Abstract

Stylotella sp. sponge is a type of marine invertebrate animals that are widely distributed in Indonesian marine areas. One of the spreading areas of the Stylotella sp. sponge is in the Selayar Islands, South Sulawesi, Indonesia. Sponges have potential as a drug because they contain secondary metabolites. The aim study was to identify the types of secondary metabolite compounds and determine the bioactivity of Stylotella sp. compounds against MCF-7 breast cancer cells. The extraction method was used in the process of obtaining isolates because it is easy and economical. Testing the level of purity of isolates was carried out with three eluent systems which showed a single stain result. FTIR characterization results showed that pure isolates contained alkaloids which were characterized by the appearance of O-H, C-N, and C-H groups. The activity of MCF-7 cells using the colorimetric method showed an IC50 value of 14987.50 µg / mL, not toxic.

Abstract

Determination and characterization of the lycopene content of the n-hexane fraction from potato-leaved tomato (Solanum lycopersicum grandyfolium) using Fourier transform infrared (FTIR) spectrophotometry and UV-Vis spectrophotometry. This study aims to determine the levels and characterization of lycopene compounds from potato-leaved tomato fruit using FTIR and UV-Vis spectrophotometers. The methods in this research include maceration, liquid-liquid extraction, crystallization with antisolvent, chromatography with three eluent systems, identification of lycopene compounds, and characterization of lycopene compounds using FTIR and UV-Vis. The results showed the presence of lycopene compounds based on the spectrum with absorption peaks at wave numbers 2924, 18 cm-1 and 2863, 66 cm-1 indicating C-H (stretching); 1637, 43 cm-1 indicating C=C alkene; and the wave numbers of 1461, 63 cm-1 and 1422, 46 cm-1 indicating the presence of a CH2 (bending) functional group. The results of UV-Vis spectrophotometric characterization showed the presence of lycopene compounds at three main wavelengths, namely at 445, 467, and 500 nm. The level of lycopene compounds produced from the n-hexane extract of potato-leaved tomato fruit was 7.25 mg/gram

Abstract

Isolation of secondary metabolite compound has been conducted from sponge Stylotella sp., Selayar Island. Stylotella sp., one of Demospongiae class sponge, is found spreading in Selayar Island. This study aims to determine secondary metabolite compounds contained in the ethanol extract of Stylotella sp. sponge by extraction, fractionation and purification methods. The purity test was carried out by three eluent systems of TLC, namely chloroform:ethyl acetate (9:1), n-hexane:acetone (9:1), and chloroform:acetone (9:1). Each eluent produced a single spot. FTIR analysis of Stylotella sp. isolate showed that the pure isolates contained alkaloid compounds with the appearance of a typical functional group of alkaloid compounds. Keywords: Alkaloids, sponge Stylotella sp, extraction  Telah dilakukan isolasi senyawa metabolit sekunder dari spons Stylotella sp. asal Kepulauan Selayar. Spons Stylotella sp merupakan spons kelas Demospongiae yang ditemukan penyebarannya di Perairan Pulau Selayar. Penelitian ini bertujuan untuk mengetahui golongan senyawa metabolit sekunder yang terdapat pada ekstrak etanol spons Stylotella sp. dengan metode ekstraksi, fraksinasi dan pemurnian. Uji kemurnian dilakukan dengan uji tiga sistem eluen pada KLT yaitu kloroform:etil asetat (9:1), n-heksan:aseton (9:1), dan kloroform:aseton (9:1). Masing-masing eluen menghasilkan noda tunggal. Isolat hasil analisis FTIR menunjukkan bahwa isolat murni mengandung senyawa alkaloid dengan munculnya gugus fungsi khas senyawa golongan alkaloid. Kata kunci: Alkaloid, spons Stylotella sp., ekstraksi
