family cupressaceae is the largest coniferous plant family. essential oils of many species belonging to family cupressaceae are known to have several biological activities specially antimicrobial activity. the essential oils from aerial parts of calocedrus decurrens torr., cupressus sempervirens stricta l. and tetraclinis articulata (vahl) mast. were prepared by hydrodistillation. the chemical ...

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 ...

results the results of the study, using the two methods, showed that all methanol extracts of leaves and fruits of the six species possessed antioxidant activity. the antioxidant activity of the samples was compared with the antioxidant activities of butylatedhydroxytoluene (bht), as a synthetic antioxidant and α-tocopherol as a natural antioxidant. methanol extractions of pinus spp. leaves and...

Chemical compounds containing the tropone structure (2,4,6-cycloheptatrien-1-one), in their molecule, called troponoids, characterized by a seven-membered ring, are distributed in some plants, bacteria and fungi, although they are relatively rare. ß-Thujaplicin (2-hydroxy-4-isopropyl-2,4,6-cycloheptatrien-1-one), also known as hinokitiol, is a natural compound found in several plants of the Cup...

BACKGROUND Respiratory allergy to the pollen of Cupressaceae is becoming more and more common every year in the Mediterranean area. OBJECTIVE The purpose of this study was to see whether the allergenic potency of Cupressus arizonica pollen diminished after a 6-year period (1994-2000). MATERIALS AND METHODS Among the Cupressaceae, we selected the pollen of C arizonica. The mode of sampling i...
