Analysis reveals moderate antioxidant activity and phenolic content in anthospermum emirnense roots from Madagascar, suggesting potential in phytomedicine.
Key Points
The total phenolic content was determined to be 168 mg gallic acid equivalents per gram of the crude ethanol extract, indicating the presence of bioactive compounds.
Biological assays showed low antioxidant activity with IC₅₀ values of 155.02 µg/mL for the ethyl acetate extract and 226.53 µg/mL for the methanol extract.
Sequential extraction involved using solvents of increasing polarity, and techniques such as nuclear magnetic resonance were employed for compound identification.
Findings suggest potential applications in phytomedicine, although the moderate antioxidant activity raises questions about efficacy.
