Abstract:Objective: To study the relationship between the chemical components and the planting area of Corni Fructus, Method: Samples collected from 14 localities of three main production areas of Henan, Zhejiang and Shanxi province were obtained. The contents of main chemical components including loganin, ursolic aicd, polysaccharide, tannins, organic acid, water-soluble extraction and alcohol-soluble extraction were determined to analyze the correlation between chemical components and meteorological factors by PASW STATISTICS 18 software. Result: The results showed the content of ursolic acid was negatively correlated with sunshine hours, polysaccharide content was positively with sunshine hours and average annual temperature, water-soluble extraction was positively correlated with average annual temperature. Conclusion: The results provided theoretical support for good quality cultivation of Corni Fructus.
