  • aromatic plants of tropical central africa part xlix chemical composition of essential oils of the leaf and rhizome of Aframomum giganteum k schum from gabon
    Flavour and Fragrance Journal, 2004
    Co-Authors: Huguette Agnaniet, Chantal Menut, Jeanmarie Bessiere

    Abstract:

    The chemical composition of the essential oils obtained by hydrodistillation of the leaves and rhizomes of Aframomum giganteum K. Schum grown in Gabon were investigated by GC–FID and GC–MS. The major compounds in the leaf oil were found to be cis-pinocamphone (54%) and pinocarvone (10.1%), while the essential oil from the rhizomes is dominated by sesquiterpenes, namely β-caryophyllene (10.5%) and their oxygenated derivatives (40%). The antioxidant and the antiradical activity of both samples were evaluated. Copyright © 2004 John Wiley & Sons, Ltd.

  • aromatic plants of tropical central africa xxxviii chemical composition of the essential oils from four Aframomum species collected in cameroon 1
    Journal of Essential Oil Research, 2002
    Co-Authors: P Amvam H Zollo, R Abondo, L Biyiti, Chantal Menut, Jeanmarie Bessiere

    Abstract:

    Abstract The essential oils isolated by hydrodistillation from the leaves or seeds of Aframomum citratum (Pereira) K. Schum., Aframomum hanburyi K. Schum., A. letestuanum Gagnepain and A. pruinosum Gagnepain (Zingiberaceae) grown in Cameroon were analyzed by GC and GC/MS. The leaf oils obtained from A. citratum and A. hanburyi were characterized by being rich in monoterpene hydrocarbons, dominated by pinenes. The major volatile components from seeds of the four species were oxygenated components belonging to the acyclic terpene class, such as geraniol (70.0%) in the case of A. citratum, (E,E)-farnesol (27.3%) and linalool (19.0%) for A. hanburyi, while A. letestuanum and A. pruinosum contained a main proportion of (E)-nerolidol (67.0% and 91.7%, respectively) in their seeds oils.

  • aromatic plants of tropical central africa xii fruit essential oil of Aframomum pruinosum gagnepain a potential source of e r nerolidol
    Journal of Essential Oil Research, 1994
    Co-Authors: Chantal Menut, P Amvam H Zollo, R Abondo, G Lamaty, Jeanmarie Bessiere

    Abstract:

    ABSTRACT The essential oils obtained from seeds and leaves of Aframomum pruinosum Gagnepain from Cameroon have been analyzed by GC and GC/MS. Both samples are completely different; while the leaf oil contains almost similar percentages of mono- and sesquiterpenoids (β-pinene, 31.4%; β-caryophyllene, 25.8%), the fruit oil is characterized by more than 90% of (E)-(R)-nerolidol.

  • Aframomum stipulatum gagnep k schum and Aframomum giganteum oliv hanb k schum as aroma tincto oleo crops resources essential oil fatty acids sterols tocopherols and tocotrienols composition of different fruit parts of congo varieties
    Journal of the Science of Food and Agriculture, 2013
    Co-Authors: Adolphe Christian Ngakegnilimbili, Bachar Zebib, Muriel Cerny, Gouolally Tsiba, Arnold Murphy Elouma Ndinga, Zephirin Mouloungui, Isabelle Fourastier, Jeanmaurille Ouamba

    Abstract:

    BACKGROUND: Today, few known plant species provide both an essential oil (EO) and a vegetable oil (VO). Seed and husk of two Aframomum species were investigated and compared in terms of EO, fatty acids, tocopherols, and tocotrienols.

    RESULTS: EO yield reaches 15.3 g kg−1 in the seeds and 3.2 g kg−1 in the husks, while VO yield is 180.0 g kg−1 in the seeds and 25.0 g kg−1 in the husks. β-Pinene, 1,8-cineol, α-selinene, terpine-4-ol, linalool, myrtenal and β-caryophyllene are the major compounds of seed and husk EO. Fatty acid analysis of two Aframomum species shows that oleic, linoleic, and palmitic acids were the major compounds of VO. Total sterol contents reached 4.3 g kg−1 in seed VO and 8.5 g kg−1 in husk VO. An appreciable amount of tocopherols (0.52 g kg−1) was found in seed VO.

    CONCLUSION: The seed and husk oil of A. stipulatum and A. giganteum fruits are rich sources of many bioactive constituents such as fatty acids, sterols, tocopherols and tocotrienols. These tropical wild fruits can be considered as new Aroma Tincto Oleo Crops (ATOC) resources that contain both EOs and VOs. Copyright © 2012 Society of Chemical Industry

  • chemical composition of essential oils from aerial parts of Aframomum exscapum sims hepper collected in guadeloupe french west indies
    Flavour and Fragrance Journal, 2006
    Co-Authors: M Couppe A De K Martin, H Joseph, Sylvie Bercion, C Menut

    Abstract:

    Chemical composition of essential oils obtained by hydrodistillation of leaves, stems, pulp and seeds of fruits of Aframomum exscapum (Sims) Hepper grown in Guadeloupe was investigated by GC and GC–MS. Forty-four volatile compounds were identified, among which 1,8-cineole was the main constituent in all parts of the plant (47–86%). These analytical data confirm that the species from Guadeloupe is not Aframomum melegueta (Rosc.) K. Schum. as initially claimed by local botanists. Copyright © 2006 John Wiley & Sons, Ltd.
