Invitro antioxidant activity of selected antiasthmatic herbal constituents.

Asthmatic patients are more subjected to continuous oxidative stress. Roosting the antioxidant defenses of asthma patient could be beneficial as it may help thwart symptoms of the lung disease and asthma. Considering these facts different plant extracts and phytoconstituents with proven anti asthmatic property had been subjected to antioxidant study at various combinations using Diphenyl Vicryl Hydrazyl radical scavenging method, Hydrogen Peroxide radical scavenging method, Nitric oxide radical inhibition method, ABTS radical scavenging method and Lipid peroxidation assay method.All the selected herbal based constituents and extracts at different combination showed a potent antioxidant activiy by Nitric oxide radical inhibition activiy method followed by ABTS method. The present finding suggests that the selected plant based anti asthmatic constituents namely Coleus extract (10% Forskolin), Piper longum extract (20% Piperine), CurcuminC3Complex (60% Curcumin), Vasaka (30% Vasicinone), Forskolin (95%), Pperine (98%), Curcumin C3 Complex (98.5%) and Vasicinone (75%) could be utilised in alternate anti asthmatic therapy, since they play a vital role in scavenging Nitric oxide which could prevent the bronchial inflammation in asthmatic patients.
