枳壳有效成分含量与土壤因子的相关性分析

Correlation between Content of Active Ingredients of Aurantii Fructus and Soil Factor

目的:研究不同主产区枳壳有效成分含量与土壤因子的相关性,为实施土壤生态调控,提高枳壳药材品质及揭示枳壳道地药材成因提供理论依据。方法:测定不同产地共计25批次枳壳样品中的柚皮苷、新橙皮苷、总黄酮、挥发油的含量及土壤全氮、全磷、全钾等17种土壤因子相关指标。通过Pearson相关分析法、主成分分析法和灰色关联度分析法综合分析,解析影响枳壳有效成分含量变异的主导土壤因子。结果:土壤的pH介于4.83~8.21,整体呈弱酸性和中性的特征;土壤肥力中等偏上水平。Pearson相关性分析表明与枳壳4种有效成分最相关的土壤因子是全磷、有效态铜、有效态锌、交换性镁、有效态硫、有效磷、有效钼。主成分分析表明全氮、碱解氮、有机质、有效磷、有效态锌为土壤中的主要特征因子。灰色关联度分析表明影响枳壳有效成分的主导土壤因子是全磷、全氮、有效态铜、有效态锌、交换性镁、pH。结论:在枳壳的种植栽培中可以通过调节土壤中有益因子的水平,适当改良土壤质地等措施,提升枳壳药材品质。

Objective:To study the correlation between the content of active ingredients of Auranti Fructus in different main production areas and soil factors,so as to provide a theoretical basis for implementing ecological regulation of soil,improving the quality of Auranti Fructus,and revealing the origin of genuine medicinal materials.Method:The content of naringin,neohesperidin,total flavonoids,volatile oil,total nitrogen,total phosphorus,total potassium,and 17 soil factor-related indicators in 25 batches of Auranti Fructus from different production areas were determined.The main soil factors affecting the content of active ingredients of Aurantii Fructus were analyzed by Pearson correlation analysis,principal component analysis,and grey correlation analysis.Result:The pH value of the soil is between 4.83 and 8.21,and the soil is weakly acidic and neutral in general.Soil fertility exceeds the average.Pearson correlation analysis shows that the soil factors most related to the four active ingredients of Auranti Fructus are total phosphorus,available copper,available zinc,exchangeable magnesium,available sulfur,available phosphorus,and available molybdenum.Principal component analysis shows that total nitrogen,alkali-hydrolyzable nitrogen,organic matter,available phosphorus,and available zinc are the main characteristic factors in soil.Grey correlation analysis shows that the main soil factors affecting the active ingredients of Aurantii Fructus are total phosphorus,total nitrogen,available zinc,available copper,exchangeable magnesium,and pH.Conclusion:In the cultivation of Auranti Fructus,the medicinal material quality of Auranti Fructus could be improved by adjusting the level of beneficial factors in the soil and improving the soil texture.
