紫芽茶树不同季节主要生化成分变化分析
The Analysis of Main Biochemical Components of Purple Shoots of Tea Plant in Different Seasons
摘要
Abstract
One bud with two leaves of C18-1 was selected as the experimental material.A single-factor analysis was adopted to optimize the extraction method of anthocyanin in tea plants.The differences of main biochemical components in different seasons of C18-1 were studied.The results showed that the factors such as solvent type,solvent concentration,extraction time and temperature had significant effects on anthocyanin extraction.In this experiment,the optimum extraction method of anthocyanin is:ethanol solution with 3％ hydrochloric acid,reflux extraction 1 hour under 80 ℃.The contents of water extracts,caffeine,tea polyphenols,anthocyanin and free amino acids showed different changes with different seasons,and the seasonal differences were significant.The contents of water extracts,caffeine and free amino acids were the highest in spring,and the contents of tea polyphenols and anthocyanin in summer were the highest.关键词
