Maritime pine (Pinus pinaster Aiton) and Saharan cypress (Cupressus sempervirens L. var. dupreziana [A. Camus] Silba) are two cone-bearing seed coniferous woody plants. The chemical composition of their essential oils, isolated from needles and leaves by hydrodistillation, was analyzed with gas chromatography (GC) and gas chromatography mass spectrometry (GC/MS). A total of 66 and 28 compounds ...

From the leaves of Microbiota decussata (Cupressaceae) biflavones: cupressuflavone, amentoflavone and 7-O-methylamentoflavone were isolated and identified. The amount of cupressuflavone in Microbiota decussata and xCupressocyparis leylandii (Leyland cypress) (Cupressaceae) was determined by HPLC (1.82% and 0.83%, respectively). The chemical composition of essential oils from bark and leaves of ...

In the course of studies on biological active constituents from woody plants, we previously reported the isolation of many lignan derivatives as neurite outgrowth-promoting compounds from an ethyl acetate soluble fraction of Japanese Cypress (Chamaecyparis obtusa). Further chemical investigation on the residual parts of the ethyl acetate soluble fraction of a methanol extract of Japanese Cypres...

During rough rice storage, changes occur in physicochemical and functional properties of the rice kernel, a process often referred to as aging. This study was conducted to determine how storing rough rice at different moisture contents (MCs) and temperatures over a range of storage durations can impact the nutraceutical content of the rice kernel. Rough rice (‘Cypress’, ‘Cocodrie’, ‘XL6’, ‘XP10...

BACKGROUND Pollens from species of the Cupressaceae family are one of the most important causes of respiratory allergies worldwide. Many patients with pollinosis have specific IgE to both allergens from Japanese cedar and Japanese cypress pollen. We set out to identify T cell epitopes in Cha o 2, the second major allergen of Japanese cypress pollen. METHODS T cell lines (TCL) and T cell clone...

Shifts of functional traits are important because phenotypic responses of species to environmental changes caused by natural and anthropogenic disturbances are fundamental in determining the risk of population extinction. This study tested the effect of forest thinning on the body shape and male genital size of an endemic ground beetle species Carabus masuzoi (Imura and Satô 1989) (Coleoptera,...

Records are given for 15 Scaphisomatini species captured by V-flight intercept traps in Arizona. Baeocera hamata Löbl & Stephan, B. nana Casey and Toxidium gammaroides LeConte recorded the first time from Arizona, arizonensis sp. nov., obscura nov. vintercepta Scaphisoma declivum described as new. dakotanum Fall is synonymized with S. desertorum Casey. The aedeagi of Casey, rufulum LeConte, rub...

Field observations indicate that the distribution of certain forest tree species is modified by periodic flooding of the soil. There appear to be distinct differences between species with respect to the amount of flooding which they will tolerate. Overcup oak, for example, often occurs on areas which are flooded for considerable periods of time during the year, but northern red oak usually occu...

The author is a doctoral student, working under the direction of Prof. Chris Cheeseman in the Civil and Environmental Engineering Department of Imperial College, London. The main subject of his thesis is the transformation of waste-to-energy (WTE) bottom ash to higher value applications. A second subject is the critical analysis of research and development efforts in Europe to advance beneficia...
