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 influences of environmental factors on the abiotic methylation were studied. The biggest production of methylmercury was found after 2 days of incubation in presence of FA. The rate of production of methylmercury depends upon temperature. In presence of FA from sediment, the biggest production of methylmercury was found under 40℃. In presence of FA from soil, production rate increases with temperature. The biggest production of methylmercury was found when solution pH was 2 and 4 in presence of FA from sediment and soil, respectively. Increase in concentrations of inorganic mercury and FA solution causes an increase in the production of methylmercury. Under irradiation with ultraviolet ray, blacklight lamp as well as natural light, methylation is stimulated, especial for irradiation of ultraviolet light.

环境条件对汞甲基化作用的影响研究得出，在底泥和土壤FA体系中甲基汞产量均在反应2天后达到最大值；在底泥FA体系中汞的甲基化在反应温度为40℃时产量最大，而在土壤FA体系中，甲基汞产量在10～60℃之间随反应温度升高而增加；底泥和土壤FA体系中汞的甲基化分别在pH值为2和4时最大；甲基汞产量均随无机汞浓度和腐殖质浓度的增加而增加；紫外线、黑光灯和自然光照射都可促进甲基汞的生成，紫外线的作用尤其明显。
