The Molisch test can be the primary test to be performed when one wishes to find out whether carbohydrate molecules exist or not in the sample. Molisch is used to identify sugars like mannose, fructose, glucose and many more. Molisch tests can be used to identify all kinds of sugars like trisaccharides, disaccharides and monosaccharides .The Molisch test used to identify monosaccharides, disaccharides, and polysaccharides. The Molisch test is performed by adding a few drops of the carbohydrate solution to a few drops of hydrazine sulfate. The solution is then mixed and allowed to stand for a few minutes. If carbohydrates are present, a purple-red color will develop.ninhydrin testMolish反应：糖在 浓硫酸 或 浓盐酸 的作用下脱水形成 糠醛 及其衍生物与 α-萘酚 作用形成紫红色复合物，在糖液和浓H2SO4的液面间形成紫环，因此又称紫环反应。. 中文名.

Transfer 8-10 drops of this solution to a small test tube. (Save the rest of it for step 11.) In a separate tube, mix together 1 mL of. Fehling’s solution A with 1 mL of Fehling’s solution B. Add this mixture to the small test tube containing your hydrolyzed starch, and heat for a few minutes in a boiling water bath. Molisch’s test is a sensitive chemical test, named after Australian Botanist Hans Molisch. It is a chemical test used to detect the presence of carbohydrates, specifically the presence of any form of carbohydrate that can be hydrolyzed to form simple sugars, such as glucose. The objective of Molisch’s test is to identify the presence of .
Molisch Test. Molisch Test is a confirmatory qualitative test for carbohydrates. α-naphthol in ethanol is called molischs reagent, which is added to a carbohydrate-contained sample in a test tube. After that, a few drops of sulphuric acid are added to it. Ultimately, a purple ring is generated in the middle of the test tube.
