Abstract
Objective To optimize the extraction process of patchouli volatile oil,to establish a simultaneous determination method of the patchoulenone and patchouli alcohol contents,and to compare the qualities of the Pogostemon cablin from different habitats. Methods The optimal extraction technology of patchouli volatile oil was determined with the orthogonal experiment;the gas chromatography method was adopted to simultaneously determining the content of patchoulenone and patchouli alcohol. The qualities of the patchouli medicinal material from different habitats were evaluated by the total content of patchoulenone and patchouli alcohol,as well as the yield of volatile oil. Results The optimal extraction of patchouli volatile oil was adding 8 times the amount of water,soaking for 4 h,then con-ducting distillation extraction for 4 h;the established content determination method had good linearity and high accuracy,and was stable and reliable. Conclusion The optimized extraction technology is scientific and reasonable and suitable for the industrialized production of patchouli volatile oil;the established the content determination method of patchoulenone and patchouli alcohol is accurate,reliable and easy to operate with good reproducibility,which is suitable for the quality control of Pogostemon cablin;Pogostemon cablin from 5 dif-ferent habitats has great differences in the aspects of yield of volatile oil and the total contents of patchoulenone and patchouli alcohol.关键词
