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 mm I.D.) coated with DB-1701 (df 0.25 micron). The Py-HRGC data were analysed by non-linear mapping PaRe. The results showed that Mai Dong samples could be classified into two categories: Ophiopogon japonicus (L.f.) Ker-Gawl (included in the Chinese Pharmacopoeia) and Liriope spicata.
