Hypothesis
The study aims to evaluate the antioxidant activities and phenolic contents of the methanol extracts of Acokanthera oppositifolia and Adenia gummifera.
Conclusion
The extracts of Acokanthera oppositifolia and Adenia gummifera possess antioxidant properties and could serve as free radical inhibitors.
Supporting Evidence
- The antioxidant activities of Acokanthera oppositifolia were higher than that of Adenia gummifera.
- The levels of total phenols and flavonols for A. oppositifolia were also higher.
- Adenia gummifera had higher levels of total flavonoids and proanthocyanidins than A. oppositifolia.
- The ABTS activities of both plant extracts were similar and comparable to that of BHT.
Takeaway
This study found that two plants can help protect our bodies from harmful substances called free radicals.
Methodology
The antioxidant activities and phenolic contents were evaluated using in vitro standard procedures including spectrophotometry.
