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 .

Ignacimuthu and Shanmugam [ 15 ] have reported the antitubercular activity of Vasicine acetate isolated from A.
Antibacterial activity of adhatoda vasica leaf extract
Antimycobacterial activity of two natural alkaloids, vasicine acetate and 2-acetyl benzylamine, isolated from Indian shrub Adhatoda vasica Ness. The fraction was further purified and the compound Vasicine was isolated.
Vasicine acetate could be checked further in drug discovery programme. The plant is used in the indigenous system of medicine in India and is a antimicorbial expectorant in both Ayurvedic and Unani Systems of Medicine [ 45 ]. The spot turned orange red on spraying with Dragendorff’s reagent. Nature acts as a prominent reservoir for new and novel therapeutics. Cytotoxicity of each sample was expressed as IC 50 value.
A voucher specimen No. Vasicine acetate could be probed further in drug discovery programme. Antimicrobial and antimycobacterial activities of methyl caffeate isolated from Solanum torvum Swartz. The chemicals are given in delta scale acttivity TMS as an internal standard. Support Center Support Center.
