Isolated essential oils as antifungal compounds for organic materials

Abstract Organic industrial materials are exposed to fungal deterioration; prevent this, several additives can be used. In the present work, Egyptian cotton linters, linen textile, and parchment (goat skin) provided from zones in Egypt were The application of eco-friendly essential oils (EOs) isolated Pinus rigida wood Origanum majorana green leaves linter paper pulp (CLP), as bio-fungicides protect against growth Aspergillus terreus , flavus niger was evaluated using inhibition (FGI) assay examined under SEM show extent infestation. By gas chromatography-mass spectrometry (GC–MS) analysis, abundant compounds P. EO determined 2-methylisoborneol (29.52%), 4-isopropyl-5-methylhex-2-yne-1,4-diol (16.53%); O. EO, they cis - ? -terpineol (15.4%), terpinen-4-ol (14.39%), oleic acid (10.75%), D -limonene (8.49%). CLP treated at a level 500 ?L/L with showed higher FGI A. (47.66%), while (74%) (100%). Parchment an 49% FGIs 78% 100% respectively. Linen textile (49%) activity (FGI 77.3%) 100%). images EOs confirmed how these suppressed or prevented molds compared control treatments. findings indicate that considerably enhanced performance CLP, materials; therefore, recommended promising antifungal agents which extend shelf-life materials. This study shows high effectiveness addition natural contain bioactive raw (CLP, parchment) protecting fungi. Subsequently, it is possible deterioration damage prolong their lives long maintaining mechanical specifications materials, especially atmospheric conditions humidity.
