In vitro Assessment of Antioxidant Activity of Anisomeles indica

The present research carried out to estimate the antioxidant activity of Anisomeles indica (L.) O. Kuntze leaves by employing some in vitro methods i.e. free radical scavenging activity, reducing ability and chelating ability. The leaves extract showed an excellent activity in all three mechanisms. TEAC (Trolox equivalent antioxidant capacity) values of A. indica range from 11.17 ± 0.239 to 0.75 ± 0.658 mMol. While the FRAP (ferric reducing antioxidant power) value and % age bound value ranges from 118.4 ± 0.495 to 14.44 ± 0.339 mM and 72.91 ± 0.770 to 56.61 ± 0.843 % respectively. The major phyto-constituents i.e. total phenolic and flavonoid contents ranges from 1145.5 ± 0.593 to 198.5 ± 0.395 mg/L of GAE and 3123.7 ± 0.395 to 1154.5 ± 0.376 mg/L of Quercetin equivalent. The results divulge that leaves of A. indica are potential source of natural antioxidants showing metal chelating, reducing and free radical scavenging abilities.
