The aim of the present study was to investigate the biological activity of 20 essential oils (EOs) derived from herbal plants and citrus fruits. The in vitro anti-allergic and anti-inflammatory activities of these oils were investigated, and the EO which was found to have the strongest activity of the 20 EOs examined, was investigated further to identify its components and bioactive compounds. ...

BACKGROUND The fragrance compound geraniol is susceptible to autoxidation when in contact with air, and to cutaneous metabolism. In both processes, the isomeric aldehydes geranial and neral are formed. Citral consists of geranial and neral. Among patients with positive reactions to citral, we have previously detected concomitant reactions to geraniol in 85% of cases and to oxidized geraniol in ...

Dracocephalum moldavica L. is an annual species of Lamiacea family whose essential oil is widely used in medicinal, food, cosmetic and health industries. Drought stress is a major factor limiting plants growth and yield. The main objective of this study was to evaluate the influence of irrigation regime on essential oil content and composition of D. moldavica L. The Irrigation regimes were 100%...

Background and objectives: Dracocephalum kotschyi is a plant which belongs to the Lamiaceae family and exists mostly in south-west Asian countries, including Iran. This plant is used as antispasmodic, analgesic and anti-inflammatory to treat rheumatoid diseases. Methods: In order to investigate the impact of the harvesting time changes on the quantity and quality of monoand sesquiterpenoid comp...

The work presented in this thesis emphasizes the importance of considering oxidative activation in the toxicity assessment of fragrance chemicals. Compounds without contact allergenic properties can be activated either via autoxidation in contact with air or via cutaneous metabolism to reactive products which can cause contact allergy. It is important to prevent sensitization as the immunologic...
