This study is aimed at determining antibacterial activity from ethanol extracts and the most active fraction of cassava leaves against clinical isolates of Staphylococcus epidermidis and Propionibacterium acnes. Research carried out by the experimental method involved determination of plants, extraction with maceration method, fractionation with liquid-liquid extraction, antibacterial activity testing of extracts and fractions by agar diffusion method, determination of most active fraction from the extract, and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) testing of most active fraction by microdilution method. The results showed that ethanol extracts of cassava leaves had antibacterial activity against both bacteria with the most active fraction indicated by ethyl acetate. MIC values of ethyl acetate fraction against S. epidermidis were in the concentration range of 2.5%–5.0% (w/v) and against P. acnes were in the concentration range of 1.25%–2.5% (w/v). The MBC value of ethyl acetate fraction against S. epidermidis was at a concentration of 5% (w/v), while P. acnes was at a concentration of 2.5% (w/v). From the results of this study, it can be concluded that the ethanol extract of cassava leaves (Manihot esculenta Crantz) has antibacterial activity against clinical isolates of Staphylococcus epidermidis as well as on Propionibacterium acnes. The fraction with the best activity from the ethanol extract of cassava leaves to the two test bacteria was shown by ethyl acetate fraction. It is suggested that cassava leaves are possible to be developed into standardized antiacne herbal.

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.

AbstractThree lignan derivatives, (-)-taxiresinol (1), (-)-3′-demethylisolariciresinol-9′-hydroxyisopropylether (2) and (-)-3-demethylisolariciresinol (3), previously isolated from the heartwood of Taxus baccata L. (Taxaceae) were investigated for cytotoxicity against the Oncology Cell Line Panel (breast, colon, ovary, prostate, lung and a normal adult bovine aortic endothelial cell line) as well as for antimicrobial activities. Besides, a chloroform-soluble portion of the ethanol extract from the heartwood of T. baccata was also tested for antimicrobial activities. Compounds 1 - 3 did not demonstrate much cytotoxic potency according to the reference drug etoposide. With the exception of compound 2, the other two lignans (1 and 3) and the chloroform extract were shown to possess antifungal activity, whereas only the chloroform extract exhibited antibacterial activity against Pseudomonas aeruginosa
