Growth and characterization of L-phenylalanine

L-Phenylalanine (C9H11NO2), having the morphology of spherulitic needles, an amino acid constituent, responsible for brain nutrition is crystallized in silica gel of pH 6.0 by single diffusion method in a period of 30 minutes. The grown crystals were characterized by X-ray powder diffraction, Fourier Transform infrared spectroscopy and Visible Ultraviolet spectroscopy. (C) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
