Spilanthes acmella Murr., a member of Asteraceae family is commonly known as Akarkara in Hindi. It is used in ayurvedic medicines as a stimulant and sialagogue for curing stammering, tongue paralysis, stomatis, tooth ache and affections of throat and gums (Kirtikar and Basu, 1975). The various Spilanthes spp. Which are responsible for their medicinal properties contain unsaturated acid amides. Spilanthod (Deca - 2E, 6Z, 8E- trienoic acid isobutylamide) present in S. acmella produces a typical smarting sensation on the tongue which is accompanied by tingling and numbness (Gokhale and Bhide, 1945),. Spilanthol has also been reported to be highly toxic to mosquito larvae as well as the adult their contents with plant growth and development either due to their different rates of the proper developmental stage for harvesting the economic plant parts, it becomes necessary to monitor the content and yield of the active constituents in the different plant parts at the different growth and developmental stages. Keeping this in view, the present work was undertaken to study the dynamics of spilanthol in various developmental stages of the flowers.
