Abstract
In the current study, we carried out a comparative analysis of qualitative phytochemical screening and the antioxidant activities of 75% Ethanol, Acetone, Chloroform, Petroleum ether and aqueous extracts of the selected species (Mentha arvensis, Allium porrum and Elettaria cardamomum) was studied. Five solvents via; 75% Ethanol, Acetone, Chloroform, Petroleum ether and aqueous were used to obtain extracts from powdered plants parts. The extracts were subjected to qualitative Phytochemical screening using standard procedures. Antioxidant activity of the five extracts using free radical scavenging assays like DPPH was determined. It was observed that presence of greater amount of phenolic compounds leads to a more powerful radical scavenging effect as was shown by ethanolic extract of the leaves and seeds when compared to the other extracts investigated by us during flavonoids and phenol test. Mentha arvensis leaves exhibited the maximum content of phenols and flavonoids compounds hence greatest antioxidant profile when compared to two other plants.
