ABSTRACT
OBJECTIVE:
To study the techniques of organic solvent extraction method and supercritical CO2 extraction for extracting Mosla chinensis Maxim volatile oil (MCMVO), and to analyze its chemical compositions.METHODS:
Organic solvent extraction method and supercritical CO2 extraction were used to extract the oil and GC-MS was used to analyze its chemical compositions.RESULTS:
The best extraction techniques of organic solvent method to extract volatile oil should be divided into two steps, total time was 210 minutes, the total proportions of input of the solvent and raw materials was 81 (mlg), and temprature was 65 degrees C, its extraction rate was 1.83%. The MCMVO was extracted by supercritical CO2, and its extraction rate was 3.4%. GC-MS was used to analyze volatile oil, the results suggested MCMVO contain thymol, carvacrol, P-cycmene, humulene etc. The thymol had the highest content accounts for 56.25%, and the carvacrol was 19.21%. The content of thymol and carvacrol of MCMVO extracted by organic solvent was 58.33% and 22.54%.CONCLUSION:
the content of thymol and carvacrol extracted by organic solvent extraction method is higher than that extracted by supercritical CO2 extraction method. Chemical compositions extracted by organic solvent extraction method are less than extracted by supercritical CO2 extraction method. 10 compositions are firstly extracted by supercritical CO2 extraction method.
