Chemical constituents of the essential oil of water and steam distillates of surian heartwood (Toona sinensis) were analyzed by a gas chromatograph-mass spectrometer. Then, the oil was investigated in vitro anticancer bioassay for its possible antioxidant activity by DPPH free radical scavenging and antiproliferative effects by MTT method using Raji lymphoma cancer cell lines (ATCC CCL 86), HeLa cervical cancer cell lines (ATCC CCL2), and Vero normal cell lines (ATCC CCL 81). The essential oil yield from water and steam distillates of surian heartwood was 0.4% (w/w). Thirty-two compounds were identified, that consisted mainly of oxygenated sesquiterpenes (77%). The most representative compounds were spathulenol (21%), isospathulenol (7%), α-cadinol (7%), β-cedrenoxide (6%), and torreyol (5%). The oil showed less effective antioxidant, but the oil had high antiproliferative effects on Raji and HeLa cancer cells with IC50 28 and 134 μg ml-1, respectively when compared to Vero normal cells (IC50 1412 μg ml-1). Our findings suggest that the essential oil of surian heartwood might be considered as a potentially anticancer agent on human cancer cells, especially lymphoma cancer cells.Key words: antioxidant activity, antiproliferative effects, cancer cell lines, essential oil, Toona sinensis

The purpose of this study was to determine the performance of enzymatic hydrolysis on lime pretreated jabon wood (Anthocephalus cadamba Miq). Proceeding hydrolysis process, the morphology and crystallinity changes of pretreated jabon were also examined. In the present study, jabon wood meal was put into digester and then lime was loaded at varied lime loading, i.e. at 0.1, 0.3, and 0.5 g Ca(OH)2 g-1 of dry biomass in 90 ml of water. The slurry was then homogenized and heated in the oil bath at 100, 125 and 150 C for 2, 4 and 6 hours. Enzymatic hydrolysis was performed in accordance to the NREL procedures using a cellulase enzyme. The enzyme loading variation was 10, 20 and 40 FPU g-1 of the substrate. the RSY of pretreated jabon increased up to 9.7 folds from that of its control. The highest RSY was obtained for pretreatment with 0.5 g Ca(OH)2 g-1 dried biomass at 150 °C for 4 hours and hydrolyzed with 40 FPU of cellulase (118 mg equivalent glucose g-1 dry biomass). This yield was comparable with 14.4% More than a third of the lignin and hemicellulose content (45.83 and 65.52%) were degraded by lime pretreatment.Keywords: enzymatic hydrolysis, jabon wood, lime pretreatment, reducing sugar yield

The objectives of this research were to evaluate the extractive substances of heartwood of Kupa wood (Syzygium polycephalum (Mig)) and its potention as bio-active substance to wood destroying fungi i.e., Schizophyllum commune Fr and Pleurotus sp. Successive extraction method was used in this experiment. The heartwood part was then converted into 40 mesh wood flour and followed by extraction using methanol, chloroform, ethyl acetate, n-hexane and buthanol solvents. The extractives obtained were subjected to wood destroying fungi S. commune and Pleurotus sp. The results indicated that the extractive content of S. polychephalum mostly dominated by substance diluted in chloroform (2.87%), followed by ethyl acetate (0.38%), n-hexane (0.33%) and buthanol (0.05%). All the wood extracts of S. polychephalum potentially contain anti-fungal compound to inhibit the growth of S. commune Fr and Pleurotus sp fungi. N-hexane and ethyl acetate extracts of S. polychephalum are the most active extracts. Isolation of ethyl acetate fraction resulted in nine (9) active compounds (G.1-G.9) that could inhibit the growth both S. commune and Pleurotus sp with IC(50) values 49.33-61.71 ppm and 48.84-64.61 ppm, respectively. It was found that G.2 compound of ethyl acetate has anti fungal substance namely 3-O-glucosyl-3’,4’ 5-trihydroxyflavonol.
