Abstract

The aim of this paper is to visualize the alkaloids of Fagraea fragrans fruits therefore the fruits can be scientifically used as herb traditional medicines and phytocosmetics.  Three alkaloids have successfully been identified from those Fagraea fragrans fruits, Loganiaceae. They are gentialutine, gentianine, and isaindigotone. The alkaloids were alternately explored by means of ether and 2% H2SO4 extractions. The sulphuric acid phase was naturalized with ammonium chloride and then extracted with ethyl acetate. The residue were then subjected to silica gel G60 (70-230 mesh) column chromatography and eluted with 40% ethyl acetate in n-hexane. The LC-MS spectral of alkaloids gave the protonated molecular ion peaks at m/z (r.t. minute) = 150.08 (1.39), 176.06 (4.80), and 351.37 (5.24) respectively.

Abstract

The effect of Lactobacillus acidophilus combined with and without Chito-Oligosaccharide (COS) on the growth of Escherichia coli and Staphylococcus aureus had been studied. The antibacterial activity of L. acidophilus before and after combination with COS 0.2% was tested on bacteria of E. coli and S. aureus with well-diffusion method. Incubation time was carried out in 44, 46, 48, 50, and 52 hours. Organic acids produced by L. acidophilus bacteria was measured by HPLC. The result showed that COS 0.2% can inhibit the growth of E. coli and S. aureus 37.2 mm2 and 52 mm2 respectively. Combination of L. acidophilus and COS 0.2% gave inhibition zone larger than L. acidophilus without COS 0.2%. Incubation time within 48 hours of L. acidophilus combined with COS 0.2% produced the largest inhibition zone against E. coli and S. aureus 367.92 mm2 and 343.99 mm2 respectively. Optical density measurement resulted in higher value for combination one but concentration of organic acid produced was lower compare to L. acidophilus without COS 0.2%.Keywords: COS, L. acidophilus, Organic acid, antibacterial.

Abstract

Antibiotics are commonly used in poultry ration, and afterward these drug residues may persist in foods. There is an alternative source of antibiotics in poultry rations, one of which is using probiotics. Probiotics are living microorganisms capable of reaching the gastrointestinal tract and benefiting health, leaving no residue in the body. Probiotics can be originated from bacteria such as lactic acid bacteria (LAB) which produced lactic acid and antimicrobial components. LAB must be able to live in the digestive system with various pH condition. pH resistance testing of LAB was performed by introducing diluted bacteria into several buffer solutions with different pH and a predetermined incubation time, then was grown in MRS agar medium. This study was conducted to determine the resistance of LAB isolates as probiotics from silage forage swamp at different pH distributed in vitro digestant. The design used was a complete randomized design consist of 3 treatments and 3 replications. The treatments were using isolate of Kumpai Tembaga silage (P1), isolate of 50% Kumpai Tembaga silage and 50% Kemon Air silage (P2), and isolate of Kemon Air silage (P3). The results showed that all isolates used were lactic acid bacteria, and the treatment significantly affected the value of LAB resistance test against low pH and high pH. Isolate from Kumpai Tembaga silage (P1) is a lactic acid bacterium with higher ability to survive in pH of in vitro digestive system.
