- 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 °C 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.
