目的:通过对厚朴中的厚朴酚、和厚朴酚含量及其比值与产地生态因子之间的相关性考察,进行全国厚朴质量适宜性等级划分,为确定厚朴的优质药材种植区提供科学依据。方法:对全国43个样点的厚朴药材进行质量分析,利用统计方法分析厚朴的酚含量及其比值与影响因子之间的关系;应用地理信息系统进行全国厚朴质量适宜性等级划分。结果:十月降水量、海拔、十一月降水量等12个生态因子是影响厚朴质量的主要生态因子;厚朴酚与和厚朴酚比值具有明显的区域质量特征。结论:湖北和重庆是厚朴的道地产区。
OBJECTIVE: To investigate the correlation between magnolol and honokiol content in Magnolia officinalis and the ecological factors in the origin of Magnolia officinalis, and to evaluate the quality suitability of Magnolia officinalis in China. Provide a scientific basis. Methods: The quality of Magnolia officinalis collected from 43 sample sites in China was analyzed. The relationship between the phenol content of Magnolia officinalis and its ratio and its influencing factors was analyzed by using statistical methods. The grade of Magnolia quality was appraised by using geographic information system. Results: 12 ecological factors, such as precipitation in October, elevation and precipitation in November, were the main ecological factors affecting the quality of Magnolia officinalis. Magnolol and honokiol ratio had obvious regional quality characteristics. Conclusions: Hubei and Chongqing are the Magnolia real estate areas.
