wheel. Aromatics sources Plant sources Plants have long been used in perfumery as a source of essential oils and aroma compounds . These aromatics are usually secondary metabolites produced by plants as protection against herbivores‚ infections‚ as well as to attract pollinators. Plants are by far the largest source of fragrant compounds used in perfumery. The sources of these compounds may be derived from various parts of a plant. A plant can offer more than one source of aromatics‚ for instance

Through a series of chemical reactions with cheap raw materials beginning with beginning with methyl salicylate and‚ it is a cheaper and more efficient method of making salicylic acid from natural resource of benzene. The purpose of the experiment is to prepare salicylic acid methyl salicylate‚ and compare it to the one already made naturally from benzene to determine any differences

Accepted November 23‚ 2010; Published Online December 14‚ 2010 Methyl ester derivatives of fatty acids were analyzed for the determination of the constituents of Datura seed oil. Gas chromatography coupled to mass spectrometer was used for these analyses. Results delivered that there were saturated as well as unsaturated fatty acids in Datura alba seed oil. Total of 15 different fatty acid components were identified and quantified. Methyl linoleate was found in highest concentration (16.22%) among the

curve‚ corresponding to the above three stages. Reactions (1) and (3) can be indicated by phenolphthalein and that of reaction (2) can be indicated by methyl orange. Stoichiometry confines each of the above pH reactions to react according to a mole ratio of 1 : 1. This means‚ say from equation (2)‚ the number of mole of HCl(aq) determined from the methyl orange titration is equal to the number of mole of NaHCO3(aq). Likewise‚ total number of moles of NaOH(aq) and Na2CO3(aq) in the solution mixture can
