ABSTRACT
Objective:To study on the quality regionalization of <italic>Angelica sinensis</italic>，in order to guide the rational cultivation of <italic>A. sinensis</italic>. Method:Through visits and field surveys，a total of 857 batches of <italic>A. sinensis</italic> were collected from different counties of Dingxi，relevant geographic information such as longitude，latitude，altitude of each sampling point were obtained by using the global positioning system（GPS），the content of 8 indexes in <italic>A. sinensis </italic>was detected by UPLC， and based on national ecological environment factor data，the suitability analysis of the quality of <italic>A. sinensis</italic> was performed by using MaxEnt，ArcGIS，SPSS. Result:The suitable areas of <italic>A. sinens </italic>were concentrated in central and southern Dingxi. In the suitable areas，the content of ferulic acid，coniferyl ferulate，senkyunolide H decreased from south to north，the content of chlorogenic acid decreased from north to south，the content of senkyunolide A，senkyunolide I decreased from east to west，the distribution regularity of butenyl phthalide was not strong，the highest-content areas were in western Min county，Qingyuan town of Qingyuan county，Shangwan Township and Huichuan town. The content of ligustilide was consistent in the suitable area，and the highest content were in the middle of Weiyuan county and the northern Tongwei county. The results showed that it had a higher index components and comprehensive quality in Min county，Zhang county，southern Weiyuan county and northern Tongwei county. Conclusion:In this study，the quality suitability areas of <italic>A. sinensis</italic> in Dingxi were graded. The chemical components and the quality suitability zoning maps were generated. The findings could provide references for the comprehensive utilization of <italic>A. sinensis</italic>，the selection and construction of high-quality <italic>A. sinensis</italic> raw material base，and the scientific guidance for the production and regional development of <italic>A. sinensis</italic> in Dingxi.
ABSTRACT
Objective: To study the ecological suitability of Angelica sinensis growing in Gansu Province and guide the rational cultivation. Methods: Through visiting and field investigation, 1 545 batches of Chinese angelica samples were collected from the county areas in Gansu Province. The information about the longitude, latitude, altitude of each sampling point was collected by using the GPS, combining with national environmental factor data, and using Maxent model and spatial analysis function of ArcGIS software. Results: The areas with high suitability of A. sinensis distribution are in the southeast of Gansu Province. The main ecological factors affecting the suitability distribution of A. sinensis were altitude, rainfall in March, May and December, wettest month precipitation, soil pH and other ecological factors. Conclusion: The research findings are basically consistent with the living habits of A. sinensis that cultivated in high-cold mountain areas and plateau flat pasture areas with a cool climate, moderate soil, moisture, slightly acidic to neutral fertile and loose brown sandy loam soil. This result can provide scientific basis for the reasonable distribution of A. sinensis cultivation area in Gansu Province.
