Ecological Suitability and Quality Regionalization Analysis of Miao Medicine Laportea bulbifera
To explore the potential suitable distribution area and spatial production area of high-quality medicinal materials of Miao medicine
Laportea bulbifera
.
Method
2
Based 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.
Result
2
The 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.
Conclusion
2
L. 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
