Description
Summary:The present study was aimed to investigate in vitro [alpha]-glucosidase inhibition, antioxidant, anticancer, and antimycobacterial activities of the ethyl acetate extract of A. tamilnadensis leaves. The extract recorded strong [alpha]-glucosidase inhibition with an IC^sub 50^ value of 100 [mu]g/ml. The antioxidant potential of the extract was evaluated by nitric oxide radical inhibition, lipid peroxidation inhibition, ferric thiocyanate, and ABTS radical scavenging assay, and the extract recorded significant antioxidant activity. The ferric thiocyanate activity of extract was superior to butylated hydroxyl anisol (BHA), the standard antioxidant agent. The anticancer activity of the extract was evaluated against (1) breast cancer cell lines (MDAM B-231), (2) cervical cancer cell lines (HeLa), and (3) lung cancer cell line (A 549) using MTT assay, and significant activity was recorded against A 549 with an IC^sub 50^ value of 64 [mu]g/ml. Further studies on the morphology, acridine orange/ethidium bromide staining, and cell cycle analysis by flow cytometry confirm the extract-induced apoptosis in A 549. This extract also recorded significant anti-tuberculosis activity against Mycobacterium smegmatis. The current study suggests that the ethyl acetate extract of A. tamilnadensis is a potential source of natural [alpha]-glucosidase inhibitor and antioxidant for protection as well as prevention of life-threatening diseases like cancer.
