  • Factors influencing halogenated monoterpene production in microplantlets derived from the red macroalga Ochtodes secundiramea

    Creator:
    Polzin, Jason
    Abstract:
    Halogenated monoterpene production by the red macroalga Octhodes secundiramea was studied-under different levels of nutrient, bromide, vanadium and light delivery. The key products formed were identified as myrcene, betaelemene, the Z and E isomers of l0-bromomyrcene, 3-chloro-10E-bromomyrcene, Apakaocthodene A, and isomers of chloromyrcene and dibromomyrcene. The proposed pathway begins with...

    Tan, Lik Tong
    Abstract:
    This thesis is an account of my investigation on the natural products deriving from various marine algae and has resulted in the discovery of thirteen novel bioactive metabolites. Isolation and characterization of these unique molecules were carried out using different chromatographic techniques and by careful analyses of 1D and 2D...

    Abstract:
    This thesis is an account of investigation on the natural products deriving from various marine algae and has resulted in the discovery of eleven novel bioactive metabolites. Isolation and characterization of these new molecules were carried out using different chromatographic techniques and by analyses of different spectroscopic data, respectively. Using...

  • Natural products from tropical and temperate marine algae

    Creator:
    Bernart, Matthew W.
    Abstract:
    Following surveys of seaweeds in Oregon and the Caribbean, four algal species were selected for study on the basis of their crude extract biological activity or thin-layer chromatographic characteristics. Extracts were fractionated by normal phase chromatography, including high performance liquid chromatography (HPLC). Derivatives (methyl esters, acetates, and benzoates) of natural...
