ABSTRACT
[Objective] To compare the difference of fingerprints of Pogostemon cablin (Blanco) Benth. from different places of origin. [Methods] The chemical components of Pogostemon cablin (Blanco) Benth. from 6 places of origin were detected by thin-layer chromatography. [ Results ] The thin-layer chromatogram of volatile components of Pogostemon cablin (Blanco) Benth. from different places of origin was similar. The contents of methanol-extract and petroleum-ether-extract from Pogostemon cablin (Blanco) Benth. planted in Gaoyao, Guangdong differed greatly from those in other places of origin, which can be used to identify the herb of Pogostemon cablin ( Blanco) Benth. from Gaoyao, Guangdong. [Conclusion] Thin-layer chromatographic fingerprints can be used as the parameter to differentiate Pogostemon cablin (Blanco) Benth. from different places of origin.
