[Studies of penicillins by micro Raman spectroscopy]

The Raman spectra of three kinds of penicillins were obtained and investigated by micro Raman technique. By comparing these Raman spectra, we find there are many differences among them, and it can be used as an important criterion in distinguishing different kinds of penicillins. In this paper, the characteristic Raman peaks of penicillins have been given. In other hand, we find there is no much difference in the Raman spectra of same kind of penicillin, even though different plants produce them. So, the Raman spectra can't be used to make sure whether certain plant produces one sample.
