Was studied by Folin Ciocalteu colorimetry. The results showed that polyphenol content of C. album could be well calculated according to their colorime tric absorption at 765nm by applying Folin Ciocalteu reagent 1.5mL and 10% Na2CO3 6 mL,2 h at 30℃ for colorimetric reaction, and the linear range of standard curve was 7-70mg/L.The method established was very convenient, stable and accurate.Key words: Canarium album Rauesch.;polyphenol;colorimetry
结果表明:橄榄多酚提取液在加入Folin Ciocalteu试剂1.5 mL,10% Na2CO3 6 mL,反应时间2 h,温度30℃的条件下进行显色,并于765 nm处测定其吸光值,多酚质量浓度在7~70mg/L范围内与吸光值有良好的线性关系,根据此线性回归方程进行橄榄多酚的定量测定,该方法简单方便,稳定性好,准确度高。

Based on the analysis and comparison of various methods of mensuration of effective ingredients of indigowoad root,phenol-vitriolic colorimetry has been choosen to be the method of mensuration of amylose in indigowoad root, and standard amylose graph has been made,in which c=22.476A+0.5309, correlation rate r=0.9970; Direct colorimetry has been choosen to be the method of mensuration of indigotin and Indirubin,and based on all above,the maximal absorb wavelenghes of indigotin and Indirubin have been determined through experiment.
在分析比较各种板蓝根有效成分测定方法的基础上,选用苯酚-硫酸比色法作为板蓝根多糖的定量测定方法,作山了多糖的标准曲线:c=22.476A+0.5309,其相关系数r=0.9970;选择直接比色测定法作为靛蓝、靛玉红的测定方法,并在此基础上通过试验确定了靛蓝、靛玉红的最大吸收波长及显色稳定性。
