چکیده
The attractive colours and fragrance produced by the plants is due to specific phytochemicals present in them. They may be tannins, flavonoids, glycosides, saponins, steroids and alkaloids. Emblica officinalis, Acacia catechu, Acacia concina and Hibiscus rosa-sinensis, are medicinal dye yielding plants belong to different families. The qualitative analysis carried out for these plants showed that tannins, saponins, flavonoids, terpenoids and alkaloids are present in all the plants except phlobatannins that is only present in Acacia catechu. The pet ether and chloroform extract of Emblica officinalis does not show potential for oil and fat components where as all the extract of Emblica officinalis showed positive test for carbohydrates. The identification of colouring chemical constituents of natural products together with their therapeutic properties is discussed.
