Conclusion Vasicine acetate was obtained by acetylation of Vasicine lf from A. Sample ethanol extract Then the residue was crystallised from chloroform to get Vasicine acetate as colorless crystals m. The compound showed prominent cytotoxic activity in vitro against A lung adenocarcinoma cancer cell line. Classical Uses of Medicinal Plants. The plant is reported to show abortifacient [ 7 ], antimicrobial [ 89 ], and antitussive activities [ 10 activityy.

Vasicine acetate showed moderate antibacterial activity compared to Vasicine.

All melting point values are uncorrected and taken by open capillary method on a heating block Instrument. Vasicine acetate showed minimum inhibitory concentration values against bacteria: The emergence of drug-resistant pathogens and the increase in diseases affecting the immune system have greatly intensified the need to investigate new bioactive metabolites for potential pharmaceutical and industrial applications [ 12 ].


The following Gram negative, Gram positive bacteria, clinical isolates, and fungi were used for the experiment: Abstract Adhatoda vasica L.
