Abstract

Characterization of secondary metabolites and cytotoxic testing of Haliclona sp. against T47D breast cancer cells were conducted in this study. The objective was to assess the cytotoxicity of T47D cancer cells and identify the functional groups involved. The research methods employed included maceration, partitioning, phytochemical testing, toxicity testing using the BSLT method, separation through flash column chromatography (FCC), cytotoxic testing using the MTT method, and characterization using FTIR. The partition results of methanol extract consist of n-hexane, ethyl acetate, and methanol-water fractions. The methanol extract demonstrated high toxicity, with an LC50 of 5.21 ppm. Among the fractions, the ethyl acetate fraction exhibited the highest toxicity compared to the n-hexane and methanol-water fractions, with LC50 values of 25.76 ppm, 42.71 ppm, and 55.26 ppm, respectively. Phytochemical testing of the ethyl acetate fraction yielded positive results for terpenoids, steroids, alkaloids, and phenolic compounds. The ethyl acetate fraction was further separated using flash column chromatography, resulting in ten combined fractions (M1-M10). The cytotoxicity tests of the M3 fraction against 747D breast cancer cells showed non-toxic effects, with an IC50 value of 1382.29 ppm. The FTIR analysis of the M3 fraction revealed the presence of functional groups such as O-H, =C-H, C-H aliphatic, C=O, and C=C, which is indicative of the presence of terpenoids, steroids, and esters.

Abstract

Synthesis of composite boron-doped carbon nanodots (B-CDs)/TiO2 using the sol-gel method performed with titanium tetraisopropoxide (TTIP) precursor and B-CDs prepared by the microwave method using citric acid monohydrate, urea, and boric acid as precursors. The optimum concentration of boron dopant (B) on B-CDs/TiO2 is 0.5% boron (w/w) which is then used as a composite on TiO2 resulting in a brown solid and has blue luminescent under UV light. The result with UV-Vis/DRS for variation in B-CDs concentration of 0.5%, 1.25%, and 2.5% showed Eg values of 2.34 eV, 2.00 eV, and 2.29 eV. B-CDs cause the maximum emission peak (λEm) to redshift and affect the intensity of photoluminescence TiO2. The characterization of FT-IR does not indicate a new peak, there is no bonding in the B-CDs/TiO2 composite. The TiO2 diffractogram was observed to shift towards a larger 2θ which caused the crystallinity of TiO2 to decrease. Based on the photocatalytic activity test on the degradation of methylene blue solution, it showed fairly good activity. It is expected that the B-CDs/TiO2 composite has the potential to be applied as a photocatalyst to degrade organic pollutants under visible light illumination.

Abstract

Characterization of nonpolar organic compounds of macroalga Padina minor from Singkawang waters and activity against Staphylococcus aureus and Escherichia coli bacteria has been carried out. The stages of this research consisted of maceration, fractionation, phytochemical tests, characterization using FTIR and GC-MS, as well as testing the antibacterial activity with the well-diffusion method. The fractionation process produces n-hexane, dichloromethane, and methanol fractions. The n-hexane fraction was selected for packaging using gradient n-hexane: dichloromethane eluent and yielded 11 combined fractions (F1RW1-F1RW11). The combined fraction F1RW2 was separated again using n-hexane: dichloromethane eluent in a gradient manner and 18 combined fractions (F2RW1-F2RW18) were obtained. Then the F2RW4 isolate was characterized for GC-MS characterization and the F2RW3 isolate was characterized using FTIR. The FTIR interpretation results show the absorption of hydroxyl groups O-H (345.65 cm-1), C=O (1743.65 cm-1), C=C bonds (1633.71 cm-1), C-H (2926.01; 2854.01, 1438.9 and 723.31 cm-1), and C-O-C bonds (1170.79 cm-1). The results of the GC-MS analysis showed that the F2RW4 fraction had 2 main compounds, namely methyl decanoate and 11-methyl octadecenoate. The results of the antibacterial activity test showed that the methanol extract and n-hexane fraction of Padina minor were inactive against the inhibiting bacteria Staphylococcus aureus and Escherichia coli. Keywords:  Padina minor, FTIR, GC-MS, Antibacterial

Abstract

The Cu(II)-doped TiO2 and Cu(II)-doped TiO2 /Bi2O3 compound have been synthesized using the sol gel method with titanium tetraisopropoxide (TTIP) as the TiO2 precursor and Cu(NO3)2.3H2O as the Cu(II) dopant was carried out at various concentration of 0.075%; 0.250% and 1.000%, as well as Bi(NO3)3.5H2O as a Bi2O3 precursor. Based on characterization using the DRSUV-Vis spectrophotometric method with data analysis using a tauch plot, it is known that the band gap energy of Cu(II)-doped TiO2 is 2.89 eV; 2.72 eV; 2.54 eV. The addition of Bi2O3 to Cu(II)-doped TiO2 (1%) causes a decrease in the band gap from 2.54 to 2.18 eV which is equivalent to a wavelength of 567 nm. IR spectrophotometry spectra analysis shows a shift in Ti-O absorption towards smaller wave numbers. Characterization by the XRD method shows that 1% Cu(II)-doped TiO2 /Bi2O3 has an anatase phase with a crystallite size of 24 nm. Photocatalysis activity test on the degradation of rhodamine B solution at a concentration of 10 ppm, under visible light illumination for 180 minutes was able to degrade up to 85.85%.

Abstract

AbstractThe use of heavy-metal mordants in fabric dyeing is prohibited due to the resulting impacts such as environmental damage and public health, therefore environmentally friendly and non-toxic mordants such as tannin mordants (biomordants) are needed. Based on phytochemical screening on fern species (Pteridophyta), it is known that they contain tannins. However, scientific evidence of determining the total tannin content of various species of ferns has so far not been found. This study aims to determine the yield and total tannin content of methanol extracts of five fern species, namely paku kawat (Lycopodium cernuum), paku resam (Gleichenia linearis), paku dayak (Blechnum orientale), paku uban (Nephrolepis biserrata), paku miding (Stenochlaena palustris). Sample extraction was carried out by maceration method using methanol solvent. Extract yield was determined by weighing method. Analysis of total tannin content was carried out by UV-Vis spectrophotometric method at a wavelength of 755.8 nm using Folin-Ciocalteu reagent and sodium carbonate. The results of the research obtained the yield of methanol extracts on paku kawat, paku resam, paku dayak, paku uban, and paku miding are 11.271%; 8.389%; 4.810%; 3.615%; and 0.854%, respectively. Total tannin levels in methanol extracts of paku kawat, paku resam, paku dayak, paku uban, and paku miding were 0.024% ± 0.002; 0.256% ± 0.029; 0.272% ± 0.037; 0.143% ± 0.019; and 0.022% ± 0.012, respectively. Based on these data, it can be concluded that the methanol extract of paku kawat produces the highest yield while paku dayak produce the highest total tannin content. The results indicate that differences in fern species cause differences in tannin levels.

Abstract

Synthesis of sulphur-doped carbon nanodots immobilized on the TiO2 surface (SCDs/TiO2) composite was carried out using the sol-gel method with SCDs and titanium tetraisopropoxide (TTIP) as precursors. SCDs were prepared from citric acid monohydrate, urea, and sodium disulphite using the microwave technique. SCDs/TiO2 was then visually observed under UV 365 nm and characterized by UV-Vis diffuse reflectance spectrophotometry (UV-Vis/DRS), Photoluminescence (PL) spectroscopy, Fourier transform infrared (FT-IR), and X-ray diffraction (XRD). The SCDs/TiO2 composite product had a brown solid with a green luminescent under UV light. Furthermore, UV-Vis/DRS for variations in SCDs concentrations of 0.5%; 1.25%, and 2.5% showed Eg values of 2.33 eV, 2.14 eV, and 1.61 eV, respectively. The results showed that SCDs caused the maximum emission peak (λEm) to redshift and also affected the intensity of PL TiO2. There was also a shift in the absorption peak towards the visible light region. Based on the results, the 0.5% SCDs/TiO2 was the optimum concentration with the lowest intensity as an indication of separation of the (e-) and (h+) charge pairs, which greatly enhanced the photocatalytic efficiency.

Abstract

Spons Haliclona sp. termasuk ke dalam kelas Demospongiae yang memiliki kandungan metabolit sekunder berupa alkaloid, terpenoid, fenolik, dan steroid. Metabolit sekunder tersebut dapat berperan sebagai antibakteri, antikanker, antiinflamasi, dan antivirus. Tujuan penelitian ini adalah mengarakterisasi metabolit sekunder dan menguji aktivitas antibakteri fraksi etil asetat terhadap Staohylococcus aureus menggunakan metode difusi sumuran. Hasil interpretasi FTIR pada isolat menunjukkan adanya serapan gugus O-H melebar (3448,72 cm-1), =C-H (3016,67 cm-1), C-H alifatik (2927,94 cm-1), C-O alkohol (1118,71 cm-1); C=C olefin (1631,78 cm-1) C-X halogen (617,22- 410,84). Kehadiran gugus-gugus fungsi tersebut dan hasil uji fitokimia dapat diduga bahwa isolat merupakan senyawa olefin dari kelompok terpenoid. Hasil uji aktivitas antibakteri menunjukkan bahwa fraksi etil asetat menghambat bakteri Staphylococcus aureus pada konsentrasi 50 µg/µL dan 25 µg/µL masing-masing menunjukkan kapasitas kuat dalam menghambat bakteri, sedangkan pada konsentrasi 12,5 µg/µL terindikasi lemah; dan 6,25 µg/µL tidak menunjukkan aktivitas dalam menghambat bakteri S. aureus.  Hasil uji fitokimia fraksi etil asetat memberikan respon positif untuk senyawa terpenoid dan alkaloid.
