Abstract

The objectives of this research were to evaluate the extractive substances of heartwood of palepek baringin wood (Shorea leavis Ridl) as a bio-active substance to wood destroying fungi i.e. Schizophyllum commune Fr and Pleurotus ostreatus. The 40 mesh of heartwood meals was extracted by methanol, chloroform, ethyl acetate, n-hexane and buthanol. The extractives obtained were subjected to wood destroying fungi S. commune and P. ostreatus, and preservative containing copper, chrome and boron (CCB) was used for comparison. The extractive of palepek baringin wood was dominated by ethylacetate fraction (3.54%), followed by chloroform and butanol fraction 1.73% and n-hexane (0.09%). All fractions have an antifungal activity to inhibit the growth of S. commune and P. ostreatus. Concentration of 50 ppm butanol fraction inhibited the growth of S. commune, and concentration of 250 ppm chloroform fraction inhited the growth of Pleurotus sp. Preservative of CCB 100 ppm inhibited the growth of S. commune and P. ostreatus by 43%. Butanol fraction contained 16 active compounds (PB.1-PB.16) that could inhibit the growth both of S. commune and P. ostreatus with IC50 54.29-64.32 and 48.40-65.86 ppm, respectively. Based on mass spectrometry (LC-MS) and 1HNMR analysis, the compound of PB.1.1 which has anti-fungal activity was 2,3-dihydroxyoctadecanoic acid.Key words: 2,3-dihydroxyoctadecanoic acid, antifungal, Pleurotus ostreatus, Schyzophlum commune, Shorea leavis

Abstract

The aims of this research were to determine the yield extracts from continuous extraction of suren heatwood (Toona sureni) in n-hexane, ethyl acetate and methanol solvents, to evaluate this extracts using in vitro anticancer tests (antioxidant, brine shrimp lethality test /BSLT, antiproliferative effects to HeLa servical cancer cell lines, Raji limphoma cancer cell lines, and Vero normal cell lines), and to analyze the best extract based on the anticancer activities. This experiment showed that the yield of methanolic, ethyl acetate, and n-hexane extracts were 0.43%, 0.25%, and 0.18% respectively. The methanolic and ethyl acetate extracts had the high antioxidant activities with EC50 51 and 68 μg ml-1 respectively. Based on BSLT, the ethyl acetate extract was the most active extract (LC50 40 μg ml-1), it followed by the methanolic extract (LC50 116 68 μg ml-1 ), and the n-hexane extract (LC50 161 68 μg ml-1). Further testing showed that the ethyl acetate extract had high antiproliferative effects to Raji (IC50 31 μg ml-1) and HeLa (IC50 65 μg ml-1), but it was more secure against Vero cell lines (IC50 105 μg ml-1). Whereas compounds such as catechol, linalool, and sitosterol contributed to the high anticancer activities of this ethyl acetate extract.Key words: anticancer activity, HeLa cell lines, Raji cell lines, Toona sureni, Vero cell lines

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

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.
