Introduction: The roots of E. longifolia jack (E.L.) or Tongkat Ali have been used in traditional medicine as well as supplements and food additives. Many chemical compounds have been detected in extracts of its roots which are believed to be responsible for its medicinal properties. In this study, our objectives were to study the effects of EL root extracts on the growth of Streptococcus Mutans, Lactobacillus and Candida Albicans isolated from saliva of adult patients with high caries risk. Materials and Methods: The ethanolic extract of the root of this plant was tested against saliva isolated Streptococcus Mutans, Lactobacillus and Candida Albicans via disc diffusion assay at a concentration of 200mg/mL. The minimum inhibitory concentration was carried out by the standard broth microdilution method. Cell viability of test microorganisms against different concentration of the extract and inhibition zones were calculated. Results: Disk diffusion assay showed positive zones of inhibition for all test microorganisms with S. mutans, Lactobacillus and C. albicans exhibiting zones of inhibition of 8.3 {\textpm} 0.7mm, 12.4 {\textpm} 2.4mm and 21.4 {\textpm} 2.7mm respectively. For minimum inhibitory concentration, the test microorganisms were tested at concentration of 250mg/ mL, 125mg/mL, 62.5mg/mL, 31.3mg/mL and 0mg/mL. The minimum inhibitory concentration showed that MIC of S. mutans was at 62.5mg/mL, Lactobacillus at 125mg/mL and C. albicans at 31.3mg/mL. Lastly, the cell viability results supported the MIC determined prior. Conclusion: Ethanol-based E. longifolia Jack root extract has an antimicrobial effect on the following microorganisms isolated from the saliva of high-risk caries adult patients: S. mutans, Lactobacillus and C. albicans.

Background: Thespesia populnea L. commonly known as tulip tree or \‘portia\’ tree has been traditionally used for different illnesses. Thespesia populnea L. is considered to have high tannin content and have high therapeutic value. Purpose: The antifungal and antibacterial potential of T. populnea L. should be checked on multiple drug resistant opportunistic pathogens Pseudomonas aeruginosa and Candida albicans in HIV/AIDS patients. Methods: In order to check the effect of antibiotics antibiogram was studied with antibiotic sensitivity discs. To study the major factor affecting resistance test on formation of biofilm was done by tube and plate methods. The dried flower powder was subjected to sauxlaut hot extraction and the crude extract was analysed by Gas Chromatography and Mass Spectrophotoscopy. Antimicrobial potential of the ethyl acetate extract of the flower was checked by well agar diffusion, UV Spectrometry for growth rate and docking of selected compounds on the microbes of our study by the application of a software. Results: The tested extracts and the selected compounds have showed significant results in the antimicrobial activities against the opportunistic pathogens in human. Higher the concentration of the extracts better is the inhibition of microbes. Conclusion: The study provides a scientific rationale for the traditional use in the management of opportunistic pathogens which are multidrug resistant.
