Abstract

Zingiber cassumunar Roxb. (Bangle), Guazuma ulmifolia Lamk. (Jati belanda), and Murraya paniculata (Kemuning) have been used as slimming agents in jamu. A few researches have performed studies on their potency as antiobesity. The aim of this research was to investigate the potency of Z. cassumunar rhizome, G. ulmifolia, and M. paniculata leaf extracts as antiobesity agent based on in vitro inhibition activity of the extracts on pancreatic lipase activity. In this research, water content determination, phytochemical assay, toxicity assay and in vitro assay of inhibition activity on pancreatic lipase were performed toward single and mixture extracts of Z. cassumunar, G. ulmifolia, and M. paniculata resulted by water, ethanol, and saponin extractions. The results indicated that 100 ppm of ethanol extraction of Z. cassumunar had highest inhibition effect on the activity of pancreatic lipase (29.17%), followed by 100 ppm of water extraction of M. paniculata  (25.66%), 60 ppm of ethanol extraction of G. ulmifolia leaves (25.13%) and ethanol extraction mixture of Z. cassumunar, G. ulmifolia, and M. paniculata  leaves with ratio of 25:25:25 (21.58%). These inhibition effects were higher than inhibitory effect of 100 ppm of Xenical®/orlistat as the positive control, with the inhibition value of 17.53%. Saponin crude extracts had lower inhibitory effect than the other extractions. It was suggested that ethanol extraction of Z. cassumunar, and G. ulmifolia and water extraction of M. paniculata had potency as antiobesity agent

Abstract

Most of the alcohol analytical methods are robust and instrumentally expensive. An alternative of ethanol biosensor based on selected biofilm forming Acetobacter aceti bacteria producing alcohol oxidase was constructed on a screen-printed carbon electrode. The enzyme specifically oxidizes the ethanol and generate electrical current that then electrochemically detected and measured by cyclic voltammetry method. A scanning electron microscopic analysis indicated that the biofilm was formed firmly in the electrode. This constructed biosensor reached its optimum at biofilm formed by bacteria of 1.33 × 1010 cells/ml, temperature of 27°C, and pH 7. The enzyme kinetic had KM and Vmax AOX values of 3.5 mm and 125 μA respectively. The biosensor had detection and quantization limit of 0.003 and 0.009%, respectively, and a sensitivity of 57.29 μA (%)-1. A linearity and relative deviation value were revealed at 0.993 and 1.95% respectively. The biosensor was relatively specific and had no interferences with methanol, sodium chloride and citric acid as the common interferences of ethanol compounds. Furthermore, the biosensor had been stably for at least 55 days. Therefore, this constructed biosensor should be developed into a prototype for a practical effective analysis.

Abstract

Monitoring of water quality from the presence of polyaromatic hydrocarbon (PAHs) compounds and its derivates are important for keeping the healthy aquatic environment. Some of those derivates are phenol and several related compounds sharing simmilar structures. This reseach aimed for the detection of those phenol and several similar compounds monitoring due to PAHs degradation. Three identified bacterial isolates of Pseudomonas aeruginosa, Staphylococcus sciuri, and Bacillus amyloliquifaciens were selected based on their phenol degradation characters. On physiological properties all three isolates were observed to degrade several hydrophobic substances such as for naphthalene and anthracene. Yet, genetic analysis indicated that the phenolic degradating oxygenase gene was detected only in the P. aeruginosa and S. sciuri. Applying those isolates for biofilm as biosensor showed a sufficient analytical performance such as their limit of detection between 0.1-0.5 μM.

Abstract

This study aimed to evaluate the potential of marine fungus Purpureocillium lilacinum isolated from an Indonesian marine sponge Stylissa sp. as an anti-obesity agent through pancreatic lipase inhibition assay. The fungus was identified as P. lilacinum through morphological and molecular characteristics. The fungal extract’s inhibition activity and kinetics were evaluated using spectrophotometry and Lineweaver-Burk plots. Ethyl acetate and butanol were used for extraction. Both extracts showed pancreatic lipase inhibition in a concentration-dependent manner. Both crude extracts were then fractionated once. All fractionated extracts showed inhibitory activity above 50%, with the highest activity found in fraction 5 of ethyl acetate at 93.41% inhibition. The best fractionated extract had an IC50value of 220.60 µg.mL-1. The most active fraction of P. lilacinum had a competitive-type inhibitor behavior as shown by the value of Vmax not significantly changing from 388.80 to 382.62 mM pNP.min-1, and the Michaelis-Menten constant (KM) increased from 2.02 to 5.47 mM in the presence of 500 µg.mL-1 fractionated extract. Metabolite identification with LC-MS/MS QTOF suggested that galangin, kaempferol, and quercetin were responsible for the observed lipase inhibition.

Abstract

The Spatholobus littoralis Hassk. (S. littoralis Hassk.) is a native plant in Indonesia and has been widely used in traditional Dayaknese medicine for non-communicable degenerative diseases. One of these illnesses, known as gout, is caused by excessive uric acid in the blood, which is the catalytic byproduct of a xanthine oxidase (XO) enzyme. In this work, we investigated the inhibition kinetics of XO and identified bioactive compounds from the stem extract fractions of S. littoralis Hassk. using liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). Fractionation was carried out to obtain n-hexane, dichloromethane, and 1-butanol fractions from the water and 70% ethanol extracts. Fraction of 1-butanol from 70% ethanol and water extract displayed potent inhibitors of XO with IC50 value 116.91±3.51 and 137.15±5.00 mg/L, respectively. Lineweaver-Burk plot analysis showed that the 1-butanol fraction from the two extracts inhibited XO competitively. The 1-butanol fraction from the two extracts has been further identified as a bioactive fraction. The majority of the compounds in the two active fractions were phenolics. These findings revealed that the 1-butanol fraction from the two extracts is promising as an antigout treatment in the future.

Abstract

Sponge-associated marine fungi are potential source for secondary metabolite compounds. The aim of this research was to investigate sponge-associated marine fungus as secondary metabolite producers against Escherichia coli. The fungus was isolated from Indonesian marine sponge Stylissa sp. and identified as Aspergillus hortai through a combination of morphological and molecular characteristics of ITS DNA and β-tubulin genes. The fungus was tested against E. coli using fungal broth and mycelial extracts. The optimized condition was achieved by fungal broth grown in corn meal broth at 6-days of shaking incubation. Fungal extract was produced using three liters of filtered fungal broth and extracted in ethyl acetate. The antibiotic activity of the extract is vulnerable to 45°C heat and basic or acidic conditions. Therefore, the extraction was done at pH 7 with evaporation at 40°C. The extract shows 7 major bands on TLC with 1 band shows activity against E. coli (Rf 0.81) on bioautogram. The band was observed as a yellow color and turned black in short-wave UV and did not show any fluorescence in long-wave UV. This research shows that sponge-associated marine fungi obtained from Indonesia has the potential as anti E. coli worth to be explored for searching new antibiotics.
