ABSTRACT
<p><b>OBJECTIVE</b>To analyze the correlation between environmental factors and the lipophilic and hydrophilic constituents of Polygalae Radix.</p><p><b>METHOD</b>The contents of lipophilic constituent were determined by GC-MS and hydrophilic constituents by HPLC. Geographical factors were collected by on-site inspection and climate factors by the local meteorological data. The relationship between the content of the lipophilic and hydrophilic constituents and the factors were analyzed by SPSS 18.0.</p><p><b>RESULT</b>There was linear relationship between the content of lipophilic constituent and climate factors such as average temperature of July, average temperature of January. There was also linear relationship between hydrophilic constituents and climate factors such as annual average temperature, latitude, annual average rainfall.</p><p><b>CONCLUSION</b>The main climate factors that affect liposoluble constituent content were average temperature of July, average temperature of January, and the main climate factors that affect hydrophilic constituent content were annual average temperature, latitude, annual average rainfall. The study would contribute to the quality evaluation and suitability of origin of Polygalae Radix.</p>
