Study on characteristic fingerprint of volatile oil of Pogostemon cablin (Blanco) Benth by GC-MS / 中成药

ABSTRACT

Objective: To establish the characteristic fingerprint of volatile oil of Pogostemon cablin (Blanco) Benth.Methods: The main components of 21 samples were determined by GC MS. Results: ? Patchoulene, ? Elemene, cis Caryophyllene, trans Caryophyllene, seychellene, ? Guaiene, ? Patchoulene, ? Guaiene, unidentification component A, patchoulic alcohol, pogostone were determined in all samples, and the relative content of 11 components add up to 80 percent. Compared with the samples produceds in Gaoyao and Hainan, Shipai samples were significantly differences.Conclusion: The retention time and relative content of 11 components bulidup the characteristic fingerprint of volatile oil of Pogostemon cablin (Blanco) Benth, it can be used for quality control and identification to Pogostemon cablin (Blanco) Benth.
