Application of pyrolysis-high-resolution gas chromatography-pattern recognition to the identification of the Chinese traditional medicine mai dong.

Pyrolysis-high-resolution gas chromatography-pattern recognition (Py-HRGC-PaRe) was used to develop a potential technique for identifying the Chinese traditional medicine Mai Dong. About 1 mg of crude drug powder was pyrolysed in a furnace pyrolyser and the products were directly carried into a gas chromatograph with an FSOT capillary column (30 m x 0.265… (More)
