[Abstract]
GC retention index of volatile component of Cyperus rotundas was studied by capillary Gas Chromatography, and the standard Gas Chromatographic diagram sad GC retention in-dex spectrum, which provide a new identification method for traditional Chinese medicine was established, This method may be used to difiercntiate the genuine C.rotundas from other false or confusion products, The average C V(%)of RI from 37 sets of C.rotundas fro m three different producing areas were 0-0.24 The method possesses well accuracy,comparability and good reproducibility.
