Abstract

Rubus fraxinifolius can be founded in the mountainous regions of West Java. Previous studies have shown that this plant has potent antioxidant activity. The content of polyphenol compounds in this species contributes substantially to antioxidant activity, and the extraction method will affect the content of the compound. In this study an evaluation of the extraction method effect on leaves, young fruits and stems of R. fraxinifolius on the content of polyphenols and their antioxidant activity, have been done. Method: The leaves, fruits, and stems of R. fraxinifolius were extracted by maceration, reflux, and soxhlet using methanol as a solvent. Each extract was determined the total polyphenol content using Folin-Ciocalteu reagent and antioxidant activity test using DPPH reduction method. Result: The highest extract yield was R. fraxinifolius leaf reflux extract (30.20%). The highest total polyphenol content was given by the Soxhlet extract of leaf R. fraxinifolius (48.79 mg GAE / g extract). The highest antioxidant activity was leaf Soxhlet extract of R. fraxinifolius (98.29% at 100 ppm). Conclusion: From this study it was shown that the methanol extract of R. fraxinifolius leaves extracted by Soxhlet gave the highest polyphenol content and antioxidant activity.

Abstract

New potential antifungal antibiotics UK-2A, B, C and D were elucidated as nine membered dilactone derivatives, isolated from mycelial cake of an actinomycete strain 517-02. In the continuation of a screening program in order to discover other useful bioactive metabolites from the same microbial sources, a novel UK-3 and two known compounds of UK-4 and UK-5 have been isolated.The molecular structure of UK-3 was very similar to UK-2A, except thai UK-3 did not have any methoxy group (-OCH3) on pyridine at ('-4'. UK-4 and UK-5 were identified as kown compounds of isocoumarine. These structures were elucidated based on their spectral and chemical evidence.Biological activity assay, demonstrated that UK-3 was active as against to Saccharomyces cerevisiae, Aspergillus niger dan Neurosporo sitophila and inhibited growth of cancer cell, P-388, B-16, KB and COLO-201.

Abstract

A research was carried out to isolate the constituents of Smilax cordiforia trunk bark. It is a famous medicinal plant in Mexico, used as weight control. The isolation methods were carried out by maceration in ether, and remaceration in methanol, and then both of crude extracts were purified by using combined chromatography technique. In the purification and identitification of the ether extract two compounds as steroid saponins, 3-B-O -B-D-glucopyranosyl sitosterol (1) and a mixture of 6-O-palmitoyl-glucopiranosil sitosterot, 6-0stearylglucopyranosyl sitosterol and 6-0arachidoyl-glucopyranosyl sitosterol (2) were obtained, which also have been isolated from other medicinal plants. Isolation from methanol extract resulted in four known substance of phenolic derivatives, identified as afilbin (3) isoastilbin (4), engelitin (5). and chlorogenic acid (C). engelitin demonstrated antifungal activity, astilbin and chlorogenic acid showed antifungal, antibacterial, and antiviral activities. Chlorogenic acid also exhibited antimutagenic, antitumour and antioxcidant activities. Their molecular structures were detemined on the basis of combied spectroscopic methods including two dimensional NMR (2D NMR).

Abstract

Allicin compound (2-propene-1- sulphinothioat acid S-2-propenyl ester) is known to have potential as antiplasmodium in vitro. However, the inhibitory activity mechanism of Allicin to plasmodium is still unknown. In this research, we determined the inhibitory activity of Allicin in silico. Identification of physicochemical properties of Allicin compound and two Allicin derivatives, Alc1, Alc2 and Ac2Alc3 were also conducted.. Furthermore, analysis of drug-likeness and adsorption-distribution-metabolism-excretion (ADME) were carried out on the Allicin compound and its derivatives to find the potential of these compounds as drug candidates. In determining the specific interaction, we utilized molecular docking analysis between Allicin and its derivatives against a protein target Cysteine Protease (SP). Molecular  docking results showed that Allicin derivative, Alc2 (S-prop-2-en-1-yl 3-methylbut-2-ene-1-sulfinothioate, C10H18OS2) has better potential as inhibitors than Allicin, based on the lower bond energies and the inhibition constants, thus Alc2 can be used as an antiplasmodium agent candidate.Keywords: Allicin, Allicin derivatives, drug likeness, ADME, molecular docking

Abstract

Lipases are known as glycerol ester hydrolases that catalyze the hydrolysis of triglycerides into free fatty acids and glycerol. Lipases are found in human, animal, plant, and microorganisms. The aim of this research is to identify lipase producers and characterize bacterial lipase from West Java plateau soil. Plateau soil bacteria samples were isolated on lipase screening medium containing Rhodamine B. Olive oil was used as a substrate in screening and production medium bacterial lipases. From 16 bacterial isolate of lipase producers, 14 were identified as Bacillus sp. and the others were identified as Pseudomonas alcaligenes. All isolates were taken into production step to determine their lipase activities. Moreover, top 3 lipase activities out of 16 lipase activities were chosen to find the optimum pH and temperature. Both characterizations showed pH optimum and temperature optimum from each lipase. These optimum condition were used in heat stability characterization for each lipase samples. The result showed that lipase from isolate COK 2 in optimum pH 4 and temperature 50oC was the most stable lipase due to this sample has good and stable activity for 1 to 5 hours incubation time. Lipase sample from isolate COK 2 has good efficiency for lipase productivity in acid condition and high temperature. Results of this investigation could encourage utilization of these activity enhancers for various industrial applications.

Abstract

Shrimp shells as side product of frozen shrimp industry isnot yet used in pharmaceutical or chemical industries. Shrimpshells has a chemical constituent called chitin, calcium carbonateand protein as main compounds. By decalcination in dilute aqueosHCl solution (1-2 N) and deproteination ill dilute aqueos NaOHsolution (3-4 Nj gives a chitin. Deacetylation of chitin in theexcess of aqueous 50 % NaOH solution produces chitosan. Inthe preleminary experiment indicated that water (< 10%) andash (< 2%) content of chit os an same as standard. Based on theexperiment result the optimum condition was obtained as 1N HCIsolution (1: 10), 3N NaOH solution (1:6) and 50 % NaOH solution(1: 5) resulted 12,61 % chitosan with deacetylation degree valueabout 70 % with FT1R methode. Hydrolysis of chitin or chitosanin excess HCl gives glucosamine about 17 %, it's a mixture of aand B-glucosa11line. Glucoseamine is identified using 1H and13C NMR spectrum.
