| Abstract: | Borneol and isoborneol, the effective constituent in Chinese Medicine Shuxinping are quantitatively analyzed by GC and GC-MS with hexahydrothymol as an internal standard. By comparison of three extraction methods and four extraction solvents, it is found that ultrasonic extraction method using ethanol as extraction solvent has the highest efficiency. The result shows that the repeatability of GC method and the stability of Shuxinping are perfect. The coefficient of linear correlation for borneol's calibration curve reaches to 1. 000, the average recoveries are between 99. 12% and 101. 4%. |
