ABSTRACT. The present study aimed to evaluate the in vitro antimicrobial activity of pharmacologically important Adhatoda vasica plant extracts. Plant Adhatoda vasica L. Nees (Acanthaceae) commonly known as Malabar nut is an evergreen two – three m tall shrub, sometime used as. Adhatoda vasica (L.) (Acanthaceae) is used in the indigenous system of medicine in India. The alkaloid Vasicine was isolated from ethanolic extract of the .

Abstract Adhatoda vasica L. Antimycobacterial activity of two natural alkaloids, vasicine acetate and 2-acetyl benzylamine, isolated from Indian shrub Adhatoda vasica Ness.

The combined chloroform extract was washed with water, dipped, and dried vasoca anhydrous sodium sulphate. Extraction Shade dried and coarsely powdered leaves of A. Cytotoxicity of each sample was expressed as IC 50 value. The spot turned orange red on spraying with Dragendorff’s reagent.


Cytotoxic studies against A lung adenocarcinoma cancer cell line showed Vasicine acetate to be the most potent compound Table 4. Streptomycin was used as positive control for adhatpda and Ketoconazole as positive control for fungi.

Microbial Organisms The following Gram acyivity, Gram positive bacteria, clinical isolates, and fungi were used for the experiment: The cytotoxicity was determined according to the method of Balachandran et al.

DPPH 2,2-diphenylpicrylhydrazyl radical scavenging activity of Vasicine acetate was determined based on the method of Wang et al.

The antifungal agent Ketoconazole for fungi and antibacterial agent Streptomycin for bacteria were included in the assays as positive controls. Glossary of Indian Medicinal Plants. Vasicine acetate showed minimum inhibitory concentration values against bacteria: Preliminary phytochemical and antibacterial screening of crude extract of the leaf vasia Adhatoda vasica.

Vasicine acetate showed antimycobacterial activity [ 15 ]. Mobile phase A consisted of water with 0.


The plant is used in the indigenous system of medicine in India and is a well-known expectorant in both Ayurvedic and Unani Systems of Medicine [ 45 ]. The MIC for fungi was defined as the lowest extract concentration, showing no visible fungal growth after incubation time. Medicinal plants are important sources of practical drugs for people throughout the year.

The extract was filtered through Whatman No. The required concentrations, Accumulation of vasicine and vasicinone in tissue cultures of Adhatoda vasica and evaluation of the free radical-scavenging activities of the various crude extracts.
