Andrographis echioides

The present research was focused in standardizing the callus induction technique and studies the behaviour of callus in secondary metabolite production in Andrographis echioides (L.) Nees. In this study, the leaf bits of Andrographis echioides responded positively for callus induction. Earliest (21.00 days) and profuse callusing was observed on MS medium supplemented with 2, 4-D (2.0 mgl-1 ) + NAA (2.0 mgl-1 ) + BAP (2.0 mgl-1 ).

Among all the species of Andrographis, Andrographis echioides is given importance recently for its excellent medicinal properties. The study of Andrographis echioides as anti-microbial agent was found necessary for gaining insight into this medicinal flora and its real value. The ethyl acetate extract of leaves recorded highest anti-fungal activity against all the selected pathogens viz., Pythium aphanidermatum, Phytophthora capsici, Macrophomina phaseolina...
