Phytochemical and pharmacological evaluation of some selected medicinal plants

ABSTRACT

The medicinal plants most commonly cultivated and medicinally useful [like Annona squamosa, Coleus forskohlii, Cissus quadrangularis, Desmodium gangeticum and Stevia rebaudiana] were selected for physicochemical, phytochemical and pharmacological studies. Physicochemical values for these medicinal plants like total ash content, acid-insoluble ash, sulphate ash, water-soluble ash, loss on drying and solubility percentage were evolved. Qualitative phytochemical tests were carried out for all these medicinal plants. Quantitative estimation of major biological active compounds, total alkaloid, total glycosides and total terpenoids was carried out. Antibacterial and antifungal activities against E. coli, Streptococcus aureus, Staphylococcus pyogenes, Enterococcus faecalis, Aspergillus niger and A. flavus were studied. TLC profiles of alcoholic extracts of all these medicinal plants were established
