Volatile constituents of Pinus roxburghii from Nepal
BACKGROUND Pinus roxburghii Sarg. Is one of 3 species of pine found in Nepal, the oil of which is traditionally used to treat cuts, wounds, boils, and blisters. OBJECTIVE To obtain, analyze, and examine the anti-microbial and cytotoxic activities of the essential oils of P. roxburghii. MATERIALS AND METHODS Three plant parts (cone, needle, and bark) of Pinus roxburghii were collected in Bir...
متن کاملEvaluation of Nonlinear Height-Diameter Models of Two Important Species of Turkish Pine (Pinus brutia) and Mediterranean Cypress (Cupressus sempervirens var. horizontalis), in the Planted Forests
Knowledge about the relationship between tree height (H) and diameter at breast height (D) is crucial for forest planning, monitoring, biomass estimation, and forest stands dynamics description. In this study, 20 different height-diameter models were evaluated to estimate accurately the height of the trees of Pinus brutia and Cupressus sempervirens var. horizontalis species in Arabdagh region (...
متن کاملEvaluating of Different Height-Diameter Nonlinear Models for Hornbeam in Uneven-Aged Stands (Case Study: Golestan Rezaeian Forest)
Projection of stand development over time relies on accurate height-diameter functions. In this study, we evaluated the capability of 43 nonlinear models to estimate hornbeam heights in a portion Rezaeian experimental forest in Gorgan, Golestan province. We applied a systematic random sampling method to collect field data within a 150×200 meter network (3.33% intensity). It resulted in 200 circ...
متن کاملPharmacognosy of Pinus roxburghii: A Review
Pinus roxburghii Sarg. (syn. Pinus longifolia Roxb.) (Pinaceae), found in the Himalayan region, furnishes an oleoresin which is used as insecticides, disinfectants and liver disorders. P. roxburghii are reported to have wound healing, cytotoxic, antibacterial, antifungal and spasmolytic actions. The plant also shows beneficial effects in the treatment of cough, ulceration and genito-urinary dis...
متن کاملAnalgesic and Anti-Inflammatory Activity of Pinus roxburghii Sarg.
The Chir Pine, Pinus roxburghii, named after William Roxburgh, is a pine native to the Himalaya. Pinus roxburghii Sarg. (Pinaceae) is traditionally used for several medicinal purposes in India. As the oil of the plant is extensively used in number of herbal preparation for curing inflammatory disorders, the present study was undertaken to assess analgesic and anti-inflammatory activities of its...
