Abstract:
Objective: To establish the method of fingerprint analysis on volatile oil of Pogostemon cablin (Blanco) Benth. cultivated in Shipai country by GC MS, and to study the main characteristic components. Methods: The main components of the volatile oil of Pogostemon cablin (Blanco) Benth. from different colletion time in Shipai country were determined by GC MS, and compared with the volatile oil of “Gaoyao huoxiang” and “Hainan huoxiang” cultivated in the same GAP plots. Results: RSD of precision and reproducibility and stability is in the range of 5%, and the main components of the volatile oil of “Shipai huoxiang” from different collection time are nearly similar, and the content of Pogostone increases along with cultivation time, and the content of Pogostone and Patchoulic alcohol are significantly differences compared with the “Gaoyao huoxiang” and “Hainan huoxiang”. Conclusion: The method is reliable, accurate and can be used for quality control of volatile oil of Pogostemon cablin (Blanco) Benth.
