Abstract

This research was undertaken mainly to isolate and identify antitermitic substances that may be prospective as wood natural preservative from the bark of Acacia auriculiformis A. Cunn. ex Benth. The woodmeal of the samples were extracted with acetone. The acetone extract was then fractionated into n-hexane soluble fraction, ethyl ether soluble fraction, ethyl acetate soluble fraction, and insoluble fraction. The antifeedant bioassay test was carried out by treating paper discs with extracts at six level of concentration i.e. 0%, 2%, 4%, 6%, 8%, and 10% (w/w). The bioassay test revealed that ethyl ether soluble fraction exhibited high toxicity to subterranean termite Coptotermes curvignathus Holmgren (concentration of 4% has been indicated very strong activity). Keywords: Bioactivity, extractives, Acacia auriculiformis, termites, Coptotermes curvignathus

Abstract

Malaria is still one of the most highly pathogenic diseases, which remains a significant problem for public health. Natural compounds are alternative ways as an antimalarial compound that are applied for the artemisinin combination. The aim of this study was to determine the effect of a combination of S. ligustrina extract and DHP on the differential leukocytes percentages. This study used 100 mice which were divided into five groups. Group A and B were used for the healthy mice and infected-untreated groups, respectively. Group C used as a controlled drug, received 222 mg/kg BW of DHP. Group D received 300 mg/kg BW of aqueous extract of S. ligustrina. Group E received a combination between 111 mg/kg BW of DHP and 200 mg/kg BW of aqueous extract S. ligustrina. The findings demonstrated that DHP and S. ligustrina extract had an impact on neutrophils, lymphocytes, inhibition, and percentages of parasitemia. The findings revealed that treatment groups C, D, and E reduced the percentage of parasitemia. The percentage of neutrophils in treated groups was significantly higher than in group A (P<0.05). The percentage of lymphocytes was lower in the treated groups, while the percentages of eosinophils, monocytes, and basophils did not significantly different (P<0.05). This study found that group D and E had the same effect on the leucocyte profile as group C. Our findings suggest that the aqueous extract of S. ligustrina, as well as the combination treatment with DHP, have the potential to lead to the discovery of new antimalarial medicines.

Abstract

The aim of the study was to analyze the content of pelawan wood extractive substances (Tristaniopsis whiteana (Griff)) and to test it with the fungi Schizophyllum commune Fr and Pleurotus ostreatus. Pelawan heartwood powder was macerated with methanol. Then fractionated in stages with n-hexane, chloroform, ethyl acetate, and butanol. The resulting extract was then tested with S. commune and P. ostreatus fungi. The most active fraction was isolated using column chromatography with a gradient system, the eluent was methanol:chloroform. Sub-fractions were then tested for fungi to determine the most active sub-fractions, and the most active sub-fractions were then analyzed by 1H NMR. The results showed that the extractive content of pelawan wood was most soluble in chloroform. All extract fractions contain potential as anti-fungal. .The chloroform fraction was very active compared to the other fractions. Isolation of the chloroform fraction by column chromatography obtained 8 sub-fractions. All of these sub-fractions were able to inhibit the growth of S.commune and P.ostreatus with IC(50) = 54.55 - 64.69 mg/L and IC(50) = 54.17 - 64.44 mg/L respectively. PL.3 sub-fraction was the most active among the 8 sub-fractions. The results of 1H NMR analysis on the PL.3 subfraction were shown to be Heptanoic Acid compounds.

Abstract

The dissolution of wood lignin in the alkali solution were analyzed for two fast growing species, sengon (Paraserianthes falcataria) dan leda (Eucalyptus deglupta). Wood samples were extracted in 1% sodium hydroxide solution in cold and hot temperatures for 24 and 1 h, respectively. Extractable substances content, permanganate consumption (expressed as assumed lignin content) were analyzed from the filtrates, lignin content and diastereomeric of β-O-4 structure were analyzed from the wood residue after alkali extraction. The extracted substances from both of wood in hot alkali was higher than in cold alkali solution, although the time of cold alkali extraction was much longer that hot alkali extraction. Assumed lignin content in the extract was quite high in both samples which were 34.4-42.9% and 35.5-39.8% including 2,15-2,29% dan 1,04-1,32% of lignin for cold and hot alkali extraction, respectively. The changes in stereo isomeric form, erythro and threo, of β-O-4 structure of lignin in wood residue indicated that partial depolimerization of lignin was takec place during alkali treatment.
