Antioxidant activity of four sample extracts of T. neotaliala determined by DPPH, ABTS, CUPRAC, and FRAP assays.
The antioxidant results were statistically analyzed by one-way ANOVA using SPSS software, that the antioxidant content of each sample extract was significantly different from the antioxidant content of others (p-value < 0.05) which indicated that each solvent had a different capacity to extract phytoconstituents depending on its polarity and chemical structure.
