Phytochemical constituents, ferric reducing and radical scavenging activities of helichrysm caespititium

Helichrysm caespititium is used for the treatment of viral infections and respiratory ailments. This study aimed to determine the phytochemical constituents and antioxidants (using ABTS, DPPH and FRAP) of H. caespititium water and methanol extracts. The phytochemical analysis revealed the presence of flavonoids, phytosterols, tannins, glycosides etc. Whilst the alkaloids were absent. Quantitative analysis of total phenols using both methanol and water extracts yielded high values of (839,1 and 531) GA/mg indicating rich phytochemical constituents from this plant. Whilst flavonoids from methanol and water extracts yielded (324 and 58) mg GA/mg, respectively. Results obtained from FRAP water and methanol extracts were 20,42% and 2,36% respectively; DPPH water and methanol extracts results were 92,62% and 80,56% respectively; and ABTS water and methanol extracts were 93,64% and 97,68%, respectively. These findings support the potential of H. caespititium as the potential source for the development of antioxidant-based therapies and health-promoting products.
