Test for carbohydrate through Molisch's test indicated their presence in chloroform extract as well as rectified spirit extract, but the results were somewhat variable in Fehling's and Barfoed's tests.
After hydrolysis, the presence of carbohydrates in the hydrolyzed samples was investigated by different biochemical tests including Molisch Test, Iodine Test, Benedict's Test, Tollen Test, Barfoed's Test, Fehling's solution Test, Osazone Test, Seliwanoff's Test and Bial's Test.
A number of biochemical tests including Fehling's Solution Test, Benedict's test [23], Combur Test [11], Molisch Test, Iodine Test [24], Tollen Test, Barfoed's Test, Osazone Test and Seliwanoff's Test were performed by using the reported methods (Fig.
A number of chemical tests including Molisch Test, Iodine Test, Benedict's Test, Tollen Test, Barfoed's Test, Fehling's solution Test, Osazone Test, Hydrolysis Test and Seliwanoff's Test have been found to be positive and strongly support for the presence of reducing sugars and other carbohydrates in the water extracts of M.
