Ternstroemia pringlei is a medicinal plant widely distributed in Mexico. Since, a series of antioxidative phenylethanoid glycosides have been isolated in the Asiatic species T. japonica [1], we decided to study the antioxidative action of T. pringlei extracts obtained from various organs, and to investigate the presence of phenyethnanoid glycosides. Two new compounds (TP1 and TP2) were isolated from calyx with fruit and flowers. The in vivo inhibition of intracellular oxidation was estimated using the Saccharomyces cerevisiae model [2], and indicated that extracts from seeds, flowers and leafs; as well as the isolated compounds TP1 and TP2 exhibited higher antioxidative action when compared to Vitamin C at 100µg/ml and 100µM respectively.
