Abstract:
Object To study comparatively the fingerprint of Pogostemon cablin (Blanco) Benth. in different producing area and investigate the effect of pyrolysis temperature and pyrolysis time on the fingerprint Methods Pyrolysis gas chromatography (PGC) and fuzzy cluster analysis were used Results Both similarity and charecteristics were found in the fingerprint of P. cablin in different producing area. The methodological evalulation showed that this method had a good reproducibility, RSD≤2.75% Conclusion This method is simple, rapid and accurate. It is suitable for the quality control of the Chinese materia medica with the important role of pyrolysis temperature and pyrolysis time
