- Abstract
The different parts of Calotropis gigantea and Vinca rosea belonging to the families of Asclepiadaceae and
Apocynaceae were studied for their antioxidant and antimicrobial activities against selected bacterial strains. From the
results it was evident that the flower of Vinca rosea showed the highest antioxidant activity of 97.44% at 800 μg which
was higher than the standard L-ascorbic acid (94%) and Calotropis gigantea showed the least. Calotropis gigantea
exhibited highest inhibition zone of 14, 14 and 11 mm against Escherichia coli, Salmonella typhi and Shigella sonnei
when compared to Vinca rosea. Hence, the present study supports the view, that these medicinal plants might be
useful as antioxidant and antimicrobial agents.
