- <p>Medicinal plants are important sources for isolation of pharmaceutical drugs. The current available <br>drugs are in many ways either inefficient or unaffordable to ever increasing forms of microbial <br>infections. Screenings of medicinal plants used by the traditional medicinal healers are the main sources <br>for formulation of herbal drugs. Phytochemicals present in plants are economically important sources <br>of drugs, fragrances, pigments, food additives and pesticides Lawsonia inermishas maximum contents <br>of tannin. The present study was carried out to comparatively evaluate the phytochemical constituents <br>of Centella asiatica and Lawsonia inermis using methanolic and ethanolic extracts, respectively. <br>Qualitative phytochemical screening was performed using standard chemical tests to identify alkaloids, <br>flavonoids, tannins, saponins, glycosides, carbohydrates, phenolic compounds, and terpenoids. <br>Alkaloids were detected using Dragendorff’s, Mayer’s, and Wagner’s tests, while flavonoids were <br>confirmed by Shinoda, zinc–hydrochloride reduction, and lead acetate tests. The study provides <br>scientific support for the traditional medicinal uses of these plants and suggests their potential for further <br>pharmacological investigation. </p>
