Aims: Physico-chemical, Gas Chromatography-Mass Spectrometry (GC-MS) and Cold saponification was carried out on Lannea microcarpa (Wild grape) seed oil with the aim of identifying the quality and quantity of the oil and its suitability in soap production. Study Design: Experimental and instrumental study was done to determine the physicochemical characteristics, fatty acids present in the seed oil and its suitability for soap production. Place and Duration of Study: The study was conducted at the Biochemistry Laboratory, Kebbi State University of Science and Technology, Aliero, Nigeria from May to June, 2014. Methodology: The hexane extract of the sample was obtained by complete extraction using Soxhlet extractor, physicochemical analysis was carried out. A gas chromatography coupled with mass spectroscopy detector (GC-MS) system was used for the qualitative fatty acid determination. Simple cold method saponification was used in producing the soap. Results: The powdered seed (50 g) yielded 59.21±0.01% of the oil. Results from the physicochemical analysis showed the seed oil to be dark purple in colour and partially soluble in water with the acid, iodine, saponification and peroxide values at  16± 0.01 mgKOH/g, 121.6±0.1 gI2/100 g, 231.25±0.02 mgKOH/g,  3.02±0.01 meq H2O2respectively. The relative density and refractive index of the oil are at 0.5983±0.0001 (g/cm3) and 1.43±0.01 respectively. Qualitative GC-MS revealed the following fatty acids; Decanoic acid, Palmitic acid, Stearic acid, Margaric acid, 1-octadecanoic  acid, Oleic and Erucic acid. The soap produced from the seed oil has pH and Foam height, 10.18±0.01 and 105.1±0.1 (cm³) respectively. Conclusion: The present study on seeds of wild grape revealed that the oil is a viable natural product that can be utilized in thefood and cosmetic industry.

The composition of the fatty acids of the extracted seed oil from Sindora glabra was determined by means of gas chromatography-mass spectrometry. And the physicochemical properties of the oil were also analyzed according to the national standards．The results indicated that 14 fatty acid components were identified in seed oil of Sindora glabra，and the content of unsaturated acids was 61.72％，and the main fatty acids were linoleic acid（33.17%），oleic acid（19.80%），Palmitic acid （14.57%），lignoceric acid （5.06%），stearic acid （4.63%），hexacosanoic acid (2.95%), docosanoic acid（2.70%）, pentacosanoic acid (2.17%). The physicochemical indexes were as follows relative density 0.9143，acid value 3.905 mg/g, iodine value 109.01 g/100g, saponification value 154.6 mg/g, and index of refraction 1.4753.

 Objective:The objective of this study is to characterize the phytoconstituents of Tiliacora racemosa Colebr. using gas chromatography mass spectrometry (GC-MS).Methods: Preliminary phytochemical and physicochemical analysis was carried out using standard procedures. GC-MS analysis of methanolic extract was carried out using Thermo GC-Trace Ultra version: 5.0, Thermo MS DSQ with a DB 35MS capillary standard non-polar column and gas chromatograph interfaced to a mass selective detector (MS DSQ II) with Xcalibur software.Results: Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, triterpenoids, steroids, proteins and amino acids, carbohydrates, saponins and coumarin. Quinones, anthraquinones, glycosides and fixed oil were absent. GC-MS analysis revealed the presence of 28 compounds of which quinic acid (retention times [RT]: 15.65) and inositol, 1-deoxy-(CAS) (RT: 19.24) was observed as abundant compounds.Conclusion: The presence of various bioactive compounds confirms the medicinal importance and it’s application for curing various diseases by traditional practitioners. However, isolation and characterization of potential bioactive compounds would lead to drug formulation.

Abundant Fatty Acid

There is evidence that secondary metabolites are involved in the fungal pathogenicity and virulence of Neofusicoccum spp. Fatty acids may also influence the plant–pathogen interaction but, so far, no information is available on their production by species of Neofusicoccum associated with Botryosphaeria dieback, which is a well-known syndrome of several plants with a complex etiology. In the present paper, the production of fatty acids in liquid medium, by strains of N. vitifusiforme and N. parvum associated with declining Sicilian vine plants, was evaluated. Data, acquired via gas chromatography–mass spectrometry (GC/MS), show the presence of linoleic acid as the most abundant fatty acid produced by both examined strains. In addition, the pathogenicity of N. vitifusiforme was tested on 2-year-old grapevine plants of cv. Inzolia.
