Abstract

Gentamicin is one of the antibiotics from the aminoglycoside group used for the treatment of infections. Gentamicin has side effect such as permanent ototoxicity and reversible nephrotoxicity. It was necessary to reduce these effects by combining antibiotic with natural ingredients, one of those is coriander seeds essential oil. Combination therapy is done to reduce the potential side effects, and increase antibacterial efficacy. Antibacterial activity test were conducted to measure the MIC values of gentamicin, essential oils of coriander seeds, and combination of both. Based on the antibacterial activity test, MIC value of gentamicin was 4 µg/mL, coriander seed essential oil was 50 µg/mL and MIC combination of gentamicin and essential oil of coriander seeds were 0.5 µg/mL and 50 µg/mL. The FIC Index value obtained was 1.125 meaning that the combination effect was indifferent. Indifferent combination effect means the use of a combination of coriander seeds essential oil and gentamicin as antibacterial was not better than the single use. Keywords: coriander, essential oil, antibacterial, FIC Index, S. epidermidis

Abstract

Mesoyi oil distilled from the bark of Cryptocarya massoy have been used for traditional treatment of various ethnicities. However, its safety use has not been widely studied. This study aimed to investigate the cytotoxicity of mesoyi oil on vero cells in vitro. The Inhibitory concentration 50% (IC50) of mesoyi oil is evaluated using MTT assay. The results indicated that the mesoyi oil exhibited cytotoxic effects on vero cells with IC50 value of 97.4 μg//mL. This call for further studies to evaluate the cytotoxic activity in vivo. Keywords: cytotoxicity, essential oil, cryptocarya massoy, vero cell

Abstract

The leaves of kenikir are known to have many benefits, one of which can be used as medicine. Kenikir leaves are reported to have antibacterial activity against the bacteria Salmonella typhi (S.typhi). S. typhi is a bacterium that causes typhoid fever. Typhoid fever is still an endemic disease in Asian countries, especially Indonesia. Typhoid fever became the third largest disease in Indonesia in 2010. The study related to the antibacterial activity of kenikir leaf fraction to S. typhi has never been reported. Therefore, it is necessary to conduct research related to the antibacterial activity of extracts and leaf fractions of kenikir to compare their potential against S. typhi. The study was conducted using the disk diffusion method using 5 series of concentrations namely 5%, 10%, 15%, 20%, and 30%. Tests were carried out on methanol extract, hexane, ethyl acetate, and methanol-water fraction. The results showed that highest inhibition zone diameter is 7,75 mm which is reached by methanol extract. The order of the highest inhibiting zone diameter are extract, hexane, ethyl acetate, and methanol-water fraction.

Abstract

Infection is one of the main causes of world health problems, especially in developing countries like Indonesia, one of which is an acute respiratory infection caused by bacteria such as Staphylococcus aureus. Therapeutics are used for the treatment of infections today with antibiotics. However, there are many cases of bacterial resistance to antibiotics that need to develop alternatives derived from plants. One of the plants that have antibacterial activity is the leaves of Waru Gunung (Hibiscus macrophyllus). The purpose of this study was to determine whether the ethanolic extract of H. macrophyllus leaves and their fractions have antibacterial activity against S. aureus. The method used in this antibacterial activity test is the disk diffusion method with a test concentration of 5%, 10%, 15%, 20%, and 25%. The results of this study indicate that all test samples have antibacterial activity except in the water fraction. The highest antibacterial activity was obtained in the ethyl acetate fraction which attracted semipolar compounds in the ethanolic extract of H. macrophyllus leaves. The antibacterial activity of the test samples in sequence from high to low includes ethyl acetate fraction, ethanolic extract, n-hexane fraction, and water fraction.
