Extraction And Gcms Analysis Of Oil From Red Cocoyam Peel (colocasia esculenta)

Abstract

Extraction of oil from red cocoyam peel has been carried out using the cold  extraction method, with a reagent n-hexane as the extraction solvent The GC-MS was used to identify the components in the oil after extraction, the components that was found in the oil include, 1,3,5- trimethy benzene at a retention time of (2.844)min with a peak of 3.342%, n-hexadecanoic acid at a retention time of(7.250)min with a peak of 26.395%, 9,12-octadecadienoic acid at a retention time of (7.685)min with a peak of 2.036%, 1,1-dimethyl hexadecenoate at a retention time (7.794)min with a peak of 2.013%,9-octadecenoic acid with a retention time (8.023)min with a peak of 44.142%, 9,12,15-octadecatrienal at a retention time (8.154)min with a peak of 2.819%, Butyl 9,12-octadecadienoate at a retention time (8.555)min with a peak of 7.395%, squalene at a retention time of (10.151)min with a peak of 1.417%, Ergosta-5,22-dien-3-ol at a retention time of (15.879)min  with a peak of 4.482%, 5-cholestene-3-ol,24-methyl at a retention time of (16.714) with a peak of 2.617%, 9,19-cyclolanost-24-en-3-ol at a retention time of (18.368) with a peak of 3.340%. and these components were found to be useful in pharmaceuticals, industries and cosmetics. This study contributes to the importance of sustainable utilization of agricultural byproducts and highlights the potential of red cocoyam peel as a valuable resource for the production of bioactive compounds with diverse industrial applications.
