Phytochemical screening, GC-MS analysis and in vitro antioxidant activity of pollen of Centella asiatica (Linn) urban a traditional medicinal plant.

In the present study the crude extracts of pollen of Centella asiatica (Linn.) Urban were explored for their antioxidant potential using Ferric Reducing Power, Metal Chelating Activity and Trolox Equivalent Antioxidant Capacity assays. In crude extracts of pollen antioxidant components were initially extracted in methanol and further fractionated in solvents of different polarity, such as n-Hexane, Chloroform, Ethyl Acetate and Water exhibited reasonable antioxidant activity.

In vitro antioxidant potential and free radical scavenging activity of various extracts of pollen of Typha domigensis Pers.

Antioxidant potential of the pollen of Typha domigensis Pers. using Ferric Reducing ower, Metal Chelating Activity and Trolox Equivalent Antioxidant Capacity (TEAC) assays has been carried out in the current research work. The antioxidant components were initially extracted from the pollen in methanol and were further fractionated in solvents of different polarity such as n-Hexane, Chloroform, Ethyl Acetate and Water.

4-n-Butyl-3-(3-methyl-phen-yl)-1H-1,2,4-triazol-5(4H)-one.

In the mol-ecule of the title compound, C(13)H(17)N(3)O, the two rings make a dihedral angle of 56.63 (13)°. Mol-ecules are linked by strong N-H⋯O inter-molecular hydrogen bonds into chains running along the c axis.
