Spectral Data Analysis and Identification of L-Methyldopa

OBJECTIVE To identify the structure of L-methyldopa.METHODS The structure of L-methyldopa was analyzed by means of ultraviolet spectrum,infrared spectrum,1H-NMR,13C-NMR and mass spectrum et al.RESULTS Red shift took place in 0.1 mol·L-1 of sodium hydroxide solution,IR spectrum showed there were hydroxyl,amino,carbonyl and phenyl groups in the structure,the molecule consists of 10 carbons and the m/z of molecular ion was 211.CONCLUSION The ways as mentioned above can be used for the identification of L-methyldopa.
