中药材祖师麻化学成分与生态因子和土壤因子的相关性研究

研究中药材祖师麻化学成分与生态因子和土壤因子的相关性,为祖师麻人工栽培适宜区的选择及野生抚育提供参考依据。该研究运用地理信息系统(GIS)获取祖师麻23个采集地的生态因子信息,以土壤测试标准手册中的标准程序测定土壤因子信息,结合23个采集地93份祖师麻化学成分含量信息,运用统计学方法进行成分与生态因子和土壤因子的相关性分析。相关性分析结果显示:经度、年均降雨量、年均日照强度和年均温等生态因子以及土壤类型、有效铜、pH等土壤因子都是影响祖师麻化学成分的主导因素。

Correlation between chemical composition,ecological factors and soil factors of Chinese herbal medicine Daphnes Cortex

In this paper, the correlation between the chemical constituents of Chinese herbal medicines Daphnes Cortex and the ecological factors and soil factors was studied, which provided a reference for the selection of suitable areas for artificial cultivation of Daphne giraldii and wild tending. The geographic information system(GIS) was applied to obtain the ecological factor information of 23 collection sites of Daphnes Cortex, and the soil factor information was determined by the standard procedure in the soil test standard manual. Combining the information of 93 chemical constituents of Daphnes Cortex in 23 collection sites the correlation between components and ecological factors and soil factors was analyzed by statistical methods. The correlation analysis showed that the longitude, annual average rainfall, annual sunshine intensity, annual average temperature in the ecological factors, soil type, effective copper and pH value were the dominant factors affecting the chemical composition of Daphnes Cortex.
