[Identification of Ginseng and its counterfeit by laser Raman spectroscopy].

The objective of the present study is to identify Ginseng and its false sample: Anthriscus sylvestris, Radix glehniae and balloonflower root by Laser Raman spectroscopy, second derivative Raman spectroscopy. The structural information of the samples indicated that Ginseng and its false samples contains a large amount of carbohydrates, since some characteristic vibration peaks of the carbohydrates, such 1 640, 1 432, 1 130, 1 086, 942, 483 cm(-'1) can be observed. The characteristic vibration peak of Radix glehniae which arouse at 2 206 cm(-1) in the aman spectra, totally different from the other three kinds of traditional Chinese medicines.
