In this article we will discuss about the tests for estimation of ascorbic acid in plants. Principle: Ascorbic acid oxidase acts on the substrate ascorbic acid to form dehydro-ascorbic acid. The residual ascorbic acid content is determined by titration using a dye solution (Dichlorophenol indophenol, an oxidation-reduction dye): Requirements: (a) Reagents: 1. Dye solution: 15 mgm of 2-6 dichlorophenol indophenol [...]
In this article we will discuss about the tests for detection of fats and oils in plants with the help of experiments. Fats and Oils are invariably present in all living cells. They are synthesized through an active metabolism and also serve a number of indispensable roles in physiological processes. Fats are the esters of fatty acids with glycerol and [...]
In this article we will discuss about the tests for estimation of amylase in plants. Principle: The reducing sugars produced by the action of α- and or β-amylase react with di-nitro-salicylic acid and reduce it to a brown coloured product, nitro-amino-salicylic acid. Materials: i. Sodium acetate buffer, 0.1 M pH 4.7 ii. Starch 1% Solution: Prepare a fresh solution by [...]
