新疆民族药多伞阿魏挥发油成分与土壤因子相关性研究

Correlation Analysis between Volatile Oil of Ferula ferulaeoides of Xinjiang Ethnic Medicine and Soil Factors

目的研究土壤因子对多伞阿魏挥发油成分的影响,筛选影响其含量的主导因子。方法测定不同产地多伞阿魏挥发油成分含量及相应生长地土壤养分和pH值等,采用单因素方差分析、相关分析和偏最小二乘法和灰色关联等统计方法分析土壤因子对多伞阿魏挥发油成分含量的影响。结果不同产地多伞阿魏挥发油成分含量和土壤因子均有显著差异。多伞阿魏12种挥发油成分总含量与土壤pH值呈显著负相关(P<0.05);愈创木醇与速效钾呈显著负相关(P<0.05);α-蒎烯与土壤速效氮、速效钾呈显著正相关(P<0.01);莰烯、右旋柠檬烯与土壤速效钾呈显著正相关(P<0.05);异愈创木醇与全磷呈显著正相关(P<0.05);β-金合欢烯与速效磷呈显著负相关(P<0.05)。偏最小二乘法分析表明,土壤pH值、速效钾含量对多伞阿魏挥发油成分的积累具有重要意义。灰色关联分析表明,土壤pH值、含水量和速效钾与多伞阿魏挥发油成分关联度较大。结论不同产地多伞阿魏挥发油成分含量和土壤因子均有显著差异。各土壤因子对多伞阿魏挥发油成分的影响各有不同,土壤pH值、含水量和速效钾的含量可能是影响多伞阿魏挥发油成分含量的主导因子。

OBJECTIVE To explore and screen the soil factors which influences the volatile ingredient of Ferula ferulaeoides. METHODS By measuring the content of volatile ingredient of Ferula ferulaeoides, soil nutrients and pH value in the corresponding place, using the One-way ANOVA, correlation analysis, partial least squares（PLS） methods and grey relational analysis（GRA） to analyze the soil factors which have great effect on the volatile ingredient content from Ferula ferulaeoides. RESULTS The content of volatile constituents of Ferulaferulaeoides and the soil factors from different habitats were significantly different. The total content of 12 volatile components of Ferula ferulaeoides and soil pH value were significantly negative correlated with each other（P〈0.05）; the content of guaiol were negatively associated with the available K（P〈0.05）; the a-pinene showed a significant positive correlation with the available N, K（P〈0.01）; the content of camphene and d-limonene showed significant positive correlations with the available K（P〈0.05）; bulnesol were positively correlated with total phosphorus（P〈0.05）, fl-famesene showed a significant negative correlation with available phosphorus（P〈0.05）. By the analysis of PLS, the soil pH value and the content of available K were important to the volatile components of the Ferula ferulaeoides. GRA showed that the pH value, water content and available K in the soil were large correlation to the volatile oil of the Ferula ferulaeoides. CONCLUSION The contents of volatile constituents and soil factors of different habitats were significantly different. The soil pH value, the content of available K, and natural water content are the main factors that influence the content of volatile components of Ferulaferulaeoides.
