497-5032H-Chromenylmethylene benzohydrazides 6a-t have been prepared by the reaction of 2H-chromene-3-carbaldehydes 4a-e with benzohydrizides 5a-c and isonicotinohydrazide 5d in ethyl alcohol at room temperature. All the synthesized compounds have been evaluated for their anti-microbial activity. Compounds 6a, 6f, 6p and 6t have potent anti-bacterial activity. Compounds 6a and 6f are highly potent and 6l, 6p and 6t have equi potent anti-fungal activity
