摘要:

对三七根提取物的表面活性和复配增效性能进行研究。结果表明,三七根提取物在25 ℃的cmc为0.1 g/L,对应的γcmc为43.67 mN/m。在盐度质量分数范围为0%~1%,其表面活性随盐度的增加而增加。在pH范围为4.0~8.0时,三七根提取物的表面张力随pH的降低而降低。根据Rosen理论推算出三七根提取物与聚氧乙烯失水山梨醇月桂酸酯(Tween 20)的最佳复配质量比为4∶1,二元复配体系形成胶束的能力比理论结果增效41.18%。乳化力测试结果显示,三七根提取物与Tween 20复配后的乳化能力和乳化稳定性均与单一使用Tween 20接近,表明三七根提取物与Tween 20的复配具有较好的协同增效能力。而三七根提取物对Tween 60无协同增效作用。

Abstract:

The surface activity and compound synergy of Panax notoginseng root extract were studied. The results show that the cmc of Panax notoginseng root extract at 25 ℃ is 0.1 g/L and γcmc is 43.67 mN/m. In the salinity mass fraction range of 0%-1%, the surface activity increases with the increasing saltness. In the pH between 4.0-8.0, the surface tension of Panax notoginseng root extract decreases with the decreasing pH. According to Rosen’s theory, the optimal compound mass ratio between Panax notoginseng root extract and Tween 20 is 4∶1, and it is found that the ability of the mixed system to form micelles increases by 41.18% compared with the theoretical results. The emulsifying ability results show that the emulsifying ability and emulsifying stability of the mixed system are close to Tween 20 alone, indicating that the combination of Panax notoginseng root extract and Tween 20 has a good synergistic effect, but not on Tween 60.

Key words: natural biosurfactants, saponins, Panax notoginseng root extract, surface activity, synergism
