Solvent Extraction and Characterization of Essential Oil from Allamanda voilacea

Abstract

The objective of this study is extraction and characterization to identify the chemical composition present in the leaves extract of Allamanda voilacea (Apocynaceae family) collected from Pollachi, Tamil Nadu. The extraction process is achieved by solvent extraction method using soxhlet apparatus, followed by characterization using gas-chromatography-(GC-MS) Gas-Mass spectrometry. Iso-propyl alcohol ((CH3)2-CH-OH) was used as a solvent in the extraction process. A total of 21 compounds were extracted from the leaves extract. The major compounds in the extract include Eticyclidine (23.96%), Alpha. Terpineol(17%),1,4-Methano-1H-indene, octahydro-4-methyl-8-methylene-7-(1-methylethyl)-,[1S(1.alpha.,3a.beta.,4.alpha.,7.alpha.,7a.beta.)] (10.96%), Endo-borneol (8.74%),.alpha.-ylangene (7.77%), Benzene,1-chloro-3,5-difluoro-(7.37%), 2,5-di-tert-Butylnitrobenzene (5.46%). Considering the properties of the above compounds, they can be used in perfume and drug industries.
