摘要
目的:分析土壤、气候条件等环境因子对远志药材品质的影响。方法:用高效液相色谱法测定远志酸含量,通过实地调查与查阅当地气象资料研究远志生长地的海拔、年平均温度、7月平均温度、年降水量、年日照时数以及无霜期与远志酸含量的关系;采用常规方法测定土壤水分含量、pH值以及土壤营养元素含量,并考察与远志酸含量的关系。结果:远志酸含量与7月平均温度、年降水量、年日照时数以及无霜期等气候因子存在线性关系;与土壤全氮、全磷、有效磷、速效钾、有机质含量以及水分含量等土壤因子存在线性关系。结论:影响远志酸含量的地理气候因子主要是年日照时数和无霜期,土壤因子主要是有效磷与土壤水分含量。
OBJECTIVE： To analyze the effects of environmental factors （soil, climate, etc.） on the quality of Radix Polygalae. METHODS： The contents of polygalic acid were determined by HPLC. Climate factors including altitude, average annual temperature, average temperature of July, annual precipitation, annual sunshine hours and non- frost days were collected through on- site inspection or from the local meteorological data. Water content, pH and nutritional elements of the soils were determined by routine method, and the reletionship between the content of polygalic acid and the factors were analyzed.RESULTS： There was linear relationship between the content of polygalic acid and climate factors such as average temperature of July, annual precipitation, annual sunshine hours and non- frost days. There was also linear relationship between polygalie acid and soil factors such as total nitrogen, total phosphor, available phosphor, available kalium, organic matters and water content. CONCLUSION： The main climate factors that affect polygalic acid content were annual sunshine hours and non-frost days, while the main soil factors affecting the content of polygalic acid were the content of available phosphor and soil water content.
