One of the most ancient human medical techniques is the use of plants to treat, prevent, and cure diseases. These plants can manufacture a wide variety of natural chemicals. The present study aimed to evaluate the antibacterial activity and antioxidant capacity of ethanolic extract of four plant species (Zizyphus lotus, Lavandula dentata, Ruta graveolens, and Dodonaea viscosa). Using disc diffusion and serial dilution procedures, the antibacterial abilities of these EtPEs were evaluated. The antioxidant properties were evaluated by the FRAP method and the Folin-Ciocalteu technique was used to measure the total phenolic content. Different plant extracts showed different inhibitory effects on the tested bacteria in a dose-dependent manner. Among the tested plant extracts, D. viscose exhibited the highest antibacterial activity against P. vulgaris and S. aureus, with a minimum inhibitory concentration (MIC) value of 0.5 mg/ml. On the other hand, R. graveolens displayed the highest quantity of phenolic compounds and demonstrated the highest antioxidant activity. Notably, there was a positive correlation observed between the antioxidant activity of the plant extracts and their total phenolic content. In conclusion, the findings of this study suggest that the tested plant extracts hold potential as promising sources of natural antibacterial and antioxidant agents.

The extracts were evaluated for their in vitro antioxidant property by DPPH assay, as well as their phenolic and flavonoid contents. Results: ME exhibited a strong α-glucosidase inhibition activity (IC50 271.97 μg/ml) compared to EAE and acarbose (IC50 of 1745.05 and 823.99 μg/ml, respectively). A low dose of ME gave an additive inhibition on α-glucosidase when combined with acarbose. By a kinetic analysis, ME was found to inhibit α-glucosidase in a mixed-type inhibition. Both ME and EAE showed strong antibacterial activities against gram negative and positive bacteria. The strongest inhibition was observed against C. violaceum and S. mutans for ME (MIC of both 0.387 mg/ml) and P. aeruginosa for EAE (MIC 2.938 mg/ml). Both extracts showed weaker antioxidant activities than standards; IC50 664.73 and 4225.40 μg/ml, respectively. ME was rich in phenolics (277.54 mg GAE/100 g DW), unlike EAE (1.86 mg GAE/100 g DW). Conclusion: This study can recommend B. javanica seeds as a source for antidiabetic and antibacterial agents. Combination with acarbose may have important role for the treatment of diabetes mellitus.

Background: There are 1,200 oral species out of which 400 are potentially important and 20 organisms are periopathic. Periodontal flora plays the important role in initiation and progression of periodontal diseases. There are various conservative and surgical procedures to treat and prevent periodontal diseases. Local drug delivery agents reduce microbial burden, blocks collagenase activity and inhibits bone loss; out of which tetracycline is common in use. Unwanted side effects and resistance of microorganisms towards antibiotics due to their widespread use have modified the general prescription about their efficacy. Various researches elucidate that herbal extracts exhibit wide range of antibacterial activity. In recent years, Lemongrass essential oil gains scientific interest as it targets even the periodontal pathogens. The purpose of this study is to comparatively evaluate the antibacterial activity of lemongrass essential oil with that of tetracycline. Aim and objective: To comparatively evaluate the antibacterial activity of lemongrass essential oil with tetracycline against Streptococcus mutans, Staphylococcus epidermidis and Lactobacillus and to determine the minimal inhibitory concentration of lemongrass essential oil. Study design: In vitro. Materials and Methods: It is an in vitro study done to demonstrate the antimicrobial activity of lemongrass against the oral microbes. Based on their involvement in various clinical conditions Streptococcus mutans, Staphylococcus epidermidis and Lactobacillus were selected for the study. These organisms were inoculated to a solid media and incubated overnight aerobically at 37{\textdegree}C to obtain a pure culture. The culture was made as a suspension in sterile saline with the turbidity matching 0.5 Macfarland standard. This is used to make a lawn culture on the Mueller Hinton Agar. Antimicrobial effect of tetracycline was tested using standard disc of doxycycline 30 mcg (Himedia, SD012) and sterile disc was used to prepare lemongrass essential oil which contained 10 μl, 15 μl and 20μl. In each category 5 discs were tested to get a mean zone of inhibition. After 24 hours of incubation the zone of inhibition was measure in mm using a scale. The measured zone size was tabulated and compared among the groups. Results: The minimal inhibitory concentration of lemon grass essential oil was estimated to be 10μl. Statistically significant zone of inhibition and antibacterial zone was greater in lemongrass essential oil than tetracycline for Streptococcus mutans and Staphylococcus epidermis. Conclusion: Lemongrass essential oil showed higher antibacterial activity than tetracycline. Hence, it can be used as a good alternative to tetracycline or adjunctive in the treatment of periodontitis.
