摘要
以溴酚蓝作为测试用酸性染料,在总生物碱与其生成稳等络合物时间范围内,利用色法测定了榅桲中总生物碱的含量,首次测得榅桲中生物碱的含量1.4%左右。并认为此法快速简便,准确度好。
The total alkaloid content in the cydonia. Mill was assayed by using spectrophotometer by way of bromophenol blue for testing acid dyes. When the total alkaloid formed stable complex compound with bromophenol blue. The alkaloid content in the cydonia oblonga Mill was first time assayed as about 1.4%. This method could be considered as quick, simple method with higha ccuracy.
