Overall, FTIR data show tetrahedral and octahedral functional groups that create clay minerals. There is a decrease in absorption intensity due to acid's influence, which dissolves cations in the octahedral and interlayer clay. The XRD analysis shows the Hatu natural clay contains montmorillonite, alumina, kaolinite, quartz, and illite minerals.

SEM images of natural clay before and after activation-calcination shows the morphology of porous and layered material, while the mapping of the surface of natural clay shows irregular and rough material topography. The EDX spectra showed four elements with the most extensive composition: O, Si, Al, and Fe. XRF data confirmed three components that have the highest mass percent, namely SiO2, Al2O3, and Fe2O3. Dealumination occurs at 0.95% due to activation by sulfuric acid along with calcination. TEM images clearly show the multilayered silicate materials. The higher nitrogen gas uptake by activated-calcinated natural clay is proportional to the large surface area and total pore volume.","PeriodicalId":18773,"journal":{"name":"Molekul","volume":"99 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139257658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endophytic fungi excrete specialized bioactive compounds beneficial for of its host; the compound itself can be different from what can be found on their host. Endophytic fungi are capable to excrete biologically significant secondary metabolites acting as antidiabetic, antioxidant, antimicrobial, and cytostatic agents. Endophytic fungi existence are common across different plants; including Syzygium zeylanicum that can be found in Indonesia. This study aims to isolate endophytic fungi found in leaves of Syzygium zeylanicum, L., to elucidate their characterized morphologically, and to examine its antimicrobial and antioxidant properties in addition to their chemical structures. Characterization of endophytic fungi was conducted by their macroscopic and microscopic features, followed by molecular characterization of highly bioactive metabolites. Antimicrobial activities were measured by disc diffusion method. Antioxidant properties were measured with DPPH. Secondary metabolites were chromatographically isolated and identified with spectroscopy techniques (NMR ID and 2D). Four endophytic fungi isolates were obtained: Penicillium citrinum (SZ1), Colletotrichum lindemuthianum (SZ2), Aspergillus nidulan (SZ3), Scopulariopsis asperula (SZ4). Penicillium citrinum (SZ1) showed antimicrobial activities against four different bacteria (71.3% against E. coli; 74.1% against S. aureus; 76.2% against S. typhi; and dan76.9% against B. subtilis). Antioxidant activity ini all ekstrak of endophytic fungi showed very activity (IC50 SZ3 extract = 3.85 µg/mL). Potential endophytic fungi SZ1 was molecularly identified as Penicillium citrinum.

Through a process called Steglish esterification, the initial cholesterol and ergosterol are converted into their respective aldehyde derivatives, by reacting with amines such as 2-amino 6-fluoro benzothiazole, carbohydrazide, and thiosemicarbazide, these aldehyde derivatives are transformed into the appropriate Schiff base derivatives, and then their anticancer activity is checked using the MTT (Microculture Tetrazolium Assay) assay method.
