Chemical profiles of primary and secondary essential Oils of palmarosa (Cymbopogon martinii (Roxb.) Wats var. motia Burk.)
Industrial Crops and Products, 2005Co-Authors: B. R R Rao, P. N. Kaul, K V Syamasundar, Sunil RameshAbstract:Natural essential Oils extracted from aromatic crops through steam distillation are extensively used in fragrance, flavour and pharmaceutical industries and in aromatherapy. During steam distillation, a part of the essential Oil becomes dissolved in condensate or distillation water and is lost as this water is discarded. A method was developed to recover the dissolved essential Oil from condensate water. Palmarosa (Cymbopogon martinii (Roxb.) Wats. var. motia Burk., family: Poaceae), an important aromatic grass was used as the test crop. The distillation water of palmarosa mixed with hexane in 10:1 proportion was thoroughly shaken for 30 min to trap the dissolved essential Oil. Hexane was then distilled to yield 'secondary' or 'recovered' Oil. In palmarosa, the 'primary' or 'Decanted' Oil (obtained directly by distilling the crop biomass) accounted for 92% and the recovered Oil accounted for 8% of the total Oil yield. The solvent loss in this process was 4-7%. Experiments conducted in the laboratory with the essential Oil showed that the water solubility of palmarosa Oil ranged from 0.12 to 0.15% at 31??C and 0.15 to 0.20% at 80??C. Hexane recovered up to 97% of the dissolved essential Oil in water. The recovered essential Oil was richer in organoleptically important oxygenated compounds linalool (2.6-3.8%), geraniol (91.8-92.8%) and geranial (1.8-2.0%) compared to the primary Oil. ?? 2004 Elsevier B.V.

Comparative composition of Decanted and recovered essential Oils of Eucalyptus citriodora Hook
Flavour and Fragrance Journal, 2003Co-Authors: P. N. Kaul, K V Syamasundar, Srinivasaiyer RameshAbstract:The chemical composition of Decanted (obtained directly by steam distillation of the leaves) and recovered (extracted from distillation water using hexane) essential Oils of Eucalyptus citriodora were examined. The Decanted Oil was richer in citronellal (70.3%), citronellol (8.8%), citronellyl acetate (1.3%) and β-caryophyllene (2.6%). The recovered Oil was richer in isopulegol (53.0%), borneol (10.0%), menthol (5.3%), neral (6.9%), geraniol (1.4%) and eugenol (4.6%). Citronellal, the major constituent of the Decanted Oil, was absent in the recovered Oil. Copyright © 2003 John Wiley & Sons, Ltd.
