Abstract

An infectious disease caused by bacteria is a disease that often occurs in tropical areas. The used of plant extract is an interesting object of study to overcome these infectious diseases and because of an increase in bacterial resistance to antibiotics. White turmeric rhizome widely used by Indonesia society as an herb which has been used for the treatment of diarrhea and abdominal pain. This study aims to determine the content of secondary metabolities and inhibitory of white turmeric rhizome (Kaempferia rotunda L.) against Streptococcus sobrinus KCCM 11898 and Salmonella typhi ATCC 422 bacteria. The results of phytochemical screening white turmeric rhizome contained compound triterpenoids, steroids, phenolics, and saponins. An antibacterial activity test used agar diffusion method against Streptococcus sobrinus KCCM 11898 and Salmonella typhi ATCC 422 bacteria. Antibacterial activity white turmeric rhizome (Kaempferia rotunda L.) with concentration 1, 2, 4, 8% have an inhibition zone diameter against Streptococcus sobrinus KCCM 11898 bacteria is 10.33, 10.67, 17 and 25.17 mm respectively with the antibacterial strength is strong, meanwhile in Salmonella typhi ATCC 422 bacteria have an inhibition zone diameter was 8, 8.3, 11.83 and 13 mm respectively with the antibacterial strength is intermediate.

Abstract

Meniran (Phyllanthus niruri L.) is one of the herb plants used as traditional medicine, such as toothache medicine and diarrhea medicine. The purposed of this study was to determined the type of secondary metabolites in the ethanol extract of meniran herb and to determined the minimum inhibitory concentration (MIC) value of the ethanol extract of meniran (Phyllanthus niruri L.) to Streptococcus sobrinus KCCM 11898 and Salmonella typhi ATCC 422. The ethanol extract of meniran was tested for phytochemicals. The MIC value of the ethanol extract of meniran herb for the test bacteria was obtained by varying the concentration of the ethanol extract of meniran herbs. Phytochemical test results showed that the ethanol extract of meniran herbs contains alkaloids, phenolics and steroids. The minimum inhibitory concentration value of the ethanol extract of meniran herb at the bacteria Streptococcus sobrinus KCCM 11898 and Salmonella typhi ATCC 422 each was 0.625%. Keywords: Phyllanthus niruri L, minimum inhibitory concentration (MIC), Streptococcus sobrinus KCCM 11898, Salmonella typhi ATCC 422

Abstract

Phytochemical test and toxicity in ethanol extract, ethyl acetate fraction and residual ethanol fraction of ajeran leaves (Bidens pilosa L.) has been done. The method used to determine secondary metabolites is clualitative test and the value of Lethal Concentration (LC50) with the Brine Shrimp Lethality Test (BSLT). Phytochemical test results showed that the ethanol extract and ethyl acetate fraction contained flavonoid, steroid and phenol compound. Residual ethanol fraction contained flavonoid and phenol compound. Toxicity test showed ethanol extract had LC50 value of 862.19 ppm. Ethyl acetate fraction has LC50 value of 8.26 ppm. Residual ethanol fraction had LC50 value of 275.24 ppm. The results of the toxicity test can be concluded that the ethyl acetate fraction very toxic category, ethanol extract and residual ethanol fraction included toxic category. The results that obtained from GC-MS characterization were steroid

Abstract

The test of amylase inhibition activity of the leaves of Melicope lunu-ankenda and bark of Melicope glabra (BI.) T.G. Hartley extracts were done. The objective of this study was to determine in-vitro α-amylase inhibition activity against two samples by DNS method. The result showed that two samples of Melicope lunu-ankenda leaves and bark of Melicope glabra (BI.) TG Hartley displayed the enzyme inhibitory effect with percent inhibitions of 48.71% and 46.36%. Two sample extracts can inhibit amylase. It can be suggested that about sample were potential as antidiabetic agents.
