ISOLATION OF AROMATIC AND MEDICINAL COMPOUNDS FROM ISODON NILGHERRICUS (BENTH.) H. HARA – AN ECONOMIC ASPECT

The secondary metabolites being defensive function in plants, the men also thought of using same to defend the chronic diseases by crud drugs or with some organic aromatic molecules. The phenyl groups and other functional groups are bonded together, forming aromatic organic molecules. These molecules are used in perfumes and medicines. The qualitative and quantitative aromatic and medicinal compounds isolation was carried out from Isodon nilgherricus (Benth.) H. Hara. The qualitative analysis was carried out by various solvent extraction tests, and quantitative analysis was carried out by GC-MS technique. The qualitative analysis of essential oil showed the presence of Butenal <2-methyl-> which has 100% area covered with a retention time of 1.905. Quantitative analysis led to the identification of 32 different compounds from total 38 different peaks. The predominant components of the oil detected were Butyl pentanoate, pentanoic acid (13.60%), Norbornene-2-methonol<endo-5->, bicycle (2.2.1) hept-5-ene-2 methanol (1R-endo) with 5.25% concentration. It was followed by Ethyl 3-hydroxyhexanoate, hexanoic acid, 3, hydroxy-ethyl easter (4.45%), Isobutyl angelate (3.10%), Butanoic acid (2.45%). Butyl pentanoate is the major compound that gives the aroma in this plant.
