This study was based on screening antibacterial activity of the ethanol extract ofBaeckea frutescensL. against MRSA clinical isolates, analyzes the potential antibacterial compound, and assesses the cytotoxicity effect of the extract in tissue culture. Leaves ofBaeckea frutescensL. were shade dried, powdered, and extracted using solvent ethanol. Preliminary phytochemical screening of the crude extracts revealed the presence of alkaloids, flavonoids, steroids, terpenoids, phenols, and carbohydrates. The presence of these bioactive constituents is related to the antibacterial activity of the plant. Disc diffusion method revealed a high degree of activity against microorganisms. The results confirm thatBaeckea frutescensL. can be used as a source of drugs to fight infections caused by susceptible bacteria.

Skin infections most often found in developing countries, especially in the tropics, are purulent skin inflammation (pyoderma), the main cause of Staphylococcus aureus. The increasing number of cases of bacteria that are resistant to antibacterial can encourage the extraction of sources of antibacterial drugs from natural ingredients. One of the plants that is thought to have the antibacterial activity of Staphylococcus aureus is the Neem plant. In this study an antibacterial activity test was carried out with the well diffusion method from 96% ethanol extract of Mimba leaves extracted by percolation method. Previously 96% ethanol extract from Mimba leaves had been identified by secondary metabolites by phytochemical screening and standardized extract testing. Standarization using non-specific parameters (moisture content, ash content and drying losses) found that 96% ethanol extract of Mimba leaves entered a range of standard parameters and in phytochemical screening tests obtained 96% ethanol extract of Mimba leaves containing alcaloid, saponins, tannins, steroids / terpenoids and flavonoids. The results of the study on the antibacterial activity test showed a concentration of 75% ethanol extract of 96% Mimba leaves classified as having strong activity, at a concentration of 50% and 25% classified as having moderate activity. Based on this study it can be concluded that the three concentrations of 96% ethanol extract of Mimba leaves were able to inhibit the growth of Staphylococcus aureus bacteria.

Objective: The objective of this research was to investigate the preliminary phytochemical screening and antibacterial activity of Bawang Dayak(Eleutherine sp.) and Hati Tanah (Angiopteris sp.) and their combination against Propionibacterium acnes.Methods: The extracts were used for phytochemical screening. Antibacterial activity was performed using disc diffusion technique, with twovariations of the concentration of 5% and 10% for each extracts, and combination of both extracts with three combinations: (1) 5%: 5%, (2) 5%: 10%, and (3) 10%: 5%.Results: Both extracts contained tannins, saponins, and steroids. The antibacterial activity against P. acnes showed that the inhibition zones ofBawang Dayak ethanol extract were 6.1±1.5 mm (5%) and 8.7±1.3 mm (10%). On the other hand, the inhibition zones of Hati Tanah ethanol extract were 4.0±1.6 mm (5%) and 9.2±2.5 mm (10%). The inhibition zones produced in combinations 1, 2, and 3 were 5.8±0.3 mm, 10.8±2.0 mm, and 15.5±2.8 mm, respectively.Conclusion: In this study showed the presence of tannins, saponins, and steroids that might be responsible for antibacterial activity in both extract. The best antibacterial activity was produced by combining the two extracts (combination 3).

Soursop (Annona muricata L.) has been used for generations by some communities in Indonesia to treat diseases. Soursop leaves are used as an alternative treatment for cancer, by boiling them in the water and consuming it. In addition to the treatment of cancer, soursop plant is also used for the treatment of skin diseases such as boils. This study aimed to determine the antibacterial activity of ethanol extract of soursop leaves of young and old against Staphylococcus aureus, determine the content of secondary metabolites, and find out the diameter of inhibitory young leaves and old leaves of soursop in inhibiting Staphylococcus aureus. Soursop leaves were extracted by maceration using ethanol 96%. The extract obtained was then carried out to phytochemical screening. Antibacterial activity test was conducted using disc the Kirby-Bauerdiffusion. This study used 6 concentrations of 500 mg/mL, 400 mg/mL, 300 mg/mL, 200 mg/mL, 100 mg/mL, 80 mg/mL, 60 mg/mL, 40 mg/mL, 20 mg/mL, 10 mg/mL and 1 mg/mL. A positive control used soursop leaf extract of young and old while a negative one used DMSO 10%. Based on phytochemical screening, ethanol extract of soursop leaves contained alkaloids, flavonoids, saponins, tannins, steroids/triterpenoids and glycosides. The antibacterial activity of ethanol extract of leaves of young soursop was higher in inhibitory diameter than the ethanol extract of old soursop leaves. It could be seen that a concentration of 500 mg/mL was equal to 10.87 mm and 8.68 mm; a concentration of 400 mg/mL was equal to 9.15 mm and 7.3 mm; a concentration of 300 mg/mL was equal to 8.34 mm and 6.30 mm; a concentration of 200 mg/mL was equal to 8.23 mm and 7.08 mm; a concentration of 100 mg/mL was equal to 6.32 mm and 6.18 mm, and a concentration of 80 mg/mL did not leave a diameter inhibitory to bacteria Staphylococcus aureus. Young soursop leaf ethanol extract was more effective than the old soursop one against Staphylococcus aureus.

Leptadenia hastata and Anisopus mannii – are perennial plants of family Asclepiadaceae. They are widely distributed in West Africa and are locally used as anti-diabetic agents in Northern Nigeria. This study was conducted to investigate the phytochemical constituent and antibacterial activity of the crude ethanol extract of the Leptadenia hastata and Anisopus mannii against some bacterial isolates from diabetic wound. The phytochemical screening was carried out using standard protocol and antibacterial activity was determined by agar well diffusion method followed by minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) on the plant extract that showed activity. Result of phytochemical screening reveals the present of tannins, phenols, flavonols, saponins, and alkaloids in all the plants extract except in Anisopus mannii where alkaloid is absent. Also, result from antibacterial activity of leptadenia hastata demonstrated inhibition zones ranging from 11.5±0.71 to 20.0±0.00 at various concentrations (8mg/ml and 4mg/ml) against the tested organisms (Citrobacter specie, E.coli, Proteus vulgaris.) with MIC and MBC values ranging from 2mg/ml-8mg/ml. Hence, the ethanol extract of Leptadenia hastata can be considered as new therapeutic agent for the treatment of diabetic wound infection. Further studies need to be carried out to investigate toxicological effect and diabetic wound healing property of the plant.

Objective: In present study different extracts of the leaves of plant Casearia tomentosa was investigated for the phytochemical screening, total phenolic content and various pharmacological activities like antioxidant, antidiabetic, antibacterial.Methods: Leaves of C. tomentosa were successively extracted by soxhlet extraction method using petroleum ether, chloroform, ethyl acetate and ethanol. The preliminary phytochemical investigation of different extracts was carried out according to standard methods. Antioxidant activity evaluated by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and ferric reducing antioxidant potential (FRAP) method. Total phenolic content was evaluated by Folin-ciocalteau method. Antidiabetic activity estimated by α-amylase and α-glucosidase inhibitory assay while antibacterial activity was performed by disk diffusion method.Results: C. tomentosa leaves show the presence of various phytochemicals like alkaloids, flavonoids, carbohydrates, glycosides, protein etc. Results of antioxidant studies revealed that the ethanol extract possessed highest 2, 2-diphenyl-1-picryl-hydrazyl (IC50 31.87±0.65 μg/ml) activity, ferric reducing antioxidant power (43.78±0.65μM/ml, FRAP value=2.30). Among different extracts, ethanol extract shows highest (228.17±0.63 mg gallic acid equivalents (GAE)/gram of dry mass) amount of total phenolic content. The ethyl acetate extract exhibited highest inhibition on α-amylase (IC50 262.08±1.26 μg/ml) and α-glucosidase (IC50 459.25±1.80 μg/ml) enzymes. Results of antibacterial activity revealed that all extracts show inhibition against selected bacterial strains like Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Salmonella typhi.Conclusion: The present study suggests that Casearia tomentosa leaves can be used as a potential source of natural antioxidant and natural antidiabetic, antibacterial agents.
