Paper Abstract

The biological activity of teasaponins and their molecular structure are closely related, and the activity of saponins may be increased with the change of their molecular structure. In this report, teasaponins were hydrolyzed by Aspergillus niger for increasing the antioxidant activity. The antioxidant activity of teasaponins before and after hydrolyzed was tested by DPPH, and the result showed four new teasaponins were produced after hydrolysis, and their antioxidant activity was increased significantly than the original teasaponins before hydrolysis, the radical scavenging capacity (RSC) was partly up to 95 %.
