It was investigated how to increase the yield and purity of tannin, flavone and oligoprocyanidms from the root and stalk of sanguisorba, and the stability of polyphenols from sanguisorba was studied, too. The chemical constitutes of sanguisorba were analyzed, the conditions on extracting tannin, flavone and oligoprocyanidins from sanguisorba by general lixiviating process and ultrasonic wave were optimize. The flavone and oligoprocyanidins were separated from sanguisorba and purified. The stability of polyphenol from sanguisorba was studied and the chemical structure of the products was analyzed.

本论文以地榆根茎为原料，对如何提高其主要活性成分鞣质、黄酮类物质以及低聚原花青素得率和纯度以及地榆多酚的稳定性进行了探讨；主要分析了地榆中化学成分，常规浸提和超声波浸提对地榆根茎中鞣质、黄酮类以及低聚原花青素提取条件的优化，地榆根中黄酮类和低聚原花青素的分离纯化，地榆多酚稳定性能以及产品的初步化学结构分析。

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.

研究了pH值、光、热、紫外线、氧化剂、还原剂以及添加剂对地榆提取物稳定性的影响，结果表明地榆提取物适合弱酸或中性条件下使用，使用范围比较广；但对光热稳定性较差，适合在避光低温的环境；具有很强的抗紫外线能力；氧化剂对地榆提取物稳定性影响较大，会加速其降解，还原剂对地榆提取物影响不大；其他添加剂对其稳定性几乎没有影响；并通过UV和FTIR光谱分析，超声波浸提没有对地榆根茎中有效成分的结构发生改变。

The result indicates that the best method for extracting β-carotene is to saponify the test specimen one hour with 4% NaOH methyl alcohol solution in 60-70'c and then to separate with 3:7 acetone-benzine component solvent as extraction solvent, MgO as the absorbent, the acetone-benzine as the eluent. Extracted solvent has been determined in the color dish condition (1cm) by ultraviolet spectrophotometer at 447 nm. The result shows that the β-carotene in carrotis 0.134 mgg^(-1), 0.0863mgg^(-1) in red pepper and 0.0426 mgg^(-1) in spinach.
