Abstract: In order to study thymol amassment characteristic of Moslem chinensis Maxim in different vegetation periods,supercritical CO2 extraction technology was used to extract main components of Moslem chinensis Maxim,and high-performance liquid chromatography(HPLC) was used to analyze thymol content in Moslem chinensis Maxim extract. The results showed that there is positive relationship between thymol amassment characteristic and growth period of Moslem chinensis Maxim. The thymol amassment characteristic can be divided into three periods of slow amassment period,rapid amassment period and stable period. The change trends of thymol proportion in Moslem chinensis Maxim extract can be presented as ascent stage,downward stage and stable stage.

Key words: Moslem chinensis Maxim, supercritical CO2 extraction, thymol, amassment characteristic
