摘要

目的: 考察了贵州都匀产铁包金不同部位总黄酮含量的差异。方法: 以乙醇作为回流提取溶剂提取铁包金中总黄酮。以芦丁为对照品

采用紫外分光光度法测定铁包金中的总黄酮。结果: 芦丁标准品溶液浓度在5~30 μg·L-1与吸光度有良好线性关系

回归方程为Y=0.011 2X+0.041 9(r=0.999 1)

平均加样回收率98.56%

精密度试验RSD值为0.279%

重复性试验RSD为0.634%

稳定性试验RSD 1.49%。以此方法测定

铁包金叶和茎部中黄酮含量分别为12.3%

1.42%

叶中总黄酮含量是茎部的的8.7倍。结论: 贵州都匀产铁包金叶和茎部中黄酮含量存在较大差异

叶部位具有较大的药用开发价值和应用前景。

Abstract

Objective: The content distribution of total flavonoids in different parts of Berchemia lineate from city of DuYun in Guizhou was investigated. Method :Flavonids in different parts of Berchemia Lineate(L)DC. were extracted by ethanol as solvent reflux

The total flavonoids were determined by spectrophotometry

rutin as control sample. Result: The absorbency and concentration of rutin have good linear correlation in the range of 5-30 μg·L-1.The regression equation was Y=0.011 2X+0.041 9(r=0.999 1)

the average recovery rate was 98.56%

Accuracy experiment RSD 0.279%

repeatability test RSD 0.634%

stability test RSD 1.49%

the contents of total flavonoids in leaf and stem was respectively 12.30% and 1.42%

that the means content of total flavonoids in leaf is 8.7 times higher than that in stem. Conclusion: the content of total flavonoids in the leaf and in the stem has a big difference

thereby the leaf of B. lineate from Duyun in Guizhou has value to be developed and used.
