Sesquiterpene coumarins

Phytochemistry Reviews, 2011
Plants have a long history as therapeutic tools in the treatment of human diseases and have been used as a source of medicines for ages. In search of new biologically active natural products, many plants and herbs used in traditional medicine are screened for natural products with pharmacological activity.

Sesquiterpenes as Immunosuppressants

Transplantation, 2009
The search for new immunosuppressive drugs is a high priority. Sesquiterpenes constitute a family of compounds with a great variety of biological activities due to their reactive moieties.Human tumor cell lines and murine primary cells and human peripheral blood mononuclear cells or primary CD4+ cells from healthy individuals were stimulated in the ...

Sesquiterpene Lactone Allergy

American Journal of Contact Dermatitis, 1996
Sesquiterpene lactones are a large, diverse group of chemicals found in several plant families that cause allergic contact dermatitis. The biological, botanical, allergenic, and structural significance of sesquiterpene lactones is explored as well as the clinical characteristics of cutaneous reactions.

Review of the analytical techniques for sesquiterpenes and sesquiterpene lactones

Journal of Chromatography A, 2002
In this paper the analytical techniques of about the last 2 decades for sesquiterpenes including their lactones are reviewed. For sesquiterpenes, methods like GC, GC-EI-MS, GC-CI-MS, GC-MS-MS, GC-FT-IR, GC-UV, GC-AES, 13C-NMR, PY-GC-MS, HPLC, HPLC-TSP, SFE, SFC, SFC-UV are available, GC combined with MS is the most widespread.

African Elephant Sesquiterpenes

Journal of Natural Products, 1999
GC-MS analysis of extracts from temporal gland secretions of an African elephant has revealed the presence of several farnesol-related sesquiterpenes. Among these are (E)-2, 3-dihydrofarnesol (3), a bumblebee pheromone not seen before in mammals, and a rare component of a Greek tobacco, drimane-8alpha, 11-diol (4), never observed before in an animal.

The first sesquiterpene lactones esterified with a sesquiterpenic acid

Phytochemistry, 1981
Abstract From Hypochoeris glabra two guaianolides esterified with an unusual sesquiterpenic acid were isolated. Proton-catalysed rearrangement of the cyclopropane derivative led to a phenolic acid. The structures were elucidated by high-field 1 H NMR spectroscopy. Further guaianolides were isolated from H. uniflora and Lactuca floridana . These
