Abstract:
ObjectiveTo explore the potential suitable distribution area and spatial production area of high-quality medicinal materials of Miao medicine Laportea bulbifera. MethodBased on 200 distribution spots of L. bulbifera and 120 ecological factors, the maximum entropy model（MaxEnt） and ArcGIS software were applied to predict the potential suitable areas. The content of rutin, kaempferol-3-O-rutinoside, and quercitrin from 33 batches of L. bulbifera in Guizhou province was determined by high-performance liquid chromatography (HPLC). Combined with the previous content data of total polysaccharides and total flavonoids, the correlation between the main pharmacodynamic components of L. bulbifera and ecological factors was analyzed. Eventually, the quality regionalization of L. bulbifera was exhibited by the collocated Cokriging in ArcGIS. ResultThe optimum distribution areas of L. bulbifera were Yunnan, Guizhou, Sichuan, Hunan, and Hubei provinces in China, and the high and medium suitable areas accounted for 59.48% of the total distribution areas. October precipitation, slope, min temperature of the coldest month, altitude, solar radiation intensity in June, and April precipitation were the main ecological factors affecting the growth and distribution of L. bulbifera. Temperature, radiation intensity, precipitation, and soil composition and properties had great effects on the accumulation of secondary metabolites in L. bulbifera. The results showed that the high-quality areas of L. bulbifera mainly included Leishan county, Kaili city, Qingzhen city, Pingba district, Huishui county, Longli county, Kaiyang county, and Jiangkou county in Guizhou province. ConclusionL. bulbifera is widely distributed in China， but the suitable distribution areas are mainly concentrated in southwest China and part of central China. The planting bases of L. bulbifera can be selected in parts of cities and counties in southeast and central Guizhou province. In this study， the potential suitable growing areas and the optimum planting areas of L. bulbifera in Guizhou were predicted， which could provide scientific references for the cultivation and the site selection of large-scale planting for L. bulbifera.
