Vasicine acetate exhibited qctivity zone of inhibition against bacteria: Vasicine acetate could be probed further in drug discovery programme.

The radical scavenging activity of Vasicine acetate at different concentrations is shown in Table 3.

UV-Visible spectra were taken in methanol on Thermo Fisher instrument. Introduction Natural products still remain the most important source for discovery of new and potential drug molecules. Vasicine is reported to have bronchodilatory, respiratory od, and uterine stimulant effects [ 14 ].

A human adenocarcinoma cancer cell line was obtained from National Institute of Cell Sciences, Pune. The spot turned orange red on spraying with Dragendorff’s reagent.

The structure was elucidated using spectroscopic methods: Journal of Natural Products. DPPH 2,2-diphenylpicrylhydrazyl radical scavenging activity of Vasicine acetate was determined based on the method of Wang et al. The physical and spectroscopic data were compared with those reported in the literature [ 2122 ].

The extract was filtered through Whatman No. The plant contains alkaloids such as Vasicine, vasicinone, antibacteerial, vasicol, activitt, and vasicinol [ 12 ]. Vasicine acetate showed minimum inhibitory concentration values against bacteria; they were M.


Minimum inhibitory concentration studies of the compounds were performed according to the standard reference methods for bacteria [ 17 ] and filamentous fungi [ 18 ].

Streptomycin was used as positive control for bacteria and Ketoconazole as positive control for fungi. Support Center Support Center.
