Production of bioethanol from renewable carbohydrates materials has become worldwide interest. Floral wastes are easily, freely and abundantly available bio resource which has distinct advantages such as high fermentable sugars and zero investment. In this paper the  production of ethanol from golden trumpet flower (Allamanda schottii L) by fermentation using yeast Saccharomyces Cerevisiea was studied. The optimization of various parameters for the production of ethanol and emission testing with the blend of petrol and ethanol has been studied. The flower of this study allamamda contains 65% total sugars. The yeast strain Saccharomyces Cerevisiea was purchased from local super market as baker’s yeast. The ethanol obtained was maximum 18.75 ml for 100 ml slurry composition by optimizing various parameters like slurry composition as 1: 8, pH as 5.5, inoculum age as 72 hours, inoculum level as 3.75 g 100 ml-1, temperature at 35p  C and fermentation period as 5 days. Maximum production of ethanol is obtained by the addition of urea. This method can be tried for large scale ethanol production from Allamanda Schottii flowers.
