The use of13C satellites in the proton NMR spectra of oriented systems for the determination of molecular structure

Lignin was isolated from wet Banana pseudostem with 2% NaOH solution by boiling. The isolated lignin was treated with urea and called uro-lignin. IR, Mass and NMR spectra of urolignin were taken to determine its molecular structure. DOI: 10.3329/jbas.v33i2.4106 Journal of Bangladesh Academy of Sciences, Vol. 33, No. 2, 227-229, 2009

Hydroxamic Acid Derivatives

The electronic absorption spectra of some hydroxamic acid oxime derivatives and Schiff's base derivatives in polar (ethanol) and nonpolar (CCl4) solvents, as well as in some other organic solvents of different polarities, were investigated; the variation of absorbance with pH was utilized for the determination of pKa, and Δ G* values. The important bands in the IR spectra as well as the main signals of the NMR spectra are also discussed in relation to the molecular structure.

Heavy Atom Method

The crystal and molecular structure of the title compound (C8H16N2NiS4) was solved by the heavy atom method and the structure was refined anisotropically to a final R factor of R = 0.029 (wR = 0.037) for 715 observed reflections. The crystal is monoclinic, space group P21/c with a = 948.3(2), b = 776.9(2), c = 1 167.4(2) pm, β = 125.14(2)°, Z = 2. The molecule contains two four-membered NiSCS rings of approximately planar configuration with the Ni atom situated at a centre of symmetry. The molecules are arranged in chains along the c-axis of the unit cell.

rel(1S,4S,5R)-3,3,5-Trimethyl-4-[( 1E)-3-oxo-1-butenyl]-4,5-epoxy-cyclohexyl-O-β-D-glucopyranoside (I) was isolated from the aerial part of Veratrum lobelianum BERNH. The structure was derived mainly from detailed analysis of 1H and 13C NMR spectra of its acetylated derivative II. Compound I has been already reported under the name icariside B2in Epimedium grandiflorum MORR. var. thunbergianum (MIQ.) NAKAI.
