摘要/Abstract

摘要： 对全年各月虎杖材料中白藜芦醇含量,及其Ca、Cu、Fe、K、Mg、Na、Zn 8种矿质元素积累进行检测,结合气象因子动态变化,采用主成分分析法,研究了不同季节虎杖白藜芦醇含量动态变化与其矿质元素、气象因子动态变化的关系.结果表明,Cu与Fe,Mg与K、Zn,Ca与月日照时数,K与Zn相关系数分别为0.812、0.871、0.793、0.602、0.729,呈极显著正相关;Cu、Mn与月平均气温,Fe与K相关系数分别为-0.738、-0.712、-0.766,呈极显著负相关;Cu与白藜芦醇含量呈显著负相关.找出了影响虎杖白藜芦醇含量动态变化的个主成分,其中"酶促反应促进性矿质营养因子","高温、强照射气象因子"的贡献率分别为35.539%、33.358%,合计为68.897%,二者对不同季节虎杖白藜芦醇的变异贡献率最大.同时进行白藜芦醇含量的动态变化与主成分的多元相关、回归分析,建立了回归方程.

Abstract: By determining monthly the content of resveratrol and eight mineral elements (Ca,Cu,Fe,K,Mg,Na,Zn,Mn) in the rootstalk of Polygonum cuspidatum,by considering the dynamic meteorological factors and by analyzing the principal components,we are investigating the dynamic relationship laws among mineral elements,meteorological factors and the content of resveratrol in Polygonum cuspidatum rootstalk in varied seasons.The results indicated that the correlation coefficient between Cu and Fe;between Mg and K;between Mg and Zn;between K and Zn;between Ca and average sunlight hours per month are 0.812,0.871,0.793,0.729,0.602.Their correlation is markedly in the positive 0.01 levels.The correlation coefficient between Cu and average air temperature in a month;between Mn and average air temperature in a month;between Fe and K are -0.738,-0.712, -0 766.Their correlation is markedly in negative 0.01 levels.The correlation between Cu and the content of resveratrol is markedly in negative 0.05 levels.Of the five principal factors affecting the content of resveratrol,two were found to be principal:“mineral element factors of promoting enzyme reacts" and “the meteorological factors of high temperature and strong shines".The percentage results of these two principal are 33 539% and 33.358%,making a total of 68.897%.The two factors above are also the main reasons for the variation of Polygonum cuspidatum resveratrol.A regression equation was set up through correlation and regression analysis between the changing content of resveratrol and the principal component.
