We examined multivariate evolution of 20 leaf terpenoids in the invasive plant Melaleuca quinquenervia in a common garden experiment. Although most compounds, including 1,8-Cineole and Viridiflorol, were reduced in home compared with invaded range genotypes, consistent with an evolutionary decrease in defense, one compound (E-Nerolidol) was greater in invaded than home range genotypes. Nerolido...

Valeriana jatamansi Jones is an important medicinal plant that grows wild in Himachal Pradesh, India. Molecular and biochemical diversity among 13 natural populations from Himachal Pradesh was assessed using RAPD and GC-MS to know the extent of existing variation. A total of seven genetically diverse groups have been identified based on RAPD analysis which corroborated well with the analysis ba...

the essential oil of the root of heracleum persicum (apiaceae) was analyzed by capillary gc and gc /ms. the major constituents were identified as viridiflorol (23.05 %), elemol (3.63 %), b-maliene (3.07 %), spathulenol (3.34 %) and 2-tetradecanol (3.38 %).

AIM The purpose of this study was to evaluate how increasing NaCl salinity in the medium can affects the essential oils (EOs) composition and phenolic diterpene content and yield in leaves of Salvia officinalis L. The protective role of such compounds against NaCl stress was also argued with regard to some physiological characteristics of the plant (water and ionic relations as well as the leaf...

Introduction: Melaleuca is a Myrtaceous genus of flowering plants about 290 species, distributed throughout Indonesia, Papua New Guinea, Australia, and Caledonia. Objective: To identify the chemical composition essential oils from leaves, twigs fruits M. quinquenervia cultivated as ornamental in Costa Rica. Methods: The were obtained through steam distillation process Clevenger type apparatus. ...

Background: Essential oils extracted from plants have been widely used in antimicrobial activity, particularly the Callistemon viminalis, with a high number of essential extracted. Objectives: To identify chemical composition oil derived viminalis and evaluates its activity against selected bacterial fungal strains. Subjects methods: During study, different on some bacteria (Escherichia coli, P...

Valeriana jatamansi Jones germplasm collected from sub-temperate Himalayan region of Uttarakhand and North-East state of Meghalaya, India was evaluated under identical conditions at National Bureau of Plant Genetic Resources, Bhowali, India, to study germplasm diversity based on essential oil composition. Twenty one compounds were identified in V. jatamansi root oil by GC and GC-MS. The major c...
