Abstract
A pilot-scale study was conducted using electrocoagulation technology to treat chlorine dioxide bleaching-stage effluent of a local pulp mill, with the purpose of evaluating the treatment performance. The operating variables were the current density (0 ~ 133.3 A/m(2)) and hydraulic retention time (HRT, 6.5 ~ 16.25 minutes). Water quality indicators investigated were the conductivity, suspended solids (SS), chemical oxygen demand (COD), true color, and hardness. The results showed that electrocoagulation technology can be used to treat D-stage bleaching effluent for water reuse. Under the operating conditions studied, the removal of conductivity and COD always increased with increases in either the current density or HRT. The highest removals obtained at 133.3 A/m(2) and an HRT of 16.25 minutes for conductivity, SS, COD, true color, and hardness were respectively 44.2, 98.5, 75.0, 85.9, and 36.9% with aluminum electrodes. Iron electrodes were not applicable to the D-stage effluent due to formation of dark-colored ferric complexes.

Abstract
This study investigated the chemical composition, in vitro cytotoxic, and antimicrobial activities of the essential oil isolated from the flower of Diospyros discolor from Taiwan. The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Twenty-eight compounds were identified, representing 100% of the oil. The main components identified were (2 Z,6 E)-farnesol (35.0%), α-cadinol (10.9%), ( E)-nerolidol (6.9%), α-humulene (6.0%), τ-cadinol (5.6%), β-caryophyllene (5.3%), and τ-muurolol (5.3%). The oil exhibited cytotoxic activity against human colon, liver, and lung cancer cells. The active compounds were β-caryophyllene, α-humulene, τ-cadinol, τ-muurolol, α-cadinol, and (2 Z,6 E)-farnesol. The antimicrobial activity of the oil was tested by the disc diffusion and micro-broth dilution methods against ten microbial species. The oil exhibited moderate to strong growth suppression against Bacillus cereus, Staphylococcus aureus, S. epidermidis, Escherichia coli, Enterobacter aerogenes, and Candida albicans, with inhibition zones of 40 to 52 mm and MIC values of 31.25–62.5 μg/mL, respectively. For the antimicrobial activities of the oil, the active compounds were determined to be α-cadinol, τ-cadinol, τ-muurolol and (2 Z,6 E)-farnesol.

Abstract
In this study, anti-mildew activities of the essential oils of the leaves, wood, twigs, flowers, and their constituents from Michelia compressa var. formosana were evaluated in vitro against 7 mildew fungi. The main compounds responsible for the anti-mildew activities were isolated and identified. The essential oils from the fresh leaves, wood, twigs, and flowers of M. compressa var. formosana were isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. The essential oil yield from the flowers was the highest, and the oils obtained from the 4 parts of the tree were composed mainly of sesquiterpenoids. The leaf oil consisted primarily of α-cadinol (18.9%) and germacrene D (18.5%); the twig oil's main constituent was α-cadinol (19.1%); the wood oil's major components were α-cadinol (25.7%) and β-eudesmol (20.2%); and the flower oil contained α-cadinol (11.4%). Comparing the anti-mildew activities of the oils suggested that wood oil was the most effective. Further fractionation of the wood oil produced α-cadinol, β-eudesmol, τ-cadinol, and elemol. The 4 compounds exhibit very strong anti-mildew activities, and these in descending order are α-cadinol, elemol, β-eudesmol, and τ-cadinol. For the anti-mildew activities of the wood oil, the active source compounds were determined to be α-cadinol, elemol, β-eudesmol, and τ-cadinol.

Abstract
A novel photobioreactor was developed with a total volume of 30 m(3) which required merely 100 m(3) of land footprint. The bioreactor was capable of utilizing CO(2) in the flue gas of a power plant as the carbon source for the growth of a freshwater alga, Spirulina platensis, mitigating the greenhouse effect caused by the same amount of CO(2) discharge. Results of the study indicated that the photobioreactor was capable of fixing 2,234 kg of CO(2) per annum. Upon deducting the energy consumption of operating the bioreactor unit, the estimated amount of CO(2) to be fixed by a scaled-up reactor would be 74 tons ha(-1)year(-1). In addition, the study prove that protein-free polysaccharides of S. platensis could induce the production of pro-IL-1 and IL-1 proteins through the mediation of ERK, JNK, and p38 MAPKs pathways. As a consequence, immunogenic activities of the macrophage cells were enhanced.

Abstract
In this study, antipathogenic activities of the twig essential oil and its constituents from Chamaecyparis formosensis Matsum were evaluated in vitro against six plant pathogenic fungi. The essential oil from the fresh twigs was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Twenty-five compounds were identified, representing 98.9% of the oil. The main components were β-eudesmol (25.1%), τ-muurolol (21.6%), elemol (15.0%), totarol (14.9%), and α-cadinol (12.4%). The twig oil (500 μg/mL) showed growth inhibitory activity against the phytopathogenic fungi, Fusarium oxysporum, Pestalotiopsis funereal, and Ganoderma austral, with antifungal indices of 92.7%, 71.1%, and 87.7%, respectively. In addition, the oil suppressed totally the growth of Rhizoctonia solani, Colletotrichum gloeosporioides, and Fusarium solani. In order to ascertain the source compounds of these antipathogenic activities, the main components were individually evaluated. τ-Muurolol and α-cadinol exhibited excellent activity against F. oxysporum, R. solani, C. gloeosporioides, and F. solani, with IC50< 50 μg/mL. These compounds also efficiently inhibited the mycelial growths of P. funereal and G. austral. Thus, α-cadinol and τ-muurolol could be considered as potential natural fungicides for controlling fungal pathogens and worth.

Abstract
The hydrodistillated leaf essential oil of Neolitsea parvigemma was analyzed to determine its composition and yield. Sixty-two compounds were identified, the main components being beta-caryophyllene (14.2%), beta-eudesmol (12.9%), alpha-cadinol (10.2%) and tau-cadinol (8.8%). Oxygenated sesquiterpenes (48.9%) and sesquiterpene hydrocarbons (48.8%) were the predominant groups of compounds. The antifungal indexes of the leaf oil against the 7 fungi, Aspergillus clavatus, A. niger, Chaetomium globosum, Cladosporium cladosporioides, Myrothecium verrucaria, Penicillium citrinum and Trichoderma viride, were 100.0, 72.3, 100.0, 100.0, 100.0, 75.8 and 88.6% at a 1 mg/mL concentration, respectively. The oil also exhibited anti-wood-decay-fungi activity against Trametes versicolor, Phaneochaete chrysosporium, Phaeolus schweintizii, and Lenzites sulphureu with MIC values of 50, 50, 25 and 25 microg/mL, respectively. For the antifungal and anti-wood-decay fungal activities of the oil, the active source compounds were determined to be alpha-cadinol, beta-eudesmol and tau-cadinol.

Abstract
Osthole, a coumarin compound, has been reported to exhibit various biological activities; however the cellular mechanism of its immune modulating activity has not yet been fully addressed. In this study we isolated osthole from the seeds of Cnidium monnieri and demonstrated that osthole inhibited TNF-α, NO and COX-2 expression in LPS-stimulated macrophages, without reducing the expression of IL-6. Furthermore, the phosphorylation of p38, JNK1/2, PKC-α and PKC-ε induced by LPS was inhibited by osthole; however, the phosphorylation of ERK1/2 and PKC-δ was not reduced by osthole. Osthole also inhibited NF-κB activation and ROS release in LPS-stimulated macrophages. Our current results indicated that osthole is the major anti-inflammatory ingredient of Cnidium monnieri seed ethanol extract.

Abstract
The leaf and fruit essential oils of Litsea cubeba, extracted by hydrodistillation, were assessed for anticancer activities. A total of 53 and 50 compounds were identified, respectively from the leaf and fruit oils, and their yields were 13.9 ± 0.09% and 4.0 ± 0.03%, v/w, of the oven-dried materials, respectively. The main compound in the leaf oil was 1,8-cineol, and in the fruit oil, citral. The fruit oil, but not that of the leaf, exhibited cytotoxic activity against human lung, liver and oral cancer cells.

Abstract
Much recent research has demonstrated that honokiol, a phenolic compound originally isolated from Magnolia officinalis, has potent anticancer activities; however, the detailed molecular mechanism of its anti-inflammatory activity has not yet been fully addressed. In this study we demonstrated that honokiol inhibited lipopolysaccharide (LPS)-induced tumor necrosis factor-alpha secretion in macrophages, without affecting the activity of the tumor necrosis factor-alpha converting enzyme. At the same time, honokiol not only inhibited nitric oxide expression in LPS-stimulated murine macrophages but also inhibited the LPS-induced phosphorylation of ERK1/2, JNK1/2, and p38. By means of confocal microscope analysis we demonstrated that phosphorylation and membrane translocation of protein kinase C-alpha, as well as NF-kappaB activation, were inhibited by honokiol in LPS-stimulated macrophages. Furthermore, it was found that honokiol neither antagonizes the binding of LPS to cells nor alters the cell surface expression of toll-like receptor 4 and CD14. Our current results have exhaustively described the anti-inflammatory properties of honokiol, which could lead to the possibility of its future pharmaceutical application in the realm of immunomodulation.
