Abstract:
Objective To analyze the correlation between the number of oil chambers,the proportion of phloem at cross-section of Aucklandiae Radix and the contents of costunolide and dehydrocostuslactone,and the correlation between inulin quantity,vessel quantity and polysaccharide content in powder characteristics,so as to explore the scientific basis for Aucklandiae Radix"identifying the quality based on appearance differentiation".Methods The constant values of the microscopic features of oil chambers,inulin and vessels were determined by cross-sectional permanent slice method,chloral hydrate method and counting analysis method,and the contents of costunolide and dehydrocostuslactone as well as polysaccharide content were determined by the high-performance liquid chromatography(HPLC)and the phenol-sulfuric acid method,respectively,and the correlation in the two groups of data was analyzed by statistical methods.Results There was a significantly positive correlation between the number of oil chambers per unit area in the cross-section of Aucklandiae Radix and the number of oil chambers per unit area in the phloem and the contents of costunolide and dehydrocostuslactone;there was a significantly positive correlation between the quantity of inulin in the powder of Aucklandiae Radix and the polysaccharide content;there was no correlation between the quantity of vessels and the polysaccharide content.Conclusion This study initially established a new method and a new technology for quality evaluation of Chinese herbal medicines based on the determination of microscopic characteristic constants of Aucklandiae Radix,which can provide a new technical method for the quality control of Aucklandiae Radix.
