WebThe Liebermann-Burchard or Acetic anhydride Test is used for the detection of cholesterol. The formation of a green or green-blue colour after a few minutes is positive. This colour begins as a purplish, pink colour and progresses through to a light green then very dark green colour. WebBurchard test was first given by the scientist Liebmann to detect the presence of cholesterol. Cholesterol reacts with the strong concentrated acid, i.e. sulphuric acid and acetic anhydride. Sulphuric acid and acetic anhydride act as a dehydrating and oxidizing agent. Method: Take crystals of cholesterol in a test tube.
