Abstract

The research was conducted to early detection antimicrobial compound producedby Trichoderma harzianum fungi on March 2003. T. harzianum cultured during 7 daysat temperature 25-30°C and shake velocity at 180 rpm. The secondary metaboliteformed isolated and feactionate with wtil asetat and n-butanol, then antibiosis activ-ity tested againts Sclerotium rolfsii Sacc, caused foot rot in pepper plant and pep-per seeds. The results of experiment showed fractinated compound n-butanol indi-cated antimicrobial activity againts S. rolfsii.

Abstract

This Study has tested the antioxidant activity of the extracts from Sida subcordata Span. Testing is done with antioxidant activity using DPPH method provides. Testing of antioxidant activity in vitro with spectrophotometric methods based on absorbance measurements radical DPPH (1,1-diphenylpicrylhydrazyl). All the extracts Showed radical scavenging activity. The ethyl acetate and methanol extracts were the most Appropriate as sources of antioxidant compounds as shown by Reviews their inhibition percentage (IP) values. Percentage inhibitor to extract ethyl acetate and methanol extract respectively 76.16% and 79.28% at a concentration of 1 mg / ml to 0.05 mM DPPH. while the results of the testing activities of antioxidant compounds y pure ethyl acetate extract fraction showed a smaller percentage inhibitor that is equal to 30% at the same concentration. Keyword - Sida subcordata Span, Malvaceae, Antioxidant, Alkaloid

Abstract

The excessive use of antibiotics in the treatment of infections or diseases caused by Staphylococcus aureus is the main cause of antibiotic resistance. Methicillin-resistant S. aureus (MRSA) strains are a serious problem because of their wide distribution in the clinical environment and the living community, so it is necessary to search for antibacterial sources from natural products and traditional medicines such as Kayu racun leaves (Rhinacanthus nasutus). Information regarding the content of the active ingredient and the antibacterial potential of the ethanol extract of Kayu racun leaves is still limited. This study aims to test the phytochemical and antibacterial activity of the ethanol extract of Kayu racun leaves against S. aureus and MRSA bacteria by invitro. The research used an experimental method and was divided into two stages, namely; Phytochemical test of the ethanol extract of Kayu racun leaves using the Thin Layer Chromatography (TLC) method and the antibacterial activity test of the ethanol extract of Kayu racun leaves against S. aureus and MRSA using the paper disc diffusion method. Based on the research results, it can be concluded that the ethanol extract of Kayu racun leaves contains alkaloids, phenols, and flavonoids. The best antibacterial activity was found at a concentration of 100 mg/ml with an inhibition zone diameter of 26.20 mm against S. aureus and 17.90 mm against MRSA.
