Fucales are an order within the Phaeophyceae that include most of the common littoral seaweeds in temperate and subtropical coastal regions. Many species of this order have long been a part of human culture with applications as food, feedand remedies in folk medicine. Apart from their high nutritional value, these seaweeds are also a well-known reservoir of multiple bioactive compounds with great industrial int...
Resveratrol (RSV) is a functional ingredient with numerous bioactive properties, but precautions should be considered in the formulation of liquid food products due its poor solubility and bioavailability. In this context, cyclodextrin complexes are a viable solubilisation strategy, already applied in delivering hydrophobic compounds [1]. This study aimed at evaluating the use of and -cyclodextrin complexes wit...
Fisetin is a natural antioxidant with a wide range of nutraceutical properties, including antidiabetic, neuroprotecting, and suppression or prevention of tumors. The present work describes the preparation of a water-soluble, solid inclusion compound of fisetin with gamma-cyclodextrin (γ-CD), a cyclic oligosaccharide approved for human consumption. A detailed physicochemical analysis of the product is carried ou...
A novel beta-cyclodextrin (beta CD) inclusion compound was prepared using 4-phenylpyridine-N-oxide (PPNO) as the organic guest. The inclusion compound, beta CD.PPNO, was characterised both in solution and in the solid state using numerous techniques. H-1 NMR in aqueous solution allowed the determination of a 1 : 1 stoichiometry and an association constant of 164 +/- 21 M-1. Powder and single-crystal X-ray diffr...
The complex [Ru[9]aneS3(pdon)Cl]Cl (pdon = 1,10-phenanthroline-5,6-dione) was readily obtained from the stoichiometric reaction of Ru[9]aneS3(dmso)Cl2 with pdon. Recrystallisation in ethanol using salicylic acid as a co-crystallisation helper afforded single-crystals suitable for the collection of X-ray diffraction data which afforded a reasonable structural description. Two different kinds of molecular carrier...
The complexes [(eta(5)-C5H4-CO-R)Mo(CO)(2)(eta(3)-C3H5)] [R = OH (1), Phe OMe (2)] have been examined as guests for the cyclodextrin (CD) hosts beta-CD and heptakis(2,3,6-tri-O-methyl)-beta-CD (TRIMEB), and the resultant inclusion compounds have been characterised in the solid state by elemental and thermogravimetric analyses, powder X-ray diffraction, C-13{H-1) cross-polarisation (CP) magic angle spinning (MAS...
The complex [Ru[9]aneS(3)(pdon)Cl]Cl (pdon = 1,10-phenanthroline-5,6-dione) was readily obtained from the stoichiometric reaction of Ru[9]aneS(3)(dmso)Cl-2 with pdon. Recrystallisation in ethanol using salicylic acid as a co-crystallisation helper afforded single-crystals suitable for the collection of X-ray diffraction data which afforded a reasonable structural description. Two different kinds of molecular ca...
The homodinuclear europium(III) -diketonate complex [Eu-2(bta)(4)(pypzCH(2)COO)(2)] (1) {bta = 1-benzoyl-3,3,3-trifluoroacetonate, pypzCH(2)COO = [3-(2-pyridyl)-1-pyrazolyl]acetate} was isolated after recrystallization of the crude product obtained from the reaction of [Eu(bta)(3)(H2O)(2)] with one equivalent of the ligand phenyl[3-(2-pyridyl)-1-pyrazolyl]acetate (pypzCH(2)CO(2)C(6)H(5)). A single-crystal X-ray...
