Chemical Characterization of Essential Oils With a Biocide Base for Conservation and Restoration

Essential oils (EOs) are acclaimed for their antimicrobial properties, leading to multiple applications in various fields. In this work, four aromatic plants were used, namely thyme (Thymus mastichina L.), everlasting (Helychrysum stoechas Moench), European pennyroyal (Mentha pulegium L.) and fennel (Foeniculum vulgare Mill.). Hydrodistillation was the extraction method obtained extracts composed of a variety volatile molecules, mainly terpenoids phenylpropenoids. The EO yields determined, chemical composition these natural products by gas chromatography-mass spectrometry (GC-MS) analysis. varied greatly range 0.99 4.27% (v/w). two major constituents EOs analysed GC-MS as follows: – 1,8-cineole champhor; ?-pinene limonene; pulegone isomenthone; trans-anethole limonene. This preliminary study is an important contribution understanding bioactive compounds that under investigation establish ability control biocolonization cultural heritage.
