土壤因子对新疆阿魏挥发油成分的初步研究

目的：研究中药新疆阿魏挥发油成分与其土壤因子的关系。方法：在4个不同样地采集阿魏树脂和土壤样品,通过资料查阅和实地调查,考察产地的生态环境。用气相色谱和GC-MS联用方法分析了药材中的化学成分。结果：4个样地挥发油含量均大于10%,符合国家药典规定。挥发油中成分和相对含量也近乎一致。结论：新疆伊宁县白石墩是新疆阿魏的道地产区。其生长地土壤中有机质（17.4-22.6g/kg）、氮（30.3-46.7mg/kg）、磷（5.5-8.5mg/kg）、钾（182.773mg/kg）养分含量较少,pH值（7.91-8.16）偏碱性,总盐含量（1.0-2.6g/kg）相对较高。

Influence of Soil Factors for Chemical Constituens of the Volatile Oil from Ferula Sinkiangensis

Objective： To study the relationship between chemical constituents of the volatile oil from Ferula sinkiangensis and its growing environment of soil factors. Methods： Samples of resin from Ferula sinkiangensis and the soil at its growing site were collected from four selected geographic regions. Reference literatures were reviewed and on- the- spot investigation was conducted to understand the growth environment. Chemical constituents of the volatile oil from Ferula sinkiangensis were analyzed by GC- MS. Results： The contents of the volatile oil from Ferula sinkiangensis in four regions were more than 10%,which met the rule of the national medicine requirement in China. And chemical constituents and relative contents of the volatile oil from Ferula sinkiangensis were almost the same. Conclusion： Baishitun of Yining town in Xinjiang is the main growing site of Ferula sinkiangensis. The contents of organic matters,effective phosphorus,quick-acting potassium are little at the growing site,and the pH value of the soil at the growing site is the alkaline soils. The contents of salt are relatively higher.
