Identification of Volatile constituents from the Flower Oil of Spartium junceum L.
No full textThe essential oil, isolated by hydrodistillation from fresh flowers of Spartium junceum L., was investigated by GC and GC/MS. The 24 main constituents of the samples were identified; the main components of the oil were kairomonal compounds, tricosane (22.9%), tetracosane (8.9%) and pentacosane (16.1%), constituting altogether almost 48% of total composition. These hydrocarbons constitute an important aspect governing the sensitivity of the insects in plant host selection
A comprehensive systematic pharmacological review on Harpagophytum procumbens DC (Devil's claw)
No full textPopularly known as Devil's claw, Harpagophytum procumbens DC. is native to the Kalahari savannas of Southern Africa and Namibia. It has been widely used to treat rheumatism. Its secondary tuberous roots contain iridoid glycosides as the active principles. This species seems to stimulate migration of interleukins and leukocytes to painful and inflamed joint areas. The drug is indicated for osteoarthritis, degenerative diseases of the joints and arthritic processes
Misura non a contatto della temperatura per la stima della diffusività termica a temperature criogeniche
No full textQuality control of aromatic drugs reported in European Pharmacopoeia 3rd edition
No full textThe apparent current explosion of interest and commercial activity in the area of herbal products should be followed by accurate quality control. In this work, the authors carried out the specific quality assays of all the aromatic drugs reported in European Pharmacopoeia. For each drug, several samples of different brands were bought in pharmacies, herbalist's shops, or supermarkets. The worst results were obtained in the assay for the essential oil content and this is very negative as the medicinal activities of these drugs are ascribed to their essential oil content. The samples of different brands yielded very different results from a qualitative point of view. In most cases, the analyzed samples were very far from the acceptable qualitative standards that they definitely lacked any health benefits. (C) 2001 Editions scientifiques et medicales Elsevier SAS
Essential oil from Artemisia coerulescens L. ssp. cretacea (Fiori) Br.-Catt. et Gubell.: analytical composition and new constituents
No full textThe essential oil, isolated from the flowering tops of the Tuscan endemic Artemisia coerulescens L. subsp. cretacea (Fiori) Br.-Catt. et Gubell. by hydrodistillation, was investigated by GC/MS. Fifty compounds were identified, constituting altogether 88.6% of total composition; the presence of 25 compounds in A. coerulescensssp. cretacea oil is reported for the first time. The main components of the oil were αthujone (19–0%), β-thujone (7.7%), camphor (10.4%) and borneol (11.5%). If the oil content is compared with those of other Artemisia species, A. coerulescens ssp. cretacea was found to be extremely rich in oil. © 1999, Taylor & Francis Group, LLC. All rights reserved
