Comparison of Antibacterial Activity of Natural and Hydroformylated Essential Oil of Thymus capitatus Growing Wild in North Sardinia with Commercial Thymus Essential Oils / Usai, Marianna; Foddai, Marzia; Sechi, B; Juliano, Claudia Clelia Assunta; Marchetti, M.. - In: NATURAL PRODUCT COMMUNICATIONS. - ISSN 1934-578X. - 5:(2010), pp. 000285487000033.1985-000285487000033.1989.
Abstract:
Thymus capitatus growing wild in Sardinia showed different essential oil composition if grown surrounding Cagliari than in
north Sardinia. Here we verify the composition and antimicrobial activity of the oil to make it suitable for the cosmetic and
confectionery industries. With the aim of improving the scent and the antimicrobical activity of T. capitatus essential oil, a
hydroformylation reaction was carried out to transform the unsaturated components of the oil into the corresponding aldehydes.
The essential oil of T. capitatus exhibited a significant antibacterial activity (MIC 0.125-0.5 mg/mL), and was also found
effective on C. albicans (MIC 0.125 mg/mL). After hydroformylation, several new irregular terpenoid aldehydes were
detected. The perfume of the new terpenic-like aldehydes is very agreeable and, therefore, the acceptability of the aroma is
remarkably improved, but the antimicrobial activity was not increased.
