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: It is undeniable that a lot of patients worldwide suffer from different types of wounds. The complex process of wound healing has a severe effect on the life quality of patients as well as causing an economic load on healthcare institutions. Although the availability of various therapies for managing patients with acute and chronic wounds for the past decade, these therapies are usually expensive and accompanied by undesirable side effects. Hence, the discovery of a new arsenal for wound healing remains a hot topic of research. Recently, plants and their by-products have garnered remarkable attention as a source of therapeutic agents to treat wounds. This is because medicinal plants provide a rich reservoir of phytochemicals that could potentially become affordable and effective therapeutic agents. Eurycoma longifolia Jack or Tongkat Ali (TA), is one of the well-known traditional plants of Malaysia, it has been scientifically proven to have medicinal properties. Hydrogels are hydrophilic polymer networks that can imbibe a significant number of fluids. In comparison to other systems developed for herbal medicines delivery, a unique power possessed by hydrogels is the high-water absorption ability. This ability has favoured the loading of herbal formulations, which are in general hydrophilic in nature, into hydrogels. Objective: The aim of this study is to prepare Eurycoma longifolia Jack (E.l.J) Tongkat Ali (TA) roots hydrogel for wound application. Methods: Authentication of Eurycoma longifolia Jack roots was done by microscopic examination using methylene blue and Lugol{\textquoteright}s iodine solution. Root extraction by Soxhlet technique. In vitro cytotoxicity of ethanol extract of the roots was evaluated in human primary gingival fibroblasts cells. The ethanolic extract was loaded into hydrogel as a suitable dosage form for further wound healing studies. Results: The crude herbal drug sample, TA present the same microscopical characters to that of E. longifolia Jack tap root. Ic50 was 118.5 μg/mL. The hydrogel was prepared using 2\% xanthan gum and ethanol extract of TA was loaded successfully for its later application as a wound healing agent.

Introduction: Eurycoma longifolia jack (E.L) is a herbal medicinal plant of South-East Asian origin, popularly recognized as {\textquoteleft}Tongkat Ali.{\textquoteright} The plant roots have been scientifically proven to have many biological effects including antibacterial activity however, no previous research to date has studied the effect on oral pathogens including cariogenic bacteria. This study was done to determine the antibacterial and antifungal activities of E.L. root extract against three common oral pathogens. Material and Methods: The microorganisms used were Candida albicans, Streptococcus mutans and Lactobacillus casei. E.L root was extracted using soxhlet method. Disc diffusion assay was conducted using extract concentration of 200 mg/ml. Nystatin and Ampicillin were used as positive control for fungal and bacterial tests respectively. Minimum Inhibitory Concentration (MIC) was done to determine the lowest inhibitory concentration of the extract on the microorganisms. Results: E.L extract inhibited the growth of Candida albicans and Streptococcus mutans at a concentration of 200 mg/ ml with a zone of inhibition of 16.0 {\textpm} 3.0 mm and 7.0 {\textpm} 1.0 mm respectively. There was no antimicrobial effect of the extract on Lactobacillus casei. The MIC of E.L extract against both Candida albicans and Streptococcus mutans was 25 mg/ml. Conclusions: The results from this study revealed the potential use of Eurycoma longifolia jack as an antimicrobial agent which can be used to produce new oral care products.

Eurycoma longifolia Jack (Tongkat Ali) roots are used in traditional medicines for its wide range of biological effects. The process of extracting out this essential oil from the plant requires a delicate and efficient method. In this research the extract of the essential oil of Eurycoma longifolia\’s root using Microwave Assisted Extraction (MAE), Soxhlet Extraction and Conventional Steam Extraction (CSE) methods, is characterized to identify the components of essential oil extracted and then to compare the yield percentage and components of the extracts from both methods. The extract obtained was characterized using gas chromatography mass spectroscopy (GC-MS) by comparing the compositions of components present in commercial Tongkat Ali oil stored in the GC-MS library. The findings showed that the MAE gives a maximum yield percentage of 5\% with six chemical components extracted in 20 min while SE and CSE gives high yield percentage of 28.3\% in 3 h and 2.5 \% in 6 h respectively with only three chemical components extracted. Therefore, MAE is the optimum method for extracting essential oil from Tongkat Ali with a high quality.
