Bio-Chemical Tests for the Detection of Naphthoquinones

Bio-Chemical Tests for the Detection of Naphthoquinones

Juglone test: Treat 2 ml of extract of chloroform and 2 ml of ethyl ether with dilute ammonia solution. If pink colour is obtained, it indicates the presence of naphthoquinones. Dam-Karrer Test: To the chloroformic plant extract, add 10% potassium hydroxide solution, blue colour is developed which indicates the presence of naphthoquinones.
