Publisher : Masyarakat Peneliti Kayu Indonesia

The objective of this study was to evaluate the antitermitic activities of young teak wood through wood extracts and wood blocks samples method. Correlation between extractive content and its antitermitic properties was also studied. The disc samples from the bottom part of the five 8 years old and four 22 years old trees were sawn and samples from outer sapwood, inner sapwood, outer heartwood, and inner heartwood were prepared. Extractive contents were determined through secluded cold extraction of the wood meal using n-hexane, ethyl acetate (EtOAc) and methanol (MeOH). Force-feeding method using Reticultermes speratus Kolbe termites was used for termite resistance test. A significant interaction between tree age and radial direction factors existed with regards to the n-hexane and EtOAc extractive content. The tree age factor did not affect the mass loss levels in the extract samples. The most susceptible to termites was the sapwood of the 8 years old trees. The n-hexane and ethyl acetate extracts of the inner and outer heartwood significantly influenced the mortality rate, but in contrary to that of tree age. The EtOAc extracts of the outer heartwood was the most active antitermite. The extractive content of heartwood did not correlate to antitermite properties.Key words: antitermitic activities, community forest, extractive, Reticultermes speratus, Tectona grandis

The objective of this research is to find out the extractive composition of mangium wood. A total of 25 mangium trees (24-years) from 5 provenances (Sidei Papua, West of Morehead, Daintree, Ellerbeck, Red Cardwell, and El Arish) were investigated. The extractive contents were determined by successive soxhlet extraction in two solvents (n-hexane and methanol). The results showed that the effect of provenance factor is not significant by analysis of variance. The range of n-hexane extracts were 1-6% which the highest value was obtained in the heartwood whereas methanol extracts ranged from 3-18% as the highest value was measured in the bark. In the n-hexane extracts based, neutral fractions dominated (80-95%) the composition the sapwood and heartwood. After saponification, the similar tendency was also observed which the unsaponifiables (60-80%) composed the most part in the neutral fraction of sapwood and heartwood. In the methanol extracts based, residue fractions (55-65%) composed the most part in the bark while dichloromethane fractions were comparatively high (30-41%) in the sapwood parts. In the heartwood, buthanol and residue fractions dominated (15-77%) in considerable varied patterns. Differences due to provenance factor was also observed, both in the n-hexane and methanol extract fractions.Key words: Acacia mangium, extractives, provenance, radial direction

Analysis of the chemical components and anti-oxidative properties of copals were conducted. Copal samples were procured from 6 trees of Agathis borneensis stand established in Banyumas Timur Forest Management Unit. SNI 7634:2011 was referred in chemical analysis of the samples. The copals were dissolved in toluene and ethanol, consecutively. Neutral and acidic fractions were obtained by fractionation of toluene soluble extracts. Total phenolic content of ethanol soluble extracts were determined by Folin-Ciolcateu method. Copal components were detected by GC-MS analysis and anti-oxidative properties were examined by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) test. Dirt content, ash content, and acid number were found in the range of 6.25-22.63%, 0.05-0.16%, and 190-378, respectively. Solubility in toluene was of 19-46% and solubility in ethanol was of 53-81% based on extract weights. Neutral and acidic fractions based on toluene extract were in the range of 20-44% and 56-80%, respectively. The components of copal were assigned as resin acid (agatholic acid), neutral diterpene derivates (agathadiol, labdanenone, labdadienedioat), and alcohol monoterpene. Total phenolic content was in the range of 12-22 mg g-1 extract equivalent to gallic acid . Anti-oxidative values of the presently investigated copal were comparatively low, regardless of the copals were indicated to contain phenolic compoundsKeywords: Agathis borneensis, antioxidative properties, copals, extractives, resin

Antitermite activities of leaf hexane extract of cat whiskers (Orthosiphon sp.) leaves, ethyl acetate, and ethanol- toluene extracts of pepaya (Carica sp.) leaves were investigated in several concentrations (1, 5, 10, and 15%, weight based) that be impregnated to filter papers againts the dry-wood termites Cryptotermes sp. After impregnation, filter papers were dried into oven at 60 °C for 3 hours, then were tested to termites for 4 weeks. The results showed that treatment concentration could obtain the highest termites mortality level, no weight loss and the lowest damage level. Ethyl acetate extract of papaya leaves exhibited the highest termites mortality (91.2%) at concentration of 10%. This concentration also showed the lowest weight loss (0%) and the highest antifeedant activity (antifeedant coefficient of 100%). Ethyl acetate extract of papaya leaves exhibited the lowest of LC50 value (7844.20 μg ml-1 ). Antitermitic activity showed a trend more repellent than toxic. Fatty acid such as hexadecanoic acid, linolenic acid, octadecanoic acid and steroid compounds that detected by GC-MS were estimated to play a role as antitermite agents. Thus, the application of ethyl acetate extract of papaya leaves at concentration of 10% was recommended to the next experiment by using solid wood impregnation.

Sampling by increment borer along with wood extraction by cold soaking would be useful for large sample size and if the destructive sampling is undesirable. This work aimed to evaluate the reliability of cold extraction by methanol and acetone to extract the quinone compounds of teak heartwood compared to the conventional soxhlet extraction by ethanol-benzene. Another purpose of this work was to find out the intra-tree variability of quinone compound around the outer heartwood parts (8 angles, 16 points). On the basis of the yield of ethanol-benzene extracts in 6 trees, cold extraction could remove the extracts of 37-66% by methanol and 23-61% by acetone. By correlaton analysis, considerable degree of correlations (r>0.9) were calculated between soxhlet and cold extraction in the contents of deoxylapachol, lapachol, tectoquinone. With regard to intra-tree variation quinones, wide level ranges were observed in all compounds by judging the coefficient of variation, except for tectol. Therefore, it is suggested that the sampling in the tangential direction in a single tree should be taken at 3 points separated by at least 90 degrees to avoid the bias in the individual components. The variation of quinone total amounts, however, showed comparatively low (18%) of coefficient of variation.Keywords: cold extraction, extractives, incrrement borer, quinone, Tectona grandis

Publisher : Masyarakat Peneliti Kayu Indonesia

Teak (Tectona grandis L.f.) wood has gained its high reputation for natural durability, weather resistance, and appearance. The heartwood quality of 15, 25, and 72-year-old teak trees from forest plantation was assessed in relation to chemical and colour properties. With tree age, an increasing tendency was found in the ethanol-benzene and water soluble extractive contents, whereas a decreasing tendency was observed in the pH value. Furthermore, from the ethanol-benzene components, the contents of tectoquinone, squalene, and total quinone increased with age. With regard to the colour properties, the brightness (L*), yellowness (b*), hue (h), and chroma (C*) levels tended to decrease while the redness (a*) level fluctuated with tree age

The aim of this study was to find out the effect of Ethephon, an ethylene releasing compound, in a combination with sulfuric acid resin production Pinus merkusii. The tested stimulants were ETRAT; SR4; 20% sulfuric acid; 20% sulfuric acid - Ethephon 2%; 3.3% sulfuric acid – 4.1% Ethephon; and sulfuric acid – 8.3% Ethephon. Trees without stimulant spraying were the controls. The results showed that for daily production, the first-day observation gave the highest value but decreased drastically after second-day observation in a varied degree depent on the stimulants. On the basis of accumulated production, the addition of Ethephon in a high or low level of sulfuric acid concentration exhibited significantly higher resin production compared to that of ETRAT; SR4; and 20% sulfuric acid stimulants as well as control trees. It increased resin production by 98.0-150.6% compared to control trees in class age of VII and increased by 140.9-227.1% in class age of IV stands. Moderate significant correlations (r=0.65) were observed between the values of resin production and tree diameter (controls) as well as between the values of resin production and tree diameter of trees treated by sulfuric acid stimulants (r=0.65-0.82).

Publisher : Masyarakat Peneliti Kayu Indonesia

Chemical properties of 32 teak woods representing 3 different diameter classes (slow, medium, and fast growth-rate) at the same age class were evaluated. The content of cell wall component and extractives of outer heartwood part were determinated according to ASTM and TAPPI standard. The extractives components of wood were characterized by Gas-Chromatography Mass-Spectrometry (GC-MS). By analysis of variance, there was not significant difference among the growth-rate in the content of holocellulose, α-cellulose, pentosan, Klason lignin, acid soluble lignin, ash, and hot-water soluble extractives. The diameter class significantly affected the ethanol-benzene soluble extractives which faster growth-rate trees tend to have higher values than those of slower growth-rate trees. However, based on GC and GC-MS, there was not significant differences in the levels of major components of ethanol-benzene extracts both of quinones (deoxylapachol and its isomer, lapachol, tectoquinone, and tectol) and non-quinones (palmitic acid and squalene).

Strychnos lucida R.Br. is a medicinal plant believed to treat various diseases. The study aimed to identify the phytochemical compounds, total phenolic content (TPC), antioxidant, and antibacterial activity of the root, seed, stem, and leaf of S. lucida. Antioxidant activity was examined using the DPPH method in the methanol extract. The extract of four parts of S. lucida was tested against three bacteria (Bacillus subtilis Inacc-B334, Staphylococcus aureus Inacc-B4, and Escherichia coli Inacc-B5) using the disk diffusion method. The results showed that alkaloids and tannins were detected in all parts of the plant. The highest TPC was shown in root (6%) and the lowest TPC was found in seed extract (4.67%). The antioxidant activity test presented the value of IC50 of the methanol extract of root, seed, stem, and leaf as 129.65 µg/ml, 255.04 µg/ml, 145.28 µg/ml, and 112.96 µg/ml, respectively. Furthermore, the stem showed antibacterial activity by inhibiting the growth of B. subtilis and S. aureus in a concentration of 10% of the sample extract (v/v). Leaf extract has activity against only S. aureus growth in different concentrations (2.5, 5, 10%), while all bacteria were resistant to root and seed extracts. The stem extract showed the highest antioxidant and antibacterial activity compared to other parts.
