摘要：

Salsolins A (1) and B (2), the new triterpenes, have been isolated from the chloroform soluble fraction of Salsola baryosma a long with 2 alpha,3 beta,23,24-tetra hydroxyurs-12-en-28-oic acid (3) reported for the first time from this species. Their structures have been assigned from H-1 and C-13 NMR spectra, DEPT and by 2D COSY, NOESY, HMQC and HMBC experiments. The compounds 1-3 showed significant antioxidant activity.
