Abstract

ABSTRAKMalaria merupakan salah satu penyakit infeksi yang memberikan morbiditas yang cukup tinggi di dunia dan merupakan infeksi yang ketiga teratas dalam jumlah kematian. Di Indonesia, pemberantasan penyakit malaria kurang maksimal karena adanya resistensi parasit terhadap obat antimalaria dan gangguan sistem imun. Monosit merupakan sel efektor imun yang penting dalam perlindungan terhadap patogenesis malaria yang bersifat sitostatik dan sitotoksik. Tanaman pandan wangi (Pandanus amaryllifolius Roxb.) memiliki senyawa yang dapat bekerja sebagai antimalaria dan imunomodulator. Tujuan penelitian ini yaitu mengetahui efektivitas ekstrak metanol akar pandan wangi sebagai antimalaria terhadap jumlah parasitemia dan monosit dalam darah mencit (Mus musculus) yang diinfeksi Plasmodium berghei. Penelitian yang dilakukan merupakan penelitian eksperimen murni (true experiment design) in vivo dengan desain rancangan acak lengkap (completely randomized design). Uji efektivitas ekstrak metanol akar pandan wangi sebagai antimalaria dilakukan dengan konsentrasi 6,5%, 13% dan 26%. Kontrol positif diberi 3,74 mg/mL Dihydroartemisinin-Piperaquin (DHP), kontrol negatif diberikan akuades dan kontrol normal tidak diintervensi Hasil penelitian menunjukkan konsentrasi 6,5%, 13% dan 26% memiliki aktivitas antimalaria dengan menurunkan persentase parasitemia dan meningkatkan jumlah monosit. Kesimpulan dalam penelitian ini ekstrak akar pandan wangi memiliki aktivitas malaria dengan konsentrasi yang paling baik yaitu 26% untuk menurunkan jumlah parasitemia dan meningkatkan monosit.Kata Kunci: Pandanus amaryllifolius Roxb. Antimalaria, Monosit, Plasmodium bergheiABSTRACTMalaria is one of the most common infectious diseases in the world and is the third highest infection in mortality. In Indonesia, eradication of malaria is not maximal because of parasitic resistance to antimalarial drugs and immune system disorders. Monocytes are important effector immune cells in the protection of the cytostatic and cytotoxic pathogenesis of malaria. Pandanus amaryllifolius Roxb. root plant have compounds that can work as antimalarials and immunomodulators. This research aim to determine the effectiveness of the methanol extract of Pandanus amoryllifolius Roxb. as antimalarial to parasitemia and monocytes count of blood mice (Mus musculus) with Plasmodium berghei infection. This study is a true experiment design in vivo with complete randomized design. Methanol extract of Pandanus amaryllifolius Roxb. with concentration 6.5%, 13% and 26% used as antimalarial. Dihydroartemisinin-Piperaquine (DHP) 3.74 mg/mL used as positive control, aquades used as negative control groups and the control group was not intervened. The result of this research show effectiveness as antimalarial in methanol extract of Pandanus amaryllifolius Roxb. with concentration 6,5%, 13% and 26% have antimalarial activity by decreasing percentage of parasitemia and increasing monocyte count. The conclusion of this research is the high antimalarial activity in methanol extract of Pandanus amaryllifolius Roxb. in 26% concreation which could decreased parasitemia precentage and increased monocytes count.Keywords: Pandanus amaryllifolius Roxb, Antimalarial, Monocyte, Plasmodium berghei

The pure compound relatively (85 mg) was isolated from 4.5 kg Brucea javanica (L.) Merr. fruits sample. It was obtained from ethyl acetate fraction as a red-brownish amorphous solid of melting point 202-206 oC. Phytochemical screening of isolate showed positive result of terpenoid group. Based on analysis by UV, IR,1H-NMR and 13C-NMR spectroscopy and by comparison with known related compounds, indicated that isolate is quassinoid compound named Picras 3- en- 21- oat acid, 15-(acetyloxy)-13,20- epoxy-3-(ß-D- glucopyranosyloxy)-11, 12- dihydroxy -2, 16- dioxo -, methyl ester. Cytotoxic test using MTT assay method showed that compound have IC50 9,7 µg/mL.

Abstract

The purpose of this research is to isolate and characterize chemical compound from bark of mangosteen. Bark of mangosteen was macerated with methanol. The extract from that process was fractionated with n-hexane, methylen chloride, and ethyl acetate. Ethyl acetate fraction was separated and purified by vacuum column chromatography, gravitation column chromatography, and preparative thin layer chromatography. The relative pure compound was afforded from ethyl acetate fraction of mangosteen bark (8.5 mg) resulting from 1.5 kg of mangosteen bark. The yellow amorphous powder of compound melts at 114 ~ 116ºC (uncorrected). The purity of compounds was tested by 1 and 2 dimension thin layer chromatography which gave one spot on TLC plate. The ultraviolet-visible (in CH3OH solvent) spectrum showed absorption maximum at 318 nm (sinamoyl group/band I), 258 (shoulder), and 243 nm (benzoyl group/band II). Addition of NaOH caused batochromic shift of band I and band II predicted as two hydroxyl at C-4’ and C-7, respectively. The infrared spectrum displayed absorption bands of OH stretching at  3436 cm-1, C-H stretching at 2920 cm-1, C=O stretching at 1631 cm-1, C-O-C stretching at 1094 cm-1, and C-H aromatics bending at  970-800 cm-1. A molecular ion in the FABMS at m/z 271.36 [M+H] + was consistent for the molecular formula C15H10O5. The 1H NMR spectrum showed characteristic resonances of a flavone. Based on the result of phytochemical test and analysis of the spectrum, it is predicted that the compound belongs to flavone, a kind of flavonoids which has hydroxyl at C-5, C-7, and C-4.

Abstract

Pb (II) merupakan salah satu zat beracun dan berbahaya. Keberadaannya dalam tubuh manusia dapat mengganggu sistem metabolisme tubuh. Penelitian ini bertujuan untuk mengkarakterisasi flavonoid yang diisolasi dari daun mundu (Garcinia dulcis) sebagai pengompleks logam Pb (II). Tahapan penelitian yang dilakukan meliputi persiapan sampel kemudian ekstraksi, isolasi, dan pemurnian senyawa menggunakan metode kromatografi vakum cair (KVC), kromatografi kolom gravitasi (KKG), dan kromatografi lapis tipis (KLT), sedangkan identifikasi senyawa dilakukan menggunakan spektroskopi ultraungu-tampak (UV-Vis) dan inframerah (IR) serta 1H-NMR. Penelitian ini telah berhasil memperoleh 6 fraksi gabungan dari KVC dan 6 fraksi gabungan dari proses KKG. Pada fraksi F4.1 dari KKG dilakukan pemurnian lebih lanjut dengan metode kromatografi lapis tipis (KLT) preparatif sehingga diperoleh 5 isolat. Pada isolat F4.1.3 dilakukan pengujian keberadaan flavonoid dengan uji fitokimia dan hasilnya positif mengandung fenolik dan flavonoid. Selanjutnya isolat tersebut dilakukan pengujian aktivitas pengompleks terhadap logam Pb (II) 100 ppm, 200 ppm dan 300 ppm. Berdasarkan hasil pengujian UV-Vis, isolat F4.1.3 terdapat dua pita pada 287 nm dan 291 nm yang menunjukkan adanya karakteristik senyawa flavonoid. Pergeseran batokromik dari 287 nm dan 291 menjadi 289 dan 293 nm ini setelah penambahan Pb (II) menunjukkan bahwa isolat memiliki kemampuan mengkompleks Pb (II). Hasil analisis spektra inframerah (IR) dan 1H-NMR diduga isolat F41.3 adalah senyawa 5,8,4??trihidroksi-flavan.

Abstract

Flavonoid is one of the phenolic compounds that can complex metals. One of the native plants of Indonesia which has the potential as a metal complexor is the andong plant (Cordyline fruticosa (L.) A.Chev). The isolation process to obtain pure compound are extraction, fractionation, and separation by chromatography. Chromatography method using vacuum liquid chromatography (VLC), gravity column chromatography (GCC) and preparative thin layer chromatography (TLC). This research obtained relatively pure isolate F2.8. The IR (KBr) data on wave numbers of isolate F2.8 were 3430; 2925-2855; 1749; 1609-1512; 1171 and 1100 cm-1.The result of the spectrum 1H-NMR showed flavonoid compound has similar typical spectrum of apigenin compound which showed chemical shift (?H ppm) : 6.85 (1H, s, H-3); 6.29 (1H, s H-6); 6.57 (1H, H-8); 7.03 (2H, d, J = 11.96 Hz, H-3?, H-5?); 8.03 (2H, d, J = 11.72 Hz, H-2?, H-6?). The UV-Vis (CH3OH) spectrum data of isolate F2.8 after the addition of Fe2+ showed a shift at ?max towards a greater direction with a batochromic shift which was caused a decrease in absorbance after the addition of iron (Fe2+) 20 ppm namely: 290 nm; 305 nm with respectively absorbances of 1.62 A; 0.42 A. Based on these data, isolate F2.8 is apigenin which is capable of complexing Fe2+.
