Abstract

Macaranga merupakan salah satu genus terbesar dari famili Euphorbiaceae yang terdiri dari 300 spesies dengan nama lokal mahang-mahangan. Tumbuhan Macaranga tersebar luas di wilayah Afrika dan Madagaskar di bagian barat hingga ke wilayah tropis Asia, Australia utara dan kepulauan Pasifik. Di Indonesia tumbuhan Macaranga tersebar di beberapa daerah yaitu daerah Papua, Maluku, Sulawesi, Kalimantan, Sumatera, Bangka, dan Jawa. Kajian fitokimia beberapa spesies Macaranga menunjukan adanya kelompok senyawa fenolik yaitu turunan flavonoid dan stilben, serta turunan terpenoid. Senyawa turunan fenolik tersebut memiliki keunikan dari struktur molekulnya, yaitu adanya subtituen tambahan dari metabolit terpenoid yaitu prenil (C5), geranil (C10), farnesil (C15), dan geranilgeranil (C20). Pada penelitian ini telah dilakukan isolasi metabolit sekunder dari daun M. involucrata (Roxb.) Baill dengan metode maserasi menggunakan pelarut aseton, kemudian dilanjutkan pemisahan dan pemurnian dengan menggunakan kromatografi cair vakum dan kromatografi radial untuk mendapatkan senyawa murni. Penentuan struktur dilakukan berdasarkan analisis data spektrum NMR 1D (1H-NMR dan13C-NMR), NMR 2D (NOESY, TOCSY, HSQC, dan HMBC), dan spektrum massa (MS). Berdasarkan metodologi tersebut, dua senyawa turunan flavon yaitu 5,7,4’-trihidroksi-3’(3-metilbut-2-enil)-3-metoksiflavon (1) dan makarangin (2), telah berhasil diisolasi dari tumbuhan ini. Berdasarkan hasil penelitian tersebut menunjukan daun M. involucrata (Roxb.) Baill yang berasal dari Kabupaten Buton Tengah, Sulawesi Tenggara menghasilkan senyawa fenolik turunan flavonoid. Kata kunci: Euphorbiaceae, Macaranga involucrata (Roxb.) Baill, flavon. Macaranga is one of the largest genera of the family Euphorbiaceae comprising 300 species with local name “mahang-mahangan”. Macaranga is widespread in the region of Africa and the west of Madagascar to the tropical regions of Asia, northern Australia, and the Pacific islands. In Indonesia Macaranga spread in several areas:  Papua, Maluku, Sulawesi, Kalimantan, Sumatra, Bangka, and Java. Phytochemical studies showed the presence of several phenolic compounds such as flavonoids and stilbene derivatives. The phenolic compounds have a unique molecular structure with the addition of some substituents such as prenyl (C5), geranyl (C10), farnesyl (C15), and geranylgeranyl (C20). This research has been conducted on the isolation of secondary metabolites from the leaves of M. involucrata (Roxb.) Baill by maceration method using acetone, followed by separation and purification by using liquid vacuum chromatography and radial chromatography to obtain pure compounds. Determination of the structure is based on data analysis of 1D NMR spectrum (1H-NMR and 13C-NMR), 2D NMR (1H-1HCOSY, NOESY, TOCSY, HSQC, and HMBC), and mass spectra (MS). Based on this methodology, two flavone derivatives 5,7,4'-trihydroxy-3'(3-methylbut-2-enyl)-3-methoxy flavone (1) and macarangin (2), have been isolated from this plant. Based on these results showed that leaf of M. involucrata (Roxb.) Baill from Central Buton, Southeast Sulawesi produces phenolic compounds from flavonoid derivatives. Keywords: Euphorbiaceae, Macaranga involucrata (Roxb.) Baill, flavone.

Abstract

The problem of tilapia farming farmers is the presence of disease, which is caused by viruses, bacteria, fungi, and parasites. Prevention by farmers is the provision of vaccines, antibiotics, and immunostimulants. However, it is only effective in one type of disease. Therefore, alternative prevention is needed with natural ingredients from Macaranga tanarius leaf extract which has tannins, terpenoids, flavonoids, prenylflavonoids, and lignans that have immunostimulator properties. M. tanarius leaf extract was injected by intramuscular injection of tilapia. This research method used a completely randomized design (CRD) with five treatments with three repetitions. Treatment (P1) using physiological solution (positive control), P2 = 4 % (v/v) (1mL extract + 24 mL distilled water), P3 = 8 % (v/v) (2mL extract + 23 mL distilled water), P4 = 12% (v/v) (3mL extract + 22 mL distilled water) and P5 without injection of M. tanarius leaf extract (negative control). The results showed that the leaf extract of M. tanarius could respond to phagocytic activity (45.82%) and increase the number of white blood cells (12.43 x 108 cells/mL). Based on this study, the extract of M. tanarius showed an increase in the immune response of tilapia.

Abstract

This study investigates the utilization of different compositions of Fe2O3 and polyvinyl alcohol (PVA) to modify chitosan in order to prepare a composite membrane. The membranes were synthesized using the phase inversion method and extensively characterized by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), mechanical properties analysis, and water uptake analysis, whereby SEM was used to confirm the morphology of the composite membranes. Different electrochemical properties such as ion exchange capacity, proton conductivity, and methanol permeability of these membranes were also measured. The results showed that increasing the PVA mass improved the water uptake, ion exchange capacity (IEC), and proton conductivity because the PVA addition increased the hydrophilicity of the membrane; thus, the pore surface on the membrane was more open, which also caused higher membrane permeability. However, the methanol permeability values of all composite membranes were lower than that of Nafion. The highest IEC and proton conductivity were obtained for the CS-PVA-H3070 membrane, with values of 4.300 meq/g and 6.71 × 10−2 S·cm−1, respectively. The mechanical strength of these membranes showed that the PVA addition increased the elongation break and decreased the tensile strength of the membrane. The results imply that the chitosan membrane modified with PVA and Fe¬2O3 has a potential for DMFC applications.
