Methoxyl derivatives of Quercetin.
Quercetin a flavonol occurring in fruit and vegretable in food component with proven beneficial impact on health. It is one of the most potent antioxidants among polyphenols.
Quercetin has also been demonstrated to display the antiviral, antibacterial, anticarcinogenic and antiinflammatory effects. Due to its antioxidant activity, rutin protects liver cells. The phytochemicals, when administered to rats, rutin has also been found to display chemopreventive properties, acting as an agent blocking carcinogenesis induced by heterocyclic amines.

You can use DPPH and ABTS methods for evaluating antioxidant potential of your compound.
You can apply all the tested method so far for Antioxidant assay.
The DPPH and ABTS methods are thought to be the most important for evaluation of antoxidant activity. Moreover, they enable to express the obtained results as equvalent of antioxidant standard (e.g., Trolox, tocopherol, acsorbic acid, etc.), so You may present the results either as percentage of scavenging of free radicals (dpph or abts) or equivalents (mmol or g) of approprate standard,
You also may use the method named as FRAP and ORAC.
Scientist all over the world use many different methods to assess the antioxidant properties of either isolated compounds or plants. However, the following methods are commonly used: DPPH, ABTS, FRAP, Beta-carotene-linoleic acid assay and TAC. The following attachment can be of help.
This is a review article illustrating several techniques for the in vitro assay of antioxidant activity with the advantages and disadvantages of each.
Dear Prof. Vinesh Kumar
I am attaching some articles on curry leaf that cover the subject of antioxidant and other biological activities of plant extracts and pure compounds isolated from Murraya koenigii.
Good luck.
