Abstract

Chemical isolation and identification of root bark of Calophyllum soulattri Burm. f. have been conducted. Isolation was conducted by maceration with ethyl acetate as solvent. Ethyl acetate extract was separated and purified by vacuum liquid chromatography and flash chromatography which was guided by thin layer chromatography to obtain yellowish white solid. Isolated compounds were determined by spectroscopy methods such as UV, FTIR, 1H NMR, 13C NMR, DEPT, HSQC, HMBC and were compared to the references. Based on the analysis result it’s known that the compounds are the mixture of β-sitosterol and stigmasterol.

Abstract

The purpose of this research was to evaluate antibacterial activity of Neem (Azadirachta indica A. Juss) leaves fraction against some pathogenic bacterial and to identificate the most active fraction. Leaves powder of Neem was macerated with ethanol and factionated by vacuum liquid chromatography using hexane, ethyl acetate and ethanol as eluent, respectively. The antibacterial activity of the fraction was evaluated by diffusion method, then the most active fraction of antibacterial was evaluated by zone of inhibition. The most active fraction of antibacterial was evaluated for Minimum Inhibitory Concentration (MIC) and equivalent value, compared with amoxicillin and chloramphenicol, then identified using phytochemical screening and Gass Chromatography-Mass Spectroscopy (GC-MS).The fraction of Neem leaves fractionated by vacuum liquid chromatography had antibacterial activity againstStaphylococcus epidermidis, Bacillus cereus, and Shigella flexneri. The ethyl acetate fraction showed the most active fraction of antibacterial against all bacterial tested. Ethyl acetate fraction had MIC 0.075% againstStaphylococcus epidermidis 0.05% against Bacillus cereus and Shigella flexneri. The antibacterial activity of ethyl acetat fraction compared to amoxicillin was 0.01% for S. epidermidis, 0.02% for B. cereus, and 0.02% for S. flexneri. Then compared to chloramphenicol was 0.04% for S. epidermidis, 0.02% for B. cereus, and 0.06% for S. flexneri. The result of GC-MS showed that the ethyl acetate fraction contained palmitic acid, ethyl linoleolate, stearic acid, trans-phytol, DOP (di octyl phthalate), and suggested 1 class of compound fatty acid and 5 classes of compound triterpenoids.

Abstract

Curcuma soloensis Val. is a family plant Zingiberaceae and is known as "temu gelnyeh". This plant has been used as a medicinal plant but has not been widely reported about its chemical components. Therefore, this study was carried out to isolation and identification of the chemical components of the C. soloensis Val. rhizome. Isolation was done by extraction, fractionation, and purification. The fractionation and purification of the compound were carried out using chromatography methods. The identification of the compound was determined by spectroscopic methods including 1D-NMR (1H NMR, 13C NMR) and 2D-NMR (HSQC, HMBC). Based on NMR spectra data analysis and compared with literature, the compound obtained yellow liquid was ar-turmerone (2-methyl-6- (4-methylphenyl) hept-2-en-4-on) which was a terpenoid sesquiterpene. Ar-turmerone is the first compound that found from Curcuma soloensis Val. rhizome.

Abstract

The isolation triterpenoid from Nyamplung (Callophyllum inophyllum, Linn.) leaves has been conducted. The isolation was employed by maceration using ethanol as solvent and liquids extraction using ethyl acetate. Ethyl acetate extract was partitioned successively using nonpolar solvent with hexane, dichloromethane, and diethyl ether, respectively. The diethyl ether extract was purified by column chromatography. The isolated compound of fraction D1 was obtained as white solids crystal with yield of 0.0035%. The isolated compound was determined based on the FTIR, 1HNMR, 13CNMR, HSQC, and HMBC spectra. The isolated compound was identified as 28-hydroxy-3-friedelanone.

Pada laporan ini kami melakukan isolasi dan identifikasi senyawa kimia minyak atsiri pada bagian buah tumbuhan Piper. Isolasi minyak atsiri buah Piper dilakukan dengan destilasi air menggunakan destilasi Stahl dan analisis komposisi kimia dengan kromatografi gas-spektroskopi masa (GC-MS). Kandungan minyak atsiri buah sirih hijau (Piper betle) 1,4% (v/b), cabe jawa (Piper retrofractum) 1% (v/b), dan buah kemukus (Piper cubeba) 1,7% (v/b). Hasil analisis GC-MS menunjukan kandungan utama minyak atsiri adalah senyawa golongan monoterpen, seskuiterpen dan fenil propanoid. Kandungan utama minyak atsiri buah sirih hijau (P. betle) adalah eugenol (12,36%), isokaryofillena (9,55%) dan β-selinena (8,09%), sedangkan komponen utama buah cabe jawa (Piper retrofractum) adalah isokaryofilen (8,88%), β-bisabolen (7,01%) dan zingiberen (6,32%), dan minyak atsiri buah kemukus (Piper cubeba) adalah spathulanol (27,05%), sativen (8,73%) dan germakren D (7,50%).
