Superheated water extraction is used to extract essential oil of leaves of Origanum micranthum. The effect of different temperatures on the essential oil profile and rate of extraction as a function of time is investigated. The components of essential oil of Origanum micranthum are removed from the aqueous extract by C18 solid-phase extraction. The identification of components is carried out us...

BLANCHE, C. (1990) Delphinium L. subgen. Delphinium: origin and evolutionary trends. Collect. Bot. (Barcelona), 19: 75-95. The advanced features of Delphinium L. subgen. Delphinium (annual taxa) are compared with those of subgen. Delphinastrum (DC.) Wang and subgen. Oligophyllon Dimitrova (perennial taxa). Flower morphology shows a functional interchange between lateral petals and upper petals,...

The tribe Delphinieae (Ranunculaceae) comprises two species-rich genera, Aconitum and Delphinium, the latter including Consolida and Aconitella. The 650-700 species are distributed in Eurasia and North America; three species occur on tropical African mountains. Maximum likelihood analyses of 2088 aligned nucleotides of plastid and nuclear sequences obtained from up to 185 species of Delphinieae...

Sisyrinchium micranthum Cav. is a member of the family Iridaceae, which is distributed over the American continent. In Brazil, this species is found, not only in disturbed areas and coastal regions, but is also very common in urban centers, such as public parks, during the spring. Chromosome counts for North American specimens are 2n = 32 and 2n = 48, whereas in southern Brazil, there is a poly...

BACKGROUND Our aim was to explore the de-addiction properties of Delphinium denudatum Wall. in morphine dependent rats. METHODS Charles Foster male albino rats were made morphine dependent by injecting morphine sulphate in increasing doses twice a day for 7 days. The spontaneous withdrawal signs observed 12 h after the last dose were quantified by the 'counted' and 'checked' signs. The drug (...

Introduction: In our modern era, life style of human being changes and updates every day that may affect their health status. There is an incredible expectation that natural origin drugs lack undesirable effects not like synthetic drugs, though have the same potency and efficacy. No scientific data is available about the antianxiety properties of Delphinium denudatum root and Amaranthus spinosu...

One cleaved amplified polymorphic sequence (CAPS) and nine sequence tagged site (STS) markers were developed for identifying tall larkspur (Delphinium spp.) plants in three species based on the DNA sequence of known species-specific RAPD markers. Four STS markers were used for identification of Delphinium occidentale, three STS markers for Delphinium barbeyi, and one CAPS and two STS markers fo...
