基于主成分分析和聚类分析法的栀子炭质量评价研究
Quality evaluation study of gardenia charcoal based on principal component analysis and cluster analysis
摘要
Abstract
Objective To discuss the quality evaluation standard of gardenia charcoal ( dry gardenia, light degree carbonized gardenia, moderate carbonized gardenia, heavy degree carbonized gardenia) with different processing degree. Methods Four kinds of gardenia charcoal were compared with tannin contents, adsorption force, pH value and conductivity as characteristic variables. Principal component analysis and cluster analysis were used to evaluate the quality of gardenia charcoal. Results The four characteristic variables of different processing gardenia had certain patterns with the deepening of processing degree. The adsorption force varied with the degree of processing. The contents of tannins and conductivity varied as parabola, and the pH value increased. The results of principal component and cluster analysis were coincident, and the dry gardenia and gardenia charcoal with different processing degree were clustered into 4 types. Conclusion Principal component analysis and cluster analysis could be used to evaluate the quality of gardenia charcoal, which is reliable and could provide reference for evaluating the quality of fructus gardenia.关键词
