Hypothesis
The study aims to evaluate the DPPH radical and superoxide anion scavenging properties of Rhizophora mangle extract and its polyphenol fraction.
Conclusion
Rhizophora mangle aqueous extract showed potent antioxidant activity against DPPH radicals and superoxide anions.
Supporting Evidence
- The extract showed better activity than its fraction in DPPH radical scavenging.
- The polyphenolic fraction exhibited better superoxide anion scavenging ability than the extract.
- Antioxidant activities increased with higher tannin concentrations.
Takeaway
This study found that a plant called Rhizophora mangle can help fight bad things in our body called free radicals, which can make us sick.
Methodology
The antioxidant activities were investigated using DPPH and superoxide anion radical scavenging assays.
