“…From the above remarkable differences, it is evident that the market oil is either synthetic or reconstituted. Analysis of the various Indian reports [6][7][8][9][10][11] revealed that 2-phenyl ethyl methyl ether was the main constituent (65.6-75.4%), [6][7][8][9][10][11] followed by terpinen-4-ol (11.7-20.9%) [7][8][9][10][11] in the natural Kewda oil. In contrast to the above, Nigam et al 6 in 1992, reported 2-phenyl ethyl alcohol (16.2%) as the second major constituent.…”

“…The compounds were identified by comparing their retention indices of peaks on the BP-1 column with literature values, [4][5][6][7][8][9][10][11] computer matching against the library spectra build up using pure substances and components of known essential oils, and finally confirmed by comparision of mass spectra of peaks with published data. [12][13][14][15][16] Relative amount of individual components are based on peak areas obtained without FID response factor correction.…”

The chemical composition of the essential oil obtained by hydrodistillation of staminate inflorescences of kewda (Pandanus odoratissimus L.) has been compared with the kewda oil from the local market. Both the oils were subjected to high-resolution GC and GC-MS, which resulted in the identification and quantification of 85 and 59 components, amounting to 98.7% and 98.6% of the total oils, respectively. The major components of the hydrodistilled kewda oil were 2-phenyl ethyl methyl ether (37.7%), terpinen-4-ol (18.6%), α-terpineol (8.3%) and 2-phenyl ethyl alcohol (7.5%), whereas the major constituents of kewda oil from the local market were 2-phenyl ethyl alcohol (33.2%), 2-phenyl ethyl methyl ether (16.1%), benzyl benzoate (11.0%), viridine (8.8%) and germacrene B (8.3%).

“…Kewda shrub grows up wild in Ganjam district, Odisha, and its flower processing is a flourishing village industry generating several thousands of man‐days of work . Although found to spread out to several places in India, the plentiful and gregarious growth is concentrated along the coastal belt of Ganjam district contributing 85–90% of country's kewda essence production . It is estimated that kewda grows in about 5000 ha area, and around 40 million flowers costing more than $5 million are processed annually in about 70 coastal villages of this district.…”

“…In our previous study, the isolation and chemical composition of the kewda essential oil had been studied . The principal compounds identified were phenylethyl methyl ether (PME) (65–77%), terpinen‐4‐ol (TOL) (13–18%), α ‐terpineol (ATL) (1–3%), phenylethyl alcohol (PEA) (0.1–0.5%) and 1,8‐cineole (0.1–0.5%).…”

Kewda (Pandanus fascicularis Lam) essential oil was enriched with phenylethyl methyl ether (65-77%), terpinen-4-ol (13-18%) and α-terpineol (1-3%), which were definitely soluble in distillation condensate. The solubility of phenylethyl methyl ether, terpinen-4-ol and α-terpineol in water were more than 1000 ppm. Adsorption performance of single-solutes and multi-solutes over Amberlite-resins and Indion-resins were elucidated. XAD-4 and Indion 1014 MN-2 were most suitable because of their higher loading capacities of 2.2-3.2 mmol g À1 and 2.3-3.6 mmol g À1 , respectively. Temkin adsorption isotherm was best fitted to the experimental results. Adsorption was followed Pseudo-second order, Ritche's-second order and Elovich's equation to validate the kinetics of chemisorption. Column breakthrough results revealed that the water soluble essential oil was recovered from the distillation condensate through a resin bed. Then the adsorbed solutes were desorbed from the resins with elution in ethanol to achieve complete recovery of high value essential oil from the distillation condensate.

Extraction of kewda (Pandanus fascicularis Lam.) flowers with hexane: composition of concrete, absolute and wax

Extraction of male spadices of kewda (Pandanus fascicularis Lam.) flowers with hexane furnished a waxy extract, the so-called 'concrete'. Treatment of the extract with methanol gave a reddish oily residue ('absolute') with a smell strongly reminiscent of the aroma of kewda flowers. Concrete, absolute and separated waxes were analysed by GC and GC-MS. The methanol-soluble portion contains considerable quantities of fatty acids and their methyl esters, which function as a fixative for the volatile fragrant components of the extracts. While the recoveries of the oxygenated compounds terpinen-4-ol and α α α α α-terpineol are less than the amounts usually obtained through hydrodistillation, the major component, 2-phenyl ethyl methyl ether, and non-polar compounds, α α α α α-thujene, sabinene and its hydrate, have been obtained in larger amounts.
