超声波

In the extracting process using ultrasonic wave, the preferable technical parameters of extracting polyphenols from the root and stalk of sanguisorba were acquired by changing the particle size of raw material, the ratio of sample weight to solvent volume, ultrasonic time, ultrasonic power, ultrasonic times.

在超声波法浸提过程中，通过调节料液比、原料粒度、超声时间、超声功率、超声次数因素的影响，确定了地榆根和茎中多酚较佳超声浸提工艺参数。

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。

Coli. The outer membrane protein were extracted from 38 strains of avian E. coli which were isolated from the dead chickens of chicken breeding farms in 3 areas of Baoding, Qiuhuangdao and Beijing by using ultrasonic cleaving and N-Lauroyl Sarcosine Sodium, and OMP typing was done by SDS-PAGE.
