The present study has been designed to carry out the phytochemical screening, HPTLC finger print profile and in vitro antimicrobial activity of aqueous flowers extract of Mirabilis jalapa. Preliminary phytochemical screening confirmed the presence of alkaloids, anthraquinones, glycosides, flavonoids, tannins, terpenes etc., In HPTLC analysis, quercetin bands were identified in sample chromatogram (5 and 10 μl) which was confirmed by the chromatogram obtained from the standard quercetin and by comparing retention factors of quercetin (Rf - 0.51) value is from sample and standard solution. In vitro antimicrobial activity of plant extract ( 50, 100 and 150 µg/ml) was also performed by using disc diffusion method against the pathogenic bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, and E.coli, pathogenic fungi such as Candida albicans and Trichoderma viride. 150 µg of aqueous flowers extract was active against both the bacterial and fungal species. Standard antibiotics gentamicin, amphotericin-B were also performed for antibacterial and antifungal activity respectively. The results of our study indicated that flavonoid quercetin is present in the plant extract which may responsible for potent antimicrobial activity against pathogenic microorganisms.
