| Abstract:
|
The methanolic and petroleum ether extracts of Calotropis gigantea leaves were screened for phytochemical screening.
Alkaloids, glycosides, flavonides, saponins, resins and phenols etc. were detected in the leaves extract fractions. The
leaves extract of C.gigantea were also screened for antimicrobial activity. The extracts were tested against Gram
positive bacteria, Gram negative bacteria such as Staphylococcus aureus & Escherichia coli and fungi such as Aspergillus
niger & Mucor using agar well diffusion method. Both the extracts showed significant antimicrobial activity. The
petroleum ether extract of C.gigantea showed more antimicrobial activity against Staphylococcus aureus than
methanolic extract. The methanolic extract of C.gigantea showed more antimicrobial activity against Escherichia coli
than petroleum ether extract. The results confirmed that presence of antifungal and antibacterial activity in the leaf
extract of C.gigantea against the human pathogenic organisms.
