Abstract：The Gynostemma Pentaphyllum is an important plant for Chinese crude drug. To qualitatively analyse the Gynostemma Pentaphyllum(Thunb) Makino, FTIR and FT-Raman were used to identify the contents of it. The results show, that the trough of each absorption in the picture of FTIR spectrum and the characteristic wave crest of each dispersion in the picture of FT-Raman spectrum had parallelism at their position, their relation pairs with each other. This is useful for the further on-line quantitative analysis and quality control of the Gynostemma Pentaphyllum(Thunb) Makino. This approach provide a quickly and accurately determination method of crude drug with out extraction and separation.
