ABSTRACT
Totally 21 batches of Gastrodiae Rhizoma pieces from various habitats with different appearance characteristics were analyzed. Five active components( gastrodin,4-hydroxybenzyl alcohol,parishin B,parishin C,and parishin A) were determined by UPLC. Polysaccharide content was determined by phenol sulfuric acid method. And the content of alcohol extracts was determined. The correlation between appearance characteristics and active components,polysaccharide content and amount of alcohol extracts of Gastrodiae Rhizoma pieces was statistically analyzed by SPSS 19. 0 software. And the five active components in the 21 Gastrodiae Rhizoma pieces were clustered by using the Ward' s method in SPSS 19. 0 software. The study found that inconspicuous keratinous Gastrodiae Rhizoma had a low content of each component,and the degree of keratin was positively correlated with the content of each component and the extract,with no significant correlation with the polysaccharide content. In the cluster analysis,the 21 batches were divided into three groups,except the second group whose gastrodin content was significantly higher than the special conditions of other groups. According to the content of the five active components,19 batches of Gastrodiae Rhizoma pieces were classified into two groups with obvious keratin and no obvious keratin. In terms of color,with the deepening of brown color,the content of each component showed a downward trend. The grading of decoction pieces of Gastrodiae Rhizoma shall give full consideration to the color and texture. And the combination of chemical composition and appearance characteristics is an indicator to evaluate the product specification standards.
