茶皂素的提取及其溶液的表面性质
Extraction of tea saponin and surface performance of its solutions
摘要
Abstract
The tea saponin was extracted from camellia cake by ethanol, and the influences of pH and electrolyte (NaCl) concentration on the surface performance of tea saponin solutions were investigated. It was shown that the critical micelle concentration (cmc) increased, while the surface dilational modulus decreased with increasing pH value of solution. NaCl has little effect on the surface tension and cmc, but it decreased the surface dilational modulus of tea saponin solution due to breaking the hydrogen bond between surfactant molecules on surface. The surface dilational modulus of tea saponin is more than 200 mN/m under neutral condition, which may be the main reason for it high foam stability.关键词
