Phytochemical screening methods

On a recent survey conducted by the World Health Organization (WHO) globally, around 20,000 Medicinal plants are being used profusely either in pharmaceutical industry or in folk medicines. Interestingly, about 1.4% do possess well-established, widely—proven and broadly accepted unequivocally active constituents (Kar, 2007).
Plants known to contain food and mixture of extraordinary chemicals, some of which act beneficially to human and others may have detrimental effects. From many wild plant species, nothing is known as regard their chemical makeup beyond the fact that most contain carbohydrates, fats, protein and chlorophyll (Ngbede et al., 2008). However, the majority of herbal substances used in the manufacturing of medicinals is not or only cursory described in a monograph of pharmacopoeia, especially, if it is only used regionally and/or in traditional medicine. Thus, a researcher has to develop specific methods of phytochemical analysis, with priority on a qualitative and quantitative assay method, to monitor the quality of the product (Harnischfeger, 2005).
