Abstract

Characteristic organic geochemistry of crude oil Juwata, Tarakan, North Kalimantan provide information about the depositional sedimental environment and maturity of the oil. Crude oil was extracted with n-hexane (50: 2) for 24 hours to separate the crude oil with asphaltene, and if precipitation does not separate perfectly then centrifuged. Extracts were then refractionated using column chromatography according to the methods McCharty base. Fractionation results are obtained in the form of the neutral fraction, the acid fraction and polar fraction. Neutral fraction separated with KLTP method and aliphatic fraction and aromatic fractions. Aliphatic fraction subsequently analyzed by GC-MS. GC-MS analysis aliphatic fraction of n-alkanes in the form of compounds, and hopane, bikadinancompounds. The pattern of distribution of n-alkanes which consists of a range of C-17 to C-33. Carbon distribution with a range of C-21 to C-33 is dominating compared to the C-17 to C-20. This distribution pattern indicates the source of organic matter from terrestrial land wax component derived from higher plants. Hopane presence of compounds in crude oil aliphatic fractionsJuwata Tarakan, North Kalimantan analyzed by fragmentogram m/z = 191. Hopane biomarker provide that information during the sedimentation stage diagenesis these compounds are degraded and stereochemical changes towards a stable isomer form, configuration changes 17α (H), 21β (H) during the process of diagenesis to a stable isomer which is 17 α (H), 21β (H) or 21β (H), 17 α (H) indicates that oil comes from the old sediments. Biomarka bikadina identified according fragmentogram m/z = 191 multiple ion fragment m/z = 109.191, 369, 397 and ion molecular m/z = 412 showed the characteristic fragment bikadinna compound. Biomarka bikadina give information influx of organic material terrestrial region. The compounds showed crude oils biomarker Juwata Tarakan, North Kalimantan derived from terrestrial depositional environments.

Abstract

The free radical scavenging activity of Mangiferaindica L. Leaves had been performed. The methanol extract showed the highest 2,2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) free radical scavenging activity among other extracts. Bioassay guided fractionation was performed and yielded three isolated compounds. Their structures were identified as mangiferin (1), friedelin (2) and lupeol (3). Mangiferin exhibited free radical scavenging activity, with an IC50 value of 12.12 µg/mL in vitro.

Abstract

Characteristic of organic geochemistry (biomarker) gives information about environment of coal. Coal was extracted by dichloromethane:methanol (93:7) for 72 h. Extract was obtained then fractionated by its polarity using column chromatography McCharty method. Subsequently, it was extracted to obtain neutral, acid and polar fractions. Neutral fraction was separated by KLTP methode and the extract were fractionated into hydrocarbon component which consist of Aliphatic and Aromatic compounds. The obtaining compounds were characterized by GCMS. Result of GCMS analyzed in Aliphatic fraction shown presence of n-alkane and derivate of terpen.These compounds are considered as important derivatives from natural products of higher plants and some compounds were expected formed by bacteria

Abstract

Wondama coal were subjected to solvent extraction and aromatic hydrocarbon fractions obtained by thin layer chromatography with n-hexane as eluent. Aromatic fractions identified by Gas Chromatography-Mass Spectroscopy (GC-MS). Aromatic seskuiterpenoids, diterpenoid and triterpenoids were found in Wondama coal. This composition illustrates sources of organic matter derived from terrestrial higher plants.
