After elution with 95% ethanol and 50% acetone, two phenolic fractions were obtained from the crude extract of of <em>S. apetala</em> pneumatophore. The acetone fraction consisted of tannins having high antioxidant activity, 1.14 times higher than that of ascorbic acid. This fraction also have higher activity of α-amylase inhibition (IC<sub>50</sub> 0.83 mg/mL) and <em>R. sativus </em>root growth inhibition (IC<sub>50</sub> 6.4 mg/mL) than did the ethanol fraction. In contrast, ethanol fraction consisted of low-molecular phenolic compounds having inhibitory effects on <em>Samonella tiphimurium </em>growth. Such antibacterial activity was not observed in the acetone extract.</p><p> </p><p><em>Citation: </em>Nguyen Sao Mai, Dao Van Tan, 2017.
