“…Curcumene isomers were found in a high concentration if plant was collected in winter period. These results are similar with those published by Paolini et al (2006) and Leonardi et al (2013) for plant material collected in Tuscany, as well as in Sardinia (Bianchini et al 2003).…”

Helichrysum italicum (Roth) G. Don is a flowering plant of the family Asteraceae. It is rich in oil that is used for different medicinal purposes and in fragrance industry. Volatile profile of four populations of H. italicum, collected from natural habitat in Dalmatia (Croatia), was analysed by capillary GC-MS. Sample from BraČ Island had α-trans-bergamotene (10.2%) and β-acoradiene (10.1%) as the majors, whereas sample collected on Biokovo Mt. was rich in neryl acetate (8.1%). β-Acoradiene was also the main constituent of sample collected near Tijarica, whereas rosifoliol (8.5%) was the most abundant constituent in sample collected near Makarska. Presented results show the influence of environmental conditions on chemical differentiation of the volatiles of H. italicum from Croatia.

Ethnopharmacological relevanceHelichrysum italicum (Roth) G. Don fil. (family Asteraceae) has been used for its medicinal properties for a long time and, even nowadays, continues to play an important role in the traditional medicine of Mediterranean countries. Based on this traditional knowledge, its different pharmacological activities have been the focus of active research. Aim of the reviewTo provide an overview of the current state of knowledge of the pharmacological activities of H. italicum, as well as its traditional uses, toxicity, drug interactions and safety. Materials and methodsThe selection of relevant data was made through a search using the keywords "Helichrysum italicum" and "H. italicum" in "Directory of Open Access Journals", "Google Scholar", "ISI Web of Knowledge", "PubMed", "ScienceDirect" and "Wiley Online Library". Information obtained in local and foreign books and other sources was also included. ResultsThere are reports on the traditional use of H. italicum in European countries, particularly Italy, Spain, Portugal and Bosnia and Herzegovina. In these countries, its flowers and leaves are the most used parts in the treatment of health disorders such as allergies, colds, cough, skin, liver and gallbladder disorders, inflammation, infections and sleeplessness. In order to validate some of the traditional uses of H. italicum italicum in vivo activity, the highlight goes to the anti-erythematous and photoprotective activities of its flavonoids, demonstrated both in animals and humans, and to the anti-inflammatory properties exhibited by its flavonoids, acetophenones and phloroglucinols, as seen in animal models. Concerning its safety and adverse effects, while H. italicum does not display significant levels of cytotoxicity or genotoxicity, it should be noticed that one of its flavonoids inhibited some CYP isoforms and a case has been reported of an allergic reaction to its extracts.

“…The major terpenes found in EOs are the monoterpenes (C 10 ), but they also contain sesquiterpenes (C 15 ) or even traces of some diterpenes (C 20 ). These compounds are common in essential oils of different plants from diverse families including Asteraceae (Leonardi et al, 2013), Lamiaceae (Herraiz-Peñalver et al, 2015), Pinaceae (Sadeghi et al, 2013), Solanaceae (Murungi et al, 2013), etc. Additionally, recent studies have suggested that the addition of micronutrients and the inoculation of aromatic plants with mycorrhiza can enhance the production of different terpenes as well as other secondary metabolites, increasing the yield of biocidal compounds from natural sources (Yadegari, 2015;Jugran et al, 2015).…”

Essential oil terpenes are secondary metabolites produced in different biological pathways as pollinator attraction signals, but also as defense mechanisms against insect pests, herbivores, microorganisms, competing plants, etc. In this context, we have evaluated a total of 24 terpenes commonly found in Mediterranean aromatic plants, including 8 monoterpene hydrocarbons, 9 oxygenated monoterpenes, 2 esterified monoterpenes, 3 sesquiterpene hydrocarbons and 2 oxygenated sesquiterpenes in order to determine their antifeedant effects on the Colorado potato beetle (Leptinotarsa decemlineata Say), a major pest of potato crops. Terpene hydrocarbons showed low antifeedant activity, whereas the oxygenated sesquiterpene (-)-α-bisabolol with an inhibition activity of 96.3% was the most active, followed by carvacrol (90.9%), (+)-Terpinen-4-ol (87.1%) and thymol (81.5%). Other terpenes like (1S)-(-)-verbenone (72.9%), (+/-)-camphor (63.4%) and linalyl acetate (60.7%) showed moderate activity. Subsequently, terpenes showing antifeedant activity against this insect were also tested in allelopathic assays to determine potential damage to the crops. Results showed phytotoxic effects for (1S)-(-)-verbenone on Lactuca sativa germination, and for carvacrol on both the seed germination and the leaf and root growth of Lolium perenne. In conclusion, (-)-α-bisabolol is the best option to develop natural antifeedant formulations against L. decemlineata on the basis of its high antifeedant and low phytotoxic activities.
