The plant Justicia simplex D.Don is traditional herb, people used it in different diseases, they treat fever and burning of the body, strengthen the lungs, the teeth and stop vomiting. The plant exhibited more promising bacterial activity against various microorganisms. Hence, in the present study this plant is also tested against the dental pathogens. The plant was extracted from four different solvents was tested for the presence of phytochemicals in it. After analyzing, its antimicrobial activity is tested against fungi and bacteria. Then a dental carrier Streptococcus aureus, Klebsiella pneumonia, Escherichia coli and Pseudomonas aeruginosa which was collected from the K.S.R. Institute for Dental Science and Research. The isolates were used to check the activity against Justicia simplex D.Don. Based on the positive result obtained against various analyses, it is formulated successfully into a tooth paste. The present study on Phytochemical screening of Justicia simplex D.Don a valuable medicinal plant extract against Dental pathogens enables the use of this plant for the formulation of tooth powder against dental pathogens. The result is more effective against dental pathogens by herbal tooth powder.

Crinum defixum Ker - Gawler is a bulbous herb which has widely used in indigenous medicine for many diseases; mainly leaf and bulb extracts are of medicinal importance. Leaf extract is used as a treatment for pimples, body-ache, dropsy, carbuncle, paronychia, leprosy, fever and diarrhoea. The bulbs are crushed and applied on to piles and itching. The present study to determine the possible phytochemicals and antimicrobial activity of various leaf extracts of Crinum defixum Ker - Gawler plant. The phytochemical screening demonstrated the presence different types compound like flavonoids, tannins, phenolic compounds, saponins and glycosides. The ethanol, methanol and crude extracts of Crinum defixum Ker - Gawler showed significant antibacterial activity against Escherichia coli, Staphylococcus aureus, pseudomonas aeruginosa, proteus vulgaris and antifungal activity against Candida albicans, Aspergillus flavus when compare to different concentrations (μg/mL). The antimicrobial potential of test compounds was determined on the basis of mean diameter of zone of inhibition around the disk in millimetres. Thus, the present findings revealed the medicinal potential of Crinum defixum Ker - Gawler to develop a drug against various human ailments.

Preliminary phytochemical screening of various extracts of Amoora ruhituka bark were investigated which reveals the presence of several secondary metabolites in each extracts. The antibacterial activity of all the extracts was tested against four gram negative bacterial strains. The results indicated the zone of inhibition which ranges from 11.30±577 to 18.7±0.577 for different extracts in which Methanol extract has shown highest zone of inhibition for Salmonella typhimurium followed by Enterobacter aerogenes , E coli and P aeruginosa whereas benzene extract has showed the least zone of inhibition and the minimum inhibitory concentration (MIC) of the different extracts ranging from 0.78 mg/ml to 6.25mg/ml.The complete results of this study provides a essential data for the use of Amoora ruhituka for the treatment of infection associated diseases.
