Other claims from this paper (4)
- Intervention effect The 95% ethanol extract of roselle had the lowest radical-scavenging activity.
- Association Higher antioxidant activity of the 30% ethanol extract is associated with its higher total phenol content, 20.25 mg GAE/g.
- Association Correlation coefficients R2 between antioxidant activity and phenol, anthocyanin and saccharide contents were 0.9615, 0.9089 and 0.9771.
- Recommendation The authors recommend the 30% ethanol extract of roselle as a good natural antioxidant.
