| 摘 要： | 茶树芽叶中的花色苷含量测定尚无国家标准,目前仍沿用单一pH法进行测定.比较了单一pH法和pH示差法对花色苷含量测定的结果.单一pH法所测花色苷含量高于pH示差法,两者存在良好的线性关系(R2=0.992 7).pH示差法能较好地消除干扰物质对测定结果的影响,为茶叶的花色苷定量分析提供了依据.

| Abstract: | There is no national standard yet for measuring anthocyanins of purple tea leaves.The methods for determining Anthocyanins of tea leaves by single-pH and pH-Differential spectrophotometry were compared in this paper.The results indicated that anthocyanins content measured by single-pH was much more than that measured by pH-Differential spectrophotometry.The two methods had good linear relation(R2=0.9927).The effects of interfering substances on quantitative analysis of anthocyanins could be eliminated by us... |
