gt;polycystum&lt;/em&gt; from Sumenep, Madura Island, Indonesia, utilizing the UPLC-QToF MS/MS equipment. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; The extract was further fractioned using n-hexane, ethyl acetate, and water. The metabolite profiling of extract and fractions used the UPLC-QToF-MS/MS instrument. It was produced with SPE and then introduced into the MS Xevo G2-S QToF detector of the ACQUITY UPLC® H-Class System. The findings of the UPLC-QToF-MS/MS analysis were processed with the MassLynx 4.1 software to obtain chromatogram data and m/z spectra of each observed peak, which were then validated using the ChemSpider and MassBank databases. &lt;strong&gt;Results: &lt;/strong&gt;Based on the results of metabolite profiling using UPLC-QToF-MS/MS, the 96 % ethanol extract of S.&lt;em&gt; polycystum&lt;/em&gt; indicated a total of 61 compounds, the n-hexane fraction indicated a total of 55 compounds, the ethyl acetate fraction indicated a total of 67 compounds, and the water fraction indicated a total of 49 compounds. &lt;strong&gt;Conclusion:&lt;/strong&gt; There are 232 compounds in the extract and a fraction of S.&lt;em&gt; polycystum &lt;/em&gt;consisting of 168 known compounds and 64 unknown compounds.&lt;/p&gt;

This research aims to investigate phytochemical composition, antioxidant activity and &lt;em&gt;in vitro &lt;/em&gt;cytotoxicity of marine algal &lt;em&gt;Sargassum polycystum &lt;/em&gt;on cervical HeLa cancer.&lt;strong&gt; Methods:&lt;/strong&gt; &lt;em&gt;Sargassum polycystum&lt;/em&gt; collected from Dompu beach, Lombok, Nusa Tenggara Barat Province, Indonesia, were extracted into organic solvent of n-hexane, ethylacetate, chloroform and ethanol, respectively. Subsequently, &lt;em&gt;Sargassum polycystum&lt;/em&gt; 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]-2,5- diphenyltetrazolium bromide) assay. &lt;strong&gt;Results: &lt;/strong&gt;Phytochemical analysis of&lt;em&gt; S. polycystum&lt;/em&gt; extracts are positive for metabolites of flavonoid, steroid, tannin and glycoside. TLC analysis revealed that &lt;em&gt;S. polycystum&lt;/em&gt; extracts containing four phytochemical components. Ethylacetate extract of&lt;em&gt; S. polycystum&lt;/em&gt; 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 μg/mL and 40.06 μg /mL, respectively. Ethylacetate extract of &lt;em&gt;S. polycystum&lt;/em&gt; with IC&lt;sub&gt;50&lt;/sub&gt; value of 298.3 μg/mL is assigned to have a weak antioxidant activity against DPPH free radical. The results indicate that antioxidant activity of ethylacetate extracts of &lt;em&gt;S. polycystum&lt;/em&gt; is directly correlated with its total phenolic and flavonoid content. Moreover, &lt;em&gt;S. polycystum&lt;/em&gt; extracts demonstrated a strong anticancer activity on cervical HeLa cells with IC&lt;sub&gt;50 &lt;/sub&gt;ranging from 38.3 μg/mL to 112.8 μg/mL. &lt;strong&gt;Conclusion:&lt;/strong&gt; This work confirmed that S.polycystum are promising natural antioxidant and anti-cervical cancer agents.&lt;/p&gt;
