Antioxidant, free radical scavenging and invitro cytotoxic studies of ethanolic extract of Leucas indica var lavandulifolia and Leucas indica var nagalapuramiana

The main focus of the study is to determine antioxidant, free radical scavenging and cytotoxic effect of ethanolic extract of whole plant of Leucas indica var lavandulifolia and Leucas indica var nagalapuramiana using various in vitro assay methods as well as to estimate the amount of total phenol and flavonoid contents. Leucas indica var lavandulifolia and Leucas indica var nagalapuramiana were collected in February 2008 from Thirumala hills and standard procedure from the literature were used to estimate the antioxidant and free radical scavenging activity. The results suggest that both the extracts can be considered as a valuable source of antioxidants products as the obtained values are more or less near to the used standard compound. The characterization of leucas for antioxidant and free radical scavenging activities are new to literature in this context this extensive in vitro study of the selected two species of leucas for antioxidant activity will be a valuable study for further in vivo activities.
