Plumbago zeylanica Linn. is a useful medicinal plant. The various part of the plant contains Plumbagin, napthoquinone and other active chemical constituents, which exhibits various medicinal properties. The leaves of Nicotiana tabacum contain high amounts of the key flavor component cembranoids. Tobacco  and ß-2,7,11-cembratriene-4,6-diols display potent anticancer activity. The aim of present study is to compare in vitro antioxidant activity in both the plant. Determinations of their in vitro antioxidant activity were carried out by using DPPH radical scavenging activity method and reducing power assay method. Results of the present study indicated that the methanolic extract of Plumbago zeylanica Linn. is better antioxidant in comparison to Nicotiana tabacum Linn.
