What is the principle involved in modified brontrager test?
Borntrager's test is a chemical test for the identification of anthraquinone glycosides. Here anthraquinone glycosides are four type which O, N, S, C, and borntrager's test is use for O glycosides and modify borntrager's test use for C glycosides In this test boil test sample with 1ml of sulphuric acid in a test tube for 5min,filter while hot. Cool the filtrate and shake with equal volume of dichloromethane or chloroform then separate the lower layer of chloroform and shake it with half volume of dilute ammonia. A rose pink to red colour is produced in the ammonical layer. In some cases the anthraquinones may not answer for borntrager's test due to it's reduced form....in that time ferric chloride is used.......this test may called modified bontrager's test.........

How do you perform Phytochemical screening?
Phytochemical screening - is a process of tracing plant constituents. For example you want to found out if a certain plant contains alkaloids (a plant constituent) then, you will be performing a phytochemical screening procedures for alkaloids (in this case mayer's and Wagner's test). There are general plant constituents that can be performed with a standard test. And these are screenig for: Alkaloids Saponin glycosides Cardenolides and Bufadionolides Flavonoids Tannins and Polyphenolic compounds Anthraquinones Cyanogenic glycosides Carbohydrates Fixed oils, Fats, and Volatile oils.
