llustrates that the solvent extracts from the stems of M. paniculata showed a concentration-dependent DPPH radical scavenging activity. The DPPH radical scavenging effect of the solvent extracts at 500 μg/mL decreased as follows: EtOAc > n-BuOH > water > petroleum ether (P.E.), and were 94.19%, 90.50%, 82.85% and 33.48%, respectively
