Abstract
Leaf of Stevia rebaudiana Bertoni contains steviol glycosides which are extremely sweet compounds and are consumed world wide as low caloric sweetener. The compound responsible for the sweetness is a stevioside whose concentration is found different during various leaf stages. Throughout the development of plant the activity as well as isoforms of several enzymes is also found variable. Here, we studied the activity as well as pattern of isoforms of peroxidase and esterase in young leaf, the leaf just before flowering stage and the leaf after flowering stage of Stevia rebaudiana. The results showed significant variation in activity as well as isozyme banding pattern during different stages of growth.
