Total phenolics content
Folin–Ciocalteu reagent is mixture of phosphomolybdate
and phosphotungstate. Phenolic compound cause the
reduction of phosphotungstate-phosphomolybdate complex
to blue reaction products in alkaline conditions and
the estimation of phenolics involves the measurement
of the absorbance of this colored complex at 765 nm.
It measures the amount of the substance need to inhibit
the oxidation of the reagent. The total phenolic content
was expressed in terms of % Gallic acid. Results were
reported in Table 1.
