Bio-oil is often extracted from biomass using liquid solvent or supercritical carbon dioxide. However, extraction these methods has several disadvantages. In this study, expanded hexane with dioxide examined as a new solvent. The objective of study to develop technique for the bio-oil dioxide; rice bran used raw biomass. was carried out at 25— 27°C, 5.0—5.3 MPa, and 0.78—0.94 mole fraction in h...

Abstract The objective of this study was to characterize the chemical composition in extracts atemoya (var. Thompson) seed oil by spectrometric methods. following extraction methods were performed: using hexane, mechanical a press, and partitioned extraction. each analysed gas chromatography-mass spectrometry (GC-MS), more than 100 compounds identified. major constituents hexane (Z)-hexadec-9-e...

BACKGROUND The plant Launaea procumbens belongs to the family Asteraceae and traditionally used in the treatment rheumatism, kidney, liver dysfunctions and eye diseases. In the present study Phytochemical analysis and fractions of methanolic extract of L. procumbens leaves were tested in vitro for their cytotoxicity. OBJECTIVES Phytochemical analysis and cytotoxic activity of methanolic extra...

Star anise (Illicium verum) is widely used as a medicinal herb and spice. The extracts, essential oil oleoresin, can be produced by hydro-distillation steam distillation, while solvent supercritical fluid extraction to extract oleoresin. In this work, the star distilled obtain oil, subsequently, its residue extracted get Whole grounded fruit for 8, 12, 16, 20, 24 hours, thus highest yield obtai...

Curcumin, the yellow coloring pigment of turmeric is produced industrially from turmeric oleoresin. The mother liquor after isolation of curcumin from oleoresin known as curcumin removed turmeric oleoresin (CRTO) was extracted three times with n-hexane at room temperature for 30 min to obtain turmeric oil. The turmeric oil was subjected to fractional distillation under vacuum to get two fractio...

Fluoride-polluted navel orange leaves, Citrus sinensis (Linn.) Osbeck, were fractionated into the subcellular components in hexane/carbon tetrachloride mixtures having various densities. Fluoride was determined at each fraction. Analyses were also made for the subcellular distribution of chlorophyll, nitrogen, and DNA to assess the extent of cross-contamination of each component. The fraction c...

Methanolic extracts of rice hulls with or without far infrared (FIR) irradiation were sequentially fractionated with solvents (hexane, chloroform, ethyl acetate, butanol, and water), and antioxidant activities of the fractions were analyzed for total phenol contents (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging capability, reducing power, and antioxidant potency. Yield of chlor...

Tombili plant ( Caesalpinia bonducella ) belongs to the family of Fabaceae . The seed extract tombili has been empirically used as a traditional medicine. purpose this research was fractionate and test their antioxidant cholesterol lowering activities. Extraction made into fractions using n -hexane, ethyl acetate, methanol solvent. chemical compound acetate fraction analyzed liquid chromatograp...

Honey is a natural ingredient that Indonesian people widely use to maintain healthy body. One of the benefits honey as an antioxidant. This antioxidant activity influenced by producing bee, source plant, and area. study aims determine Sumbawa originating from NTT. samples were collected dried using freeze-drying method then macerated with 70% ethanol. The viscous extract obtained was fractionat...
