Free radical scavenging capacities of Cortex Magnoliae Officinals as affected by different extraction methods

摘要

The superoxide anion radical and hydroxyl radical scavenging capacities of Cortex Magnoliae Officinals extracts were researched, and the effect of different extracting methods (reflux, ultrasonic and microwave extraction) on the scavenging capacities were studied too. The results indicated that Cortex Magnoliae Officinals extracts had obvious radical-scavenging capacities, and the scavenging capacities were different by different extraction methods. In three kinds of extraction methods, the hydraxyl radical scavenging capacity of Cortex Magnoliae Officinals extract with reflux extraction method was strongest and the superoxide anion radical scavenging capacity of Cortex Magnoliae Officinals extract with ultrasonic extraction method was strongest.
