📌 3 Key Takeaways
🎯
Objective & Hypothesis:The aim of this research work is the determination of total phenols, flavonoids, condensed tannin levels, and antioxidant power of methanolic and aqueous extracts of Zizyphus lotus L and Glycyrrhiza glabra L roots, using three methods (Test DPPH, bleaching of β-carotene and hemoglobin denaturation protection).
📊
Key Findings & Data:The higher levels of total phenols were found in methanol extracts of G. glabra and Z. lotus (58.94 ± 0.05 and 51.80 ± 0.02 mg GAE/ g of extract, respectively), the methanol extract of Z. lotus was the richest in flavonoids and tannins condensed with the content of 16.00 ± 0.01 and 17.22 ± 0.1 mg CE/g of extract respectively.
