Titre : Analysis of the leaf, rhizome and root oils of two accessions of alpinia calcarata rosc. cultivated at bhubaneswar Type de document : texte imprimé Auteurs : P. K. Rout, Auteur ; S. Sahoo, Auteur ; S. P. Rath, Auteur Année de publication : 2006 Article en page(s) : pp. 398-400 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Alpinia calcarata Zingiberaceae Essential oil composition β -pinene 1–8-cineole α -fenchyl acetate Geraniol Résumé : Alpinia calcarata collected from Berhampur (Orissa) and Bangalore (Karnataka) India were multiplied and grown in an experimental garden in Bhubaneswar. The oils obtained from the leaves, rhizomes and roots of both the accessions were analyzed by combination of capillary GC and GC/MS. In all 85 constituents were identified constituting 81–98% of oil. It was found that the leaf oils of both the accessions were quite similar, the major components being α-pinene (5.3–6.3%), camphene (3.5–6.0%), β-pinene (16.8–29.1%), 1,8-cineole (21.9–24.7%), camphor (4.9–8.0%), (E)-methyl cinnamate (2.0–2.9%) and carotol (1.3–6.1%). In the rhizome oil of the Bangalore accession, geraniol was the major component, but it was not detected in the oils from the Berhampur accession. In the rhizome oil the major components were α-pinene (1.9–2.3%), camphene (4.4–5.5%), β-pinene (2.0–4.1%), 1,8-cineole (21.2–25.7%), camphor (2.6–4.6%), α-fenchyl acetate (10.2–29.2%) and geraniol (0–34.3%), while the root oil had β-pinene (3.54.7%), camphene (9.0–12.3%), 1,8-cineole (15.1–15.5%), α-fenchyl acetate (39.1–45.2%) and geraniol (0–4.2%) as the major constituents.

Titre : Composition of absolutes of jasminum sambac L. flowers fractionated with liquid CO2 and methanol and comparison with liquid CO2 extract Type de document : texte imprimé Auteurs : P. K. Rout, Auteur ; S. N. Naik, Auteur ; Y. R. Rao, Auteur Année de publication : 2011 Article en page(s) : pp. 398-406 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Jasminum sambac Oleaceae Liquid CO2 fractionation extract Concrete composition Absolute Linalool Benzyl acetate (E,E)-α -farnesene (Z)-3-hexenyl benzoate Index. décimale : 646 Résumé : Absolutes obtained by fractionation of the pentane extract (concrete) of flowers of Jasminum sambac L. with cold methanol or liquid CO2 were compared. Direct extraction of flowers with liquid CO2 gave a relatively fat-free and superior product in 0.44% yield. It was found that the CO2 method of fractionation of pentane extract is a practical process providing an organoleptically superior product, though the product is not totally free from waxy substances. (E,E)-α-Farnesene and (Z)-3-hexenyl benzoate, along with compounds like indole, methyl anthranilate and methyl jasmonate, responsible for high diffusivity of the jasmine fragrance, have been obtained with improved recoveries in the CO2 fractionated concrete.
