Phytochemical screening and antioxidants investigations of Ethyl Acetate and Acetone Leaf Extracts of Thaumatococcus danielli

The method of cold maceration was used in the extraction Thaumatococcus danielli. The results obtained from qualitative phytochemical screening of the ethyl acetate and acetone extracts of T. danielli revealed the presence of medicinally bioactive compounds such as alkaloids, steroids, flavonoids, phenols, tannins phlobatannins and saponins. The crude ethyl acetate extract of T. danielli showed inhibition of DPPH radical scavenging activity at the ranges of 27.90%, 38.12%, 61.33% 65.19%  and 61.60% with concentrations of 0.1, 0.3 ,0.5 ,0.7 and 1g/ml and that the crude acetone showed inhibition of DPPH radical scavenging activity at the ranges of 76.24%, 71.73%, 66.45%,62.26% and 54.96% with concentrations of 0.1, 0.3, 0.5,0.7, and 1g/ml and vitamin C showed minimum radical scavenging activity of 66.57% and maximum activity of 85.52%.
