Leyland's cypress (xCupressocyparis leylandii) is a putative, spontaneous hybrid between Chamaecyparis nootkatensis and Cupressus macrocarpa. To investigate this putative origin, twenty five Leyland's cypresses were sampled, along with living, putative parents of Ch. nootkatensis and Cup. macrocarpa from gardens in the UK. The DNA was extracted and analyzed by DNA fingerprinting (RAPDs) and Int...

The Seminole Indians of Florida were studied on thek three reservations for blood types, red cell enzymes, serum proteins, physical measurements, and relationships. Both serologic and morphologic factors suggest their close similarity to other Indians and small amount of admixture. The Florida Seminoles are similar to Cherokee “full-bloods” in their absence of Rho and their incidence of 0 and M...

BACKGROUND : Cypress pollen is becoming an increasing cause of respiratory allergy in some regions worldwide. OBJECTIVE : The aim of this study was to determine some of the main allergens implicated in the common cypress (C. sempervirens) pollen allergy. METHODS : Pollen extracts were optimized by using some detergents and chaotropes in order to solubilize both water and non-water soluble p...

The leaf essential oil yields of clementine, cypress, rosemary, tea, and thyme were 0.22, 0.87, 1.46, 1.20, 0.72%, respectively, based on the dry weight plant material. oils contained highest levels oxygenated monoterpenes (60.14-91.70%). Rosemary tea rich in 1,8-cineole (49.98% 57.55%, respectively), they have potent antifungal activity against Alternaria alternata strain (MIC = 5000 μg/ml). T...

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...
