Characterisation analysis of bio oil generation using Hibiscus cannabinus seeds.
Bio-oil from Hibiscus cannabinus seeds was extracted with four solvents: acetone, benzene, isopropanol, and hexane. Solvent extraction techniques have less oil residue than other methods. The primary factors that influence the extraction processes such as extraction time, particle size, seed ageing, and solvent suitability were optimised to enhance the bio-oil yield. The extracted bio-oil was tested by GC-MS, FTIR, and 1H-NMR. Physicochemical properties (free fatty acid, specific gravity, acid value, calorific value, saponification number, iodine number, etc.) of hibiscus cannabinus oil were also analysed on a dry weight basis. The hexane solvent gave the highest yield (25.37%) followed by acetone (21.32%), Benzene (16.98%), and Isopropanol (14.20%) over 3.5 h. It is also predicted that the cost of Hibiscus cannabinus seed bio-oil per litre is Rs. 230 which is moderately economical Hibiscus cannabinus oil has a calorific value of 39,895 kJ/kg, making it a better fuel choice.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
