Chemical Profile and Antimicrobial Activity of the Essential Oils of Helichrysum arenarium (L.) Moench. and Helichrysum italicum (Roth.) G. Don

Abstract

This study compared the essential oils (EO) composition of Helichrysum arenarium (Bulgarian populations) with that of the cultivated species H. italicum. The EO composition of H. arenarium and H. italicum were analyzed via gas chromatography. In general, 75 components were identified in H. arenarium EO and 79 in H. italicum EO. The predominant constituents in H. arenarium EO were α-pinene (34.64–44.35%) and sabinene (10.63–11.1%), which affirmed the examined population as a new chemical type. Overall, the main EO constituents of H. italicum originating in France, Bosnia and Corsica were neryl acetate (4.04–14.87%) and β-himachalene (9.9–10.99%). However, the EOs profile of H. italicum introduced from the above three countries differed to some extent. D-limonene (5.23%), italicene, α-guaiene and neryl acetate (14.87%) predominated in the H. italicum introduced from France, while α-pinene (13.74%), δ-cadinene (5.51%), α-cadinene (3.3%), β-caryophyllene (3.65%) and α-calacorene (1.63%) predominated in plants introduced from Bosnia. The EOs of the plants introduced from France and Corsica had similar chemical composition and antimicrobiological activity.

Allergic contact dermatitis from essential oil in consumer products: Mode of uses and value of patch tests with an essential oil series. Results of a French study of the DAG (Dermato‐Allergology group of the French Society of Dermatology)

“…Its main components are monoterpene limonene and sesquiterpene hydrocarbons such as α-pinene, α-cedrene, aromadendrene, and β-caryophyllene. 17,18 It is worth mentioning that in one of the reported cases, the patch test with the sesquiterpene lactone mix was also positive, indicating a possible sensitization through this component.…”

“…It is often used in anti-aging products and can help reduce the appearance of fine lines and wrinkles. Overall, H. italicum is a versatile herb with various uses and potential health benefits [ 1 , 2 , 3 , 13 , 14 , 15 , 16 ].…”

Seasonal Variations in Essential Oil Composition of Immortelle Cultivated in Serbia

“…However, due to climate change, many typical Mediterranean plants can now be grown in a continental climate [3]. Because of that, immortelle, as a plant of arid areas [4], can be successfully cultivated in Serbia and Bulgaria [5,6]. As a perennial plant, immortelle is usually cultivated in the same field for five to eight years [7].…”
