黄芪土壤的红外指纹图谱特征及其比较研究

利用简便、快速、分辨率高，信息丰富的FTIR，对道地黄芪产地：山西省浑源县官儿乡的6个产地;应县白马石乡的3个产地;繁峙县周庄;内蒙古固阳县的2个产地及其这些产地各4个生长年限生长黄芪的土壤样品(共计42个)，进行了较详细的研究，得到了一些有益的结论：黄芪土壤FTIR特征不同于一般土壤;不同产地黄芪土壤的FTIR特征有别，黄芪品质各异;黄芪土壤FTIR特征与党参土壤大不相同;FTIR指纹图谱可以为中药种植的地域选择提供重要信息。

The FTIR Spectral Characteristics and Comparison Study of Astragalus Menbranceus Soil

To study the genuine soil of Astragalus menbranceus grows, FTIR spectrometry was used, which is accurate, simple and efficient and has high resolution. The genuine soils include six areas in Hunyuan of Shanxi province, three areas in Yingxian of Shanxi province, Fansi of Shanxi province, and Guyang of Inner Mongolia. Different growth years of two to five for each area were also studied. The results show that there are significant differences between Astragalus menbranceus soil FTIR spectrometry and general soil’s, between soil of Astragalus menbranceus growth and radix codonopsitis growth, between different soil of Astragalus menbranceus growth, providing useful information for the area chose of Chinese herb cultural and transplantation.
