Total flavanoid contents

In present investigation, methanolic extract of different marketed Aegle marmelos formulations (F1, F2, F3, and F4) screened for determination of total phenolic and flavanoid contents.  Highest phenolic (6.145 ± 0.05 mg/kg) and flavonoid (8.134 ± 0.044 mg/kg) contents were noticed in formulation F4. Free radical scavenging activity of all the studied formulations were evaluated by using DPPH (1,1-Diphenyl-2-picryl hydrazyl) method. Whereas, each formulation showed good scavenging of DPPH radical with IC50 values (F1-2.185, F2-2.216, F3-2.243 and F4-2.143 µg/ml), and is comparable to standard compounds (BHT, ascorbic acid and rutin).
